About Us

We are an interdisciplinary team of scientists whose research focuses on the ecology and management of interacting disturbances perceived as significant threats to human communities, including fire, climate change, insects, disease, and invasive plant species.

Research Focus Areas

Forest pathology
Arrow.Conservation strategy for Alaska yellow-cedar in the North Pacific coastal rain forest
Arrow.Bioactive compounds in trees and shrubs that reduce infection from P. ramorum, the pathogen that causes sudden oak death
Arrow.Managing heart rot in live trees in second-growth forests of southeast Alaska

Arrow.Inundative release of beetles to control leafy spurge
Arrow.Use of fungi and nematodes as biocontrol agents of amber-marked birch leafminer
Arrow.Risk mapping of native and exotic defoliators affecting subsistence berry crops in Alaska
Arrow.Impacts of bark beetles on Western forests
Arrow.Landscape dynamics of mountain pine beetle

Invasive plants
Arrow.Control of Scotch broom in forests
Arrow.Effects of fire and ungulate herbivory on invasive plants in coniferous forests
Arrow.Fuel reduction and seeding effects on juniper woodlands

Climate change
Arrow.Ecosystem and species responses to historical and future climate variability and change
Arrow.Development of models and tools to better assess, manage, and mitigate carbon
Arrow.Decision support systems that consider climate change

Disturbance and restoration treatments – wildlife effects

Arrow.Dry-forest restoration impacts on spotted and barred owl interactions
Arrow.Impacts of dry-forest restoration on small mammals
Arrow.Assessing whitebark pine restoration using Clark’s nutcracker cone harvest rates

Arrow.Ecosystem dynamics following wildfire
Arrow.Short and long-term impacts of fuel reduction treatments
Arrow.Biodiversity and ecological resilience to historical and novel disturbances in fire-prone dry forests

Landscape assessment, modeling, and management
Arrow.Potential climate change interactions with vegetation, disturbance and management, and development of adaptation and mitigation strategies
Arrow.Efficient monitoring and assessment of change in forests at regional scales
