Protected Areas and Ecological Reserves

Sylvan Meadows Multi-Use Area

Sylvan Meadows Multi-Use Trails are open 7 am - 4:30 pm daily - click here for trail map

The Reserve side is currently closed. Hiking, walking dogs on 6-foot leashes, horseback riding and mountain biking are permitted (sorry, no motorcycles or e-bikes). 

Fees are paid in exact cash only:  $4 adult, $3 child, $1 dog on 6' leash, or horse.

Annual passes available through RivCoParks and SRPNEF are sold online, valid for 12 months, and require an ID. We continue to seek volunteers to help at this site, read more.

Nearly 1,000 acres, and 10 miles of trails, can be enjoyed on the Sylvan Meadows Multi-Use Area.  Hikers, bikers and equestrians can experience trails of easy to moderate difficulty through a diverse array of habitats. From an historic dirt road from the Plateau’s ranching past, to single-track trails, Sylvan Meadows can be enjoyed by beginning and experienced hikers and bikers alike.

Trails travel through shady oak woodland, open bunchgrass prairie, and the state’s most common habitat of chaparral. Occasional bridges span riparian wetlands that often flow with streams during winter and spring months. One of the Plateau’s densest stands of rare Engelmann oaks can be found on a loop trail near the parking area, while the higher elevation of the Manzanita Trail provides distant views of the  Multi-Use Area and adjacent Ecological Reserve.

The Santa Rosa Plateau Ecological Reserve is adjacent to the Sylvan Meadows Multi-Use Area, and protects six distinct plant communities

Oak Woodland

Coast live oak woodlands frequent low lying areas. Engelmann oak savanna can be found on elevated land where water is infrequent, as Engelmann oaks are drought deciduous. Bird species such as band-tailed pigeons, acorn woodpeckers, red-shouldered hawks, screech owls, and great horned owls utilize these two oak species.


The native bunchgrass prairie on the Santa Rosa Plateau is considered the finest example of native grasslands remaining in California. The prairie reveals a host of native wildflowers — among them chocolate lilies, mariposa lilies, lupines, checkerblooms, shooting stars, and Johnny jump-ups. The grasslands are used by badger, mule deer, and many burrowing rodents.

Vernal Pools

Vernal pools are found on mesa tops, and support some of the rarest plant and animal species in the region – California Orcutt grass, San Diego button-celery, thread-leaf brodiaea, and fairy shrimp. During the winter months, these seasonal pools are frequented by many water fowl, including green-winged teals, Canada geese, grebes, greater yellowlegs, and long-billed dowitchers. As the water recedes in spring, brightly-colored wildflowers such as yellow goldfields and purple downingia circle the banks of the pools with bright color.


The most common plant community in California can be found on the Plateau in areas of granite rock outcroppings. Plant species such as chamise ceonothus and manzanita are characterized by their tough, woody stems and small leaves which help conserve water.

Coastal Sage Scrub

Gone frome 95% of its former sourthern California range, the Reserve protects examles of a plant community that is home to endangered species such as San Diego coast horned lizard and California gnatcatcher.

Riparian Wetland

Low-lying areas where gravity accumulates water support dense stands of vegetation including western sycamore, arroyo willow and poison oak. Pools along these stream coarses called tenajas (ten-ah-has) allow western pond turtles, California newts and red-legged frogs to survive through dry summer months.
