University of California Riverside’s Center for Conservation Biology will create a sustainable resource monitoring framework that will provide empirical data identifying if and how climate change is changing the composition and vitality of Joshua Tree National Park. These data will then help focus the Park’s resource management programs to help ensure the Park’s rich biodiversity can be sustained to the extent possible. A broader goal is to have this framework adopted across the surrounding public lands to then integrate data from multiple sites and land management philosophies to create an unambiguous picture of the impacts of climate change across the desert region.
Overview: This project represented a partnership between US Geological Survey (USGS) National Geospatial Program, the US Fish and Wildlife Service (on behalf of the Desert Landscape Conservation Cooperative (DLCC)), and the Center for Geographical Studies (CGS) at California State University, Northridge (CSUN). The project focused on updates and improvements to the high resolution National Hydrography Dataset (NHD) through the addition and/or improvement of NHD polygon, line, and point features in effort to fully realize a more robust and accurate NHD for priority areas within the DLCC geography. The work performed was designed to support the science objectives for the DLCC and its partners through the use of an...

Description: Invasive saltcedar is the third most abundant tree in Southwestern riparian systems. Resource managers must often balance the goals of protecting native wildlife species and habitats with the control of non-native and invasive plants. This project examined the impact of the tamarisk leaf beetle (a biocontrol agent) on amphibian and reptile (herpetofauna) and bird populations and communities along the Virgin River in Utah, Arizona and Nevada.Building on two years of pre-biocontrol monitoring, the researchers tracked changes in herpetofauna communities as the biocontrol entered a system dominated by a non-native plant species. The tamarisk leaf beetle is known to be eaten by several wildlife species....

Final Report WaterSMART Agreement No. R13AP80033Introduction: Sky Island Alliance is a non‐governmental organization that works to protect and restore the rich natural heritage of native species and habitats in the Sky Island Region. We work with volunteers, scientists, land‐owners, public officials, and government agencies to establish protected areas, restore healthy landscapes, and promote public appreciation of the region’s unique biological diversity.Springs are keystone ecosystems in the Sky Island Region, exert disproportionate influence on surrounding landscapes, and are known to be biodiversity hotspots. Although they are abundant in this arid region, they are poorly documented and little studied. Changing...

Prymnesium parvum (golden alga, GA) is a toxigenic harmful alga native to marine ecosystems that has also affected brackish inland waters. The first toxic bloom of GA in the western hemisphere occurred in the Pecos River, one of the saltiest rivers in North America. Environmental factors (water quality) associated with GA occurrence in this basin, however, have not been examined. Water quality and GA presence and abundance were determined at eight sites in the Pecos River basin with or without prior history of toxic blooms. Sampling was conducted monthly from January 2012 to July 2013. Specific conductance (salinity) varied spatiotemporally between 4408 and 73,786 mS/cm. Results of graphical, principal component...
