Mammal inventories for eight National Parks in the Southern Colorado Plateau Network Mammal inventories for eight National Parks in the Southern Colorado Plateau Network
Historically, the Colorado Plateau has been the subject of many geological and biological explorations. J. W. Powell explored and mapped the canyon country of the Colorado River in 1869 (Powell 1961). C. H. Merriam, V. Bailey, M. Cary, and other employees of the Bureau of Biological Survey conducted biological explorations of the area in the late 1800s. In recent times, researchers such...

Climate matching as a tool for predicting potential North American spread of Brown Treesnakes Climate matching as a tool for predicting potential North American spread of Brown Treesnakes
Climate matching identifies extralimital destinations that could be colonized by a potential invasive species on the basis of similarity to climates found in the species’ native range. Climate is a proxy for the factors that determine whether a population will reproduce enough to offset mortality. Previous climate matching models (e.g., Genetic Algorithm for Rule-set Prediction [GARP])...

Applying radar technology to migratory bird conservation and management: Strengthening and expanding a collaborative Applying radar technology to migratory bird conservation and management: Strengthening and expanding a collaborative
Executive Summary Understanding the factors affecting migratory bird and bat populations during all three phases of their life cycle—breeding, nonbreeding, and migration—is critical to species conservation planning. This includes the need for information about these species’ responses to natural challenges, as well as information about the effects of human activities and structures...

Visitor and community survey results for Prime Hook National Wildlife Refuge: Completion report Visitor and community survey results for Prime Hook National Wildlife Refuge: Completion report
This study was commissioned by the Northeast Region of the U.S. Fish and Wildlife Service (USFWS) in support of the Comprehensive Conservation Planning at Prime Hook National Wildlife Refuge (Prime Hook NWR or Refuge). The National Wildlife Refuge Improvement Act of 1997 (Public Law 105-57, USC668dd) mandates a Comprehensive Conservation Plan (CCP) for every refuge in the system. A...

Simulation of flow and habitat conditions under ice, Cache la Poudre River - January 2006 Simulation of flow and habitat conditions under ice, Cache la Poudre River - January 2006
The U.S. Forest Service authorizes the occupancy and use of Forest Service lands by various projects, including water storage facilities, under the Federal Land Policy and Management Act. Federal Land Policy and Management Act permits can be renewed at the end of their term. The U.S. Forest Service analyzes the environmental effects for the initial issuance or renewal of a permit and the...

Interactions across spatial scales among forest dieback, fire, and erosion in northern New Mexico landscapes Interactions across spatial scales among forest dieback, fire, and erosion in northern New Mexico landscapes
Ecosystem patterns and disturbance processes at one spatial scale often interact with processes at another scale, and the result of such cross-scale interactions can be nonlinear dynamics with thresholds. Examples of cross-scale pattern-process relationships and interactions among forest dieback, fire, and erosion are illustrated from northern New Mexico (USA) landscapes, where long-term...

Increase in nuisance blooms and geographic expansion of the freshwater diatom Didymosphenia geminata Increase in nuisance blooms and geographic expansion of the freshwater diatom Didymosphenia geminata
The diatom Didymosphenia geminata (Lyngbye) Schmidt is emerging as an organism with an extraordinary capacity to impact stream ecosystems on a global scale. In recent years, streams in New Zealand, North America, Europe, and Asia have been colonized by unprecedented masses of “didymo” and its extracellular stalks (fig. 1). This diatom is able to dominate stream surfaces by covering up to...

Environmental effects of off-highway vehicles on Bureau of Land Management lands: A literature synthesis, annotated bibliographies, extensive bibliographies, and internet resources Environmental effects of off-highway vehicles on Bureau of Land Management lands: A literature synthesis, annotated bibliographies, extensive bibliographies, and internet resources
This report and its associated appendixes compile and synthesize the results of a comprehensive literature and Internet search conducted in May 2006. The literature search was undertaken to uncover information regarding the effects of off-highway vehicle (OHV) use on land health, or “natural resource attributes,” and included databases archiving information from before OHVs came into...
