Can you smell rotting fish in the air this spring? That’s the awful Callery pear tree, also known as Bradford pear, one of the earliest trees to bloom and one of the most terrible threats to Indiana’s natural landscapes. Overused by landscapers due to its showy blooms, fast growth, and upright stature, this tree is wreaking havoc on Indiana’s biodiversity by spreading rapidly to wild open spaces, where seeds from bird droppings and cross-pollination create monoculture landscapes of dense thickets with sharp thorns – sharp enough to puncture a tractor tire! – that choke out native species and diminish crucial habitat and food for pollinators.
The Bradford pear’s showy white spring blossoms smell disgusting (many compare it to dead fish) yet these trees are a popular landscaping choice for many who don’t realize how devastating they are for Indiana’s environment. A weak tree prone to wind and ice damage, they are also a hazard with a very short lifespan of only 20-25 years. These "Frankenstein trees" are so detrimental to Indiana’s future that there is even a bounty placed on them this month in Lawrence County to encourage homeowners to cut them down. “If you didn’t know how harmful these trees were, and planted one on your property, we’re asking you to cut it down,” says the Lawrence County KIC (Keep Invasives in Check). “In return, we’ll give you a replacement tree.”
Why is it still legal to buy and plant such a dangerous tree, despite the threat they pose to almost every native species in Indiana? Tragically it comes down to money, as these trees earn nursery owners millions of dollars each year and the Indiana Invasive Species Council is prohibited from banning any plants that could cause economic harm to nurseries and small businesses. That’s why it’s so important to educate the public to stop buying them. Learn more in yesterday’s IndyStar article: “Bradford pear trees are highly invasive. This is why they aren't banned in Indiana.” https://www.indystar.com/story/news/environment/2021/04/06/council-considers-banning-invasive-bradford-pear-tree-indiana/6988023002/
We laughed at a joke shared recently on the Indiana Native Plant Society page: “What’s the best way to prune a Bradford pear tree?” The answer: CUT IT DOWN. Protecting Indiana’s forests starts at home in your backyard. Please do your part to remove invasive species before they spread into the natural areas we love and protect.
