MANAGEMENT

Economic Aspects of Livestock - Big Game

Relationships as Viewed by a

Livestock Producer*

ERNEST W. CHILSON

Bar T Bar Ranch, Winslow, Arizona

The two words “Ra#nge Manage- ment” in the title of this American Society stand for a great deal and are of national importance because some 160 million people depend in part upon the livestock products that come from the ranges of this country. It is the responsibility of good range mawgement to supply enough livestock to meet the de- mands of a growing population. In view of this responsibility, “The Economic Relationships of Live- stock and Big Game” that we are discussing here today is of impor- tance to every one of us, especially to those of us in the livestock in- dustry.

Big game and livestock are par- ticularly competitive for palatable forage and water in the mountain- ous areas in Arizona. Sportsmen and State Game Department tech- nicians frequently say that compe- tition between big game and live- stock does not exist on good range. It is equally true that competition does not exist between one cow and another when a range is good be- cause of proper stocking. But proper stocking has been achieved by reducing livestock numbers. At the same time game populations have been allowed to spiral up- wards.

The enormous increase in big

game populations during the last 20 years has deprived livestock of their fair share of forage and browse. Range resources could be divided fairly between livestock and big game if such a division were made proportional to the in- vestments and economic contribu- tions made by the livestock indus- try and if such a division were made to meet the needs of an in- creasing population. Let us con- sider some of the investments and economic contributions that are made by the livestock industry.

Investments in Land

Improvements

Arizona differs from the states further north in having very lim- ited supplies of water. There are very few live creeks and rivers. Natural, permanent water avail- able to livestock and big game is trivial compared to developed wa- ter. Due to the small amount of natural water, game increased very little before livestock men started their water development program.

To give an example of how live- stock men have invested in water developments and other land im- provements, I have selected an area in Northern Arizona consisting of approximately 193,000 acres and ranging in elevation from 6,000 to 7,000 feet. I feel the area is a typi- cally controversial livestock-game range because big game graze every

acre. This particular area is 76

145

percent National Forest, 19 percent private land and 5 percent State land. Please keep these percentages

in mind as we see how, and by whom, the water developments were made on the lands. Stockmen con- strutted the following water devel- opments with their own money during the past 20 years: (1) 93 earthen dams, (2) 8 deep wells varying from 450 to 1,050 feet in depth, (3) 29 miles of ditches to collect water and fill the earthen dams, (4) 16 metal or concrete drinking tubs, and (5) several miles

of pipeline. The water develop- ments cost the stockmen of this area $116,000 or the equivalent of 60 cents per acre for the 20-year period. This does not include any maintenance or repair costs.

Now, let us see what the Forest Service, State Land Department, State Game and Fish Department and sportsmen have contributed towards these water developments. The Forest Service, with its limited congressional appropriations, has contributed mainly technical ad- vice and approval. However, on ranges outside this area, the Forest Service has furnished funds for a program of water development.

The State Land Department, the State Game and Fish Commission and sportsmen have made no con- tributions toward developing water in this area. The State Game De- partment has made a number of water developments outside this particula,r area, but in all cases, they were constructed solely for the use of game.

zation. Federal agencies cooperated in the construction of a substantial amount of these fences.

Juniper is presently being cabled on the area at about one dollar per acre. The cost of eradicating ju- niper is being shared by the Forest Service. On other areas, ranges are being reseeded in cooperation with federal agencies.

While these range practices have been aimed at improving livestock * production, they have also in-

creased the production of game. Many reseeded areas that are pro- tected against livestock for the pur- pose of getting a successful estab- lishment of plants a.re used by deer, elk and antelope from the time the plants sprout. Many such areas have had to be reseeded a, second time before a good stand could be established. We may also expect juniper eradication to benefit big game as our present control meth- ods generally do not remove the better browse species. Incidentally, I might comment at this point on the benefits to deer ’ from shrub control in California as was recent- ly reported (Biswell et al., 1952).

It was found that the deer popula- tions on chamiza brushlands opened up by control methods ranged from 40 to 110 deer per square mile; but only 10 to 30 deer were found in the dense untreated brush. The reported ratio of fawns to deer was 115 to 140 per 100 does in the treated area but only 60 to 80 fawns per 100 does in the dense untreated brush.

By continuing these range im- provement practices supported by a suplplemental feeding program, the stockmen have but one goal in mind, namely, better utilization and proper distribution for higher production. Let us take a look at what we have gained or lost in return for our heavy investments in land improvements.

Greatest Benefits to Game Our selected area has had great- er increases in game than is indi- cated by the state averages, because this area is located in Coconino County, a county that supports over half the big game in Arizona.

First, let us look at the popula- tion trends of big game in Arizona in recent years. I believe the first elk hunting in Arizona began in 1935 with 266 permits issued and 145 elk killed. In 1947 there were 1,616 permits issued and 501 elk taken. This was the year tha.t the State Game Department, the Forest Service, and the stockmen agreed to hold elk numbers at the 1947 level. In spite of this agreement, 6,019 hunters killed 1,557 elk in 1953, more than three times the number taken in 1947 and more

than IO times the number taken in

1935. This increase has occurred even though the Game Department has attempted to maintain the 1947 elk numbers by increasing the number of hunting permits.

