Cromwell Bottom is considered to be one of the most important wildlife sites in Calderdale.

The wetlands and meadows provide a variety of habitats for many insects, such a Dragonflies and Damselflies, though not a huge amount of dragonflies have been seen at the time of writing (July 2020).

We welcome any input from people who visit the reserve and please email us with your findings and photos.  Photos on this page are from Allan Wolfenden, Graham Haigh, Mike Henshaw and Val.
