Nest-box occupancy data for flying squirrels

Data describes occupancy (1=precence, 0=absence) of flying squirrels in nest boxes. BCODE= name of nest box. ID = a unique combination of box name and census year. Ural owl and goshawk columns describe modelled predation risk from these predators at the nest box site, see article for methods. h1...h27 refer to different land use classes and their combinations as in Table 1 of the research article. _200m and _1km means area (square meters) of that habitat within 200 meters and 1km from nest box, respectively. s (for example h17_200ms) refers to standarized amount of that habitat, see methods.
