COMPTUEX/JTFEX COASTAL CONSISTENCY DETERMINATION 25 OCTOBER 2006may be having a deleterious effect on the population and which may not be sustainable. Thestocks of blue, fin, humpback, sei, and sperm whales in the waters off California are consideredstrategic (Barlow et al. 1997). In addition, the California/Oregon/Washington Stocks of theshort-finned pilot whale (Globicephala macrorhynchus) and sperm whale (Physetermacrocephalus) have been designated as strategic.PinnipedsThree species of pinnipeds occur in the SOCAL OPAREA. Only one of the species, theCalifornia sea lion (Zalophus californianus), is abundant in the Southern California Bight. Asmall rookery is located on Santa Barbara Island. Guadalupe Island, just south of the OPAREA,is a major haul-out site (DON 2005). Large colonies of California sea lions are found on SanNicolas and San Miguel Islands. The Guadalupe fur seal also is found in the SOCAL OPAREA.This species is listed as threatened under the ESA, and is considered to be depleted andstrategic under the MMPA.Two other species, the harbor seal (Phoca vitulina) and the northern elephant seal (Miroungaangustirostris), haul out regularly in small numbers and occasionally pup on SCI. The harborseal (Phoca vitulina) occupies haul-out sites on mainland beaches and all of the ChannelIslands, including Santa Barbara, Santa Catalina, and San Nicolas Islands (DON 2005). Smallcolonies of northern elephant seals (Mirounga angustirostris) breed and haul out on SantaBarbara Island with large colonies on San Nicolas and San Miguel Islands (DON 2005). Allthree species are more abundant on the Channel Islands north of the SOCAL OPAREA.In San Diego Bay, two pinniped species occur: California sea lion and the Pacific harbor seal(Phoca vitulina). These species are occasionally observed on the beaches of the coastalproperties of NBC and SSTC. In general the SSTC area is not an active marine mammal area.There is little information on marine mammal abundance and distribution in the SSTC, but itappears there is little marine mammal activity in this area.The overall abundance of pinnipeds increased rapidly on the Channel Islands between the endof commercial exploitation in the 1920s and the mid-1980s. The growth rates of populations ofsome species appear to have declined after the mid-1980s, and some survey data suggestedthat local populations of some species were declining. The declines may have been a result ofeither inter-species competition or population numbers having exceeded the carrying capacity ofthe environment (Stewart and Delong 1993; Hanan 1996). More recently, most populations areincreasing (Carretta et al. 2004) and, in some cases, such as the seals, have recently occupiednew rookeries and haul-out areas.PAGE 18
