Proportion of annual area of potential nesting forest burned at three fire severities [unburned-low (UL), moderate (M), and high (H)] in three forest types [NON-NESTING (a), EDGE (b), and INTERIOR (c)]. Also are the linear trends in annual proportion of fires burning at high severity in NON-NESTING (d), EDGE (e), and INTERIOR (f) forest types. Data are from 472 large (≥200 ha) wildfires occurring throughout the range of the northern spotted owl, USA, 1987–2017. Potential nesting forests were those areas with environmental conditions of elevation (below 2000 m) and soil types that without disturbance could develop into suitable forest for nesting and roosting by spotted owls given time for succession
