Editing Transverse Ranges (section)

==Ecology==
[[File:North Slope Santa Ynez Mtns.jpg|thumb|Savannah-like oak woodlands are typical of the westernmost ranges; shown here is the north slope of the [[Santa Ynez Mountains]]]]
The plant place of the Transverse ranges include [[coastal sage scrub]], [[California oak woodland|oak woodland and savanna]], and [[pinyon-juniper woodland]] at lower elevations, and [[yellow pine forest]], [[Lodgepole Pine]], and [[subalpine forest]] at higher elevations.<ref>Schoenherr, Allan A. (1992). [[A Natural History of California]]. Berkeley, CA: University of California Press.</ref> The [[Angeles National Forest|Angeles]] and [[Los Padres National Forest]]s cover portions of the Transverse ranges. The ranges are part of the [[World Wildlife Fund|WWF]]-designated [[California montane chaparral and woodlands]] [[ecoregion]], but the eastern points of the range touch two desert regions, the Mojave Desert and the Colorado Desert section of the [[Sonoran Desert]]. The [[Carrizo Plain]] adjoins the northern edge of the Transverse Range.{{Citation needed|date=January 2021}}

Chaparral is a common feature of the Transverse Ranges. Common plant associates in [[chaparral]], especially in the transition between coastal chaparral and coastal sage scrub, include [[California sagebrush]] and [[Toyon]], the latter shrub having its southern distribution limit defined by the Transverse Ranges.<ref>[http://globaltwitcher.auderis.se/artspec_information.asp?thingid=84109&lang=us C.

Pinyon-juniper woodland is common on the north slopes of the San Gabriel and San Bernardino Mountains. This ecosystem is easily visible in the well-travelled [[Soledad Pass]] region, between [[Pearblossom, California|Pearblossom]] and [[Santa Clarita, California|Santa Clarita]].{{Citation needed|date=January 2021}}

===Urban impact===
A number of densely populated coastal plains and interior valleys lie between the mountain ranges, including the [[Oxnard Plain]] of coastal [[Ventura County]], the [[Santa Clarita Valley]] north of Los Angeles, the [[San Fernando Valley]], which is mostly included in the City of Los Angeles. The Los Angeles Basin, which includes the portion of [[Los Angeles County]] south of the Santa Monica Mountains and most of [[Orange County, California|Orange County]], and the [[Inland Empire (California)|Inland Empire]] basin, which includes the cities of [[San Bernardino, California|San Bernardino]] and [[Riverside, California|Riverside]], lie between the Transverse Ranges and the Peninsular Ranges to the south.{{Citation needed|date=January 2021}}
