[4] "Hummingbirds, hawks, northern mockingbirds and blue scrub-jays flock to Kenneth Hahn State Recreation Area," and the park is a nexus for the Black Birders movement.

[11] The Baldwin Hills area is the nesting grounds for 41 species of birds, and the Audubon Society offers monthly birdwatching walks.

[12] The park is immediately adjacent to the 1,000-acre (4.0 km2) Inglewood Oil Field, which, when combined with the parkland, provides an unusually large habit range for Los Angeles urban wildlife.

[14] The park's native habitat is the Coastal sage scrub plant community, with oak woodlands in northern arroyos and bunch grass grasslands on the southwestern windy and exposed terrain.

Invasive species in the park include black mustard, castor bean, milk thistle, agave, ice plant, nasturtium, and lantana.

[4] "The native plant community has been greatly altered by the hand of man, so much so that botanists describe Baldwin Hills flora as being in a condition called disclimax," reported the L.A. Times in 1988.

[15] The Olympic Forest includes "sea hibiscus from Seychelles, oleander from Algeria, sweet bay from Greece, Cajeput from Papua New Guinea…the paper mulberry from Toga, the carob from Cyprus, the date palm from Egypt.

[17] As Los Angeles quickly grew during the 20th century, only the rugged terrain of this section of the Baldwin Hills protected it from being developed.

"[4] The bowl of the reservoir (now called Janice's Green Valley) has been planted with grass and trees but remains visible and is the site of a popular jogging track.

An abandoned oil well at the top of the hill was decorated with sparkle lights during the holiday season and looked like a giant Christmas tree at night.

[22] The park, which is part of the greater Ballona Creek watershed, is now connected to nearby open spaces across La Cienega Blvd.
