Pet Policy
For the protection of wildlife and bird species that inhabit and nest in Sweet Springs, dogs and other pets are not encouraged, but are currently allowed. Pets must be kept on a 6-foot leash and stay on trail.

The MCAS Board recently voted that effective September 2017, pets will no longer be permitted on the Preserve. This change is necessary to limit disturbances and protect the birds and other wildlife within the Preserve. MCAS appreciates the cooperation of pet owners.

To better understand this new policy, MCAS is providing the following information:

History of the Sweet Springs Site - from ~500 AD to 2017
Archeological artifacts indicate the area where Sweet Springs is located was originally settled by the Chumash as early as 500 AD and they lived there through the late 1700s. The area was subsequently “discovered” by the Spaniard Captain Gaspar de Portola during the ‘Sacred Expedition,’ from Mexico through San Diego to Upper California, from 1769 to 1770.

East Sweet Springs 2017 Expansion Project
The Morro Coast Audubon Society acquired the 8.3 acre East parcel in 2008. In 2011 MCAS applied to the County of San Luis Obispo for a minor use permit (MUP) allowing for native plant restoration and public access project at East Sweet Springs. In 2017 the MUP was approved and now East Sweet Springs will be developed with boardwalks, signage, benches, viewing blind, and more. Together with West Sweet Springs and Central Sweet Springs, the Sweet Springs Nature Preserve will continue to be a place to walk, watch birds, and enjoy a quiet and peaceful natural environment.
