The Growing Problem of Invasive Callery Pear Trees Across the US
As the popularity of Callery pear trees continues to increase, so does the number of states that are facing the detrimental effects of their invasive nature. The Callery pear tree, also known as Pyrus calleryana, is native to China and Korea, and was introduced to the United States in the early 20th century. Despite its attractive white flowers, the Callery pear tree has become an invasive species in many parts of the country, with New Jersey, Virginia, and North Carolina being the latest states to declare it a nuisance tree.
The Callery pear tree has a tendency to outcompete native plants, resulting in a decrease in biodiversity and a decrease in the quality of the soil and water. It also has a shallow root system which can cause damage to roads, foundations, and other infrastructure. As a result, these states have taken steps to limit the spread of the Callery pear tree and are encouraging the removal of existing trees.
