About the reserve
Longis is the largest terrestrial reserve within Alderney, covering approximately 1/8th of the island and containing 13 distinct habitats. These range from marine, inter-tidal and coastal heathland to scrub woodland and freshwater ponds. Longis is a wildlife refuge, home to over 100 species of national importance.
The Reserve was designated under a memorandum of understanding in 2003 between the Alderney Wildlife Trust (AWT), the States of Alderney and local landowners.
Walking through the reserve's coastal trails you may glimpse rare plant species such as Small Hare’s-ear, Sand Crocus, Bastard Toadflax and Orange Bird’s-foot, as well as the endemic Alderney Sea Lavender on the rocky shore and, during late May and June, enjoy sightings of the nationally rare Glanville Fritillary.
Two bird hides overlook the reserve’s freshwater ponds (Longis and Mannez ponds), offering unrivalled views of waterfowl, songbirds and migrants alike.
Longis is the centre of the Alderney conservation herd with over 20ha managed using a small herd of Guernsey cattle, which help to maintain the wildflower-rich grassland and support the range of species that depend on it.
