What does it mean?
Both tree hunts were a huge success, due to the participation of volunteer tree counters and the generosity of homeowners who allowed their trees to be examined. Typically, about one third of the trees in an urban forest are found in parks and on streets. More public trees than is typical were surveyed in the central area of Dundas and somewhat fewer in the South Street area. A broad variety of trees grow in these two areas of Dundas.
Maples predominate in central Dundas and Eastern White Cedar in the South Street area. Experts suggest that no more than 10% of the trees in a community should be of the same genus. A pest or disease epidemic that targeted maple or cedar trees would have a serious impact on the urban forest in the areas of Dundas included in the tree inventory.
A significant proportion of the maples found were Norway Maples. Norway Maples are popular landscape trees because they are tolerant of pollution, poor soil and difficult sites. Unfortunately, they are highly invasive. The seedlings of these prolific trees shade out native species in natural areas such as ravines and woodlands. Homeowners should choose native maples, such as Sugar Maple or Red Maple, or another type of native tree when planting new trees on their properties. These neighbourhoods are home to several very large trees. In addition to their heritage value, large trees are important to the environment. Benefits from trees are directly related to their size, especially their leaf area. Up to a quarter of the trees surveyed had serious defects (e.g., rot or large dead branches) that could present a potential hazard or become a liability. These trees need attention, ideally by an arborist.
Copies of both reports (2007 and 2008), which include information on city trees needing attention by an arborist, were sent to the City of Hamilton.Results from the first tree count were presented to the Dundas Community at a public meeting in May 2008. Results from the second tree count (Dundas Trees Count Too) will be presented by Environment Hamilton to the public in 2010. The inventories provided key information on potential heritage trees for the 2009 Dundas Valley Heritage Tree Hunt. The inventories, along with the Heritage Tree Hunt, form the basis for the ongoing efforts of the Dundas Valley Tree Keepers to identify, document, honour, protect and propagate special trees in the Dundas Valley. The Dundas Valley Tree Keepers hope that residents of the Dundas Valley will learn more about trees through the tree counts. We trust that reviewing the tree-count results will inspire you to appreciate trees, maintain the health of the trees on your property and consider planting a native variety the next time you add a new tree.
