Many amenity-rich regions are experiencing rapid land-use change in the form of low-density residential development. This widespread land-use change, exurbanization, has profound implications for regional biological diversity and ecosystem function. In the United States, exurban land use occupies seven times more area than land with urban and suburban densities, and has increased at a rate of about 10 to 15% per year. Drivers of exurbanization include technological advancements and increases in tele-commuting, transportation and road-network improvements, and various push- (crime, crowding, poor education systems, etc.) and pull- (affordable or desirable housing, privacy, better schools, etc.) factors. The rapid...

The REA estimates the condition of 14.2 million acres of land in southern New Mexico. It is based on states described in “ecological site descriptions” (ESDs) and expert knowledge. ESDs have been developed by the Natural Resource Conservation Service, and they are a consistent, science and expert-based resource increasingly used by land managers. It focuses on public rangelands - grasslands, shrublands, and savannas - managed by the Bureau of Land Management, and includes some other lands as well. The REA compares current condition to the expected or “reference” condition, and summarizes the vegetation, ecological processes and restorative management options of these states. Depending on these management options...

Abstract: Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010–11. U.S. Geological Survey Fort Collins Science Center (FORT) scientists collected an assemblage of biotic, abiotic, and hydrologic data from Topock Marsh during the drawdown and immediately after, thus obtaining valuable information needed by FWS. Building upon that work,...

We performed plant removal (devegetation) experiments across a suite of ecologically diverse wetland settings (tidal salt marshes, river floodplain, rotational rice fields, and freshwater wetlands with permanent or seasonal flooding) to determine the extent to which the presence (or absence) of actively growing plants influences the activity of the Hg(II)-methylating microbial community and the availability of Hg(II) to those microbes. Vegetated control plots were paired with neighboring devegetated plots in which photosynthetic input was terminated 4–8 months prior to measurements, through clipping aboveground biomass, severing belowground connections, and shading the sediment surface to prevent regrowth. Across...

Solar development has the potential to have widespread impacts on the California desert. Thus, it is important to have as much information as possible regarding the impacts of facilities and related infrastructure on the natural ecosystem and surrounding desert communities, how current policies are influencing development, and how the federal process is working on evaluating solar development applications. This research is detailed in this website. "Renewable Energy in the California Desert: Mechanisms for Evaluating Solar Development on Public Lands" is the result of sixteen months of research conducted by ten graduate students from the University of Michigan School of Natural Resources and Environmen t through...

Chihuahuan Desert landscapes exemplify the ecological conditions, vulnerability, and management challenges in arid and semi-arid regions around the world. The goal of the Jornada Basin Long Term Ecological Research program (JRN LTER) established in 1982 is to understand and quantify the key factors and processes controlling ecosystem dynamics and patterns in Chihuahuan Desert landscapes. In collaboration with the Jornada Experimental Range (USDA ARS), studies initiated in 1915 have been incorporated into the JRN LTER program. Previous research focused on desertification, a state change from perennial grasslands to woody plant dominance that occurs globally. Based on findings from growing long-term databases, the...

This dataset is based on the output from a project funded by the California Landscape Conservation Cooperative: “Decision support for climate change adaptation and fire management strategies for at risk species in southern California”. The potential distribution of Ceanothus verrucosus was modeled using a MaxEnt species distribution model using recent and future climate data with presence records from the San Diego Natural History Museum. Species distributions were modeled only for the South Coast Ecoregion in California, USA as this is where management options and climate change adaptation possibilities are currently being examined for the species. Recent climate data were based on the Parameter-Elevation Regressions...

REAs synthesize the best available information about resource conditions and trends within an ecoregion. They highlight and map areas of high ecological value, including important wildlife habitats and corridors, and gauge their potential risks from climate change, wildfires, invasive species, energy development, and urban growth. REAs also map areas that have high energy development potential, and relatively low ecological value, which could be best-suited for siting future energy development. In addition, REAs establish landscape-scale baseline ecological data to gauge the effect and effectiveness of future management actions. The Sonoran Desert REA was initiated in July 2010. It has been completed and peer reviewed...

Information about the condition of the land and related natural resources is needed at many different scales to inform decision makers. The U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) gathers rangeland on-site data as part of the National Resources Inventory (NRI). This report focuses on information derived from NRI rangeland data collected on-site 2004 to 2011. The findings reported here focus on key issues in rangeland science, including rangeland health, non-native plant species, non-native and native invasive plant species, bare ground, inter-canopy gaps and soil surface aggregate stability. Future reports will provide monitoring results based on data collected at revisited...
