[CBC] Emerald ash borer in Chelsea and L’Ange-Gardien QC

From CBC News – Posted: Sep 10, 2012 11:39 AM ET (http://www.cbc.ca/news/canada/ottawa/story/2012/09/10/ottawa-emerald-ash-borer-chelsea-langegardien.html)

The emerald ash borer has spread to Chelsea and L’Ange-Gardien in Quebec, the Canadian Food Inspection Agency has confirmed.

Movement restrictions — which prohibit the movement of all ash materials including logs, branches and wood chips, and all species of firewood from the affected site — have been put in place, according to a CFIA media release.

Property owners in the affected area have been notified and other regulatory measures will be considered once survey work has been completed.

The presence of EAB has so far been confirmed in five areas in Quebec, and in 27 Ontario counties.

Although it does not pose a risk to human health, it is a highly destructive beetle and has already killed millions of ash trees in Ontario, Quebec and the United States.

It poses a major economic and environmental threat to urban and forested areas of North America.

Breeding new hope: American Chestnuts in the Ontario Landscape

Foresters, landscape architects and conservationists are familiar with the seemingly never-ending parade of native trees on the road to being endangered. In the 70s, Dutch Elm disease changed the Ontario landscape forever as native elms (Ulmus americana, in particular) died, leaving gaping holes in the urban forest and newly shade-less streets. Today, the same bleak outlook applies to ash trees, another long-time landscaping stalwart. The Emerald Ash Borer is the culprit here, whose larvae feed on the inner wood of ash trees creating extensive galleries, slowly killing the tree through an effective girdle as water and nutrients can no longer reach the leaves. Expensive inoculation programmes are the current solution. For example, selected trees on the Experimental Farm are being treated but not all – and protecting street trees around the city would be prohibitively expensive for the city alone to cover (though they are engaged in a programme of selective inoculation with TreeAzin, and encourage ash tree owners to do the same). At Fletcher, we can only wonder for how much longer our Ash Woods habitat area will retain that name. Continue reading
