This data set contains sensitive biological resource data for forage
fish in Puget Sound and Strait of Juan de Fuca, Washington. Vector
polygons in this data set represent herring spawning and pre-spawner
holding areas. Species-specific abundance, seasonality, status, life
history, and source information are stored in relational data tables
(described below) designed to be used in conjunction with this spatial
data layer. This data set comprises a portion of the Environmental
Sensitivity Index (ESI) data for Puget Sound and Strait of Juan de Fuca,
Washington. ESI data characterize the marine and coastal environments
and wildlife by their sensitivity to spilled oil. The ESI data include
information for three main components: shoreline habitats, sensitive
biological resources, and human-use resources. See also the FISHL (Fish
Lines) data layer, part of the larger Puget Sound and Strait of Juan de
Fuca ESI database, for additional fish information.