My records on deer go back only eight years. But these figures are astounding for even such a short period. In 1946 there were 30,827 deer hunters afield, and they took 6,328 deer for a hunter success of 20.5 percent. In 1950 there were 39,353 hunters afield who took ll,- 284 deer for a hunter success of 28.7 percent. In 1953, 53,635 hunt- ers took 18,803 deer for am un-

believable hunter success of 35.1

percent. In other words., there were

three times as malny deer ta)ken in 1953 than were taken in 1946 with an increase in hunter success of 14.6 percent.

For antelope, the State Game Department’s surveys indicate an increase of about 340 percent for the years 1942 through 1953. A very limited number of hunting permits have been issued annually in order to increase the numbers of antelope.

Now, let us see what has hap- pened to livestock numbers in the selected area. Stockmen were al- lowed to graze 5,194 head of cattle on this area in 1937 under Forest permits. Voluntarily, the stockmen have continued to take reductions, until today the permitted number on the Forest is only 2,391 head, a

decrease of 2,803 head or 53 per-

cent.

I cannot say that the terrific in- crease in big ga,me is the sole reason

for the great reductions in live- stock numbers. There have been other factors, such as the encroach- ment of juniper, pinyon and pon- derosa pine into former grasslands. Other land-use pressures have in- creased too, such as logging opera- tions, highways, mining, etc. The Forest Service has been reseeding about half of the most severely disturbed logging areas with some good results.

Stockmen in this general area firmly believe that the tremendous increase in big game is a major factor in forcing the great reduc- tions in livestock numbers. They resent allowing big game to in- crease and replace the livestock taken off the ranges. Isn’t this re- sentment justified in view of the fact that stockmen have invested heavily in range improvements with little or no help from sports- men? This source of annoyance and complaint is further intensi- fied by the public discredit and abuse livestock men have so fre- quently received from sportsmen and their writers. Mutual coopera- tion would be greatly encouraged if sportsmen were to give credit and favorable recognition to stock- men for making land improve- ments that benefit game.

Is it economically sound to per- mit increases in big game to replace reductions in livestock? As stock- men, we say no. Though we are admittedly biased towards operat- ing on a sound business basis, we are trying also to supply a growing population with adequate livestock products.

Since forage and browse re- sources are very limited shouldn’t they be utilized as efficiently as pos-

sible? I do not mean that we should totally remove either big game or livestock. But we should set forth a policy in view of eco- nomic needs that would determine how many game or livestock should be permitted to graze our native ranges.

ECONOMIC ASPECTS OF LIVESTOCK-BIG GAME

for dividing forage resources be- tween domestic stock and big game. Efficiency of production is usually thought of in terms of getting the highest possible net returns in the long run over the costs of produc- tion. The sluccess of a livestock operation is somewhat doubtful when the margin bet,ween net profit

and costs of production is small. This is particularly true where profit depends upon fluctuating . market prices and unpredictable year-to-year changes in weather. Effects of these fluctuating condi- tions on livestock producers have been quite obvious these past two years.

The margin of profit must in- clude a comfortable degree of in- surance a.gainst market changes and years of drought. Actually, this gives the livestock industry the incentive to continually search for ways and means of increasing the efficiency of production and the efficiency of utilizing range re- sources. This, of course, becomes impossible when the carrying ca- pacity or permitted livestock num- bers on a given range are reduced to a point at which the operation ceases to be an “economic unit,.”

Let us try to compare the pro- duction of big game and livestock from an efficiency sta.ndpoint. This is a subject for research experts but we can at least take a look at the surface of the problem.

Because most sportsmen earn their livelihood from many pro- fessions, such as medicine, law, ed- ucation, industrial occupations, etc., they are not too concerned with the efficiency OY producing game and utilizing limited forage and browse resources. They are not too concerned about costs of producing game so long as they can buy licenses and hunting equip- ment.

By contrast, a livestock grower’s costs of production are very real and the amount of his income will depend on how efficiently he can produce livestock.

In comparing costs of produc- tion, let us first consider %bor

and employment.” Labor is an im- portant cost of producing livestock, no matter how small the ranching unit. There is the labor of the own- er himself in addition to the costs of hiring ranch hands, men for range improvements, building con- tractors, bookkeepers, legal advis- ers, etc. There is the cost of em- ploying the tremendous working force for feeding cattle ; the labor force used in processing, transport- ing and marketing livestock and the many by-products such as leather, fats, fertilizers, etc. The livestock industry and the distri- bution of its products to consumers offer tremendous sources of em- ployment.

By comparison, the important costs of labor for producing ganie involve the salaries paid adminis- trators and regulatory officers, whose chief duties are to see that game laws are enforced. The num- ber of people employed in the con- trol and handling of big game herds is very limited. Game pro- vides little employment in such activities as processing and trans- porta,tion. Marketing of wild game is largely illegal except for the game produced by registered game farms.

Hunting, of course, usually in- volves a high cost to most sports- men. But this is the cost of har-

vesting game and includes costly equipment, distances traveled and losses in income or wages when hunters are not on paid vacations.

