Description

Sophie Vokes, BSc Geography joins us to discuss her research project "Does Crymlyn Bog follow the traditional theory of hydrosphere wetlands?"

Abstract

This study employed macrofossil analysis to investigate environmental changes in Crymlyn Bog (Swansea) and assessed the site's compliance with the conventional hydrosphere hypothesis of wetland succession. Based on distribution and abundance, macrofossil remains from the peat cores were identified and documented, with a particular emphasis on Sphagnum species. With a delayed decline in Sphagnum austinii and drier conditions near the margin mires, the results indicate a departure from earlier studies. The results further contradict Walker's (1970) hydrosphere theory by indicating a reversal in the predicted successional trajectory. The results have significant ecological implications, as peatlands are crucial hotspots for biodiversity and carbon sequestration. Natural succession changes may result from external factors, such as climate change or internal factors such as hydrological alterations. For the preservation of peatlands and the long-term resilience of ecosystems, these dynamics are crucial. These results relate to the UNSDGs: SDG 6: Clean water and sanitation: through the preservation of wetland health and an analysis of hydrological processes. SGD13: Climate Action: Understanding Peatlands' Capacity to Store Carbon and Adapt to Changing Climates. SDG15: Life on Land can be applied to understand wetland degradation, biodiversity loss, and habitat resilience by examining how it affects biodiversity and ecologically important plant habitats.
