Fig. 2From: Quantifying suitable late summer brood habitats for willow ptarmigan in NorwayExample area with transect-lines observations and random locations. To the left: Transect-lines placed in the landscape. On the right; a is a transect-line with all observations from 2014 to 2017, b the transect-line and observations with a 200-m buffer. Observations outside the 200-m buffer and observations with > 30-m deviation between reported and estimated perpendicular distance were excluded from analyses (see “Methods”). c Randomly generated available locations within the 200-m buffer, d available locations after adjusting for detection probability (see “Methods”) and e is willow ptarmigan locations and adjusted available locations used in the modellingBack to article page
