Welcome to the Alaska Arctic Geoecological Atlas

The Alaska Arctic Geoecological Atlas is an important collection of vegetation plot data and geoecological maps from Arctic and near-Arctic Alaska.

The Vegetation Plot Archive contains ground-based vegetation plot data, associated environmental data and related information from over 3,000 plots in Arctic and near-Arctic Alaska, as well as a few sites in the Canadian high Arctic. The AAVA uses Turboveg for Windows (Hennekens and Schaminee 2001), which is a comprehensive data management system for vegetation-plot data.

The Map Archive is a multi-scale collection of detailed geoecological maps and related material. It includes maps at seven different hierarchical scales — from integrated terrain maps at relatively fine scales (1-m2 plots) to raster-based map products derived from satellite data and digital elevation models that cover the entire Arctic. Geoecological themes include geology, topography landforms, surficial geomorphology, soils, and vegetation.

AAGA vegetation archive datasets can also be discovered and previewed through GIS-based maps at AAVA on ArcGIS Online.
