Eastern Hemlock Wooly Adelgid update

It has been a struggle to figure our how to proceed with saving the Eastern Hemlock trees on our property. I am more than grateful to the forestry staff from the Long Point Region Conservation Authority who where on the ball and proactive with coming up with actual plans that involved doing something rather than having meetings about meetings to arrange more meetings. 

 They inventoried the hemlock for most of the Peacock Point Wetland Complex (with landowner permission) and subsequently made a treatment plan using established models used in Nova Scotia and parts of the US where this Wooly Adelgid has been killing Hemlock longer than here. 

All the Hemlock received marks. Red and Blue dotted trees received treatment



 The trees chosen for treatment are the largest and healthiest Hemlock. 

 We did manage to get an invasive species grant which was put towards the costs incurred by the LPRCA related to their treatment of our trees. 

 On June 8th 40% of the Hemlock part of the Hobbitstee property received the first treatment and on July 30th the second treatment. One is a faster acting pesticide that is shorter acting and one is a slower acting pesticide that is longer acting. it will take 6-8 months for these chemicals to kill off the pest. 

Trees getting treated



 The way these pesticides where applied is very labour intensive. Each choses tree received what is called basal bark spray which is a ring sprayed at a certain heigh on the bark with no chemical making down to the forest floor. The other was injected directly into the tree with also no chemical making it to the forest floor. A lot of thought has gone into this on my part. 

I believe in letting nature sort it self out, but the reality is that this is an introduced pest. Introduced by carelessness on the part of humans. It came from Asia to the US and was imported into Canada accidentally with trees that came into the country. 

 The Eastern Hemlock are an original growth tree for this are and major part of the habitat related to the Peacock Point wetland complex. I can’t bare the thought of watching all of them die. They are so magnificent. 

 Here is for hoping this treatment came in time and is effective in saving these trees.
