TREE TUESDAY: Silver Maple Superstars

Leave a comment

Last Wednesday’s 10am inventory session in Crown Point revealed another Silver Maple superstar! Similar to the previous week’s Silver Maple, this fellow was 22.5 meters tall with a diameter of 115 centimetres. Silver Maples can grow up to 35 meters in height and have a diameter of 100+ centimetres.

After inventorying the tree, our Open Tree Map app calculated an interesting list of its annual ecosystem services:Screen Shot 2017-06-22 at 12.47.22 PM.png

Clearly this tree is an important community member – storing carbon dioxide, providing shade, capturing pollution particles, and filtering stormwater! Since the large maple was located in a small urban front yard, much of the ground underneath it was impermeable sidewalk or road surface. This means that it is less able to filter stormwater and reduce runoff than if it were in a park, for example.

We would like to thank the home owners for allowing us to inventory their Silver Maple by displaying the “Count Me In!” sign (below) in their front window. We will be putting these postcards in Crown Point and McQuesten neighbourhood mailboxes over the next few weeks. If you do not get a sign but want your tree to be included in our inventory, please send us an email at
