The general licence contains relevant information such as the legal basis and who can or cannot use it. There are also specific rules and conditions. These include limits on the number of birds which can be released and a reporting function for any release of more than 50 birds along with details of any consents (required for the protected site itself) within one month of the release taking place. The system of reporting will be in place by 31st May 2021.
There is also additional advice which is intended to help people comply with the conditions. However, it is advice, and it is not a requirement that it must be complied with unlike the conditions which must be complied with fully.