Costs of Land

Rentals and

Grazing Fees

Livestock men

pay rentals to use state and private lands, and graz- ing fees to use federal lands. By comparison, no rentals or fees are paid for the use which game makes of federal, state or (the use of) most private lands. Hunters pay fees for licenses, and in some areas they pay fees for the privilege of hunting on private ranges. But, do such fees compare to the land rent- als and grazing fees paid by live- stock men? A large part of the fees paid by hunters indirectly goes to paying for administrative, polic-

RELATIONSHIPS 147

ing, and regulatory activities, while only a very small part goes back into the land for improvments that can be used by both livestock and ga.me.

Reductions in grazing fees paid into the federal treasury result when livestock numbers are re- duced in favor of game.

Tax Costs

Ranchers and sportsmen alike pay income taxes and property taxes. The main difference in taxa- tion is that livestock operators pay taxes on a per head basis for do- ‘mestic animals, in addition to prop- erty taxes on private lands and income taxes. We can’t help being proud of the fact that we are about the only industry of agriculture that hasn’t asked for a federal subsidy during t,hese critical times and, therefore, we haven’t been a burden to the taxpayers.

Hunters, on the other hand, do not pay taxes on a per head basis for big game animals.

Reductions in tax revenues re- sult when livestock numbers are re- duced in favor of game.

Cost of Vandalism

Ranchers using ranges that sup- port game herds are faced with the costs of damages resulting from vandalism by some hunters, such as livestock killed; residences and line camps damaged ; windmills, water tanks and troughs shot full of holes ; fences torn down and gates left open, permitting cattle and horses to stray and become lost ; destruction from fires caused by carelessness ; and many other acts which cause permanent dam- age, lost time and money. Sports- men’s organizations have made sin- cere attempts to curb vandalism but the damage continues.

Efficiencies

by Herd Control

bers in periods of drought, market- ing the natural increase yearly, (including females) and using methods for distribut,ing animals evenly over the range. Ranchers aim at high production by con- trolled breeding, a good example being one high quality bull to 15 or 20 cows. Herd controls reduce mortality losses and give high per- centage calf crops.

By contrast, the control of big game herds, being dependent on hunting pressures, is largely in- accurate and haphazard. No real concerted effort is made to reduce game numbers during prolonged periods of drought, or to harvest the natural increas’e yearly. The male to female ratio is normally stabilized at 1:2, 1:3, or 1:4. Such ratios ase considerably less efficient than the male to female ratios for domestic stock. Controls over fawn and elk calf crops are largely left to natural factors. Mortality loss- es among game animals are very high, particularly among old fe- males. Losses inflicted by preda- tors, motorists, diseases, starvation and wasteful killing are high.

Every game animal that is lost or that remains on the range as a mature non-producer represents a waste of forage and browse.

Efficiencies of

Processing

Commercial processing of live- stock products into meat, hides and numerous by-products is organized on a highly efficient basis. It is often said that everything but the “squeal” of an aaimal is used, and now I understand that even the “squeal” is being tape-recorded for sound effects in radio programs.

By contrast, the harvesting and handling of game by hunters is generally very wa,steful. The waste- ful means of harvesting game are described by that well-known sportsman-conservationist, the late Aldo Leopold (1949) :

“It is now a demonstrable fact that Wisconsin deer hunters, in pursuit of a legal buck, kill and abandon in the woods at least one doe, fawn or spike buck for every two legal bucks taken out.

ERNEST W. CHILSON

In other words, approximately half the hunters shoot any deer they see until they find a legal deer and kill him. The illegally killed animals are left where they

fall. Such deer hunting is not only without social value, it con- st,itutes actual training for eth- ical depravity elsewhere.” I do not know what this wasteful killing amounts to in Arizona, but I do know it exists from the cab- casses I have found while riding the range after the hunting seasons are over. Besides wasteful killing, there is the tremendous loss of game meat by spoilage, because of improper care and refrigeration. Few hides of game animals are used. Some trophy heads are mounted.

Wasteful killing and wasteful handling of game meat waste for- age and browse.

Efficiencies of Utilization Animals differ in their efficien- cies for utilizing forage and browse. The da,ily amounts of food eaten by animals involve energy relation- ships and are not directly related to size. That is, larger animals gen- erally make more efficient use of similar feeds than do smaller an- imals. Efficiencies of utilization for severa, different animals are indi- cated by the experimental results of several authorities. (Morrison, 1938; Nichol, 1938; Vorhies and Taylor, 1940, and Arnold, 1942) Reported results show that a 1,000 lb. cow requires 18 lbs. of dry legume hay daily; 1,000 lbs. of live weight sheep require 20 lbs. of similar feed per daily ration ; 1,000 pounds of live weight deer require 23.5 lbs. ; 1,000 pounds of live- weight laboratory rats require 60 lbs. and 1,000 pounds of live weight jack rabbits require about 70 lbs. Domestic livestock thus appear to be most efficient in the use of similar feeds. Efficiencies of utilization such as these will have to be carefully considered in the future if forage and browse re- sources are to b,e used most effi- ciently.

