Ohio became the first state in the country to ban the popular but invasive Callery pear trees — a species usually sold under cultivar names such as Bradford, Cleveland Select and Chanticleer.
Now legislation is being proposed in Missouri for a similar ban, while the Kansas Department of Agriculture also considers how to curb the spread of the popular but invasive ornamental pear trees.
The Missouri proposal would prohibit nurseries from selling or distributing several invasive species, including the Callery pear, Japanese honeysuckle and climbing euonymus. The proposed legislation would take effect Jan. 1, 2025.
The Kansas Department of Agriculture's proposal would prevent anyone from bringing a Callery pear into the state or moving one within the state, as of Jan. 1, 2027.
Callery pears have been popular for decades because of their white flowers in spring and their red foliage in fall.
But they’re escaping cities and suburbs and spreading into prairies and woods, where they have few predators and so outcompete native plants. Unlike many other trees, this species doesn’t die if it’s chopped down or burned. That means land managers have to use herbicide.
Each year, workers at Johnson County Park and Recreation District spend many hours trying to root out the species on public land.
Kansas’ agriculture department could adopt the proposal this year, but it wouldn’t enforce the restrictions — which carry potential criminal penalties for violators — until 2027.
The proposal is called a quarantine. Property owners wouldn’t be required to cut down existing Callery pears, but no one would be allowed to move live ones, their seeds or their rootstock.
That would mean no bringing these things from other states or selling or giving them to someone within Kansas.
Kansas and Missouri conservation groups and local governments have launched a public education campaign in recent years to explain why the trees cause problems.
