Printable Version - Ferguson Township alerts residents to this year's first confirmed case of oak wilt

June 28, 2017

Ferguson Township residents need to be aware of two confirmed cases of oak wilt disease in 2017, 
confirmed on Cherry Ridge Road. The Township aims to provide you with educational information
about oak wilt, and make you aware of the Township's recent actions to stem the spread of the disease. Further mitigation work is planned for the spring of 2017.

Oak wilt is a fungus that attacks all species of oak trees, but Red Oak and Pin Oak are the most susceptible. Once infected, an otherwise healthy tree rapidly drops its leaves during the summer months and dies while other nearby trees still have green leaves.

Oak wilt can spread through root grafts to nearby trees, and can be carried by bark beetles that feed on an infected tree and then move to a healthy one.

Township Ordinance 1023 declares that it is unlawful to prune oak trees from April 1 through October 31 each year, as this is the time the beetles that spread the fungus are most active. It also declares that it is unlawful to climb oak trees using spurs or spikes for any reason except tree removal.

Township Resolution 2016-32 allows Township staff to treat or cause to be treated at-risk oak trees within 150 feet of an infected oak tree, using a fungistat to abate the spread of the disease. In addition, the resolution allows staff to perform trenching to break tree root grafts, and to remove whole infected trees all at no cost to the property owner.

Please be aware of the signs of oak wilt and report any trees showing symptoms to Lance King, Township Arborist. For more information about oak wilt, contact him at (814) 238-4651, or email
