Abstract

In this paper, we develop models to describe light environment edge effects in retained mountain ash/riparian forest in southeastern Australia following edge creation by clearfell logging. The models are then used in the design of functional buffers whose objective is light environment protection. The study uses hemispherical photographs taken before and after logging at distances from the cut edge ranging from 0-108 m and at heights above ground of 1, 3.4 and 6.8 m. Non-linear regression was used to develop relationships between the change in light penetration due to edge creation and distance from the edge. Vegetation and topographic variables were evaluated as additional explanatory varia..