A fair division of forage and browse between domestic livestock and big game, must take into ac- count the following economic as- pects :

Ranchers make heavy invest- ments in water development, fencing, reseeding, shrub con- trol, etc. to improve private, stat,e and federal range lands while sportmen groups make little or no comparable invest- ments.

Big game share the benefits from land improvements made by ranchers while most wa- ter developments constructed by State Game Departments are for the exclusive use of big game.

The management and produc- tion of livestock are more effi- cient than the management and production of big game. A large labor force is em- ployed in the production, feeding, processing, transport- ing and marketing of livestock products and by-products. Game do not provide com- parable sources of employ- ment although the employ- ment by manufacture of guns, ammunition and hunting equipment should not be over- looked.

Livestock producers pay rent- als and grazing fees for the use of ranges not privately owned. Big game, on the other hand, use state, federal and private ranges without charge. Livestock producers pay taxes on a per head basis for livestock while no compa- rable taxes are paid on big game.

It’s an old, old story-overgraz- ing by livestock, denuded ranges, and erosion.

But it is a brand new story-the overproduct,ion of trees can be just as disastrous.

Cattle numbers on the Mud Tank and Beaver Creek allotments of the Coconino National Forest of Ari- zona have decreased by approx- imately 85 percent since 1910. Part of this reduction was neces- sary as there were too many cattle. Ranges were over grazed. A reduc- t.ion of 50 percent should have cor- rected this, but ranges continued to deteriorate. In spite of stock- men’s efforts to make better use of the ranges by water development and fencing, ranges responded, only temporarily, to the reduced. numbers. There is one exception. The lower winter ranges have im- proved substantially.

Further reductions up to 35 per- cent have been made, but the ranges continue the downward trend. Increased game numbers have contributed to this trend, but in my opinion the greatest cause of range deterioration is the unre- stricted, increased growth of trees -cedar, juniper and jack pines, as well as brush.

Cattlemen have known for several

years that they were losing the fight of adjusting cattle numbers to available feed supplies. Year by year the encroachment of trees and brush was choking out the grass. Trees became thicker and larger.

chief gave him another nudge and asked him to move over again. “I can’t move farther. I am at the end of the log.” This illustrates the cowman’s position today. He can’t move farther. He has reached the end.

Grazing of livestock on the forest takes about third place in impor- tance ; water being first and tim- ber second.

Every cowman wa.s striving to build up his herd. In the old days yearlings were sold by the head. It was the numbers that counted. The greater number of yearlings the cowman sold in the spring, the bigger his bank account. Cows were not getting enough to eat. The size of the cow and the yearling were getting smaller. Their stomachs adjusted to the smaller amount of feed. Cattlemen never sold cows. The cows would raise another year- ling, so nature had to do the adjust- ing. The cows died. The ones that survived were small and stunted.

quality trees. One tree, given room, will grow to four or five feet in diameter; fifty trees on the same space can’t grow at all. Like the cow they starve. They die. In the end a few stunted trees remain. It takes several of them to equal the one that has not been stunted. While this process of elimination is taking place, spread over 100 to 150 years, wa,ter is being sacrificed, space for grass is being wasted, and time is being wasted, as a. tree with room grows much faster.

It has been a popular belief that the more trees the more lumber. That’s exactly what the early day cowmen thought about cattle rais- ing. They weren’t considering what the cattle were going to live on, or the damage to the range. And too, it is believed by many people that trees are beneficial and neces- sary on the watershed to increase the water to stream and reservoir. Only in the past year or two has there been a gleam of hope favor- able to the cattlemen. The cedar and juniper thickets, once the pride and joy as a8 soil saver and water conserver, have been pronounced a fake. Not. only do they waste water, but cause erosion as well. They have crowded out the grass, the only true savior of the soil. Thanks to the Indian Service for bringing the above facts to light.

Only recently the Salt River Val- ley Water Users have released to the public their records showing the steady decline in stored water whereas of today the watershed releases for storage only 70 percent as much water as some 45 years ago. These figures coincide with the decline in cattle numbers cov- ering the same period of time. The average annual rainfall remained the same.

D. W. WINGFIELD

We believe the answer to both is the over-production of trees and brush and the accumulation of trash on the forest floor. A tree that can be sawed into lumber is useful and is an asset. A shade tree on a hot summer day is also an asset. The 49 jack pines that never reach the size of a saw log are a liability and should be destroyed. The cottonwood and willow trees lining our streams are extremely wasteful of water.

Trees growing on the watershed are in direct competition with farm crops. For the watershed to de- liver the same amount of water to stream and reservoir as it did some 45 years ago, it is necessary to rid the forest of the surplus trees, underbrush, and trash accumulated over this period of time.

The cost, of controlling forest fires has increased as the fuel to feed these fires has accumulated year by year. When fires were first controlled the floor of the forest was clean. There was very little to burn. For the first few years the local farmers and cattlemen could easily control the fires, and the only weapons for fighting fire were a rake and axe, and some- times a saw.

Much time was spent going to fires, as the men had to ride horse- ba.ck and pack their equipment. Using the same methods today, the control of forest fires would be im- possible. The amount of money spent for the control of forest fires is enormous, but very little is spent to minimize the hazard that causes destructive fires.

