The Great Big Nature Survey is all about people and nature.

The Wildlife Trust of South and West Wales, and the other Wildlife Trusts across the UK, want to hear your opinions on some of the biggest questions surrounding nature and our role in caring for it.

Surveys should be carried out by professional ecologists, registered with IEEM. When surveys involve protected species, such as bats, great crested newts or dormice, the surveyor should hold a license from Natural Resources Wales.

With nearly 350,000 breeding pairs of Manx Shearwaters, over 40,000 Puffins, thousands of Guillemots, Razorbills and Kittiwakes and hundreds of Fulmars, Skomer is an internationally important seabird island.

It is located less than a mile off the beautiful Pembrokeshire coast making it a great place to visit for the day or stay overnight.

Please note, Puffins start arriving in mid-April. They are present from May-July. The first ones start leaving in mid-July and all Puffins are gone by the end of July. Please see our seasonal timeline below for what to see each month.

Skomer is an amazing island - but it couldn't run without our volunteers! We have short-term and long-term opportunities available, please see below for details.

We have lots of exciting events planned for 2026 - these will go on sale on Monday 8th December.
