portion of thinning that exceeds the require- 

 ments for tree production and is performed to 

 increase forage production is considered a 

 range practice. 



The work groups first developed strategies 

 by productivity classes and then made adjust- 

 ments by condition classes. Strategies were 

 converted to 100-thousand acre units. Numbers 

 of units of practices needed to attain the goal of 

 the strategy on the individual resource unit 

 were recorded (fig. 6). In developing the strat- 

 egies, the major problem was the use of fer- 

 tilizers. Team members' experience with fertil- 

 izers was limited to small plot research, 



COSTS 



Costs for each strategy were computed based 

 on the constant amount, including 6 percent 

 interest, that would have to be paid each year, 

 even though the amount of capital invested may 

 vary from year to year. Costs were annualized 

 because some strategies required a higher pro- 

 portion of short-lived practices than others, 

 and interest was added to reflect the social cost 

 of selecting those practices that tie up capital. 



For each strategy the annual investment and 

 maintenance costs for selected practices were 

 calculated. Management and supervision expen- 

 ditures were then added. 



The cost of practices for each resource unit 

 was determined from published sources and 

 from experience of selected experts in this 

 field.^ Publications used included Agricultural 

 Stabilization and Conservation Service cost and 

 practice handbooks and USDA research publi- 

 cations on the subject. A cost for doing each 

 practice was determined if the practice could 

 be performed biologically on a resource unit. 

 Since the values were averages, some costs re- 

 ported were obviously higher or lower than 

 average. In developing these values, however, 

 land ownership was found to have no influence 

 on the unit cost or life expectancy of a practice, 

 when the practice was done to the same stan- 

 dard and all elements included. For example, 

 costs on some privately owned land appeared

 practice and basic cost data. Also see "Range Manage- 

 ment Practices: Investment Costs, 1970." (Reference
