2. Land Health Surveillance (LHS): LHS is a framework developed by the United States Department of Agriculture (USDA) to assess the health and condition of rangelands. It considers indicators such as vegetation composition, soil stability, and hydrological function.
3. Ecological Site Description (ESD): ESD is a standardized approach used by land managers to assess the ecological condition and potential of a specific site. It considers factors such as plant community composition, soil characteristics, and disturbance history.
4. Grassland Condition Assessment (GCA): GCA is a method used to evaluate the condition and trend of grasslands. It typically includes indicators such as plant diversity, soil nutrient levels, and invasive species presence.
These standards provide comprehensive frameworks for evaluating grassland degradation and can be adapted to specific contexts and regions. It is important to select an appropriate standard based on the specific goals and requirements of the assessment.。
