This report describes the work performed by the Alaska Exotic Plant Management Team at Yukon-Charley Rivers National Preserve and Gates of the Arctic National Park & Preserve during the 2011 season including objectives, methods, and major conclusions. This field work is a continuation of work done by the Alaska Exotic Plant Management Team in the summer of 2010. The 2011 season was divided into four main regions from highest to lowest priority: Coal Creek Camp; Slaven’s Roadhouse; the Dalton Highway south of Coldfoot, AK; and Gates of the Arctic National Park & Preserve along the Middle Fork of the Koyukuk River. The main area of focus during the 2011 season was the high traffic areas along Coal Creek; a tributary...

Invasive species are a concern worldwide as they can displace native species, reduce biodiversity, and disrupt ecological processes. European bird cherry (Prunus padus) (EBC) is an invasive ornamental tree that is rapidly spreading and possibly displacing native trees along streams in parts of urban Alaska. The objectives of this study were to: 1) map the current distribution of EBC along two Anchorage streams, Campbell and Chester creeks, and 2) determine the effects of EBC on selected ecological processes linked to stream salmon food webs. Data from the 2009 and 2010 field seasons showed: EBC was widely distributed along Campbell and Chester creeks; EBC leaf litter in streams broke down rapidly and supported similar...
The ambermarked birch leafminer (AMBLM) (Profenusa thomsoni ) is an invasive leafminer native to the Palearctic from the United Kingdom to Turkey to Japan. It was introduced to the eastern United States in 1921 and has since spread to the mid-western U.S. states and Canadian provinces. This leafminer was introduced to Alaska in 1996, where it has since spread over 140,000 acres, from Haines to Fairbanks. The most severe damage is found throughout the Anchorage bowl, which extends south to Girdwood and North to Wasilla. The damage caused by P. thomsoni can be severe, defoliating entire trees. In 2006, it was noted that urban areas in Alaska experienced higher densities of AMBLM leafminer than adjacent forested areas....

Boundary organizations serve multiple roles in linking science and decision making, including brokering knowledge, supporting local- and cross-level networks, facilitating the co-production of knowledge, and negotiating conflict. Yet they face several challenges in providing services for an ever-increasing number of actors and institutions interested in climate information and adaptation. This study evaluates how the Alaska Center for Climate Assessment and Policy (ACCAP) innovated its boundary spanning role to improve outcomes by partnering with other boundary organizations through its ongoing climate webinar series. We utilize the concept of boundary chains to investigate outcomes associated with different extended...

Wrangell-St. Elias National Park and Preserve is the largest park in the National Park system. It covers more than 13 million acres and is part of the largest protected ecosystem on the planet. This report, written by Lil Gilmore, Biological Technician for the Park/Preserve, and David Goldsmith, an intern from the Chicago Botanic Garden, describes the 2007 Invasive Plant Management Program. David Goldsmith prepared the GIS maps found in Appendix A. The report was reviewed by Whitney Rapp, Exotic Plant Program Manager for Kenai Fjords National Park, and reviewed and edited by Mary Beth Cook, botanist for Wrangell-St. Elias National Park and Preserve.

The distribution of exotic plants and site factors influencing their abundance on roads and trails were studied in Wrangell-St. Elias National Park and Preserve during the summer of 2003. Seventeen species of exotic plants were found in the park at 173 locations. The most common species (Taraxacum officinale, Plantago major) were present at all study sites, while some (Trifolium spp., Bromus inermis, Leucanthemum vulgare) were restricted to specific disturbance types and particular areas. Though sampling was limited to areas in which exotic plants were growing, percent cover of exotics was not a significant component of sample sites, and exotic species richness was low at all sampling locations at 1.42 species per...

Invasive species pose a significant threat to forested ecosystems. Within the past 10 years, three nonnative birch leaf mining sawflies have been found in Alaska: Fenusa pumila, Heterarthrus nemoratus, and Profenusa thomsoni. Damage, caused primarily by P. thomsoni, is particularly notable in urban areas where the impact of browning tree crowns in mid-to-late summer raises public concern. The initial outbreak in Anchorage in 1996 increased to more than 32,000 ac by 2003. That same year, a survey was initiated to determine the extent of leaf mining sawflies throughout most of the state. Adult emergence, flight period, and larval phenology were assessed also. Surveys done through 2006 show that P. thomsoni is present...
