Description
The United States Geological Survey (USGS) Alaska Gap Analysis Project (GAP) compiles many smaller datasets of species occurrences to provide baseline information for conservation in Alaska, particularly when combined with other current efforts. These species occurrences (more than 1M occurrences for 300+ vertebrate species) were used with other ancillary data to generate distribution models and species range maps. The GAP models are among the first range-wide habitat models for vertebrate species at this resolution for Alaska. Prior to using Alaska GAP data, users are encouraged to become familiar with the GAP modeling process. These data provide researchers and managers with a tool for understanding the distribution of vertebrates within the context of these species habitats in Alaska.
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 1,193,488 records.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Study Area Description | The study area was the state of Alaska. Occurrence records were compiled from over 600 unique sources and were collected using diverse survey methods, study areas, and target taxa. Many wide-ranging taxa utilized habitats differently across their range, or elevation limits changed due to latitudinal differences over the study area. In an attempt to capture regional variation in habitat utilization, but not produce multiple models for a single taxon, Ecological Systems were filtered by physiographic region (including: Aleutian, Artic, Boreal, Sub-boreal, North American Pacific Maritime and Temperate Pacific) before the associated Ecological Systems were identified as suitable habitat or not for each taxon. |
Design Description | Because the dataset includes records from more than 600 sources, the design descriptions varied too widely to describe. |
