This data set contains biological resource data for estuarine, benthic, and pelagic fish in Southeast Alaska. Vector polygons in this data set represent locations of fish concentration areas. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Southeast Alaska. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the FISHL (Fish Lines) and FISHPT (Fish Points) data layers, part of the larger Southeast Alaska ESI database, for additional fish information.

Cumulative frequency distribution model maps created through analysis of surveys using surface trawls, purse seines, and environmental variables for salmon species in the Fishery Management Plan for Pacific Salmon in the Exclusive Economic Zone Off Alaska.

These datasets include the components of and results from the Rarity and Climate Sensitivity Index (RCS) and occurrence records used to calculate the index for 29 stream fishes native to the Pacific Northwest (Washington, Idaho, Oregon) of the United States. The RCS is an index that ranks species’ intrinsic sensitivity to climate change based on their area of occurrence and climate niche breadth, the range of environmental conditions for a given species. The RCS uses point occurrences to calculate both metrics. We compiled point occurrences from a variety of sources. Final point occurrences were filtered for quality assurance and received expert review (details in occurrence dataset metadata). We calculated RCS metrics at two spatial grains: 1) Hydrologic Unit Code (HUC) level 12 watersheds and 2) 1 km buffered occurrence points and stream segment level. The area of occurrence for each species was calculated as the total watershed area of all HUC 12 watersheds containing any of the final set of occurrence points or the total area of 1 km buffer around the final set of occurrence points. We calculated climate niche breadth using two sets of environmental variables at both spatial grains, bioclimatic and stream level. Bioclimatic level was calculated by extracting annual mean precipitation, maximum temperature of the warmest month, and minimum temperature of the coldest month from the area of occurrence using the the Parameter-elevation Regressions on Independent Slopes Model (PRISM) dataset. Stream level was calculated by extracting mean August stream temperature, mean stream baseflow, and either predicted streamflow permanence probability or predicted streamflow permanence class from all streams within the watershed area of occurrence or the nearest stream to each point occurrence for the 1 km grain. Stream level data was extracted using compiled streamflow permanence, water temperature, and modeled streamflow data (Sando and Schultz, 2022). Climate niche breadth from both levels is calculated as the area-weighted standard deviation for each variable. The RCS is calculated from the scaled and combined species’ area of occurrence and climate niche breadth, such that an intrinsically sensitive species has a small area of occurrence and a narrow niche breadth.

This data set contains sensitive biological resource data for marine, estuarine, and anadromous fish species in Western Alaska. Vector polygons in this data set represent fish distribution. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer. This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Western Alaska. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the FISHL (Fish Lines) data layer, part of the larger Western Alaska ESI database, for additional anadromous fish information.

Throughout the Pacific Northwest, stream habitat degradation has been cited as a factor contributing to the decline and ESA listing of of Pacific Salmon. Thus, stream habitat restoration is a major component of recovery plans as a method to increase salmon population productivity. Over 10 years after the majority of salmon listings we now have many datasets available to evaluate salmon habitat restoration placement, including our restoration projects database (Pacific Northwest Salmon Habitat Project Database), habitat assessments, salmon recovery plans, and spatial habitat mapping. By creating data dictionaries and metrics to standardize and analyze currently available datasets (e.g., restoration data, recovery plans, monitoring data, population abundance data) evaluations can be made to determine whether the right types of habitat actions are going in where they are most valuable. Further, a quantitative framework can be developed to link habitat conditions to fish population condition through stream restoration actions. This information can them be provided to local groups and agencies involved in salmon recovery to help inform the adaptive management process.

This data set contains sensitive biological resource data for marine, estuarine, anadromous, and freshwater fish species in the Bristol Bay Subarea. The Subarea includes marine and coastal areas of Bristol Bay and part of the southern Alaska Peninsula.

In nearshore marine areas, critical habitat includes areas contiguous with the shoreline from the line of extreme high water out to a depth no greater than 30 meters relative to mean lower low water.See the final rule (70 FR 52630) for descriptions of areas excluded from this critical habitat designation. Military areas ineligible for designation (qualifying Integrated Natural Resource Management Plan) were not clipped out of the data. Excluded military areas (due to national security impacts) and Indian lands were not clipped out of the data.
