This data set contains sensitive biological resource data for anadromous and threatened/endangered stream species in Northern California. Vector lines in this data set represent trout and salmon spawning runs and sensitive stream species. 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 Northern California. 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 FISH (Fish Polygons) data layer, part of the larger Northern California ESI database, for additional fish information.
