Grand Canyon River Alert System—Implementing an emergency alert system for wilderness recreation Grand Canyon River Alert System—Implementing an emergency alert system for wilderness recreation

The Grand Canyon River Alert System (GCRAS) provides government-issued emergency alerts to wilderness recreationalists in the Grand Canyon, who are often outside the bounds of cellular signal reception. GCRAS is a collaboration between the U.S. Geological Survey (Grand Canyon Monitoring and Research Center), National Weather Service, Coconino County Emergency Management, and National...

Mixed natal origins present management challenges for a non-native fish established throughout a modified river network Mixed natal origins present management challenges for a non-native fish established throughout a modified river network

Expansion of non-native brown trout (Salmo trutta) in the Colorado River below Glen Canyon Dam motivated reevaluation of suppression strategies to minimize potential impacts to native fishes in the Grand Canyon, Arizona, USA. Brown trout are one of several non-native fish species of management concern in this river reach, and understanding their natal sources and movement patterns may...

Canopy and surface fuels measurement using terrestrial lidar single-scan approach in the Mogollon highlands of Arizona Canopy and surface fuels measurement using terrestrial lidar single-scan approach in the Mogollon highlands of Arizona

BackgroundFuel monitoring data are essential to evaluate wildfire risk, plan management activities and evaluate fuel treatment effects. Terrestrial light detection and ranging (lidar) is a field-based 3D scanning technology with great potential to reduce labor-intensive field measurements and provide new depths of vegetation structure data.AimsTo facilitate the integration of terrestrial...

USGS Science Syntheses for Public Lands Management

Scientific information is fundamental to understanding how proposed actions on public lands may impact the environment. Development of new science is occurring at rates that can make it challenging for biologists, resource managers, decision makers, private landowners, and other stakeholders to ensure they are using up-to-date, high-quality science information to inform their decisions. Further...
