Landscape ecologists at ACCS synthesize biological, geophysical, and anthropogenic spatial data to answer questions of ecosystem intactness, function, and service at broad spatial scales. Many of Alaska’s iconic species such as salmon, caribou, and a myriad of migratory birds range across immense habitats spanning jurisdictional boundaries, which require expansive analyses. Our research combines multiple factors influencing Alaskan and Arctic ecosystems including climate, biological succession, cumulative human impacts, and resource management decisions.
We develop statewide datasets applicable to conservation planning for state, federal, and municipal governments as well as non-profit and tribal organizations. To view or acquire data from our completed projects, please visit our data catalog. Project reports and peer-reviewed publications are accessible from our publications page. Spatial variation in the climate and physiology of Alaska create diverse and dynamic ecological communities. Remotely sensing ecological communities and modeling species habitats spatially are fundamental to understanding ecosystems across landscapes in Alaska. Given the rapid rate of climate change coupled with related geophysical changes and the increasing impacts of human activities and development, ecological communities and ecosystems in Alaska are dynamic entities that vary in resiliency. We study the cumulative impacts of simultaneously changing spatial and temporal factors that drive ecological change.

Jamie Trammell, Ph.D., Southern Oregon University
Landscape Ecologist | 541-552-6496 | trammelle (at) sou.edu | Publications
Jamie is a landscape ecologist at Southern Oregon University in the Department of Environmental Science & Policy focused on developing actionable conservation science and management-relevant environmental planning. His specialty is applying Geographic Information Systems (GIS) to complex landscapes, with a specific focus on socio-ecological interactions. He continually works to translate disparate data sources into a common geospatial framework for landscape-level analyses, in both aquatic and terrestrial systems, to facilitate visualization and communication. Jamie is particularly interested in using alternative landscape futures and scenario analysis to better plan for natural resources, both wild and urban, in the future.
