TreeKeepers Update #5

Posted on

A big thank you to all that came out on Saturday to help remove invasive species at Perkins Passage. It was a hot one but we managed to remove a lot of buckthorn and start replanting at this site. A special thanks to Councillor Dave Gittings (middle photo) who showed his support for urban forestry in Oakville by taking part in this event. And a thank you to Panera Bread (located on North Service Rd) for providing us with delicious treats. We hope to do more work at this site later this summer.

Ash tree update:

Last week the Town of Oakville began injecting more municipal street and park ash trees with TreeAzin to protect them against Emerald Ash Borer (EAB) as part of the Town’s 2016 ash tree treatment program. If you see an ash tree in your neighbourhood with a green ribbon it means it has been injected and treated for EAB. A red ribbon means that the tree has NOT been treated and will be removed.

Wondering what you can do to help? Here are some tips:

  • Water treated ash trees – those with green ribbons
  • Remove dead and dying ash trees
  • Replant lost backyard ash trees with a native one

Contact Oakvillegreen (email: if you would like more info or to help plant and care for the trees in your neighbourhood.
