Maintaining and restoring sustainable ecosystems in southern Nevada [Chapter 7]

Publications Posted on: September 09, 2013
Managers in southern Nevada are challenged with determining appropriate goals and objectives and developing viable approaches for maintaining and restoring sustainable ecosystems in a time of rapid socio-ecological and environmental change. Sustainable or “healthy” ecosystems supply clean air, water and habitat for a diverse array of plants and animals.

Species of conservation concern and environmental stressors: Local regional and global effects [Chapter 6]

Publications Posted on: September 09, 2013
Species conservation has traditionally been based on individual species within the context of their requisite habitat, which is generally defined as the communities and ecosystems deemed necessary for their persistence. Conservation decisions are hampered by the fact that environmental stressors that potentially threaten the persistence of species can operate at organizational levels larger than the habitat or home range of a focal species.

Fire history, effects and management in southern Nevada [Chapter 5]

Publications Posted on: September 09, 2013
Fire can be both an ecosystem stressor (Chapter 2) and a critical ecosystem process, depending on when, where, and under what conditions it occurs on the southern Nevada landscape. Fire can also pose hazards to human life and property, particularly in the wildland/urban interface (WUI).

Invasive species in southern Nevada [Chapter 4]

Publications Posted on: September 09, 2013
Southern Nevada contains a wide range of topographies, elevations, and climatic zones emblematic of its position at the ecotone between the Mojave Desert, Great Basin, and Colorado Plateau ecoregions. These varied environmental conditions support a high degree of biological diversity (Chapter 1), but they also provide opportunities for a wide range of invasive species.

Water and water use in southern Nevada [Chapter 3]

Publications Posted on: September 09, 2013
Water and water use in southern Nevada is an important issue. The scarcity of water resources for both human and biologic communities often leads to intense competition for both surface and groundwaters. Anthropogenic and climate change impacts on scarce water resources need to be understood to assess human and ecosystem health for the study area.

Southern Nevada ecosystem stressors [Chapter 2]

Publications Posted on: September 09, 2013
Southern Nevada ecosystems and their associated resources are subject to a number of global and regional/local stressors that are affecting the sustainability of the region. Global stressors include elevated carbon dioxide (CO2) concentrations and associated changes in temperature and precipitation patterns and amounts, solar radiation, and nutrient cycles (Smith and others 2009b).

An overview of the Southern Nevada Agency Partnership Science and Research Synthesis [Chapter 1]

Publications Posted on: September 09, 2013
Southern Nevada is characterized by an arid to semi-arid environment with numerous cultural resources and a high level of biological diversity. Since 1980, the human population of the region has increased at unprecedented rates largely due to the expansion of suburban areas (Hughson 2009).

The Southern Nevada Agency Partnership Science and Research Synthesis: Science to support land management in Southern Nevada - Executive Summary

Publications Posted on: July 29, 2013
This synthesis provides information related to the Southern Nevada Agency Partnership (SNAP) Science and Research Strategy Goal 1 - to restore, sustain and enhance southern Nevada’s ecosystems - and Goal 2 - to provide for responsible use of southern Nevada’s lands in a manner that preserves heritage resources and promotes an understanding of human interaction with the landscape.

This synthesis provides information related to the Southern Nevada Agency Partnership (SNAP) Science and Research Strategy Goal 1 - to restore, sustain and enhance southern Nevada’s ecosystems - and Goal 2 - to provide for responsible use of southern Nevada’s lands in a manner that preserves heritage resources and promotes an understanding of human interaction with the landscape.

Is Pyrenophora semeniperda the cause of downy brome (Bromus tectorum) die-offs?

Publications Posted on: June 26, 2013
Downy brome (cheatgrass) is a highly successful, exotic, winter annual invader in semi-arid western North America, forming near-monocultures across many landscapes. A frequent but poorly understood phenomenon in these heavily invaded areas is periodic 'die-off' or complete stand failure. The fungal pathogen Pyrenophora semeniperda is abundant in cheatgrass seed banks and causes high mortality.
