Transboundary Aquifer Assessment Program (TAAP)

Transboundary aquifers are an essential source of water for United States – Mexico border communities. Declining water levels, deteriorating water quality, and increasing use of groundwater resources on both sides of the border raise concerns about the long-term availability of this supply.

The U.S. – Mexico Transboundary Aquifer Assessment Act (Public Law 109-448) of 2006 was enacted...

USGS Data at Risk: Expanding Legacy Data Inventory and Preservation Strategies

As one of the largest and oldest science organizations in the world, USGS has produced more than a century of earth science data, much of which  is currently unavailable to the greater scientific community due to inaccessible or obsolescent media, formats, and technology. These “legacy data” are  invaluable for extending our historical understanding of the world’s natural resources,...

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Ciénega San Bernardino - Wetland Restoration

Desert marshes, or ciénega, are extremely biodiverse habitats imperiled by anthropogenic demands for water and changing climates. Given their widespread loss and increased recognition as important wildlife habitat, remarkably little is known about restoration techniques.

Patagonia - Gully Restoration

The Deep Dirt Farm Institute (DDFI), founded and directed by Kate Tirion, comprises 34 acres with deep agricultural soils, bisected by an ephemeral stream/wildlife corridor. The farm lies within a folded topography of hills, small sheltered valleys & broad meadow.  A deep gully has diverted flows and needs repair...

Nogales, Sonora - Flood Control

Flooding in Ambos Nogales often exceeds the capacity of the channel and adjacent land areas, endangering people and property. Goals of RDS are to diminish impacts of flooding and sedimentation on wastewater infrastructure thereby reducing the incidence of sanitary sewer overflows. We are studying the Nogales Wash to prevent future flood disasters and RDS are being installed in tributaries. We...

Process-based Approaches for Ecological Restoration of Degraded Drylands

Surface disturbances ranging from military training, recreation, energy exploration and development, and wildfires impact a large majority of federal lands in the western US, but the ecological and economic impacts are poorly understood. Explore this webpage to learn how Dr. Lesley DeFalco and her research team are currently evaluating and refining conventional approaches for post-fire...

Native Plant Materials for Ecological Restoration of Degraded Drylands

There is a growing consensus among resource managers to use native plant materials for ecological restoration of degraded drylands. Some plant species may be suitable for re-introduction across broad environmental gradients. Other species may fail under narrower conditions, or their re-introduction may have genetic consequences for local ecotypes, particularly when adapting to future climate...

Conservation of Rare, Sensitive, and At-risk Desert Plant Species

The Mojave Desert is among the hottest and driest of the North American drylands, but in spite of these extreme conditions, and in part because of them, a diverse flora exists. This diversity of rare, endemic, and endangered species is threatened by the complex interaction between fluctuating climate and human-mediated disturbances. USGS studies have identified rare species “hotspots” for...

Colorado Plateaus Regional Groundwater Availability

Pilot phase

This study is in a pilot phase during fiscal years 2017 and 2018. The purpose of the pilot phase is to identify possible technical challenges of using the USGS code GSFLOW for simulating groundwater and surface-water flow in the Colorado Plateau principal aquifer system. During the pilot phase, the project will evaluate GSFLOW in the San Juan River Basin (...
