Geometry Type: esriGeometryPolygon

Description: The EULACHON_VOL2 depicts known eulachon habitat areas in six environmentally sensitive areas along the Southeast coast of Alaska. This data was digitized from mylar original maps from the Alaska Habitat Management Guides (1986), and updated bluelines from area biologists (1997). Data for the following categories were captured: Known spawning concentration areas - areas where concentrations of spawning eulachon have been observed during more than one year. Data exists only for those 1:250000 quads that contain six specific sensitive areas identified as MESAs with eulachon data; data are not continuous along the coast. For a complete list of MESA areas with eulachon data please see the metadata section on data quality.
