Invasive and exotic plant management in Klondike Gold Rush National Historical Park: 2018 summary report

Gould L. 2018. Invasive and exotic plant management in Klondike Gold Rush National Historical Park: 2018 summary report. Natural Resource Report. NPS/KLGO/NRR—2018/1821. National Park Service. Fort Collins, Colorado

Summer 2018 marked the Exotic Plant Management Team’s (EPMT) 15th year at Klondike Gold Rush National Historical Park (KLGO). The four main methods used by EPMT to prevent the propagation of invasive plants were: surveying new and old infestations, manual removal of infestations, restoring disturbed areas, and providing public outreach and education. It is important to monitor invasive species in order to track their spread and identify new infestations as they arise for rapid response treatment. Part of the EMPT’s work was to remap past infestations while surveying for new infestations. Using priority guidelines, EPMT helped manage multiple ongoing projects such as removing reed canary grass (Phalaris arundinacea) from Pullen Creek, pulling white sweet clover (Melilotus albus) from the municipal brush pile, pulling bird vetch (Vicia cracca) from the bus depot, and removing oxeye daisy (Leucanthemum vulgare) from locations along the Dyea Road. A new patch of Canada thistle (Cirsium arvense) was inventoried and removed near Pullen Pond. After encountering new orange hawkweed (Hieracium aurantacum) growth, the 2016 tarping project at the Lower Dewey Reservoir was monitored, repaired, and expanded over the 2018 season. Restoration conducted in 2017 after the reconstruction of the Dyea Townsite Road was revisted. The EPMT also took part in multiple outreach events to educate the public about invasive plant species. More than 350 pounds of invasive vegetation was removed this year including other notable species such as tall buttercup (Ranunculus acris), yellow toadflax (Linaria vulgaris), and narrowleaf hawksbeard (Crepis tectorum). In 2018, 6.91 acres were surveyed, 0.28 acres were infested and 0.17 acres were treated.
