"Our native ash trees just don't have any resistance to it. All of our native plants are potentially vulnerable to invasive pests."
"This particular pest was imported probably from East Asia. We don't really know what's going to be next."
"We are challenging our community to come out and hike all 17 miles. And people are getting excited about it for sure."
"There's no such thing as bad weather."
In 2022 an emerald ash borer infestation was discovered across 550 acres of protected natural areas at Tyler Arboretum, severely damaging native ash trees. Native ash showed no resistance, prompting closure of trails to protect visitors while crews removed more than 1,500 ash trees from the forested landscape. The emerald ash borer, an invasive beetle from East Asia, continues to threaten ash in North America and Europe. After removals, trails reopened and the arboretum launched a 17-mile trail challenge for visitors to hike and report progress. The 650-acre property features diverse specimens and operates year-round, with limited holiday closures.
