Current Research
Forest monitoring is critical for effective decisionmaking, yet our understanding of impacts, trends and where things are headed is often insufficient for societal needs. This scientist's current research emphasizes monitoring at the landscape scale using diverse remote sensing approaches. He is a team member of the USDA Forest Service's ForWarn system which tracks forest change across the Conterminous US using MODIS imagery at near-real-time, and he also works to understand the longer-term change in forests using historical MODIS datasets. This high frequency, but coarse resolution data are adept at tracking land surface phenology and how it changes with seasonal climate variation, disturbances, such as fire, drought, insect defoliation, hail or wind damage. He tracks the initial disturbance impacts and longer-term responses. These are both important as many disturbances are ephemeral while others have more substantial impacts that last the growing season or longer. These monitoring data also permit monitors to systematically track recovery after disturbance including the cumulative effects of multiple disturbances. Understanding disturbance-recovery dynamics as well as multiple disturbances provides researchers and forest managers with the ability to describe and even track resilience at landscape scales.
The scientist's research also includes understanding the landscape tradeoffs associated with wildland fire and how this intersects with planning and policy issues. He was part of the National Cohesive Wildland Fire Management Strategy Science Team and he continues to pursue lines of research that relate to fire's broad scale occurrence and its landscape impacts or risks.
