The Greyhawk Preserve was established and protected with a Conservation Easement in 2001 to mitigate for loss of wetland habitat. The Center for Natural Lands Management (CNLM) holds the Conservation Easement on this Preserve, protecting approximately 31 acres in 4 lots within the Gladstone Park subdivision in Granite Bay, Placer County. The Gladstone Park development is a 71-lot residential subdivision that covers approximately 76 acres and was designed to minimize the impact to riparian and seasonal wetlands. CNLM monitors for easement and management plan compliance.

Conservation Significance

The Preserve protects oak woodlands, annual grassland, approximately 11 acres of riparian woodland/wetlands, and one acre of seasonal wetlands. Blue oaks (Quercus douglasii), interior live oaks (Quercus wislizeni), and California foothill pine (Pinus sabiniana) are common in the oak woodlands, in the riparian woodlands.

Our Work

The Home Owners Association (HOA) manages the Preserve. CNLM works with the Home Owners Association to protect and promote the Preserve’s conservation values, including oak woodland and wetlands.

Public Access

Due to the vulnerability of the species and habitats that exist on this Preserve, it is not open to the public.
