Provide artificial nesting sites for ground and tree-nesting seabirds
A before-and-after trial in northeast England (Morrison & Gurney 2007) found that the number of roseate terns Sterna dougallii at an island site increased following the creation in 2000 of an artificial nesting terrace and the provision of additional nest boxes (94 pairs in 2006 vs. an average of approximately 28 pairs in 1975–1999). Since 2003, all breeding pairs have used nest boxes. Before 2000 there were up to 12 nest boxes on the island, but 25 were installed in 2000 and more added each year until 200 boxes were present in 2006. Boxes were 15 x 30 x 45 cm with a 15 cm doorway; the terrace was 25 m long originally (it was extended in 2001), with three tiers, each protected by flagstones to prevent burrowing birds undermining its structure.
