2007 Federal Recovery Outline for the Distinct Population Segment of South-Central California Coast Steelhead

摘要

The South-Central California Coast Steelhead DPS extends from the Pajaro River south to (but excluding) the Santa Maria River and includes those portions of coastal watersheds which are at least seasonally accessible to steelhead entering from the ocean. The topography of the area is dominated in the north by the southern end of the Santa Cruz Mountains, along the coast by the Santa Lucia Mountains, and in the inland areas by the Diablo, Gabilan, and Cholame/Temblor Mountains. The South-Central California Coast Steelhead Recovery Planning Area is encompassed by the Californian floristic province (Barbour et a1. 2007; Munz 1974; California Department of Fish and Game 2003). The watersheds within this province fall within two basic groups: those characterized by short coastal streams draining the several coastal mountain ranges (e.g., Santa Lucia Mountains), and those containing larger river systems (e.g., Pajaro, Salinas, Nacimiento, and San Antonio Rivers) that extend inland through gaps in the coastal ranges (Holland 2001; Jacobs 1993; Kreissman 1991).
