Provide artificial nesting sites for owls

A replicated study in boreal forests in Gansu, China (Fang 2005), found that boreal owls Aegolius funereus, but not Sichuan wood owls Strix uralensis (formerly S. davidi also known as Ural owls) used nest boxes provided in 2002-4. A total of 120 nest boxes were provided, 50 for boreal owls and 70 for Sichuan wood owls. No boreal owls used nest boxes in 2002, four bred in 2003 (fledging eight chicks from three nests) and six bred in 2004 (fledging eight chicks from four clutches). Several species of songbird also use boxes. Boxes were erected at least 3 m up on tree trunks, lined with grass and mosses and of the same design as used in Europe for Ural owls. From 2003, some were encased in bark to make them appear more natural.
