Editing Oak Park, California (section)

===Flora===
Oak Park ecosystems include several within the [[chaparral]] (inland [[Lamiaceae|sage]] scrub, rocklands, northern slope chaparral scrub, southern slope chaparral scrub) and [[riparian]] woodland ([[coast live oak]] riparian forest, [[valley oak]] woodland, southern willow scrub, [[Walnut tree|walnut]] stands, and oak [[savanna]]). Southern California grassland has largely disappeared from the site by overgrazing and housing.

The chaparral and grassland are frequently altered by fires started by natural causes and humans. Both Indians and ranchers have altered the local landscape through fire and grazing. Oak Park had a large uncontrolled fire on October 8, 1982. The most recent uncontrolled fire was the [[Woolsey Fire]] on November 8–9, 2018 that burned through Oak Park and surrounding areas.

The recorded flora during the last EIR of Oak Park included 202 vascular plant species distributed among 52 families. Half are found in 5 families: [[sunflower]](Asteraceace), grass (Poaceae), pea (Fabaceae), [[Mustard plant|Mustard]] (Brassicaceae) and figwort (Scrophulariaceae).

There are 4 plants classified as sensitive: Catalina Mariposa Lilly (Calochortus catalinae), [[Wind poppy]] (Stylomecon heterophylla), [[Santa Susana Mountains|Santa Susana]] Tarweed (Hemizonia minthornii ), and Nolina Parii
