Title

Effects of Timber Harvest on Big Huckleberry (Vaccinium membranaceum) Growth in the Umatilla National Forest

Abstract

Big huckleberry is native to the Umatilla National Forest and has a longstanding ethnobotanical history. Not only is it a charismatic shrub, drawing many to the forest every summer to collect its sweet berries, but it is also a culturally significant first food for the local Confederated Tribes of the Umatilla Indian Reservation. To evaluate how forest management has impacted huckleberry populations, I worked with the U.S. Forest Service during the summer of 2016 to evaluate huckleberry growth at nine sites differing in timber harvest severity and history. At each site I collected data on the density and size of huckleberry plants in both logged and control plots, and related the findings to patterns in insolation, ground cover, and other components of the vegetation. These findings will help the USFS better manage their logging operations in order to minimally disturb populations of the Umatilla big huckleberry.
