Welcome

The International Otter Survival Fund (IOSF) is one of the world's leading otter charities. In the UK IOSF is the only charity solely dedicated to the conservation, protection and care of otters based on years of scientific research in the UK and around the world.

Otter numbers in the UK have increased slightly in recent years but the Eurasian otter is still classed as “Near Threatened” in the Red Data List.

Through education, research, influencing policy and partner working the IOSF is making progress but there is still much to be done here in the UK and other countries where otters are at risk.

Your support is greatly appreciated and the donations you make help secure a better future for otters in the UK and around the world.

We guarantee we will NEVER pass on your details to anyone else.
