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...

ABSTRACT: The Lower Colorado River and Rio Grande Basins are home to many riparian vertebrate species with different degrees of rarity. In our study, we focused on two species of birds and two species of gartersnakes that are associated with riparian areas: the Yellow-breasted Chat (Icteria virens), the Yellow Warbler (Setophaga petechia), the Northern Mexican Gartersnake (Thamnophis eques megalops) and the Narrow-headed Gartersnake (T. rufipunctatus). While the extent of distributions of these species is relatively large, they are often patchily distributed in populations that are small; in addition, both gartersnake species are listed as threatened under the Endangered Species Act. Aside from detrimental effects...

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....

Executive Summary: Our project combined field surveys of fish communities and habitat characteristics with estimates of population genetic structure to identify and evaluate critical factors influencing fish communities in the Gila River basin of New Mexico. Fish communities were structured along a strong habitat gradient associated with stream size, with distinct differences in the distribution of native and nonnative fishes. Nonnative warm-water species generally occurred in mainstem habitats, whereas coldwater nonnative salmonids occurred in high elevation tributaries. Habitat affinities of native species varied, with some occurring in mainstem habitats and others in tributaries. Several native species, such...
