Planting Frequencies and Trends of Street Trees in Southern Ontario Municipalities    (View PDF)

J.R. Pickering and R.G. Perkins

Abstract: Traditionally, municipalities have relied upon a rather narrow range of species for their planting programs. A survey of 23 municipalities in southern Ontario indicates that upwards of 90% of all street trees planted during the 1 970's comprised six species and their cultivars. Trends in the use of individual species have shown changes during the same period. Urban forest managers must be careful not to sacrifice short term gains for long term management difficulties through reduced species diversity.
