Methods to Determine Utilization

Many methods have been developed to estimate utilization, but few have proven suitable for all situations. Depending on the objectives of the inventory or monitoring program, sampling may concentrate on describing utilization for several key species, or it may aim to describe grazing impacts on the entire forage resource.

The following sections describe several widely adopted approaches to estimate utilization.
