Maps of forests that are suitable for nesting and roosting by northern spotted owls. Map a: high-resolution aerial imagery of an area with clear-cuts, younger forest, closed-canopy old forest, and thinned old forest. Map b: the same area with an example binary map identifying nesting forest and non-nesting forest. Map c: same area showing nesting forest classified as edge and interior pixels
