CNPS teams with the Klamath National Forest to map yellow-cedar (Callitropsis nootkatensis) in California
CNPS has begun a collaborative mapping and inventorying project for yellow-cedar in California. The species is a CNPS Inventory of Rare and Endangered Plants on list 4.3 (limited distribution) in the state, with only a handful of known locations. The majority of the stands are on the Klamath National Forest but a few are also on the Six Rivers. Over the course of summer 2017, Michael Kauffmann and Julie Evens will be visiting a number of these populations and collecting data on stand health, reproduction, and plant associations. The week of July 5-6 we visited the world’s southern-most stand, deep in the Siskiyou Wilderness.
This project was initiated by Forest Service Region 5 when we were contacted by Brian Buma from University of Alaska. His research is showing that yellow-cedar at the northern extent of its range is in declining health and not reproducing. The baseline data we collect this summer will inform future studies across the range of this species.
