One of the most dynamic and efficiently run conservation charities I have ever come across. Tusk, as their name suggests, have been instrumental in helping the African Elephant to recover after numbers were devastated due to poaching. They support Lewa Wildlife Conservancy and have recently established the Toki Trust, specifically developed to help meet the costs of ensuring this wonderful cat, and others like him, have a positive future.

Lewa has pioneered a style of conservation in East Africa which has proved to be both effective and sustainable. Run as a not for profit organisation, this privately owned reserve is one of the last places on earth where you can see Grevy's Zebra, Black and White Rhino all drifting across the same plains. I first encountered Lewa when I helped to rear Toki and Sambu, two cheetah brothers who were orphaned further north and brought here with the hope that they might be cared for. I've returned as often as possible ever since.

Simon is closely involved with Lewa via his film projects and is also on the appeals committee.

I have known Pauline Kidner, the powerhouse behind the Secret World, for many years. Her unfaltering determination to care for sick, injured or orphaned wild creatures has often pushed her, and her family, to the point of real personal hardship, but she never, never gives up. Her work with badgers has contributed enormously to the understanding of these enigmatic creatures, and her commitment to exposing the truth behind the bovine TB / badger debate, has greatly influenced the course of events surrounding this thorny debate. Secret World is run as a charitable organisation.

If you are interested in the Natural World, and British Wildlife in particular, you can't afford NOT to be involved in the BNA. This is one of the best respected, oldest and most active organisations concerned with furthering the knowledge of British Natural History in the world. It is a superb forum for exchanging ideas and discovering what new discoveries have been made as well as encouraging younger people to get the wild bug.

Wherever you live, there is a Wildlife Trust near you, making sure that your immediate neighbourhood is as rich in Natural Wonders as possible. The fact that the Wildlife Trusts are all run on a local basis, with, local people at the helm, means that they deal with issues in a manner that is entirely relevant to your doorstep. Join up, join in and help put back something into the very thing that gives us all so much pleasure.
