Thanks David for the correction! Please clarify further - with a reference
if at all possible.
Like Brian, I had assumed that % AGB (above ground biomass) is generally
higher in forests than grasslands.
Cheers
Nat

not true. a very bad generalization. all i will grant you is that grasses
arose recently in botanical evolution because they are highly successful
competitors to repopulate exposed, unforested soils -- especially drylands
with lower levels of rainfall and soil mineral nutrient supplies. the
grasses and their herbaceous companions quickly cover these denuded niches
in the biosphere to shade and cool the land, filter rain and snowfall, and
begin to rebuild subsoil biomasses -- living, dead, and decaying.

forests tend to hold their biomass within the above ground parts and
prairies/grasslands/ag. tend to hold biomass closer to or below the ground
level.
