Fisheries & Wildlife
Our rivers and wetlands are home to an enormous variety and abundance of flora and fauna.
Healthy vibrant rivers support healthy fish populations that underpin important recreational and commercial fisheries.
Increasing pressures on our rivers and other aquatic environments are impacting our fish stocks and other valuable and vulnerable native wildlife. Changes to the natural habitat, however small, can have dramatic consequences for native wildlife populations.
Loss or alteration of natural habitat can have a significant impact on the natural balance of the ecosystem and can be a consequence of direct or indirect human interference e.g. removal of natural features or pollution, sediment input, or the introduction of Invasive Non-Native Species (INNS).
Major impacts can have immediate and devastating consequences, but even minor impacts can have significant impacts on wildlife, when considered cumulatively and over longer periods of time.
Fish are a good indicator of ecosystem health and support recreational and commercial fisheries, from both a social and economical perspective.
Therefore, along with other key indicator species, such as invertebrates and plants, it is useful to monitor the composition and changes in fish populations within a catchment, to help develop a picture of how the catchment is functioning and the pressures it may be facing.
Collecting and making information available can help determine appropriate activities aimed at preserving or improving the quality of the environment. Our member trusts take part in various fish and wildlife monitoring programs, to help supplement the information collected by other organisations who operate within their catchments.
