Landscape ecology

Decision support models

The aim of these models is to develop spatial representations of ecosystem functions and benefits across large landscapes and to enhance these values by prioritizing management efforts. Web applications provide a direct resource for interacting with the models to view data layers within a GIS-lite platform and to manipulate model weights to customize spatial priorities based on user needs.

Machine learning for the prediction of ecological processes

Ecological systems are examples of complex and adapative systems where many components of the biotic and abiotic world interact across many spatial and temporal scales to create emergent ecosystem properties such as clean water, clean air, biomass production, wildlife habitat, and carbon sequestration, to name a few. Predicting these processes requires models that can capture this complexity through statisical relationships

Multi-scaled drivers of Rim Fire severity

Local drivers of severity varied across ownerships and progression days revealing shifts in bottom-up and top-down controls. Strong spatial autocorrelation among predictors makes inference on dominant environmental drivers difficult.

Fuel treatment effectiveness in wind-driven wildfires

Compared random forest with sequential autoregression to determine how the importance of environmental and spatial predictors varied spatially for fire severity

Landscape simulation modeling

Landscape simulation models represent major processes driving system level behavior including competition, succession, dispersal and disturbances. These models vary in their complexity and motivations depending on the objectives of the modeling.
