Invasive species management for Katmai National Park & Preserve, Alagnak Wild River, and Aniakchak National Monument & Preserve: 2015 summary report

Armstrong MS and Tourville JC. 2015. Invasive species management for Katmai National Park & Preserve, Alagnak Wild River, and Aniakchak National Monument & Preserve: 2015 summary report. Natural Resource Report. NPS/SWAN/NRR—2015/1096. National Park Service. Fort Collins, Colorado

2015 marked the sixth season that the Alaska Exotic Plant Management Team protocol was followed throughout the season to survey and control invasive plants in Katmai National Park & Preserve (KATM). This year, field work focused on inventorying new sites and monitoring sites that had not been visited in several years. New sites included the Alagnak Wild River and Hamersley Lake, and massive expansions to previously surveyed areas included Grosvenor, Kukaklek, and Mirror Lakes, and Amalik and Hallo Bays. Informal visual surveys for Elodea were a top priority after its discovery was confirmed in Lake Hood, a primary hub for float plane traffic to and from Alaska’s parks. There was no evidence of any infestations of Elodea in KATM. Mechanical and chemical treatment was executed on large known infestations at Brooks Camp, the Valley of Ten Thousand Smokes Road, Lake Camp, Fure’s Cabin, Nonvianuk Ranger Cabin and administrative areas in King Salmon. Taraxacum officinale (common dandelion) at Fure’s Cabin and Rumex acetosella (sheep sorrel) at Lake Camp were treated with Milestone herbicide. Manual control continues to be the standard treatment at most sites in Katmai as it has proven successful for small infestations such as the cultural site at Brooks Camp. Compared to infestations found within the contiguous United States, Katmai National Park maintains the distinction of containing healthy, intact native ecosystems with very low levels of infiltration by invasive plants. Preventive measures like education and outreach, and monitoring of Katmai’s current and upcoming construction projects will be essential in preserving the health and native beauty of the park.
