Ornamental Pears: invasive, high-maintenance, little benefit to our overall urban forest canopy
The flowering Callery pear trees are coming into bloom, look around, as you may see just how invasive they trees have become along our streets and in our parks.
As you drive and walk around this next week or two, pay attention to the white flowering trees along the highway and your favorite hiking trail. These are all invasive flowering Callery pear that have seeded themselves in and are now outcompeting even invasive bush honeysuckle in many places.
Make note of where they are so you can plan efforts on their control in this year’s work plan, in your landscape if needed. Like invasive bush honeysuckle, they are much easier to remove when they are smaller and less established.
Share this information with your local tree commissions, landscapers and property maintenance personnel.
