"Vegetation models" refers to computer programs or mathematical tools that help scientists understand and simulate the growth and behavior of plants and plant communities.
Global response of terrestrial ecosystem structure and function to CO2 and climate change: results from six dynamic global vegetation models. (nature.com)
As the temporal scale is extended, the development of dynamic vegetation models, which respond to climate and human land use as well as other changes, is a central issue. (ipcc.ch)
All 110 simulations predict an increase in global vegetation carbon to 2100, but with substantial variation between vegetation models. (pnas.org)
