GRS is the designer and manufacturer of the Densitometer, a tool for the estimation of vegetation cover. The GRS Densitometer, when used with line-point transect sampling, combines horizontal and vertical vegetation sampling, thereby enabling the collection of resource information across the landscape (horizontally) at different canopy levels (vertically). This technique provides estimates of cover for any element in a forested environment such as: trees, shrubs, herbs, downed-woody material, fuels, and snags. This method of sampling has been shown to be accurate, objective, and repeatable between observers.
