Background: Yellow-cedar (Callitropsis nootkatensis) is an economically and culturally important tree of the North Pacific coastal rainforest, ranging from northern California through Southeast Alaska. The species has been in decline for many decades, particularly in the northern portion of its range (Southeast Alaska and coastal British Columbia), and is currently under consideration for listing as Threatened or Endangered. Previous work has delineated locations of yellow-cedar stands across the species range, and modeled geophysical features associated with presence of the tree.Purpose: The purpose of this project is to support refinement of a range-wide analysis of bioclimatic factors that support healthy vs. dying yellow-cedar stands, across the range of the species, to allow modeling of future habitat suitability with climate change.
