COMMISSIONED REPORT Summary Site condition monitoring for otters (Lutra lutra) in 2011-12 Commissioned Report No. 521 Project No: 12557 and 13572 Contractor: Findlay Ecology Services Ltd. Year of publication: 2015 Keywords Otter; Lutra lutra; monitoring; Special Area of Conservation. Background 44 Special Areas of Conservation (SACs) for which otter is a qualifying interest were surveyed during 2011 and 2012 to collect evidence to inform an assessment of the condition of each SAC. 73 sites outside the protected areas network were also surveyed. The combined data were used to look for trends in the recorded otter population in Scotland since the first survey of 1977-79. Using new thresholds for levels of occupancy, and other targets agreed with SNH for the current report, the authors assessed 34 SACs as being in favourable condition, and 10 sites were assessed to be in unfavourable condition.
