Infiltration Rates and Sediment Production of Selected Plant Communities in NevadaInfiltration rates and sediment production of 29 plant communities and soils on five rangeland watersheds were studied in central and eastern Nevada. Three inches per hour of simulated rainfall was applied to soil initially dry and to soil initially at field capacity. Infiltration rates and sediment production for the various plant communities and soils varied considerably within and between watersheds. Highest infiltration rates and lowest sediment production occurred on sites with well-aggregated surface soils free of vesicular porosity.
Returns to RangelandsGross value of production from western rangelands average$7.46 per AUM based upon aggregate data from Wyoming, Utah, Nevada, and Oregon for 1966-70 and reached about $10 per AUM in 1972. Privately owned lands leased on an acreage basis but with the lease expressed on an AUM basis generally leased at $1.50 to $2 per AUM during 1966-70 and a little over $2 per AUM in 1972. Returns to rangeland estimated from published research by a real estate appraisal approach in which returns are imputed from an income statement were comparable to the lease rates. The imputational procedures in arriving at returns to land and the definition of an AUM should both be standardized for better comparisons among diverse areas or ranching types where animal-size and herd composition vary.
