Summary
This report describes the work performed by the Alaska Exotic Plant Management Team at Denali National Park & Preserve during the 2011 field season. The 2011 Exotic Plant Management Team at Denali National Park & Preserve comprised of two Student Conservation Association interns including one International SCA from Japan and one National Park Service employee. For the eighth consecutive year invasive plant inventory and control efforts were performed within the park. Efforts were focused on disturbed areas with high traffic use which consist of park entrance trails, park infrastructures, and areas along the Park Road corridor. Infestations of invasive plants were mapped using a Trimble 2005 GeoXT, and controlled using manual hand-pulling [...]
Summary
This report describes the work performed by the Alaska Exotic Plant Management Team at Denali National Park & Preserve during the 2011 field season. The 2011 Exotic Plant Management Team at Denali National Park & Preserve comprised of two Student Conservation Association interns including one International SCA from Japan and one National Park Service employee. For the eighth consecutive year invasive plant inventory and control efforts were performed within the park. Efforts were focused on disturbed areas with high traffic use which consist of park entrance trails, park infrastructures, and areas along the Park Road corridor. Infestations of invasive plants were mapped using a Trimble 2005 GeoXT, and controlled using manual hand-pulling techniques often with the help of park volunteers. Data was edited and analyzed using GPS Pathfinder Office and ArcGIS. The team mapped, vouchered, and verified two invasive plant species that were new to the DENA WRST data set. These species are black bindweed (Fallopia convolvulus) and hempnettle (Galeopsis bifida). Education and outreach initiatives were also undertaken within the park, most notable being labeling of planter boxes at the Teklanika rest stop and presentations given at park wide employee trainings. Total canopy acres controlled in 2011 (12.3) were slightly lower than in 2010 (16.711), due mainly to a reduction in the number of person hours and volunteer crews available for treatment efforts. A total of 290.592 acres of the park and 23.395 acres of non-park lands were surveyed in 2011.
