Alderney's Ramsar (Convention on the Protection of Internationally Important Wetlands) site was the first to be designated in the Bailiwick of Guernsey. The site contains a mixture of habitats ranging from coastal grassland, shingle shorelines, rocky intertidal to sub-tidal kelp forests.

To maintain the designation the Trust undertakes a series of ecological studies including:

• Puffin research and management
   
• Storm petrel breeding
   
• Establishing new nesting sites for storm petrels
   
• Shag and Cormorant breeding
   
• Visitor management and awareness
   
• Tern census and breeding
   
• Ringed plover census and breeding
   
• Determine adult gannet population
