NV = night-viewing; HS = hand search; T = trapping; KS = kick-sampling; HR = historic records, P = Proxy measure e.g. otter spraints; p/a denotes presence absence data; CPUE denotes ‘catch per unit effort’, ‘?’ denotes information not stated, ‘·’ denotes variable measured ‘+’ and ‘−’, denote positive and negative, respectively statistical correlation between parameter and presence/abundance. The presence of both signs indicates different relationship for different parts of population, or different aspects of the parameter measured.
