Category Growth
Model type Empirical growth & Yield models
Sub-type Distance independent tree model
Level Stand/plot
Time step
Time scale
Range of applicabiilty (region, ...) Geogr. : northern half France
Stands : almost pure, even-aged Beech
Age : 10-200 years
Time resolution : 3 years
Silvics : "diffuse" thinnings of any weight, type and rotation are acceptable ; predictions correct iff stand Rdi larger than 0.4 ; outside, qualitatively sensible, few validation data available.