There is a happy medium in the use and care of our natural re- sources. Abuse or misuse them and they get off balance. Our economy suffers.

Our goal is not unreasonable. We merely wish to see the preach- ings about multiple-use put into actual practice. We merely recom- mend that federal foresters apply intensive forest management prac- tices on a more widespread scale to benefit not only commercial tim- ber production but also the pro- duction of forage and water. We recommend that thinning, a good but limited forest management practice, be extended. Thinning of dense stands would undoubtedly help maintain a constant supply of forage and would help increase wa,ter yields by reducing the amount of water used and inter- cepted by excessive numbers of trees. We recommend that prun- ing, another good but limited forest management practice, be extended to larger areas, to help reduce the tree canopy that intercepts rain and snow. We recommend the re- moval of excessive numbers of limby wolf-trees that have little or no commercial value and that crowd out forage grasses and waste- fully use and intercept snow and rain. Finally, we recommend the disposal of excess slash and trash on a forest wide basis rather than limiting this forest management practice to the main traveled forest roads. Disposal of excessive slash on a forest wide basis would not only help reduce the fire hazard but would also help reduce the amount of forage that is choked out by heavy piles of limbs and would help reduce the amount of snow and rain that is intercepted and absorbed by limbs and stems which may not rot away even after 50 to 75 years. WR believe that these recommendations would give the greatest benefits to the greatest number.

Combining Pasture Improvement and Carob

Production in Cyprus

D. KENNETH JONES Research Officer, CYP+=S

The concept of improved grazing land composed of grasses and le- gumes, well managed and highly productive without irrigation, is relatively new in Cyprus and in most of the Mediterranean area. The newness of pasture improve- ment in a country with 14 to 23 inches of rainfall may seem sur- prising. However, rainfall occurs only in winter and the dry period extends from May to December with maximum temperatures of 108” F. Add to this the exploita- tion and despoliation of perhaps thirty centuries and a picture of the problem will begin to emerge. Not only are there the’technical difficulties of how to seed and es- tablish better grazing, but also those of trying to evolve systems of management with shepherds whose ancestors have grazed when and where they liked for a hundred generations. Such graziers fre- quently own no land but guard jealously their ancient rights to use, as they will, the stubbles, fal- lows, ranges and pastures of the village community.

Little thought has been given to forage conservation in the past. Indeed, there was little to preserve, so that flock husbandry was and is at a very low ebb. Flocks of sheep and goats have adequate feeding only in spring and early summer. In late summer, fall and winter, the sheep become scaven- gers, growing thinner as the season progresses. Lambing occurs in early winter when the ewes are at a low nutritional level. Changes are tak- ing place slowly with the develop- ment of hand-feeding, increased production of arable forage and its conservation and the present em- phasis on improvement of grazing land.

carob (Holmboe, 1914). The cover of browse, grass and forbs is rela- tively poor in grazing value (Fig.

1).

Carobs are often grown with other crops, usually cereals in a cereal-fallow rotation, so the idea of dual cropping with carobs is not new. The trees are normally grown in a scattered haphazard fashion which suggests that they are rem- nants of an original scrub or Ma- quis flora and grafted at the time of clearing.

The idea of combining carobs with improved grazing is new, how- ever. Since the areas under con- sideration are extensive, low in production and generally unsuited

of growing improved pasture is new and linking it with a well known practice may assist in mak- ing it popular. Competition for moisture between the trees and pasture plants is not considered important. When the trees are planted in rocky outcrops, this could be completely discounted.

FIGURE 3. Pods of carob are flat, inde- hiscent and contain up to 15 seeds.

The Carob

Syria is regarded as the place of origin of the carob but its culti- vation is perhaps most highly de- veloped in Cyprus. This leguminous

tree, when grafted, produced thick, fleshy pods up to one foot in length. It is found on Mediterranean coast- al areas as a common constituent

of the Maquis or scrub forest as a native tree or low-growing, grazed bush (Fig. 2). Commercial stands may be established by grafting wild trees with improved varieties or by establishing seedling trees and grafting subsequently (J o n e s, 1953).

The pods are widely used for cattle feeding and are becoming more popular for human food (Fig. 3). A gum in the seeds is used widely in confectionery and in- dustry. However, the whole pod has too much carbohydrate to give

a

balanced animal diet (Watson and More, 1937). Fairly produc- tive trees can be grown on very rocky and poor sites provided root penetration is possible and drain- age is free. All soils in Cyprus are alkaline, so the reaction of carob to acid soils is not known. It can tol- erate a few degrees of frost but normally does not grow well above 1,300 feet.

The Pastures

The major pasture species are: corn brome (Bromzcs squarrosus

var. viZZosus), Madrid brome (B.

madritensis), ovate goatface grass

( Triticum ovatum), big quaking

grass (B&a maxima), Spanish or- chardgrass (Dactylis glom‘eratus

ssp. hispanica), bulbous bluegrass

(Poa bulbosa var. vivipara), smilo

( Oryxopsis miliacea), asphodel

(Asphodelus ramosus), star clover

(Trifolium stellatum), hop clover

Production is low and fluctuates so widely with season and manage- ment that actual productivity is difficult to assess. Moreover, actual grazing capacities of areas used for grazing are difficult to estimate, since they are utilized in conjunc- tion with stubbles and fallows. The production obtained from clearing and reseeding is so markedly su- perior to the existing cover that yield comparisons of before and after treatment are hardly neces- sary to demonstrate the need for improvement.

