As part of our Freshwater Pearl Mussel project we held a community wildlife day at our Afon Eden site in Bronaber. This was a great day where our volunteers helped gather valuable data on invertebrates, water quality and peat health.

The day was filled with various activities aimed at gathering essential data to support the conservation of freshwater pearl mussels, an endangered species who depend on clean water and healthy fish populations.

Volunteers played a key role in this effort by conducting sweep net surveys and kick sampling to collect data on invertebrates, which serve as important indicators of water quality. These methods allow us to assess the abundance and diversity of invertebrate species present, which can provide valuable insights into the health of the aquatic environment.

In addition to invertebrate sampling, the day included water quality testing to measure parameters such as phosphates, pH, temperature, and turbidity. These tests are crucial for understanding the conditions of the Afon Eden and ensuring that the habitat remains suitable for the freshwater pearl mussels and other aquatic life.

Peat health was another focus of the day, with volunteers assessing the condition of the peatland surrounding the river. Healthy peatlands are vital for maintaining water quality, as they act as natural filters, absorbing and storing water while trapping sediments and pollutants. By monitoring peat health, we can better understand how to protect these natural water filters and support the overall health of the river ecosystem.

The community wildlife day was not only about gathering data but also about raising awareness. Volunteers learned about the life cycle of freshwater pearl mussels, their ecological significance, and the threats they face, such as pollution, habitat loss, and climate change.

We look forward to more community events like this, where we can work together to preserve habitat for endangered species.

The Freshwater Pearl Mussel project is funded by LNP Cymru in partnership with Eryri National Park and Welsh Government.
