Description: The HERRING_VOL2 depicts polygon data for known Pacific herring habitat areas in six environmentally sensitive areas along the Southwestern, Southcentral and Southeast coast of Alaska. This data was digitized from mylar original maps from the Alaska Habitat Management Guides (1985 & 1986), special areas management plans and updated bluelines from area biologists (1997 and 1999). Data for the following categories were captured: For Southwest and Southcentral: Known spawning concentration areas - areas where the presence of spawning Pacific herring or herring roe-on-substrate have been observed. For Southeast: Known spawning concentration areas - areas where concentrations of spawning herring have been observed since 1974. Known wintering concentration areas - areas where concentrations of herring have been observed throughout the winter during more than one year. Herring line data for six other MESAs are contained in the coverage HERR_LNVOL2 in the EMCON directory which is part of the MESA data set. Data in this coverage exists only for those 1:250000 quads that contain six specific sensitive areas identified as MESAs with herring polygon data; data are not continuous along the coast. For a complete list of these six MESA areas please see the metadata section on data quality.
