Todd Chaudhry, Ph.D.

Todd is the Senior Science Advisor of the Northeast Region

I draw on my diverse experience as an ecologist and natural resource manager to facilitate interdisciplinary collaborations between USGS scientists and decision makers.  I coordinate applied research and monitoring in priority ecosystems across the Northeast and beyond, advancing our understanding of natural systems and supporting parters in achieving goals for clean lands and waters, healthy fish and wildlife, and resilient communities.  My approach is rooted in systems thinking, sound science, strong partnerships, and adaptive management focused on protecting the places that matter to the people we serve.

Case studies of riparian and watershed restoration in the southwestern United States—Principles, challenges, and successes Case studies of riparian and watershed restoration in the southwestern United States—Principles, challenges, and successes

Globally, rivers and streams are highly altered by impoundments, diversions, and stream channelization associated with agricultural and water delivery needs. Climate change imposes additional challenges by further reducing discharge, introducing variability in seasonal precipitation patterns, and increasing temperatures. Collectively, these changes in a river or stream’s annual hydrology...

Proceedings of the 12th Biennial Conference of research on the Colorado Plateau Proceedings of the 12th Biennial Conference of research on the Colorado Plateau

Introduction The Colorado Plateau is a physiographic region that encompasses 330,000 square kilometers in parts of four states in the southwestern United States (Colorado, Utah, New Mexico, and Arizona). Known for its high deserts, the Colorado Plateau also includes isolated mountains, high plateaus, and rugged canyons. Not only is the region topographically diverse, but geologically...
