On the north-west side of the island there is an area of maritime grassland with abundant thrift ( " Armeria maritima " ), sea beet ( " Beta vulgaris subsp . maritima " ) and tree mallow ( " Lavatera arborea " ).
Terns interchange regularly between all three sites, and form part of a larger Irish Sea tern population together with birds at sites in Ireland such as management measures they have undertaken here include control of introduced tree mallow ( " Lavatera arborea " ) and provision of nestboxes; these measures as aimed particularly at helping to increase the attractiveness of the site to breeding roseate terns, although it is accepted that the future number of pairs of this species here is primarily dependent on the overall health of the Irish Sea population.
