NNR visitor survey
If you have been to one of the 143 NNRs managed by Natural England, let us know what you thought of your visit by completing this short survey
Your feedback will be used to help improve our service to you and in deciding how best to manage these reserves for visitors and nature.
If you wish to make a comment about an NNR managed by another organisation, please follow the links from that NNR entry.
Some NNRs host students who are working on dissertations or similar projects. This provides the opportunity to study on a high quality site and to contribute to the research and management of the reserve.
