The RSPB is a charity, founded in 1889 and run by a Council of volunteers. Wildlife is facing huge challenges. Species are dying out, climate change is affecting the environment and pressures on land are growing. What are we going to do about it? Reserves are at the heart of what we do. They’re vital to our conservation work and priceless spaces for everyone to get close to nature. We believe they work best when they connect with wild spaces and habitats in the wider landscape. That’s why we’ll be working to make bigger, better, more joined up homes. We base our work on good analysis of the threats facing birds and the environment. We see a problem, work out what is causing it, and find ways to put it right.
