From: Post-fire movements of Pacific marten (Martes caurina) depend on the severity of landscape change

Fig. 2

Marten movements in response to canopy closure and burn severity on post-fire landscapes, based on linear and logistic regressions. Data are from north-central Washington, USA (2006 burn), and central British Columbia, Canada (2010 and 2017 burns). “Burn index” measures the average burn severity along a marten trail from 0 (entirely unburned) to 4 (entirely high severity).Trails with high directedness, at y = 1, differ significantly from the characteristics of a correlated random walk, and would be expected from marten moving through low-quality habitats. Dashed lines show sample means; asterisks denote statistical significance. Light gray dots are significant outliers excluded from regressions. X-axis labels apply to all columns
