Herreman, K., Cooper, A., Daniel, W.M., Ross, J., and Infante, D.M., 2017, National Fish Habitat Partnership (NFHP) 2015 Human Disturbance Data for Alaska linked to HUC12 Watersheds: U.S. Geological Survey data release,


This CSV file contains landscape factors representing anthropogenic disturbances to stream habitats summarized within 6th level Hydrologic Unit Code (HUC12) watersheds of the Watershed Boundary Dataset. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) broadly representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units. Variables summarized at the HUC12 scale include measures of anthropogenic land uses, population density, roads, dams, mines, culverts, 303d [...]

These data were collected for multiple purposes. First, they were gathered in support of conducting a condition assessment of fish habitat in fluvial waterbodies throughout the United States in support of the National Fish Habitat Partnership (NFHP). Second, these data were intended to be made available to NFHP as well as other users interested in acquiring consistently-organized information over larger regions. This work was supported by local, state, and federal partners of NFHP, including the U.S. Fish and Wildlife Service and the U.S. Geological Survey. Because the condition assessment was conducted over such a large geographic region, we adopted a landscape approach for assessment which assumed that anthropogenic disturbances as well as natural characteristics in the watersheds affect a given unit of habitat which in turn would affect fishes. It was necessary to use a landscape approach because local measures of habitat or biological indicators of habitat condition are only available at a very small percentage of locations around the country while landscape data are available for every location in the United States.
