An assessment of the effects of human-caused air pollution on resources within the interior Columbia River basin.

Publications Posted on: August 01, 2018
An assessment of existing and potential impacts to vegetation, aquatics, and visibility within the Columbia River basin due to air pollution was conducted as part of the Interior Columbia Basin Ecosystem Management Project. This assessment examined the current situation and potential trends due to pollutants such as ammonium, nitrogen oxides, sulfur oxides, particulates, carbon, and ozone.

The Cold Water Climate Shield: Prioritizing high-value aquatic resources

Science Spotlights Posted on: September 11, 2015
Native trout are culturally and ecologically important, but climate change is likely to shrink the cold-water environments they require. Much can be done to preserve these fish but efficient planning and targeting of conservation resources has been hindered by a lack of broad-scale datasets and precise information about which streams are most likely to support native trout populations later this century. The Climate Shield is a useful took for aquatic fisheries conservation planning.

Future of the Middle Rio Grande

Publications Posted on: August 06, 2010
Because decisions made today about the Middle Rio Grande will influence future conditions, symposium participants - the stakeholders - collaborated in a final session to plan improvements for the watershed and river corridor. The result included several action plans focusing on desired future conditions and actions to achieve them.

Native montane fishes of the Middle Rio Grande Ecosystem: Status, threats, and conservation

Publications Posted on: August 06, 2010
Between 1994 and 1997, research was conducted on three native, montane species of the Middle Rio Grande Ecosystem, in the Carson and Santa Fe national forests. The focus of study was on abiotic and biotic factors that affected status, distribution, biology and habitat of these species.

Use of saltcedar vegetation by landbirds migrating through the Bosque Del Apache National Wildlife Refuge

Publications Posted on: August 06, 2010
We compared diversity, abundance and energetic condition of migrant landbirds captured in four different vegetation types in the Bosque del Apache National Wildlife Refuge. We found lower species diversity among migrants caught in exotic saltcedar vegetation than in native willow or cottonwood. In general, Migrants were most abundant in agricultural edge and least abundant in cottonwood.

Arthropods of native and exotic vegetation and their association with willow flycatchers and Wilson's warblers

Publications Posted on: August 06, 2010
We compared abundance of migrating Willow Flycatchers and Wilson's Warblers to the abundance of arthropods in exotic and native vegetation at Bosque del Apache National Wildlife Refuge. We trapped arthropods using glue-boards in 1996 and 1997 in the same cottonwood, saltcedar, and willow habitats where we mist-netted birds during spring and fall migration. There were fewer arthropods, particularly flies, in saltcedar.

Riparian dependence, biogeographic status, and likelihood of endangerment in landbirds of the Southwest

Publications Posted on: August 06, 2010
Riparian habitats and wetlands represent less than 2 percent of the land area of the Southwest, but they support the highest density and abundance of plants and animals in that region (Dahms and Geils 1997).

Biological diversity in montane riparian ecosystems: The case of the Mexican spotted owl

Publications Posted on: August 06, 2010
Although usually considered to be a bird of old growth mixed conifer forests, the Mexican spotted owl historically occurred in a wide range of habitats from lowland cottonwood bosques to montane canyon systems.

Status and migration of the Southwestern willow flycatcher in New Mexico

Publications Posted on: August 06, 2010
In the Southwestern United States, recent degradation of riparian habitats has been linked to decline of the Southwestern subspecies of the Willow Flycatcher. During a 2-year banding effort, migration patterns and bird fat content were analyzed. Recommendations for managers, and outlines for conservation plans, are included.

Bird migration through Middle Rio Grande riparian forests, 1994 to 1997

Publications Posted on: August 06, 2010
Expanding human populations in the middle Rio Grande have increased demands on water, land, and other resources, potentially disrupting bird migration activities. From 1994 to 1997, a total of 26,350 birds of 157 species were banded and studied. Results include species composition, timing of migration, and habitat use. Recommendations for managers are included.
