Current Research

The scientist investigates interactions among human land use and management, forest vegetation, and natural disturbance processes (principally fire and defoliating insects) across large landscapes in time and space. Under this guiding theme, the scientist develops landscape models to synthesize information across scales and scientific disciplines, and applies those models to investigate the emergent consequences of these interacting phenomena. The cumulative effects of these interactions result in persistent spatial legacies that often constrain future management options and may impact ecosystem resilience to future change.

The scientist also designs field studies to address fundamental knowledge gaps limiting the understanding of disturbance processes and effects. Some focal areas include: 1. how landscape legacies from past forest management patterns can either buffer or amplify insect outbreaks; 2. how disturbance intensity or severity (e.g., fire or insect defoliation) many be scaled up using different remote sensing platforms; 3. how fuel loading and fire intensity relates to belowground soil heating, and its consequences for the restoration of fire-prone ecosystems.

Such field study enable selective replacement of empirical model components, dependent on past observations, with process-based model components based on mechanistic understanding and theoretical underpinnings. This last objective is critical because the novel conditions anticipated within the global context of anthropogenic climate, atmospheric, biodiversity, and land cover changes suggest that the empirical relationships of the past will become increasingly unreliable in the future. Hence the overarching goal of the scientist’s research program is to advance both the state of the art in landscape disturbance and succession modeling and the field of landscape ecology as it applies to disturbance and change within forested ecosystems.

Research Interests

Emergent themes within the scientist's research program include: 

  • Restoration of temperate woodland and savanna ecosystems through effective application of fire
  • Modeling of wind-assisted insect dispersal
  • Approximating "tri-trophic" (i.e., forest, insect, natural enemy) interactions affecting outbreak dynamics in time and space within forest landscape models
  • Addressing the human dimensions of uncertainty affecting the possible future conditions of forested landscapes using "strategic foresight" and "participatory modeling" techniques.

Why This Research is Important

Forests provide essential ecosystem services across the globe including carbon storage, water quality, climate regulation, wildlife habitat, and biodiversity. Yet forests are increasingly stressed by a range of agents that are threatening the resilience of these systems and the ecosystem services they provide. Forest landscape models synthesize what is known and unknown regarding drivers and processes underlying forest dynamics through time and space, and can enable projections of potential futures in forested landscapes that might be realized. Still, forest disturbance interactions in time and space are complex, and require both conceptual and emprical advances to ensure their results are grounded in good science. Fortunately, data collection technology (e.g., remote sensing, data loggers, molecular techniques), analytical tools, and computational power continue to increase, facillitating more effective study and modelling of such complexity. Such research will enable the development of next-generation landscape models that, ultimately, provide decision support for land managers based on the best available science.
