Frequency of Hemlock Woolly Adelgid Information Provided in the Media: Impacts, Ecology, and Citizen Outreach

An analysis of 165 media articles about the hemlock woolly adelgid (HWA), an invasive insect killing native hemlocks in eastern North America, was undertaken to determine possible influences of the public’s desire and ability to help with invasive species prevention and control. All of the articles mention at least one of the following: HWA impacts to ecosystems (55.2%), hemlock characteristics (47%), and the value of hemlocks (38.8%). Articles that mention HWA impacts and hemlock value also mention associated topics such as subsequent impacts from hemlock loss to shade and temperature control of forests and streams, trout and recreational fishing, and the importance of hemlocks as a keystone species. 22.4% of articles provide advice or contact information for citizens to report HWA infestations or get involved in outreach programs, or to help educate readers about how to prevent further HWA spread and introductions. Informing citizens about HWA invasions can be useful to detect early infestations, range, and spread, and to coordinate control. This allows transparency as well as education and community participation in management, reducing negative impacts.
