The best wildlife charities
Behind every elephant still roaming free and every whale breaching offshore is someone looking out for it: the rangers clearing snares, the keepers caring for rescued animals and the scientists counting what's left so it can recover. It's patient, determined work, and it means the world's wildlife still has a fighting chance.
Four charities, each brilliant at a different part of the job.
Rather than a ranked list, we've picked a range of charities, so together they cover more than any one could alone.
WWF-UK
- Threatened Species
- Wild Places
- Global Network
WWF-UK was founded in 1961 as the World Wildlife Fund, by a group that included Sir Julian Huxley and Sir Peter Scott, who drew its famous panda logo. Today it's active in the UK and nearly 100 countries, protecting threatened species from tigers and elephants to penguins and polar bears. It works hand in hand with governments, businesses, Indigenous peoples and local communities. It thinks on the scale of the whole planet, which is exactly the scale nature needs.

Born Free
- Rescue & Care
- Anti-Captivity
- Wildlife Trade
Born Free began in 1984 as Zoo Check, founded by Virginia McKenna, Bill Travers and their son Will after the death of Pole Pole, an elephant from one of their films. Today it rescues wild animals from captive exploitation, cares for them for life in spacious sanctuaries and campaigns against trophy hunting and the wildlife trade. It also helps communities in Kenya live alongside wildlife. Its message hasn't changed in 40 years: keep wildlife in the wild, and we couldn't agree more.
