Definition
Above-ground biomass is the total mass of living plants, excluding roots, above the soil surface in a given area. It includes stems, leaves, bark, and reproductive structures.
5 Must Know Facts For Your Next Test
- Above-ground biomass is a crucial indicator of ecosystem productivity and carbon storage.
- It plays an essential role in nutrient cycling and habitat structure within ecosystems.
- Measurement techniques include direct harvesting, remote sensing, and allometric equations.
- Forests typically have higher above-ground biomass compared to grasslands or shrublands due to tree density and size.
- Changes in above-ground biomass can indicate ecological disturbances such as deforestation or climate change impacts.
