KENAI: Intern Completes First Invasive Species Inventory
Alaska Region, August 26, 2005
Print Friendly Version
Sadie Purinton, a volunteer from New Hampshire, recently completed three months of systematically evaluating portions of Kenai National Wildlife Refuge for exotic plants. Exotic invasive species, both plant and animal, are one of the greatest threats facing national wildlife refuges across the Country and Alaska is not immune. The study was the first of its kind on Kenai and was designed to determine the existence and potential severity of invasive plants, primarily in the areas most impacted by people. The focus of the inventory included a 56 square mile area of trails, seismic and power lines, roads, and oil fields scattered across the 2 million acre Refuge. Twenty-one species of exotic plants were found, and 194 of the 208 random sites examined had at least one of these species. Sadie was surprised to find many of the invasives were species she knew from the East Coast like oxeye daisy, dandelion, plantain, and clover. This initial work will help the Refuge establish formal inventory and monitoring efforts as well as strategies for treating known problem areas and preventing spread into other sites.
