An Integrated Ecosystem Model for Alaska and northwest Canada

The Integrated Ecosystem Model (IEM) project is a multi-institutional and multi-disciplinary effort aimed at understanding potential landscape, habitat and ecosystem change in Alaska and Northwest Canada.

Due to the collaborative nature of the IEM project, data and materials are housed in different locations.

We know that the physical and biotic components of high latitude ecosystems—hydrology, disturbance (e.g., fire), vegetation, and permafrost—are tightly linked and sensitive to climate. The IEM provides a dynamic model framework that allows exploration of the impact of climate variability and change on these ecosystem components, while also addressing the interactions and feedbacks among components.

The ultimate aim of the IEM is to provide resource managers and decision makers with scenarios for potential changes in landscape structure and/or ecosystem structure and function. In turn, these scenarios are intended for use as inputs to resource- or sector-specific impact models and decision support tools.
