Abstract: Pinon-juniper vegetation covers some 100 million acres in the western U.S. where it provides economic products, ecosystem services, biodiversity, and aesthetic beauty in some of the most scenic landscapes of North America. There are concerns, however, that the ecological dynamics of pinon-juniper woodlands have changed since Euro-American settlement, that trees are growing unnaturally dense, and that woodlands are encroaching into former grasslands and shrublands. Yet surprisingly little research has been conducted on historical conditions and ecological processes in pinon-juniper vegetation, and the research that does exist demonstrates that pinon-juniper structure, composition, and disturbance regimes were very diverse historically as well as today. The purpose of this report is to briefly summarize our current understanding of historical stand structures, disturbance regimes, and landscape dynamics in pinon-juniper vegetation throughout the western U.S. The authors gathered for a workshop in Boulder, CO, on August 22-24, 2006, to develop the information presented here.
