On the use of tree stand parameters in estimating light conditions below the canopy.

Abstract

Especially in forest vegetation studies, the light climate below the canopy is of great interest. In extensive forest inventories, direct measurement of the light conditions is too time-consuming. Often only the standard tree stand parameters are available. The present study was undertaken with the aim to develop methods for estimation of the light climate on the basis of readily measurable tree stand characteristics. The study material includes 40 sample plots representing different kinds of more or less mature forest stands of Scots pine ( L.) and Norway spruce ( (L.) H. Karst.).Pinus sylvestrisPicea abies
