Remote Sensing of Ecosystem Condition and Resilience

Ecosystem condition tends to be highly dynamic in response to natural variability in climate, extreme climate events, disturbance events, and human land use activities. Satellite imagery provides a powerful tool to enhance our understanding of ecosystem change at a landscape scale. This research integrates diverse sources of satellite imagery with ancillary datasets to explore how ecosystems...

Cheatgrass and Medusahead

Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Nitrate Contamination in the Albuquerque Basin

Globally, nitrate is the most ubiquitous groundwater contaminate including within the Albuquerque Basin in New Mexico. Ingesting high concentrations of nitrate (> 10 mg/L as N) in drinking water can lead to an increased risk of cancer and in infants, methemoglobinemia. Historical groundwater sampling in Albuquerque and Kirtland Air Force Base have found high (> 10 mg/L as N) and sometime...