Many of the areas available for reseeding are characterized by Terra Rossa soils. These areas often have a discontinuous surface of hard limestone of varying thickness over the soft, chalky parent ma- terial. The thin soils occur as patches interspersed with and overlying the hard cap (Fig. 4).

Establishment of the Carob Techniques for establishing car- obs are well known and have been detailed by Jones, 1953. Year-old seedlings are planted in 2 x 2 x 2 foot holes or wild trees are grafted in place. In areas with the lime hardpan, blasting may be neces- sary (Fig. 4, rt.). During the first summer, seedlings should be irrigated and mulching is advis- able.

Establishment of Pastures Improved management alone is not sufficient to promote forage re- covery, as the climax vegetation of the area is forest. Deferment per- mits increased tree and shrub growth so that brush control is a primary consideration. Burning programs may be restricted by the presence of wild carobs needed for grafting. These trees may be pro- tected by clearing lo-foot areas around the trees prior to burning.

Establishment of seeded pastures requires proper methods of seed- bed preparation. Reseeding in the ash following burning has not been

successful. Cultivation is essential as a method of weed control and as a method of covering the seed to avoid losses from harvester ants. Cultivation implements range from the biblical wooden plow to the D-6 Caterpillar with a ripper attach- ment. A light covering of the seed may be achieved with the primitive harrow of the Near East, a flat board, to which brushwood is at-

Seeding prior to rains has not been successful because of weed competi- tion with the sown species. Delayed sowing limits the growth made be- fore the minimum temperatures of February. Date of seeding is par- ticularly important for species of slow germination and poor seedling vigor such as smilo (Jones, 1954).

tached.

Date of planting is important. Ideally, seeding should be done in early December, following the first rains of mid-November on August burns. Weeds which germinate fol- lowing the initial rains are plowed in and clean stands are obtained.

field grazing trials. Mixtures of a single grass and legume have been tried, as well as mixtures contain- ing several species. The most suc- cessful mixture has been barrel medick (Medicago tribuloides) and Wimmera ryegrass (Lolium rigid-

urn) (Fig. 5, upper). Establish-

ment is not difficult and both are naturally aggressive in re-establish- ment from seed under proper man- agement.

Perennials such as Harding grass

(Phalaris tuberosa), smilo, or-

chardgrass, veld grass (Ehrharta

calycina and E. longifiora) and

bulbous barley (Hordeum bulbo- sum) are very definite possibilities (Fig. 5, lower). Successful stands, totalling some fifty acres of the first two species, have been made. No suitable perennial legume has been found. Alfalfa grows without irri- gation, but production is poor ; san- foin (Onobrychis satiwa) looks good in small plots but its field behavior has not been evaluated.

Utilization

Light grazing can be obtained on areas seeded to annuals, but the growth of perennial species is slow and grazing is not advisable during the first year. Seeding of annual legumes at the same time as per- ennial grasses may require modifi- cation as the legumes may offer strong competition with the slow- growing perennials. Seeding the legume during the second year is being tested, using the almost in- destructible pods of barrel medick rather than the threshed seed. This legume can be seeded in summer as the pods are too large for harvster ants to remove and soil cover is un- necessary. The high cost of seed may be a limiting factor as only

one or two seeds per pod germi- nate.

The carob produces fruit five years after grafting but maximum yield is reached at 20 years. Ob- viously, introduction of grazing animals in young carob plantations is a risk but injury may be mini- mized by the provision of a guard of thorny brush or stakes around young seedlings. Grafting may be done at a height out of reach of sheep and goats. In Cyprus, har- vesting is carried out by knocking the pods from the trees; if left to fall to the ground, they can provide feed for livestock.

Costs

and R&urns

On favorable sites, the cost of planting carob seedlings is about $50 per acre; where blasting holes is necessary, costs may be some- what higher. Grafting established wild stocks may cost only a few cents. The present overall cost of establishing p a s t u r e, including burning, cultivating and seeding, amounts to $18 per acre but this may be reduced with more experi- ence and on larger areas.

Maximum production, reached in about 20 years, would provide re- turns of $41 per acre per year, based on an average yield of 56 pounds of beans per tree, stands of 2’7 trees per acre, and a purchase price of $61 per ton of beans.

Returns from reseeded pastures are somewhat variable as shown in the early pilot tests. In the 1955 grazing season, a typical area re- seeded with Wimmera ryegrass and barrel medick gave a gross return of $61 per acre based on produc- tion of wool, meat and milk and maintenance of sheep at prevailing market prices. In terms of sheep

grazing, this represents 384 days per acre.

It is obvious to even the casual observer that present production from large areas of Cyprus is very low and that reseeding may bring phenomenal increases. However, it must be emphasized that the scrub flora may regenerate readily with incorrect management (N a v e h, lg54). Large scale projects must be approached with caution until further experience is gained.

Summary

Increasing production in typical Maquis scrub of the Eastern Medi- terranean through combining carob growing with improved pastures is described.

