Supplementary Material
Supporting material includes maps of habitat concentration areas and corridor networks for each
focal species in the Statewide (Fig. S1) and Columbia Plateau (Fig. S2) analyses; a composite
map of corridor networks used in the analysis (Fig. S3); a biplot showing the first two axes of a
principal components analysis of home range, adult mass, and dispersal distance for all focal
species used in this analysis (Fig. S4); a map of the overlap between habitat concentration areas
identified using the landscape integrity and focal species approaches (Fig. S5); results of the
analysis of spatial overlap between corridors identified using the landscape integrity and focal
species approaches compared to the amount of overlap expected by chance (Fig. S6); and the
performance of the landscape integrity approach at representing the full focal-species composite
corridor network (dotted horizontal line) for the Columbia Plateau ecoregion, compared to
increasing numbers of randomly selected focal species, using composite networks resampled to
450m resolution and 1800m resolution (Fig. S7).

Statewide analysis.

Columbia Plateau analysis.

Figure S3: Composited corridor maps used in the analysis. Maps were created by summing
standardized corridor scores for each focal species and landscape integrity sensitivity class (see
methods).

Figure S4: Biplot showing the first two axes of a principal components analysis of logtransformed maximum observed home range (in km2), adult mass (in grams), and maximum
observed natal dispersal distance (in km) for 22 focal species used in this analysis.

Figure S5: Overlap between habitat concentration areas (HCAs) identified using the landscape
integrity (LI) and focal species approaches.

Figure S6: Spatial overlap between corridors identified using the landscape integrity and focal
species approaches at two spatial scales, greater Washington State, and the Columbia Plateau
ecoregion, compared to the amount of overlap expected by chance (dotted line, see methods).
Percentile represents the area threshold used to convert the two composites to binary maps. For
example, overlap at the 80th percentile is the proportion of the landscape that is coincident when
the highest-value 20% of the landscape is compared between the landscape integrity and focal
species composites.
