The summer 2016 season was the Exotic Plant Management Team’s (EPMT) 13th year at Klondike Gold Rush National Historical Park (KGLO). The four main methods to prevent the spread of invasive plants around the park and the surrounding area were monitoring and mapping new and previous infestations, manually removing invasive species, restoring areas of disturbance, and providing education and outreach to the public. Monitoring invasive species is important to track progress and identify new or growing infestations. A portion of the work by the EMPT was remapping past infestations and surveying for new infestations. Depending on priority, EPMT then manually removed or treated invasive plants. In the Sheep Camp Restoration Project area, reed canary grass (Phalaris arundinacea) was manually pulled instead of chemically treated at Sheep Camp because of poor weather conditions. A tarping project to eradicate orange hawkweed (Hieracium aurantiacum) from its only known location in Skagway was implemented this year and will be monitored in following years. Other species of note that were removed this year were white sweet clover (Melilotus albus), oxeye daisy (Leucanthemum vulgare), ornamental jewelweed (Impatiens glandulifera), and tall buttercup (Ranunculus acris). Over 350lbs of invasive plants were removed during the 2016 summer season. This year, a construction project on the Dyea Townsite Road required EPMT team participation. Partnering with a restoration team, EPMT staff partnered with a restoration team to promote native plant regeneration and prevent invasive plants from colonizing the disturbed construction areas. The EPMT also planned and participated in many outreach opportunities to educate the public about the problems invasive species inflict on the environment.
