A state-dependent dynamic crown fuel model is proposed. The model is a
distance-dependent tree model. The model simulates crown characterist
ics such as foliage weight, crown base height, crown length and crown
closure. The model is based on simplified dimensional growth relations
hips combined with photosynthesis and respiration. Preliminary tests o
f the model using coefficients derived from red pine, have shown that
the model effectively simulates crown characteristics under a range of
sites and silvicultural interventions.
