GRS Densitometer

Description

Estimate canopy coverage percentages easily! Angled sighting mirror and offset leveling vials allow you to vertically sample forest canopies for a variety of coverage characteristics (e.g. canopy structure, coverage by tree size and species, and percentage of conifer/hardwood). Use to determine non-tree characteristics of sample areas (e.g. percentage of shrub/herbaceous coverage and the grounds condition/soil type). Results are concise, objective and repeatable between observers. Specifications: To determine basic canopy coverage percentage of an area, equally distribute sampling points along a linear transect. At each point, level up the densitometer and peer through the mirror sight to determine if the point is canopy covered. After completing the transect, divide the number of points with canopy coverage by total number of points sampled. The resulting figure is the percentage of canopy coverage for that area.