Methods of establishing carobs and reseeding are outlined. Grasses and legumes suitable for reseeding cleared scrub land are listed.

Dual cropping of carobs with cereals in a cereal-fallow rotation is commonly practiced in the area. An extension of this practice to scrub areas, in which improved pasture replaces arable crops, is advocated.

Range Waterspreading as a Range

Improvement Practice’

ROYALE K. PIERSON

Rage Officer, Bureau of Lawd Managernewt, U. 8. Dept. of Interior, Washabgtoq D. C.

Waterspreading as applied to rangeland is a multiple-purpose practice having as its primary ob- jectives the control of soil erosion and the conservation of moisture. Associated benefits are sediment retardation, increased forage pro- duction, restoration of ground- water levels, stream flow regula- tion and improvement of wildlife habitat. Ephemeral runoff is di- verted from eroding channels and spread over adjacent floodplains or valley floors. The principal diver- sion structure is usually placed upstream above the advancing headcut, permitting the gully to become stabilized and revegetated.

Waterspreading is a crude form of irrigation practiced since time immemorial to provide sufficient moisture for crops in moisture-de- ficient areas. It was used in South- western United States by the In- dians long before the coming of the white man. Early ranchers in the Northern Great Plains employed waterspreading to increase forage production on native hay lands and winter ranges.

Present day waterspreading dif- fers from that practiced by the ancients only in the refinements in design through modern engineer- ing and hydrologic techniques. It is similar to “wild flooding” in crop irrigation practice, in that a mini- mum of control is applied to the water source or to obtaining a uni- form spread of water over the land surf ace.

The degree of control applied to spreading water is governed by fac- tors such as the smoothness of the spreading area; the gradient ; the 1. Address presented at Eighth Annual Meeting of American Sooiety of Range iManagement, San Jose, California, Jan- ualy d7, 1955.

area available for spreading; the volume of water; and the char- acteristics of the soil in the spread- ing area. Arguments have been ad- vanced for placing emphasis on the simplest form of spreading sys- tems, although there are equally valid arguments for installing more complex controls where the condi- tions permit and there are obvious advantages in the utilization of all the runoff water available.

Current Studies

Much has been said and a great deal written about waterspreading on rangeland but despite the vol- ume of verbiage we have very little information that enables us to pre- dict the exact influences of water- spreading on the range environ- ment. The range conservationist must rely to a great extent on em- pirical methods and his personal experience when installing a water- spreading system and attempting to forecast the results.

Hubbell and Gardner (1950) summarized the results of nine years of study of waterspreading at Mexican Springs on the Navajo Reservation in New Mexico. They concluded that waterspreading is an effective means of transporting sediment to areas where it can be stored in the watershed, preventing its movement to downstream water- storage reservoirs. On the basis of clipped plots, forage production was increased from three to nine times the volume produced on com- parable unflooded areas. They also verified the observation, made by ranchers in the Northern Great Plains many years previously, that western wheatgrass (Agropyron,

smithii) would survive a rapid dep-

osition of more than five inches of sediment, a depth that damaged

155

all other range grasses. The work at Mexican Springs is the most comprehensive published to date.

More recently the waterspread- ing experience of the federal Agri- culture and Interior Departments was assembled in the form of a manual at the request of the For- eign Operations Administration (1954). The purpose of the manual is to provide a technical subject- matter guide for the use by Ameri- can technicians on foreign assign- ments, particularly technicians in the Near and Middle East. This manual has also been translated into Arabic for the benefit of non- English speaking technicians in some of these countries. While the manual represents an inter-agency effort in assembling waterspreading technology, it is doubtful whether the methods described will find widespread acceptance among all technicians in the contributing agencies.

Currently, the Geological Survey is conducting detailed basic-data investigations on waterspreading systems installed by the Bureau of Land Management on public lands. The systems under study are locat- ed on Willow Creek and the Little Missouri River in Montana, Muddy Creek in Wyoming, and Badger Wash in Colorado. The studies in- clude the influence of waterspread- ing on stream flow and ground- water ; moisture infiltration and soil

permeability; rates and depths of moisture penetration in relation to storm intensity ; and the relation of soil chemistry to the success of spreading systems. It is interest- ing to note the extreme variation found in infiltration rates on in- stalled waterspreading systems, ranging from a trace to 6 inches of water intake per hour as de- termined by ring infiltrometers.2 Also, infiltration rates appear much higher on well-grassed flooded areas than on similar adjacent soils not subject to flooding.

dividual watersheds, are aiding the Bureau of Land hIanagt7nrnt in the design of more efficient and economical spreading spstems. As more data are accumulated it will be possible to drtmmine in ad- vanee, with some pm&ion, the hydraulic and water retention characteristics of designed systems and in turn predict the probable influences on the watershed.

Increasing Range Forage As a range improvement prac- tice, water-spreading is n means of restoring the productivity of valley lands that once were the key arms of range use. Because the forace on these lands is usually more pal- atable and in greater abundance, these areas bore the brunt of the heaviest grazing use and were the first to show the effects of excessive grazing. Later, as the uplands were grazed equally as heavily, aeceler- ated runoff flowing through once protected channels in the mlle,v floors soon eaunrd excessive channel scouring with subsequent deepen- ing and widening of gullies and ultimate dmtruction of the valley

fills. Frequently the rehabilitation of the kry grazing meas in the valley is the only salvation for re- storing the upland ranges aud re- tarding flood runoff into the valley gullies.

