The mid-elevation type of forest ponderosa pine and mixed conifer used to have about 60 trees per acre in California about 150 years ago.
Now, a UC Davis and USDA study says California forests 165 to 170 trees per acre — and that may be a conservative estimate. “That’s about a 3- to-1 increase from what it used to be like historically,” UC Davis researcher and U.S. Forest Service research ecologist Malcolm North told GV Wire℠ from his home in Mammoth.
