Impacts of Climate Change on Mountain Ash Species Composition
The transformation of Mountain Ash forests is expected as a result of climate change. Burnt or disturbed Ash forests struggle to recover compared to mixed species forests, which are gradually moving into areas currently occupied by Ash species. This shift in species composition is driven by the inability of Mountain Ash species to adapt to climatic stress, particularly in warmer and drier conditions. The changing species composition highlights the need for conservation efforts and adaptation strategies to ensure the long-term resilience of Mountain Ash ecosystems.
As Mountain Ash forests face the challenges posed by climate change, the composition of these forests is undergoing significant alterations. Burnt or disturbed areas that were once occupied by Mountain Ash species are experiencing a slower recovery compared to areas with a mix of different tree species. Consequently, mixed species forests are gradually encroaching upon Mountain Ash habitats, leading to a shift in species composition.
Mountain Ash species face difficulties in adapting to the stress brought about by climate change, especially in warmer and drier conditions. This inability to adapt to climatic variations further exacerbates the challenges faced by Mountain Ash forests. As a result, the resilience of Mountain Ash ecosystems is at risk.
