Deer, Owls, Coyotes and Nature

Ecologically and physically, the Preserve is continuous with adjacent undeveloped lands conserved in upper San Juan Canyon. Deer and coyotes roam free without fences; deer are often seen. Hawks, owls and many other birds are frequently spotted; many bird species can nest in the Preserve’s habitats.

Sturdy trunks and long arching limbs of dense, mature coast live oak (Quercus agrifolia) shelter most of the Preserve. A grove of tall oaks below the homesite creates an open, airy forest with a grassy floor and an exceptionally high canopy.

Lower, wetter sections to the northwest host willow (Salix lasiolepis) riparian forest and groves of impressively gnarled buckeye trees (Aesculus californica). Beneath the tree canopy, grassland and herbaceous understory grow with some northern coastal scrub in open areas.

Wildflowers add bursts of color to the Preserve’s palette.
