Do you think the you have the largest Callery pear tree in Warren County, OH? Enter to win our Biggest Tree Contest!

As you may already know, as of January 2023, selling or planting Callery pear trees is illegal in the state of Ohio. The ability of the Callery pear to grow quickly and of its cultivars (like Bradford pear) to cross pollinate with each other despite being previously believed to be sterile causes the plant to rapidly spread and outcompete some of our native species. You can find out more about Callery pear and the negative impact it is having on Ohio's ecosystems and wildlife here.

The winner with the tallest Callery Pear Tree will receive a prize at our Annual Meeting (hint: it will help offset the cost to replace this invasive species on your property)! All residents of Warren County, OH are eligible to enter (there are no age requirements). The deadline to enter has passed. Thank you for participating!

HOW TO ENTER:
Measure the circumference of your tree at four feet up from the base and make a rough estimate of the tree’s height. Enter the information with your contact details in the form on this page. 

If your entry is among the largest we will contact you to make arrangements to have the tree measured by our judges.
