Community Science in Grand Canyon

Aquatic insects are important components of riverine foodwebs as they are prey for fish, birds, bats, lizards, and spiders. The closure of Glen Canyon Dam in 1963 fundamentally altered the hydrology, water temperature, and turbidity of the Colorado River through Grand Canyon. These changes, along with competition with invasive species and limited food availability have led to the decline and...

Is timing really everything? Evaluating Resource Response to Spring Disturbance Flows

Glen Canyon Dam has altered ecological processes of the Colorado River in Grand Canyon. Before the dam was built, the Colorado River experienced seasonable variable flow rates, including springtime flooding events. These spring floods scoured the river bottom and enhanced natural processes that sustained the Colorado River ecosystem. Since the dam’s construction in 1963, springtime floods have...

GCMRC Data Applications

The Grand Canyon Monitoring and Research Center develops and collaborates with other science centers to create online data applications that provide access to project data as it becomes available to the public. Some of these applications provide data in near real-time, while other project data are updated at some regular interval (annually, quarterly). Content listed here include applications that...

Terrestrial Riparian Vegetation Monitoring: How One Square Meter Can Tell the Story of 245 River Miles

The goal of Grand Canyon Monitoring and Research Center’s (part of the Southwest Biological Science Center) riparian vegetation monitoring program is to assess changes and trends in plant species composition and cover and relate those changes to Glen Canyon Dam operations, river hydrology, climate, and geomorphology. Monitoring is done by annual field-data collection on plant cover and diversity...

Overview of Riparian Vegetation in Grand Canyon

Riparian areas are conspicuous belts of dense, green vegetation along streams and rivers, and can be considered “ribbons of life”. Despite covering less than 2 percent of the land area in the southwestern U.S., riparian areas tend to have high species diversity and population density, making them valuable to managers, scientists, and the public. These unique ecosystems act as a link between dry...
