| 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. |
