Abstract
AbstractFollowing a hail storm in the southern Cape Province of South Africa, about 2000 ha of pine plantations were infected by Sphaeropsis sapinea. The timber loss due to S. sapinea infection in compartments prematurely clearfelled was about 28% of volume and 55% of value of potential production. Total predicted volume of timber lost in compartments not felled prematurely was an average of 11.4%. Percentage volume lost increased with age, with the greatest losses being recorded on good quality sites.
