| dc.description.abstract | The eastern hemlock (<i>Tsuga canadensis</i>) is a long-lived, shade-tolerant evergreen tree which grows throughout eastern North America, including within New River Gorge National Park and Preserve. Its dense foliage creates a dark, cool forest understory that supports a unique assemblage of plants, as well as facilitating exceptional stream habitat for fish species such as brook trout (<i>Salvelinus fontinalis</i>). However, eastern hemlocks face an ecological threat from several invasive pests, most notably the hemlock woolly adelgid (HWA; <i>Adelges tsugae</i>). This tiny insect feeds on the sugars produced by the hemlock tree, causing physiological stress that can kill in the tree in as few as four years, particularly when combined with other stressors such as drought. First detected in the southern West Virginia national parks in 2000, HWA is now common throughout hemlock ecosystems in the New River Gorge. While some mortality has occurred, the National Park Service utilizes a variety of tools to maintain ecological value and scenic enjoyment of hemlock forests in the park, including chemical treatments, biological control agents, and forest health monitoring. This poster will detail the park’s hemlock program over the past 25 years, providing data on monitoring trends, exploring emerging threats, and outlining future plans. | en |
