This poster outlines upland tree regeneration monitoring which was initiated at Corrour Estate in summer 2020. It aims to understand the impacts of reduced red deer densities on different tree species across a range of habitats. Records of growth, browsing and vascular plant species richness were included. Tree distribution was linked to habitat type, altitude and proximity to existing seed sources. The work will be repeated every 4 years and also contributes to the PhD project “Improving outcomes in montane woodland restoration” at the University of Stirling.
