Terrestrial Resources
The Gaviota Coast's unique biological richness is produced
by overlapping ranges of northern and southern biota, supported
by a mosaic of varied habitats created by a complex geologic history.
The majestic south-facing slopes of the Santa Ynez Mountains pour
down about 400 feet above sea level to the beaches below.
These beaches are usually rocky and narrow except where dune systems
occur (such as at Coal Oil Point). At several locations,
the contact of freshwater streams and seawater forms estuaries
with salt marsh habitats such as at Devereux Slough. The
coastal terraces, plains, and foothills form a mosaic of grassland,
shrubland, and woodland.
Agricultural
and urban land uses combine along the relatively narrow strip
of gentle topography between the ocean bluffs and the steep
rocky outcrops of the Santa Ynez Mountains and account for an
appreciable amount of the land cover. Uncommon within the
grasslands of the coastal mesas are relict patches of Vernal
Pool communities and Native Grasslands. Above the coastal
plain and foothills, generally on steeper slopes, is Chaparral,
which varies considerably from site to site depending on topography,
soils, and disturbance history. At still higher elevations
in the Santa Ynez Mountains, i.e. along the crest where annual
rainfall averages over 40 inches, forest communities are present.
Many creeks flow southward down the steep slopes of the Santa
Ynez Mountains, typically cutting deep canyons where vegetation
development can be lush, with Riparian Woodlands of large sycamores,
willows, cottonwoods, alders and live oaks especially along
the perennial creeks.
Some of the land animals to be found along the Gaviota Coast
include mountain lions, black bears, golden eagles, southern
alligator lizards, burrowing owls (rare but regular winter visitors
to the grasslands), and California newts (found in the upper
reaches of drainages in the Santa Ynez Mountains). The
Gaviota Coast also supports such endangered land animals as
the extremely rare California Condor, the California Brown Pelican,
the Southwestern Pond Turtle, the California Least Tern, and
the California Red-legged Frog (an uncommon resident of south
coast streams).
These mountainous watersheds connect the land to the sea.
Consequently, the health of the marine ecosystem is inevitably
linked to the condition of the land and its human uses.
