Influence of light regimes natural replacement in the stands of beech and fir (Abieti – Fagetum) at Kozara

Abstract

Hemispherical photography is one of the techniques that is used for indirect evaluation of light climate in forest stands. As the answer to the theoretical introduction in the method that is based on literature an experimental examination of light regime and seedling regeneration was carried out in Abieti–Fagetum forest at national park of Kozara. The elements of stand structure were measured and seedling density was counted at the chosen sample plots where photographs were taken in early morning and midday hours. Light environments on the sample plots were evaluated using computer program Gap Light Analyzer version 2.0., and the results of the evaluation were subsequently related to the density of silver fir and beech seedlings.
