Landscape Level Ecological Mapping (R) of Northern Alaska and Field Site Photography
Archive Message: No archive message available
To aid in assessment of ecological, landscape, and climate change in northern Alaska, the previous 2006 ecological landscape map for northern Alaska was updated. The 2012 revisions focused on completing the incompletely mapped portion of the southern NPRA, improving mapping of glacial and outwash deposits within the Brooks Foothills, and improving consistency with existing surficial and bedrock geology maps in northern Alaska. The revisions resulted in 533 ecological subsections, nested within 55 ecosections and 14 ecoregions covering 413,089 km2.
Attributes for the map polygons in an ArcMap geodatabase include information on physiography, generalized geology, lithology, soil landscapes, ecological landscapes, elevation, and climate. The attributes allow production of derived map products such as physiography, generalized geology, and ecological landscapes. The 2012 version of the map will be updated as new information is compiled and revisions are needed.
Products from this mapping analysis were integrated within a web-base map visualization tool with orthoimagery and approximately 14,400 field site photographs. The photos provide site specific information regarding landcover and condition which can assist in a better understanding of the more general ecological landscape delineations.
