Top Dying of Conifers from Sudden Cold
Abstract:Western foresters have occasionally been alarmed by the sudden and unexpected appearance of dead tops on thrifty pines. Since insects are a common cause of top-killing in conifers and are often found in the dead pine tops, the killing is usually presumed to be of insect origin. From the investigations reported here it is apparent that sudden temperature changes resulting in killing of bark in the tops is sometimes the primary cause of such dieback, even at temperatures well above those normally considered to be damaging.
