Review highlights fire, insect, and disease threats to Christmas trees, suggesting improvement measures.
Fire, vertebrate, insect, and pathogenic disease hazards to three major Christmas tree species are reviewed, together with remedies. Several times as many insect pests have been reported in Scotch pine (Pinus sylvestris) as in either Douglas-fir (Pseudotsuga menziesii) or balsam fir (Abies balsamea) Christmas tree plantings. Limited information suggests that Christmas tree quality can be profitably improved through a higher level of protection.
