National Fish Habitat Partnership (NFHP) 2015 Anthropogenic Disturbance Data for the Conterminous United States linked to the NHDPLUSV1

This CSV file contains landscape factors representing anthropogenic disturbances to stream habitats summarized within local and network stream catchments of Southeast Alaska. 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) b

National Fish Habitat Partnership (NFHP) 2015 Cumulative Habitat Condition Indices with Limiting and Severe Disturbances for the Conterminous United States linked to NHDPlusV1 v2.0

This CSV file contains cumulative fish habitat condition index (HCI) scores generated for river reaches of the conterminous United States as well as indices generated specifically for four spatial units including local and network catchments and 90 m local and network buffers of river reaches. Note that the cumulative HCI score is determined from limiting index scores generated for the four spatia

National Fish Habitat Partnership (NFHP) 90 Meter Buffers of the NHDPlusV1 for the Conterminous United States

This geodatabase contains 90 meter buffers of streams within the National Hydrography Dataset Plus Version 1 (NHDPlusV1). These buffers were developed by converting NHDPlusV1 flowlines to a 30m grid, then running a euclidean allocation function in ArcPy to generate buffer zones. For flowlines representing artificial paths within NHD area river polygons, buffers extend from the outside edges (banks

National Fish Habitat Partnership (NFHP) 2015 Cumulative Habitat Condition Scores and Disturbance Indices Linked to Catchments of Southeast Alaska

This shapefile contains cumulative fish habitat condition index (HCI) scores as well as specific disturbance indices for local and network catchments of Southeast Alaska. Catchments were created in support of Jared Ross's Masters thesis. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across th

National Fish Habitat Partnership (NFHP) 2015 Cumulative Habitat Condition Scores and Disturbance Indices for Hawaii Linked to Catchments of the Hawai'i Fish Habitat Partnership Stream Layer

This shapefile contains cumulative fish habitat condition index (HCI) scores and specific disturbance indices for local and network stream catchments as well as the downstream main channel catchment of perennial and intermittent streams reaches of the five main island of Hawaii. In this dataset indices are linked to the Hawaii Fish Habitat Partnership (HFHP) stream layer (Tingley et al. in prep) w

National Fish Habitat Partnership (NFHP) 2015 Human Disturbance Data for Hawaii

This CSV file contains landscape factors representing anthropogenic disturbances to stream habitats summarized within local and network stream catchments as well as the downstream main channel catchment perennial and intermittent stream reaches of the five main islands of Hawai'i. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fl

National Fish Habitat Partnership (NFHP) 2015 Human Disturbance Data for Alaska linked to HUC12 watersheds

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

GAP/LANDFIRE National Terrestrial Ecosystems 2011

The U.S. Geological Survey Gap Analysis Program (GAP) National Terrestrial Ecosystems - Ver 3.0 is a 2011 update of the National Gap Analysis Program Land Cover Data - Version 2.2 for the conterminous U.S. The GAP National Terrestrial Ecosystems - Version 3.0 represents a highly thematically detailed land cover map of the U.S. The map legend includes types described by NatureServe's Ecological Sys
