From the Rio to the Sierra: An environmental history of the Middle Rio Grande Basin

Publications Posted on: June 22, 2020
Various human groups have greatly affected the processes and evolution of Middle Rio Grande Basin ecosystems, especially riparian zones, from A.D. 1540 to the present. Overgrazing, clear-cutting, irrigation farming, fire suppression, intensive hunting, and introduction of exotic plants have combined with droughts and floods to bring about environmental and associated cultural changes in the Basin.

The brown-headed cowbird and its riparian-dependent hosts in New Mexico

Publications Posted on: August 01, 2018
Numbers of brown-headed cowbirds ( Molothrus ater) are increasing in some regions of North America, while certain populations of long-distance, neotropical migratory songbirds (NTMs) are declining. In the Southwestern United States, several species of NTMs nest only in riparian habitats.

Stopover ecology of landbirds migrating along the middle Rio Grande in spring and fall

Publications Posted on: May 12, 2016
This research represents the first comprehensive summary of our study of stopover ecology of migratory landbirds in riparian habitats along the middle Rio Grande of central New Mexico. We report results from mist-netting operations conducted during spring and fall migration in 1994, 1995, and 1996. A total of 23,800 individuals of 146 species were captured during the study.

Riparian species reports

Documents and Media Posted on: February 11, 2016
Resource managers need tools that identify the likely future of riparian habitats under various climate and fire scenarios. These tools can help focus limited resources on the most critical needs for wildlife species and identify opportunities for promoting natural regeneration of riparian woodland and wetland habitats. These species vulnerability pamphlets summarize potential effects of fire and climate change on native and nonnative species residing within New Mexico riparian, wetland and associated upland habitats.

How removal of invasive trees affects nesting birds in riparian areas

Science Spotlights Posted on: August 24, 2015
In central New Mexico's Middle Rio Grande corridor, birds such as the blue grosbeak (Passerina caerulea), black-chinned hummingbird (Archilochus alexandri), and the endangered Southwestern willow flycatcher (Empidonax traillii extimus) nest in invasive exotic tree species. Researchers studied nesting success in areas dominated by native tree species such as willows, areas dominated by invasive species such as tamarisk, sites that burned, those not burned, and those where invasive species had been removed.

Climate change vulnerability of wildlife in Southwestern U.S. riparian habitats

Science Spotlights Posted on: April 28, 2015
Rocky Mountain Research Station scientists have developed a coupled approach that combines species distribution models, predictions for future fire regime, and climate change vulnerability assessments to estimate the interactive impacts of climate change and fire on species that reside within riparian habitats in the Southwest.

Nesting ecology and nest success of the Blue Grosbeak along two rivers in New Mexico

Publications Posted on: June 26, 2013
From 1997 through 2008, we studied the nesting habits and nest success of the Blue Grosbeak (Passerina cerulean) along the middle Gila River (1997-2001) and the middle Rio Grande (2000-2008) in New Mexico. A riparian forest of cottonwoods grows along both rivers.

Habitat use of the Rio Grande silvery minnow (Hybognathus amarus) during a long-term flood pulse in the Middle Rio Grande, New Mexico

Publications Posted on: February 29, 2012
The Middle Rio Grande (MRG) of New Mexico has been influenced by man for over 500 years. Native Americans began diverting water to irrigate agricultural crops in the floodplain in the 14th century. The Spanish followed and increased agricultural irrigation to over 125 000 acres. Frequent flooding of the MRG valley in the 19th century led to many engineering projects in the early 20th century to control flooding.

Belowground ecosystems [chapter 9]

Publications Posted on: September 19, 2011
The USDA Forest Service defined ecosystem management as "an ecological approach to achieve multiple-use management of national forests and grasslands by blending the needs of people and environmental values in such a way that national forests and grasslands represent diverse, healthy, productive, and sustainable ecosystems" (June 4, 1992, letter from Chief FS). This approach spans many different scales, both in time and space.

Fish fauna [chapter 8]

Publications Posted on: September 19, 2011
The Rio Grande was recently classified as one of the most endangered or imperiled rivers in North America (American Rivers 1993). Originating in southwestern Colorado, it passes through New Mexico and forms the international boundary between the United States (Texas) and Mexico.
