Reduce One Invasive Species 2022 - Callery Pear
Flowering branch of Callery pear
Reduce One Invasive Species Challenge
Each year MC-IRIS chooses one invasive plant species on which to focus education and control efforts. 2019 was Asian bush honeysuckle, 2020 was purple wintercreeper. For 2022 we have chosen Callery pear - join us to help reduce the amount of this invasive tree in Monroe County!
As documented in this April 2021 video by WTIU, reporter Emma Atkinson shows just how much Callery pear we have in Monroe County, and why it's a problem.
Callery pear has escaped from city green spaces, residential yards, and church and business landscaping. It spreads easily to neighboring properties, along right-of-way corridors, and into our surrounding forests, wetlands, and other sensitive natural areas; negatively impacting our watershed.
Through Reduce One Invasive Species, we focus on one invasive plant species at a time, learning how to identify it with confidence, and discovering how to control and dispose of it with greater efficiency. By working together we can limit further spread.
Look for more information on Callery pear, including management and disposal recommendations as well as special events and opportunities, to be announced in 2022!

Why should you control Callery pear?
Is this the same thing as Bradford pear?
Callery pear is the parent species of Bradford pear, which is one cultivar of Callery pear. Other cultivars include Cleveland Select, Autumn Blaze, Aristocrat, Red Spire, Chanticleer, and many others. All cultivars of Callery pear are invasive - there are no exceptions.
What are the rules covering Callery pear in Monroe County?
In Bloomington: Due to spreading infestations, Callery pear is no longer planted by the City of Bloomington, and it is disallowed in new developments by the City's Unified Development Ordinance. Erin Hatch, Urban Forester with the City of Bloomington, is the best person to contact to remove Callery pear located in sidewalk green strips and other right-of-way areas. These are considered city trees. Erin notes, “If adjacent property owners wish to conduct tree work, such as removal of these trees, at their own cost, they can submit a tree work permit application, found on the webpage for the City's Urban Forest.” Visit this page https://bloomington.in.gov/about/trees
TreeKeeper website is an online inventory of almost all of our street trees and some of our park trees in Bloomington. Visit this page https://bloomington.in.gov/about/trees
Outside Bloomington: .Callery pear cannot be used to meet the minimum standards required for site plan approval for landscaping new commercial sites or multi-family developments, or when street trees are required for subdivisions. You can only use species on the approved native plant list. Details can be found in Chapter 830, the Monroe County landscaping ordinance.
Callery pear has spread from those plantings and dominates the understory of this forest, outcompeting native hardwood trees.
