Primary purposes were to continue control of invasive orange hawkweed on Camp Island, Canada thistle on Garden Island, and oxeye daisy at Refuge Headquarters; to conduct invasive plant survey and outreach operations in coastal areas in and adjacent to the Refuge; and to discuss the status of the Refuge's program of invasive plant management at the 9th Annual Alaska Noxious & Invasive Plants Management Workshop.

Results from continued monitoring of hawkweed response at Camp Island, Karluk Lake, indicated that hawkweed frequency, a measure of plant distribution, declined from 78 to 33% over four years following a total of nine applications of clopyralid-based herbicide (Transline®). Since 2005, native herbs have continued to dominate ground cover on meadow sites formerly infested by hawkweed, as revealed by photo retakes. Following the initial treatment, most hawkweed growth has consisted of seedlings and young plants, which apparently germinated from the extensive pre-treatment seed pool. Prior to the 2008 treatment in June, the infestation site was re-surveyed, cleared of previous years' growth of non-target vegetation, and marked with biodegradable flagging. During mid summer, infestation sites were visited twice and hawkweed flowers were removed. Consistent with previous years, a second herbicide application occurred in early September. We continued implementation of IPM plans approved in 2007 for management of Canada thistle and oxeye daisy. Monitoring data collected in August 2008 results indicated that a fall 2007 application of Milestone®VM reduced thistle density (stems/m2) by 95%. Milestone®VM also was applied to manage oxeye daisy. Although both June and September treatments substantially reduced cover (%) of daisy, as indicated by monitoring results, observational evidence indicated that the September treatment was most effective (>95% reduction in daisy cover). As with hawkweed, we systematically removed flowers of plants apparently missed by treatments during mid summer. The Refuge partnered with local volunteers and the Kodiak Soil and Water Conservation District on three major outreach actions. Two of these consisted of reconnaissance surveys and outreach at remote settlements, most of which were lodges and base camps of commercial salmon fishermen, along the coast in and adjacent to the refuge (Olga Bay, Uganik Bay). Collectively, field crews visited 63 sites and contacted and exchanged information with 54 parties. Of the four relatively small infestations of invasive plants observed, three were found on the refuge and one was found on land adjacent to the Refuge. Species included orange hawkweed, oxeye daisy, creeping buttercup (Ranunculus repens), common tansy (Chysanthemum uliginosum), and purple foxglove (Digitalis purpurea). In concert with landowners and the District, the Refuge will plan and institute control of these populations over the next two years. Lessons learned and successes achieved in Kodiak were presented to participants of the 9th Annual Alaska Noxious and Invasive Plants Management Workshop in October 2008. Actions undertaken included: giving a talk on presentation on orange hawkweed management on Alaska NWRs, participating in a panel discussion on Canada thistle control efforts in Alaska, and poster presentation of hawkweed control efforts at Camp Island.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
Continue support for this highly important funding initiative. Since Kodiak Refuge has not been provided base funding to support its invasive plant management, it depends almost entirely on the funding support provided under this initiative.
