NatureScot Commissioned Report 784: A survey of the mason bee Osmia uncinata in Caledonian pine woodlands and evaluation of its status in 2006-07
Osmia uncinata is a species associated with gaps and open edges in Caledonian pine woodland. This study aimed to survey potential habitats to better understand the bee’s status and range, and to undertake an experimental investigation of trap-nests as monitoring tools. Osmia uncinata was not confined to old-growth Caledonian pine woodland, but is extant in commercial plantations with suitable conditions. Although the bees did not use the trap-nests, the survey results confirmed the bees’ requirements of open areas for foraging.
