Summary
This report describes the work performed by the Alaska Exotic Plant Management Team at Yukon-Charley Rivers National Preserve and Gates of the Arctic National Park & Preserve during the 2011 season including objectives, methods, and major conclusions. This field work is a continuation of work done by the Alaska Exotic Plant Management Team in the summer of 2010. The 2011 season was divided into four main regions from highest to lowest priority: Coal Creek Camp; Slaven’s Roadhouse; the Dalton Highway south of Coldfoot, AK; and Gates of the Arctic National Park & Preserve along the Middle Fork of the Koyukuk River. The main area of focus during the 2011 season was the high traffic areas along Coal Creek; a tributary of the Yukon River [...]
Summary
This report describes the work performed by the Alaska Exotic Plant Management Team at Yukon-Charley Rivers National Preserve and Gates of the Arctic National Park & Preserve during the 2011 season including objectives, methods, and major conclusions. This field work is a continuation of work done by the Alaska Exotic Plant Management Team in the summer of 2010. The 2011 season was divided into four main regions from highest to lowest priority: Coal Creek Camp; Slaven’s Roadhouse; the Dalton Highway south of Coldfoot, AK; and Gates of the Arctic National Park & Preserve along the Middle Fork of the Koyukuk River. The main area of focus during the 2011 season was the high traffic areas along Coal Creek; a tributary of the Yukon River downriver from Eagle, Alaska. Invasive plant infestations were recorded using a 2008 Trimble GeoXH Global Positioning System unit. Data was edited and analyzed using Trimble Pathfinder Office and ESRI ArcGIS. A total of 1.896 acres were surveyed, 1.896 acres of invasive plant infestations were mapped, and 1.307 infested acres were treated during the 2011 season. Invasive plant infestations were recorded in both remote and high traffic areas, however proper plant identification was difficult in the early part of June due to late phenology. During the 2011 field season one new species was discovered, sticky chickweed (Cerastiumglomeratum), which was found along the north side of Slaven’s Roadhouse. Additional personnel will be required in future years to manually treat multiple sites in the Coal Creek area.
