The Anaktuvuk River Fire was the largest, highest-severity wildfire recorded on Alaska’s North Slope since records began in 1956. The 2007 Anaktuvuk River Fire was an order of magnitude larger than the average fire size in the historic record for northern Alaska and indices of severity were substantially higher than for other recorded tundra burns. An interdisciplinary team assessed fire effects including burn severity, potential plant community shifts, and effects on permafrost and active layers. Observers monumented, photographed, and measured 24 burned and 17 unburned reference transects, starting the year after the fire, and spanning the range of vegetation types and burn severities.

The Integrated Ecosystem Model for Alaska project (IEM) uses down-scaled climate models as the drivers of ecosystem change to produce forecasts of future fire, vegetation, permafrost and hydrology regimes at a resolution of 1km. This effort is the first to model ecosystem change on a statewide scale, using climate change input as a major driving variable. The objectives of the IEM project are as follows; to better understand and predict effects of climate change and other stressors on landscape level physical and ecosystem processes, and to provide support for resource conservation planning.The IEM will provide resource managers with a decision support tool to visualize future landscapes in Alaska. Model outputs...

Concern about invasive species in Alaska is a growing concern, attracting attention from land managers, politicians and the public. Nearly half the new discoveries of invasive plants, animals, and insects in the state are reported by concerned individuals with a general interest in invasive species. The development of a mobile application for invasive plant identification and reporting will help enable the public to gather and share new invasive plant discoveries. This project will result in the development of a decision tool for identifying non-natives plant species, which will provide the foundation for the app. Project staff will also review user-submitted requests for identification assistance, review app-generated...
The geodiversity approach uses topography to define landscape features. Topography can be a proxy for ecological function. For example, topography influences the solar radiation available for plants and animals, the soil characteristics through the likelihood for erosion and deposition, and the characteristics of hydrologic features. Therefore, similar geodiversity types should have the potential for similar ecological function even as the climate changes. We classified the landscape into three topographic feature categories: canyons, ridges, and slopes. Each topographic feature was then clustered into distinct geodiversity types. Slopes were clustered into groups using elevation, slope angle, and yearly solar radiation....
