If you are interested in recording your wildlife sightings there are plenty of apps and websites where you can do this. Much of this data is then shared across the UK’s wildlife conservation organisations, government agencies and voluntary groups via membership of the National Biodiversity Network; a collaborative project that facilitates the collation and sharing of this data.
The National Biodiversity Network provides information on how to get started with identifying and recording species so I would recommend visiting their site. However, here are links for some of the main places you can submit your sightings.
