Clement famous that just a few privately owned inholdings stay on Mount Diablo, every below 100 acres.
“There are also other privately owned properties on the slopes of the mountain that are contiguous with state parks but not fully surrounded, and we are also trying to get those secured,” he stated.
Although solely 5 acres, the Nunn-Paulsen inholding is a “compact and biologically diverse gem,” with blue oak and reside oak woodland, and oak savanna habitat, stated Save Mount Diablo.

“But at the same point in time, he didn’t necessarily savor being called that. It was more as a point of action and conscience, versus trying to make people believe that was the impression that he wanted to move forward (with),” Nunn stated. “He did it because it was the right thing, not to gain attention.”
Nunn stated the household has been energetic in land stewardship for many years.
“For example, we sold the development rights, a long-term agricultural property to help the Brentwood agricultural land trust,” he stated. “My father previously dedicated a few acres to the East Contra Costa County Historical Society. … So it’s kind of a multi-generational mindset, conservation, and at times, donation and dedication, separate from any business relationships that we have.”
Nunn believes the household will proceed to take part in land dedications and donations sometimes.
“Don’t be surprised if you see something a bit larger that takes place next year again. I’ll probably do it as an honor to my father,” stated Nunn.
