✦ Synopsis

Some of the problems associated with the use of both percentage cover and cover-abundance scales for describing vegetation are discussed. A transformation, referred to as 'Domin 2.6', is outlined for use with the Domin scale. This transformation allows more accurate estimates of means of Domin scores to be obtained, than are produced by direct averaging of the Domin scores themselves. The transformation is a close approximation to the relationship between percentage cover and the Domin scale and permits rapid transformation of one to the other.

'Domin 2.6' is tested on both simulated and field data. The results show that 'Domin 2.6' corrects for the underestimation of means, calculated by the direct averaging of Domin scores. This is particularly noticeable when widely differing Domin scores are involved. A number of possible uses for this transformation are introduced and discussed.
