Bigcone Douglas-Fir (Pseudotsuga macrocarpa) in the San Gabriel Mountains National Monument — Part two

The 346,177 acre San Gabriel Mountains National Monument was dedicated in October 2014 by a proclamation by President Obama after nearly 10 years of work to get it established.  It contains the Sheep Mountain Wilderness, the San Gabriel Wilderness, and Pleasant View Ridge Wilderness as well as most of the major peaks including Mount San Antonio, Mount Baden-Powell, and Throop Peak.

I’ve been contracted by the US Forest Service, in partnership with the California Native Plant Society, to map Bigcone Douglas-fir in the monument as well as write a technical report about our findings. We did initial reconnaissance last week and will return later this year to initiate the project’s data collection phase. What follows are images from our trip across the range to meet the species and the monument.

Bigcone Douglas-Fir (Pseudotsuga macrocarpa) in the San Gabriel Mountain National Monument — Part one

I have always wanted to visit the San Dimas Experimental Forest and as part of a mapping and monitoring project for bigcone Douglas-fir, I finally had the opportunity. The “forest” descriptor in the area’s title is a bit misleading, as the majority of the vegetation is chaparral–but there are trees and it was our mission to find them (or at least what remains). Six major fires have been documented here since 1914, with the most recent occurring about 10 years ago. These fire events, along with climate change, are rapidly reshaping the remaining stands of trees. What follows is a photographic journey into the front range foothills of the eastern San Gabriel Mountains.
