Abstract:
contents of the model
NORM is a forest stand growth model (non-spatial sinufis/gle tree model) based
on the tree-list approach, and designed to (1) predict sustainable timber
harvests from the rainforests of north Queensland, and to (2) assess the
impacts on those forests of timber harvesting. The model uses recognises over
200 tree species, using 41 equations to predict diameter increments of
different species groups, and several equations to predict mortality and
recruitment in different species groups. Full details of the model are given
in "Modelling Forest Growth and Yield" by J.K. Vanclay., CAB International,
1994, ISBN 0 85198 913 6
principles of the model
Models individual trees on a per-hectare basis, with separate equations to
predict tree growth (diameter increment), mortality, and recruitment
(at 10 cm diameter). The model deals with growth and mortality of all/any
species, but only predicts recruitment of 100 species. Recruitment is modelled
in two stages: first predict the probability that there is any recruitment of
the target species, then predict the expected amount given that some is known
to occur. There are also functions to predict commercial value, defect,
volumes, etc.
