Sophie works on two main projects, both incorporating alternative silvicultural systems into modelling tools to help forest managers. The first project involves expanding the existing ForestGALES model, which predicts risk of wind damage in coniferous monocultures, to include several broadleaf species and risk to individual trees in irregular stands. The second project is the development of a single-tree growth model (MOSES_GB) for the simulation of non-uniform forest stands, such as those that will result from the increased application of continuous cover silviculture. Prior to this, Sophie worked on measuring and modelling under-storey light regime, linking stand-level parameters to light levels and seedling growth. This work will help to inform regeneration dynamics within MOSES_GB.

Sophie Hale joined Forest Research in 1997, after obtaining a degree in Geography and a PhD in forest micrometeorology from the University of Edinburgh. Her research links silviculture with the development of modelling tools to aid forest management, focusing on growth and stability of irregular forest stands.

This Information Note summarises the light requirements for seedling growth of conifer species beneath a forest canopy, and describes how to assess whether light levels beneath a stand are limiting seedling growth. Various methods of assessing light and canopy openness are described.
