Abstract:The experiments reported in this paper indicate that hybrid poplars are so highly susceptible to the inhibiting effect of grass that there is only a remote possibility of discovering types that can be established successfully on sod land without site preparation. The author suggests that hardwood species which volunteer naturally on abandoned fields may possess greater inherent resistance, and that with these species selection and controlled breeding may result in the discovery or creation of clonal variants capable of successful establishment on abandoned farm land without previous site preparation.

- 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.
