Ballantine Scale

From Wikipedia, the free encyclopedia

The Ballantine Scale is a biologically defined scale for comparing the degree of exposure of rocky shores; the species present indicate the degree of the shore's exposure.

The scale runs from 1) an "extremely exposed" shore, to 8) an "extremely sheltered" shore.

It was created in 1961 by W.J. Ballantine, of Queen Mary College, London, and the original paper, published by Field Studies Council, which sets out the Scale, is freely downloadable from [1]
