Rangeland health reference sheet
            
Interpreting Indicators of Rangeland Health is a qualitative assessment protocol used to
            determine ecosystem condition based on benchmark characteristics described in the Reference Sheet. A suite of 17 (or
            more) indicators are typically considered in an assessment. The ecological site(s) representative of an assessment
            location must be known prior to applying the protocol and must be verified based on soils and climate. Current plant
            community cannot be used to identify the ecological site.

                of values):

                distribution on infiltration and runoff:
                
              
              

                
Presence and thickness of compaction layer (usually none; describe soil profile features which may be
                mistaken for compaction on this site):

                cover using symbols: >>, >, = to indicate much greater than, greater than, and equal to):

Potential invasive (including noxious) species (native and non-native). List species which BOTH characterize
                degraded states and have the potential to become a dominant or co-dominant species on the ecological site if
                their future establishment and growth is not actively controlled by management interventions. Species that become
                dominant for only one to several years (e.g., short-term response to drought or wildfire) are not invasive
                plants. Note that unlike other indicators, we are describing what is NOT expected in the reference state for the
                ecological site:
