USGS 2016 Shrub Height Shrubland Fractional Component

All Shrubland
All Shrubland Components (15.2 GB)
 

Includes all nine components – Shrub, Sagebrush, Bare Ground, Herbaceous, Litter, Big Sagebrush, Annual Herbaceous and Shrub/Sagebrush heights.

Percent Shrub
Percent Shrub (1.98 GB)
The proportion of shrub canopy in each 30m pixel.

Shrub is a continuous field component encompassing all shrub species discriminated by the presence of woody stems and < 6-m in height.

Percent Sagebrush
Percent Sagebrush (0.99 GB)
The proportion of sagebrush canopy in each 30m pixel.

Sagebrush is a continuous field component encompassing almost all species of Sagebrush (Artemisia spp.) including Big Sagebrush (A tridentata spp.), Low Sagebrush (A arbuscular), Black Sagebrush (A nova), Three-tip Sagebrush (A triparta) and Silver Sagebrush (A cana). This component is nested within Shrub as a secondary component.

Percent Bare Ground
Percent Bare Ground (2.36 GB)
The bare ground proportion in each 30m pixel.

Bare Ground is a continuous field component including exposed soil and rocks.

Percent Herbaceous
Percent Herbaceous (2.04 GB)
The annual and perennial grass and forb proportion in each 30m pixel.

Herbaceous is a continuous field component consisting of grasses (live and residual standing), forbs and cacti.

Percent Annual Herbaceous
Percent Annual Herbaceous (1.01 GB)
The annual only grass and forb proportion in each in 30m pixel.

Annual Herbaceous is a continuous field component including annual grasses and forbs. This component is primarily dominated by annual invasive species including Cheatgrass (Bromus tectorum), Medusahead (Taeniatherum caput-medusae), Red Brome (Bromus rebens), or annual mustards such as Tumble Mustard (Sisymbrium altissimum) and Tansy Mustard (Descurainia pinnata). But may contain substantial native annual herbaceous vegetation at higher elevations and in California. This component is nested within Herbaceous as a secondary component.

Percent Litter
Percent Litter (1.77 GB)
The dead plant material proportion in each 30m pixel

Litter is a continuous field component including dead standing woody vegetation, detached plant organic matter and biological soil crusts.

Percent Big Sagebrush
Percent Big Sagebrush (867 MB)
The proportion of big sagebrush canopy in each 30m pixel.

Big Sagebrush is a continuous field component dominated by Big Sagebrush (A tridentata spp.) may include Three-tip Sagebrush (A triparta) and Silver Sagebrush (A cana). This component is nested within Shrub and Sagebrush as a secondary component.

Shrub Height
Shrub Height (2.85 GB)
Average height of shrubs in centimeters.

Shrub Height is the average height of all Shrub in centimeters. This component only occurs where the Shrub component has a prediction.

Sagebrush Height
Sagebrush Height (1.38 GB)
Average height of sagebrush in centimeters.

Sagebrush Height is the average height of all Shrub in centimeters. This component only occurs where the Shrub component has a prediction.
