Description
On December 2, 2025, Bob Nunn generously donated five gorgeous acres, (known as the “Nunn-Paulsen inholding”), surrounded on four sides by Mount Diablo State Park, to Save Mount Diablo in memory of his late father, Ron Nunn.
“On behalf of Save Mount Diablo, I thank Bob Nunn for his generous donation of the strategic Nunn-Paulsen property to our organization in honor of his father, Ron Nunn,” said Ted Clement, Save Mount Diablo’s Executive Director.
“This property is on the slopes of Mount Diablo, and is an inholding surrounded on all sides by Mount Diablo State Park.”

This Marsh Creek watershed location includes two ephemeral streams, harboring a huge variety of plant life on its steep, rocky slopes.
The property contains blue oak and live oak woodland and oak savanna habitat. California red-legged frog and Alameda whipsnake are special status species that are likely to be present on the property. They’re confirmed on the neighboring Three Springs property.
Plus, the serpentine rock on the Nunn-Paulsen land provides excellent growing conditions for rare plant species.
