In November 1958, an ice storm caused severe bending of stems in young red and Scots pine plantations on the Sandilands Forest Reserve in southeastern Manitoba. A study was carried out to investigate the recovery of bent trees and to determine the extent of permanent damage in the plantations.
Between 50 and 100 per cent of the trees in young red pine plantations were bent so severely that their tops were touching the ground. Scots pine plantations were less severely affected. However, both species showed considerable recovery and little or no permanent damage has occurred in plantations younger than 14 or older than 25 years of age. Approximately one quarter of the trees growing in two dense red pine plantations, 16 and 22 years of age, were judged to have been permanently damaged.
