salmonid ecological neighborhoods, Chehalis River basin (2017-2019)

Contents of this dataset were used to define contemporary neighborhood boundaries for three anadromous salmonid species across a complex river network in southwestern Washington State, USA. Extensive field surveys covering 669 river km across two years documented the upper limit of occurrence (ULO) for coho salmon (O. kisutch), steelhead trout (O. mykiss), and chum salmon (O. keta) as well as any local features, such as natural barriers, that influenced the ULOs. Generalized linear mixed models quantified the relationships between the ULOs and landscape attributes derived from remote sensing data. Included herein are the data and scripts used for this analysis.
