32. Standards and Guidelines
1. Sufficient cover and litter to protect the soil surface from
excessive water and wind erosion, promote infiltration, detain
surface flow, and retard soil moisture loss by evaporation
USFS Objectives for Range Management
1. Manage range vegetation to protect basic
soil and water resources
