GROMIT simulates growth and mensuration at an individual tree level, calculating carbon
and water balance. It was initially developed for coniferous forest plantations, mainly
Sitka spruce in England.
Empirically leaf photosynthesis is calculated form incident radiation and temperature,
and integrated over each individual crown. Allocation of carbon follows the pipe model
The model can be applied successfully not only for mensuration purposes but also for
climate change questions and long-term effects thereof on forests.

VI. Additional remarks
GROMIT was recently successfully applicated in the EU-project LTEEF ("Long Term Effects of CO2 increase and climate change on European Forests", project-leader G.M.J. Mohren). It is also applied within the ongoing European project ECOCRAFT (climate change impacts on European forests , project leader: P.G. Jarvis).
