Needle droop of pine has caused considerable apprehension among foresters in the Lake States. On the whole, red pine has been unusually free of highly destructive insects and fungi. When needle droop was first observed several years ago, it appeared as if the future of this fine forest tree might be clouded. It is reassuring, therefore, to find that at the present at least needle droop should not be the cause of great alarm because it appears to be the result of unfavorable factors, such as drought, heat, or frost.
