* Metric Name: Shrub Cover  

* Tier: 1  

* Data Vintage: 2021  

* Unit Of Measure: Fractional non-overlapping absolute cover; continuous variable from 0 to 1.

Total shrub cover as measured by the fractional non-overlapping absolute shrub
cover, viewed vertically. Provides a first order measure of vegetation type
when combined with parallel observations of tree and herbaceous cover. Data
from the National Land Cover Database (NLCD) are used for training, and NLCD
definitions for cover (for example, the distinction between tree vs shrub) are
expected to be similar in the CECS data sets.

* Creation Method: Machine learning (Random Forest) using the National Land Cover Database for training and Landsat observations as predictors. See[ https://doi.org/10.1029/2021AV000654](https://doi.org/10.1029/2021AV000654) for further information.
