Trees and Shrubs

Trees and shrubs are the backbone of our urban, rural, and wilderness landscapes. Rarely do we consider them perennial plants; however, many are perennial in their habit. Like many perennials, they are vulnerable to disease and pests. For example, in the 1960s, Dutch Elm disease killed many Elms. Dead Elms can still be seen in the south and central Ontario countryside. Today, Emerald Ash Borer and Asian Longhorned Beetle threatened our trees. Federal Ministry Orders prohibit moving any ash material and firewood of all species from specific areas of Ontario, Quebec, and the United States in an attempt to prevent the spread of Emerald Ash Borer and Asian Longhorned Beetles. Campers are urged to buy local wood at campgrounds and asked not to bring firewood from other areas.

Increasingly, trees are being threatened and need to be protected and nurtured.
