Pin-point method (ecology)
Encyclopedia
The pin-point method is used for non-destructive measurements of plant cover
and plant biomass .
In a pin-point analysis, a frame (or a transect) with a fixed grid pattern is placed above the vegetation. A pin that is inserted vertically through one of the grid points into the vegetation will typically touch a number of plants, and the number of times the pin touches different plant species is recorded. This procedure is repeated at each grid point.
Plant cover
The abundances of plant species are often measured by plant cover, i.e. the relative area covered by different plant species in a small plot. Plant cover is not biased by the size and distributions of individuals, and is an important and often measured characteristic of the composition of plant...
