HABITAT: Coastal Prairie

COASTAL PRAIRIE HABITAT

DESCRIPTION

Namesakes such as Prairie Avenue and Meadows School describe what was once the main habitat of Manhattan Beach east of the sand dunes to about the 405 freeway. Mounds of undulating evergreen grasses and patches of low shrubs covered the treeless landscape. Wildflowers of blue, yellow and white sprang forth from the greenery in spring, and numerous watery depressions called vernal pools dotted the landscape. One such pool is now a pond at Polliwog Park, and although greatly altered for flood control, remains a rare reminder of the past. The plants of the species-rich coastal prairie habitat are well adapted to the cooling effects of fog as well as rainy winters and long dry summers.

SOIL

Generally moist to semi-moist all winter and semidry to dry throughout summer and fall. Non-native grasses that make up a conventional lawn require fertilizers and year-round water to remain healthy. Well draining soil with no added fertilizers, but plenty of rain winter-spring and occasional irrigation summer-fall, will do in the home garden planted with local CA native bunch grasses, low shrubs, wildflowers and bulbs.

WHERE TO FIND IN NATURE LOCALLY

Coastal prairie habitat in critically endangered in California. In Los Angeles most has been lost to urbanization, however driving two hours north in spring, one can see an eye-popping array of native wildflowers, grasses and prairie wildlife at Carrizo Plain National Monument in southeastern San Luis Obispo County:

PRAIRIE GRASSLAND PLANT and WILDLIFE COMMUNITY

In addition to grass, wildflowers play a big role in this habitat. Yellow pincushions will draw an assortment of tiny bugs to the garden. They serve as mini-pollinators as well as a protein-rich snack for birds. Hummingbirds love Miniature Bicolor lupine of blue and white, which can still be found wild in sections of Polliwog Park. With white tipped petals, Tidy Tips, along with Goldfields are springtime garden beauties. Aphids will be quickly consumed by ladybug larva (photo below) as well as adults.
