Mapping Shrub Biomass in the Arctic

Location of study area in northern Alaska.

Location of Toolik Lake study area in northern Alaska. Detail view shows three LiDAR collection footprints in pale green. Red crosses indicate locations of shrub harvest areas within the Toolik LiDAR footprint (figure from Greaves et al., 2016).

LiDAR and orthophotography were used to estimate aboveground shrub biomass near Toolik Lake, AK.

Aboveground Biomass in the Arctic Tundra

AGB shown in Beaufort Coastal Plain and Brooks Foothills ecoregions of the North Slope of Alaska.

The best estimate (50th percentile) of 30-m shrub dominance (shrub/plant AGB) for non-water portions of the Beaufort Coastal Plain and Brooks Foothills ecoregions of the North Slope of Alaska.

Estimates of aboveground biomass for the North Slope of Alaska are provided in a new dataset.

ABoVE Arctic Vegetation Monitoring

Vegetation plot locations across Alaska

Vegetation, soil, and environmental data were collected from over 3400 plot locations in the ABoVE study area.

Vegetation species and other environmental and soil parameters are available from over 3400 plot locations within the NASA ABoVE study domain.
