Pinyon jays: Orchardists of the Great Basin’s woodlands

Science Spotlights Posted on: August 01, 2016
Over the past century, many pinyon-juniper woodlands in the Great Basin have expanded their range and increased their stand densities. These changes in structure and extent have effects on both the species that use the woodlands and to species whose habitat is being encroached by them. We observed and described where pinyon jays prefer to cache seeds in order to gain an understanding on how and where expansion and infill is likely to occur and to what extent jays are facilitating these processes.

Ecosystem consequences of regional pinyon mortality

Pinyon-juniper (Pinus edulis - Juniperus spp.) woodlands in the American Southwest have expanded in many areas since the late Nineteenth century. Woodland expansion has occurred in both, extent and increasing stand density. Expansion of woodlands has been attributed to reduced fire frequency, increased ungulate grazing, and changes in climate.
