Description:
A map of ecoregions of Alaska has been produced as a framework for organizing and interpreting environmental data for state, national, and international inventory, monitoring, and research efforts. he map and descriptions for 20 ecological regions were derived by synthesizing information on the geographic distribution of environmental factors such as climate, terrain including information of physiography, geology, glaciation, permafrost, and hydrologic features, soils and vegetation. ualitative assessment was used to interpret the distributional patterns and relative importance of these factors for influencing the character of the landscape from place to place. he specific procedures and materials used to delineate the ecoregion boundaries are documented and a description of the environmental characteristics that occur in each resultant ecoregion is provided. n accompanying map shows the distribution of the ecoregions and the transitional areas along their boundaries.
