Wood, crops, and yard and animal waste are examples of biomass.
Biomass is considered a good measure of plant dominance on a site because it reflects the amount of sunlight, water and minerals a plant is able to capture and turn into plant mass.

There are many methods to directly measure biomass of herbaceous plants, but, it is difficult to estimate biomass of shrubs and trees.
