In the pinyon-juniper woodlands and
associated sagebrush ecosystems of Nevada, progressive increases in tree
densities and woody fuel loads are resulting in dramatic increases in fire
frequency, severity and size and in the degradation of sagebrush
ecosystems. We are developing a basic understanding of the causes and
effects of tree expansion and increasing tree densities on pinyon-juniper
woodlands and sagebrush ecosystems. This includes examining changes
occurring in stand densities and fuel loads as well as in fire frequency,
intensity and size accompanying woodland expansion. It also includes
evaluating the effects of fire on sagebrush communities, soil erosion, and
water quality. We are using research results to devise techniques for
restoring and maintaining sustainable sagebrush ecosystems and pinyon-juniper
woodlands. Techniques include the use of prescribed fire as a restoration
tool and seeding methods for restoring native communities. We have
established a collaborative, Joint Fire Science Program Demonstration Area
in central Nevada for illustrating the ecological response of watersheds
dominated by trees to prescribed fire and we hold annual field tours.
