Table J27 Mixed Mountain Shrub/Dark Brown Loams (Mixed <br />Mountain Shrubland) <br />Table J28 Grassy Bald Ridges/Shallow Gravelly Loams <br />(Mountain Grassland) <br />Table J29 Shrub-Grass Rockland/Shallow Stony Loams (Indian <br />Ricegrass) <br />Tiedman and Terwilliger (1978) have no phyto-edaphic unit close <br />enough to the Greasewood unit as it exists in the permit areas <br />to justify presentation of standing biomass figures. Thus, her- <br />bage production from this unit is best inferred from the Salt <br />Flats Range Site Description (U.S. Soil Conservation Service, <br />Range Site Description #262). For an area in excellent condition, <br />production is expected to range from 900 pounds/acre air-dry in <br />favorable years to 500 pounds/acre air-dry in unfavorable years <br />with 650 pounds/acre air-dry in medium years. It should be noted <br />• that the Greasewood communities are probably in only poor to <br />fair range condition based on data in Table J9, therefore actual <br />production is much less than that cited in the range site <br />description, <br />No estimates of standing biomass or annual forage production fig- <br />ures are available for the Riparian Woodland, Sparsely Vegetated <br />Rock., or Disturbed Site mapping units, largely because these units <br />have no signifcant forage production available for livestock. <br /> <br />r, <br />U <br />J-16 <br />
