Analyzing and providing ecological context for the inventory and monitoring program of the Spring Mountains National Recreation Area in southern Nevada's Humboldt-Toiyabe National Forest. This program monitors ecosystems, rare species, and Spring Mountains endemic species.Regeneration biology of blackbrush (Coleogyne ramosissima: Rosaceae).Creosote community expansion into semi-arid grasslands, including pollination and gene flow at the shrubland/grassland ecotone and use of prescribed fire as a management tool to slow shrub expansion and maintain healthy grasslands. The effects of climate change on geographic shifts among southwestern plant communities.
Ecotone shifts; climate change; monitoring rare species during times of climate change; plant reproductive biology and establishment ecology; inventory and monitoring systems.
Reproductive biology of Atriplex spp. Blackbrush reproduction and establishment. Floral biology of alpine meadow plants. Effects of VA mycorrhizae and biological soil crusts on growth of selected desert plant species.
Resource managers need sound data and information in order to manage rare species and maintain the biological and recreational resources for future generations. Plant communities are under pressure from invasives and increased fire frequency, particularly shrub communities in the Western US. Research information is required to restore and maintain these communities.
