Method Detail

bwinpro

void bwinpro(stand st)

calculates the mortality for a given influence zone. It expects a class stand and processes all living trees in that stand The specific values for the critical C66 index was derived by the growth and yield data of the NFV for north west Germany. It is supposed that a tree can not live anymore if the calculated c66 value is greater than the critical value. The critical values are set in this method directly. In order to speed up calculation 2% of the number trees can be taken out, before the c66 value are renewed. The maximum is 200 trees.
