The Marine Conservation Society does fantastic work. They run all sorts of projects, from beach clean-ups to lobbying the government for more, much-needed, marine reserves. Seasearch is a part of the MCS, providing training for SCUBA divers who want to take part in monitoring Britain's marine life. Anyone who treasures our coastline, our beaches and our marine life can help make a huge difference. Find out more on the website.

One of our best known national institutions, working tirelessly to protect endangered birds and their habitats, not just in Britain, but worldwide. The sea eagles on Mull, which both Simon King and I have spent many hours with, were re-introduced and are carefully monitored by the RSPB. Visit an RSPB reserve and you'll have the best chance to see some of our rarest or more unusual birds. The website is also a mine of information on how to best look after the birds in your garden. Well worth checking out!

Yes, there are seahorses living in the sea around Britain and Ireland, two different species, the spiny and the short-snouted. The British Seahorse survey is dedicated to finding and plotting the populations of our indigenous seahorses in order to protect and conserve these vulnerable and environmentally sensitive animals. The Seahorse Trust aims to help protect worldwide populations. To find out more about seahorses and help with the battle to protect them, go to the website.

If you've ever wanted to get directly involved in the work that conservationists do, check out Earthwatch. They have projects all over the world and as a volunteer you get to experience every aspect of work in the field. I joined a project in northern Ghana a couple of years ago helping set up a reserve and monitor hippos. It was tough; very hard work and certainly not a holiday, but extremely rewarding and there's nothing quite like it for seeing conservation work at first hand.