R,ange vatersprmding has oeca- sionally resulted in wnsational in- creases in forage production at- tracting the attention of range users and the public alike. There are examples of waterspreading on the public lands IThere barren flats of negligible grazing capacity have been converted to dense stands of grass hariny a grazing capacity of one acre per A.IJ.M. Lowyirlding mat SdtSS,oe range has been eon-

rrrted to grassland approaching the characteristics of hay meadows. These examples arc the exceptions, representing optimum eombina- tions of site factors for maximum vegetal response. A more realistic view of forage production by materspreading would place the in- crease at from three to five times the former grazing capacity, de- pending upon the range type and frequency of runoff through the system.

Ocr;tsionally, the initial success of waterspreading can be attrib- uted to the leaching of soluble salts from the upper soil layer by flood- water. If the internal drainage of the soil is drficicnt, the success will be short lired since subsequent floodings will soon increase the salt content in the upper layer from zonks of accumulation in the sub- soil. More typically, and if care is used in selecting the spreading area, the first run of mater through a ner s,vstem mill carry surface s&s drrp into the subsoil and sub- sequent runs mill continue a down- ward leaching. The first run of umtrr Till aid vegetation only on the area actually flooded. Subse- quent runs will gradually build up the subsoil moisture until the vege- tation shors a fairly uniform re- sponse over the entire spreading area. This sequence of behavior is more typical of spreading systems on fine-textured soils in the North- rrn Great, Plains where several rllns of Inter occur each year.

Management of Spreading Areas Ranges improved by water- spreading should become an inte- gral part of the managemer~t plan for the area. Where precipitation and runoff are reasonably depend- able, the spreading area may serve to meet a specific management de- ficiency such as supplementing summer or rinter range or in pro- riding the seasonal forage require- ments for a particular age class of liwstock. Under these circumstan- ces the spreading area is usually fenced and treated as a separate management unit.

(16)

Spreading areas bearing peren- nial forage plants must he carefully

utilized in order to maintain R thrifty vigorous cover with a mar- gin of strength to surrive the prri- odic shock of prolonged inundation and heavy sedimentation. If pos- sible. livestock should be excluded during flooding to avoid compact- ing the wet soil and to givz thr forage plants an opportnnity for maximum response to the addi- tional moisture. More intrnsirr management practices can be ap- plied to the spreadinn area be- cauw of its limited size and high level of forage productivity.

Cost of Waterspreading

No discussion of range improve- ments is complete without some reference to costs and the question may logically be asked whether watrrsprmdiny is a paying propo- sition. A full-blown rconomie feasibility analysis v~uld inrolre an allocation of costs among the various purposes to be served bv thP spreading system, such as sedi- mrnt control, forage production and stock water. Also, values nonld have to be determined for ezach of the direct and indirect benefits rewlting from the project. A simpler and more direct np- proach would consider only the in-

crenad forage value on the basis

of eurrent comparable market prices. similar to the method em- ployrd in appraising real estate.

Katrrsprrading costs in the I%ureau of Land Management hare ranged from less than onr rlollnr to as high of $20 per axe, depend- ing upon the complexity of the system and the amount of con- struction involved. When convert- ed to animal units of forage these costs have varied from $30 to $120 per animal unit of new forage. Sales of private range on a forage basis made in recent years have fluctuated widely, due to specu- lative elemeuts, some going as high as $300 per animal unit but mostly in the neighborhood of $150. When waterspreading costs are compared with sales priws it would appear cheaper for the operator to create

nrw forage prodnction thall to pur- chase additional land, providing, of IX~TSC. that he has snitable areas for materspreading.

Selection of Suitable Areas Khile xaterspreading has prob- ably received an unvarrantrd amonnt of publicity an a cure-all for dpplrtrd ranges, the area snb- ject to improvement through this prartice is necessarily limited to locations fa\~orrcl by witable top- ographic and other physical at- tributes. It has been estimated that thr total area of public land suitable for waterspreading is less than 3f/~ million acres of which about 750,000 acres have been de- wlopcd to date. X0 current esti- mates are arailable on the wea. of land in other onmerships avail- able for waterspreading. Provided no conflict in use of land exists, the first fartors governing selection obviously are a supply of water and a suitable area of land on which water can be spread at a rrnsonabl,v uniform rate. General- sly, the slope of the RI‘CR should not

exceed 3 percent bnt here again soil prrmrability and smoothness of the area will d&rmine how steep 01‘ how flat the area can be. In considering the water supply, a prwipitation pattern in which most of the rainfall oeeurs during

th? grovin,n season offers the best opportunities for watrrspreading. Areas subject to summer thunder showers and rain storms of high intensity, such as w-e typical of some of the western states, usuallr are the most advantageous for watersprrading. This statement does not rule out valuable spread- ing results on sagebrush lands of the Pacific Northwest with rainfall principally in the winter.
