The Ash trees are fading

What is happening?

In eastern Canada, there are five native species of ash and many other introduced species. (Fraxinus pennsylvanica var. subintegerrima) or more commonly Green ash is becoming exceedingly popular. However, the reason for this popularity is not something to admire as it is quite infamous in nature.

Emerald Ash borer

Introducing (Agrilus planipennis) known to everyone who isn’t living under a rock as the Emerald Ash Borer. This beetle is highly destructive and once introduced reeks havoc on ash trees. The Emerald Ash Borer or simply EAB is native to East Asia, once it was introduced to North America it spread quickly and by the time people were aware, the damage had begun. Presently in southwestern Ontario and the Great Lake states, the EAB has killed millions of Ash trees. The EAB preys on both healthy and stressed Ash trees by having the larvae tunnel into the trees vascular system  compromising the delivery of water and nutrients within the Ash tree.

 

 

What can we do?

Major environmental and economic issues associated with the loss of Ash trees due to the EAB has lead to action on regulating and mitigating damage and further dispersal in the future.
Due to the limited mobility of the EAB, the main factors of dispersal have been due to movement of an infected Ash tree’s wood. Transporting infested wood facilitates the movement of the EAB across greater distances. The Canadian Food inspection Agency has implemented restrictions on moving wood from a regulated area to a non-regulated without proper documentation, failure to comply will result in legal ramifications.  The Government of Canada is urging citizens to refrain from moving firewood.
