Managed by the Alderney Wildlife Trust, Longis covers approximately 105 hectares to the Northwest of the Island. It has 13 distinct habitats, including marine, coastal heathland woodland and freshwater ponds, both natural and man-made. The bird hides are an ideal place to watch and enjoy Alderney’s rich wildlife in a uniquely positioned and peaceful environment and it is known for its great diversity of plant species. The marine and freshwater wetlands within the reserve provide an important site for migratory birds with other habitats also hosting many of the island’s best mammal habitats. There are many numerous insect species, nearly 100 of national importance, many of which have not yet occurred in the UK.
