Abstract:Cambial tissue died following application of aerosol tree and log marking paint to the bark of pole-and sawlog-size sugar maples (Acer saccharum Marsh.) in nine northern hardwood stands in Michigan. Cankers and stem swelling from callus formation developed on 76 of 220 sugar maples observed in these stands. The swelling will bias diameter measurements for research and inventory purposes. Cankers reduce log quality and may be infection courts for wood decay fungi.
Toxicity of liquid tree marking paint to cambial tissue has been noted previously: aerosol formulations are more toxic than the liquid form. Foresters working with northern hardwoods should avoid using either form to label study trees or crop trees that are to be left standing for any length of time. These can be labeled with quick-drying enamel, which has shown no abnormal effects.

- The Journal of Forestry is the most widely circulated scholarly forestry journal in the world. In print since 1902, the Journal has received several national awards for excellence. The mission of the Journal of Forestry is to advance the profession of forestry by keeping forest management professionals informed about significant developments and ideas in the many facets of forestry: economics, education and communication, entomology and pathology, fire, forest ecology, geospatial technologies, history, international forestry, measurements, policy, recreation, silviculture, social sciences, soils and hydrology, urban and community forestry, utilization and engineering, and wildlife management. The Journal is published bimonthly: January, March, May, July, September, and November.
