Become a Ranch Guide at ACR's Martin Griffin Preserve and share your knowledge and appreciation of nature with our Bay Area community during the awe-inspiring heron and egret nesting season. After training, Ranch Guides provide information to visitors about the preserve and its many unique natural features during the public season, which spans from mid-March through mid-July.

Learn about birding, biology, natural history & the environmental victory to save this preserve. Great for birders, nature enthusiasts, novices & experts alike!

As the Bay Area’s urban landscapes expand and sprawl, wild spaces where children and families once enjoyed and experienced nature have been decreasing and, in some cases, altogether disappeared.

Ranch Guide training begins in January 2012
