Abstract:
It is an individual tree growth model. It uses a list of trees, each with
exact measurements, as input data. The user can specify periods of
growth, in five year increments, and management such as thinning ,
fertilizing, and pruning. For each of the requested activities, the individual
trees are modified to reflect the effects of the actions. The program
produces stand statistics at each step, and yield tables after final harvest
of the stand.
Presently, ORGANON models two areas -- Mixed conifer,
young-growth forest stands of Southwest Oregon, which have
approximately 80% basal area in Douglas-fir, grand fir, white fir,
ponderosa pine, sugar pine, and incense-cedar (SWO version); and
young-growth Douglas-fir stands of the Western Willamette Valley of
Oregon (WWV version). The model can project development of both
even-aged and uneven-aged stands with ages ranging from 20 to 120
years. (Although it will project uneven-aged stands, the WWV version
was developed primarily from data taken from even-aged stands.) The
map shows the areas from which data was drawn for development of the
two version
