Wildlife encouraged

We have successfully encouraged wildlife habitats on our reserve:

  • Birds, including barn owls and kestrels, have made use of purpose-built nest boxes.
  • Water voles are making themselves at home in new wetland habitats.
  • Many invertebrates live amongst the reed beds, as do wading birds.

Community events and open days

Through our Friends of Crossness Nature Reserve scheme, we offer a wide range of community events and open days to introduce our unique area, plus talks and guided walks to raise awareness a new environment.

Several events are held through the year, in the past these have included a:

  • Water vole awareness day
  • Moth identification night
  • Bird ringing demonstration
  • Bat walk
