Description: FISH_ANADROMOUS_ARC: This feature class is used to determine whether a particular anadromous fish species is present in a stream, which can affect protection buffer widths in land management plans and activities. The data comes primarily from the National Hydro Dataset (NHD), and is from actual observations or from modeled fish presence. While each district carried out their determinations in various ways, generally verification means that the fish biologist or other trained specialist was able to see the fish at the stream. This data is a descendent of the Aquatic Resources Information Management System (ARIMS).
Description: FISH_RESIDENT_ARC: This feature class is used to determine whether a particular resident fish species is present in a stream, which can affect protection buffer widths in land management plans and activities. The data comes primarily from the Hydro Update Project, and is from actual observations or from modeled fish presence. While each district carried out their determinations in various ways, generally verification means that the fish biologist or other trained specialist was able to see the fish at the stream.
Description: FISH_RESIDENT_POLY: Water bodies under BLM management that contain Resident Fish – fish that do not migrate out to the ocean but remain in freshwater.
Description: FISH_NON_NATIVE_ARC: This feature class is used to determine whether a particular non-native fish species is present in a stream, which can affect protection buffer widths in land management plans and activities. The data comes primarily from the Hydro Update Project, and is from actual observations or from modeled fish presence. While each district carried out their determinations in various ways, generally verification means that the fish biologist or other trained specialist was able to see the fish at the stream.
