About Canvey Wick
Canvey Wick is a truly unique nature reserve on Canvey Island, showing how wildlife can thrive in unexpected places.
Although it was once a brownfield site, it is now recognised as one of the most important places in the UK for rare invertebrates. In fact, it has been described as “a little brownfield rainforest” because of its exceptional biodiversity.
