What is Oakvillegreen?2014-10-04 at 11-13-27

Oakvillegreen Conservation Association (OCA) is a non-profit advocacy environmental organization with a 15-year history of protecting and enhancing nature and promoting a green Oakville. OCA has achieved success in advocating for natural heritage system planning, urban forest protection, a natural trails plan and against an incinerator, cosmetic pesticide use and new developments in natural areas. We have engaged thousands of volunteers in enhancing local parks and green spaces and have planted over 20,000 trees and shrubs. In collaboration with municipal, corporate and community partners, OCA volunteers plant native trees and shrubs and steward over 50 sites in Oakville. We connect diverse audiences in the community to nature through presentations, hands-on stewardship events, workshops, guided hikes and cycle tours. Our free, grade K to 12, curriculum-connected school programs, are delivered to thousands of students each year.

We strive to create a LIVING Oakville, with restored nature and a community connected to nature!

Fall Tree Planting

TreeKeepers Update #14

Posted on

Here’s what the Oakville TreeKeepers have been up to this week:


A small but mighty crew began the last of mulching street and neighbourhood trees along Sixth Line between Munn’s Ave and Glenashton Dr. These trees have evident damage from being struck by lawnmowers or other maintenance equipment. Mulching is a great way to mediate these effects and prevent more damage.

Before mulching…
After mulching.
