we are the voice for wild fish in welsh waters

S&TC Cymru work to secure the protection that our beautiful Welsh water environments deserve. Some of our key achievements include:

Collaborating with other NGO's through Wales Environment Link

Preventing forestry which is damaging to spawning streams

Protecting Welsh rivers via our Riverfly Census monitoring

Preventing sheep dip chemicals lethal to river life

Contributing to the restoration of endangered European eels


Riverfly Census

A benchmark for river life


Water insects are the foundation for life in our rivers and streams.

We are unlocking their potential as indicators of river health to help understand what’s really happening under the surface and better protect our fish and water life.

Our first Welsh samples have been taken in three well-known rivers; keep watch to see how their story unfolds!


Keeping land issues out of water

21a Acid producing conifers planted beside a Welsh spawning stream, one of the issues covered in 'Valuing our Freshwaters' (2)

Activities on land cannot be considered in isolation of the water environment and forestry is no exception to this.

In Wales, non-native conifer forestry next to rivers is a common occurrence, causing numerous issues.

Explore how we have worked to give our watery places and wild fish relief from the effects of poorly operated forestry

Living Rivers

Reviving our watery places


Rivers are more than just water - they are homes for wildlife.

Poor farming practices are a big problem for Welsh waters, but with your help we can create a sustainable water environment.

We are influencing post CAP agricultural grants and subsidies so they are paid as rewards for protecting the environment, particularly in Welsh river systems.
