Abstract

A simple, inexpensive, pocket-sized cover meter for estimating both canopy and basal cover is described. The cover meter is based on the visual superimposition of canopy-to-gap ratio scales, on to vegetation. Tests indicate that, in certain vegetation types, accuracy is comparable to the wheel-point apparatus in estimating basal cover. Canopy cover is estimated in classes according to the Domin-Krajina cover-abundance scale.
