We continued cooperative action on prevention, outreach, and inventory with efforts focused in and around remote settlements, many of which were inholdings within the legislative boundary of the Refuge. Control operations were limited to manual methods at infestation sites where manual and herbicide methods had been jointly applied in the past. This limitation was due to the Service’s suspension of herbicide application on Alaska NWRs pending completion of NEPA process. In response, the Refuge initiated an environmental assessment to address its strategy of invasive plant management and NEPA requirements.

Results from continued monitoring of hawkweed response at Camp Island, Karluk Lake, indicated that hawkweed frequency, a measure of plant distribution, declined from 86% over five 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 measurements on permanent plots and 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. During mid to late summer, infestation sites were visited three times and hawkweed flowers were removed and destroyed. We continued implementation of IPM plans approved in 2007 for management of Canada thistle and oxeye daisy. Monitoring data collected in August 2009 indicated that applications of Milestone®VM in fall 2007 and 2008 reduced thistle density (stems/m2) by 97%. Milestone®VM also was applied to manage oxeye daisy. Although both June 2008 September 2007 and 2008 treatments of separate areas 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. The Refuge partnered with local volunteers and the District on three major outreach and survey actions. These consisted of reconnaissance surveys and outreach in and around remote settlements, most of which were lodges and base camps of commercial salmon fishermen, along the coast in and adjacent to the Refuge. Collectively, field crews visited 43 settlement sites including eight on Refuge land and 34 on adjacent private land. We noted that most infestations were small, less than 1/10th acre, while the largest may have covered an acre. We found nine species we regard as highly invasive including orange hawkweed, oxeye daisy, common tansy, Canada thistle, creeping buttercup, and reed canary grass, Bohemian knotweed, Siberian pea shrub, and European mountain ash. In concert with landowners and the District, the Refuge will plan and institute control of these populations over the next two years. Results of remote coastal outreach and survey missions were presented to participants of the 10th Annual Alaska Noxious and Invasive Plants Management Workshop in November 2009.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
Continue support at this level. Kodiak NWR has relied almost entirely on this program to support its invasive plant management efforts.
