Assembling data Many different human landscape factors were assembled and used to characterize condition of Alaska stream fish habitat (Table 3). Factors include: urban and agricultural land uses; density of point sources of pollution in catchments; measures of stream network fragmentation, including densities of dams and culverts; density of infrastructure (road length, pipelines, etc.) and locations of mines. The availability of some landscape factors varied between southeast Alaska and greater Alaska (see Table 3). Some important threats to fish and fish habitats could not be incorporated into the assessment due to data availability limitations (one example includes forest harvest information across the entire...

After acquiring data, variables were attributed to a stream coverage for use in assessment following Wang et al. (2011). The Hawaii Fish Habitat Partnership (HFHP) stream layer (Tingley et al. in prep) is a modified version of the 1:24,000 National Hydrography Dataset that consists of 11,436 intermittent and perennial stream reaches across the five largest Hawaiian Islands (Hawai’i, Maui, Moloka’i, O’ahu, Kaua’i). The HFHP stream layer distinguishes stream reaches as sections of streams occurring between confluences, headwaters and confluences, and confluences and pour points, following the definition of stream reaches in the contiguous United States. Each reach has an associated local catchment (watershed), upstream...

Wheat and corn are the two most commonly grown crops in Kansas and Oklahoma and zones with a high risk of habitat degradation in eastern Kansas and Oklahoma correspond to areas of these and other row crops. Texas grew 6.2 million acres of cotton in 2014-15 predominately in the panhandle region, which was projected to be at high risk of fish habitat deterioration. Nutrient runoff from crop fields from all southern plains states not only affects local streams but eventually ends up in estuaries and the Gulf of Mexico. This high-nutrient runoff contributes to a low oxygen dead zone which annually averages over 5,000 square miles in size in the northern Gulf of Mexico and causes fish kills.

Abstract (from http://www.tandfonline.com/doi/full/10.1080/03632415.2016.1210517): Improving quality and better availability of continuous stream temperature data allow natural resource managers, particularly in fisheries, to understand associations between different characteristics of stream thermal regimes and stream fishes. However, there is no convenient tool to efficiently characterize multiple metrics reflecting stream thermal regimes with the increasing amount of data from continuously recording data loggers. This article describes a software program packaged as a library in R to facilitate this process. With this freely available package, users will be able to quickly summarize metrics that describe five...

This map service contains summaries of habitat condition indices (HCI scores) from the National Fish Habitat Action Plan (NFHAP) 2010 National Assessments for 8 digit Hydrological Unit Codes (HUC8s) of the United States. Initial HCI scores were developed in three separate assessments (Conterminous U.S., Hawaii, and Alaska) due to differences in data availability across these regions. In the initial NFHAP 2010 Alaska assessment HCI values were attributed to HUC12s. For this reason, to summarize data into HUC8s for Alaska an area-weighted average was used (i.e. the cumulative HCI score assigned to each HUC12 within a HUC8 was weighted by reach area using the formula (H1*A1+H2*A2...+HX*AX)/(A1+A2...+AX) where H = HCI...

National Fish Habitat Partnership (NFHP) 2010 HCI Scores for the Conterminous United States - by EDU
This shapefile contains summaries of habitat condition indices (HCI scores) from the National Fish Habitat Action Plan (NFHAP) 2010 assessment for Ecological Drainage Units (EDUs) in the Conterminous United States. Initial HCI scores were developed using landscape factors representing human disturbances summarized to local and network catchments of river reaches throughout the Conterminous United States. Habitat condition scores were based on responsiveness of biological metrics to anthropogenic landscape disturbances throughout ecoregions. Separate scores were created by considering disturbances within local catchments, network catchments, and a cumulative score that accounted for the most limiting disturbance...
