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).
FISH_METHOD
(
type: esriFieldTypeString, alias: FISH_METHOD, length: 30
, Coded Values:
[Field Surveyed: Field Surveyed - The systematic observation, identification and collection of quantitative information describing fish or fish habitat, following a standardized methodology (Electrofishing, Spawning Surveys, eDNA, Snorkel, etc.).]
, [Professional Opinion/Modeled: Professional Opinion/Modeled - Professional Opinion: An opinion formulated by an individual biologist from a natural resource agency or tribe. Generally, this is Presence Not Verified (PNV). Modeled: A schematic description of a system, theory, or phenomenon that accounts for its known or inferred properties and may be used for further study of its characteristics (ex. LiDAR, Digital Elevation Models, Species Occupancy Model, etc.). Generally, this is Presence Not Verified (PNV).]
, [Other: Other - Alternate methods used that are not captured in the other methods. To be described in Comments field (ex. HydConversion). Generally, this is Presence Not Verified (PNV).]

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.
