Simulations on the occurrence of dead trees in natural pine stands.

open access: yesSilva Fennica, 1989
The study aimed at recognizing the phases of forest succession where dead trees most probably occur. The model simulations showed that the increasing occurrence of dead trees culminated after the canopy closure.

Crown condition as an indicator of the incidence of root rot caused by Heterobasidion annosum in Scots pine stands

open access: yesSilva Fennica, 2002
Trees in three Scots pine stands seriously infected by Heterobasidion annosum were classified according to their crown condition into four classes, from healthy to dead trees. After cutting the stands, the classification was compared with the symptoms
