WHAT WE DO
Biodiversity
Protecting and understanding the rich variety of wildlife that depends on the River Foss.
A Living River Corridor
From its rural beginnings to its journey through York, the River Foss provides an important corridor for wildlife. Its waters, banks, trees, plants and surrounding habitats support a diverse range of species.
Birds, bats, fish, mammals, aquatic invertebrates, dragonflies, damselflies and a wealth of plant life can all be found along the Foss. Understanding what lives here — and how those populations change — helps us recognise the importance of protecting and improving the river's habitats.

Understanding and Protecting Wildlife
The River Foss Society has a long-standing interest in the natural environment of the river. Our activities include wildlife observations and surveys, monitoring species and habitats and supporting practical work that benefits biodiversity.
The Society has also worked with other environmental organisations and specialist ecologists to study the changing biodiversity of the Foss, including its plants, vertebrates and invertebrates. This knowledge helps build a better understanding of the river as a complete ecosystem rather than simply a channel of water.

Exploring Life Along the Foss

Wildlife
Discover the species that call the Foss home
From birds and bats to water voles, fish and aquatic insects, the river supports wildlife both above and below the water.

Plants & Habitats
Protect the places wildlife depends upon
Riverbanks, trees, aquatic vegetation and surrounding green spaces provide food, shelter and important connections between habitats.

Observe & Record
Help us understand a changing river
Wildlife observations and surveys build our knowledge of the Foss and can help reveal changes in species and habitats over time.
Help Protect Life Along the Foss
Whether you are an experienced naturalist or simply enjoy spotting wildlife, there are opportunities to learn more, share observations and help us understand and protect the river's biodiversity.
