Melilotus albus (white sweetclover) has invaded Alaskan glacial river floodplains. We measured cover and density of plant species and environmental variables along transects perpendicular to the Nenana, Matanuska, and Stikine Rivers to study interactions between M. albus and other plant species and to characterize the environment where it establishes. Melilotus albus was a pioneer species on recently disturbed sites and did not persist into closed canopy forests. The relationships between M. albus cover and density and other species were site-specific. Melilotus albus was negatively correlated with native species Elaeagnus commutata at the Nenana River, but not at the Matanuska River. Melilotus albus was positively...
The article discusses adaptive management as a learning by doing management actions that allows managers to recognize which tools and strategies worked and which did not in a systematic manner. Adaptive management is an ongoing process that incorporates management objectives, monitoring and analysis of data and iteratively improves the results of management actions. Adaptive management can be made more powerful by incorporating Ecologically Based Invasive Plant Management (EBIPM).

This report describes the work performed by the Alaska Exotic Plant Management Team at Denali National Park & Preserve during the 2010 field season. The Exotic Plant Management Team staff at Denali National Park & Preserve was comprised of two American Recovery and Reinvestment Act funded Student Conservation Association interns and one seasonal National Park Service employee. For the seventh consecutive year, invasive plant inventory and control occurred within the park focusing on the entrance area including the Denali Park Road, Visitor Center, railroad station, and campground. Invasive plant infestations were mapped using a Trimble 2003 GeoXT and manual weeding was performed with the help of three Southeast...

Northern pike (Esox lucius) were introduced to the northern Susitna Basin of south-central Alaska in the 1950's, and have since spread throughout the upper Cook Inlet Basin. It is hypothesized here that invasive pike remodel the ecology of lakes in this region by removing vulnerable prey types. Trends in invasive diet suggest that pike switch to macroinvertebrate prey as fish prey are eliminated. Impacts of pike introduction were studied in detail for one species of resident fish, the threespine stickleback ( Gasterosteus aculeatus) to test hypotheses that invasive pike predation both reduces stickleback abundance and drives evolution of trophic and armor morphology in surviving populations. Stickleback abundance...

Alaska is vulnerable to a variety of changes causing by a warming climate. Alaska is no longer thought to be immune to wide scale invasive plant species infestations. Planning tools are needed to anticipate area of potential change and to identify invasive species of concern. I conducted a field study to determine presence or absence of any non-native vascular plant species per 100 m of transect keyed to vegetation type, canopy cover class, aspect, visitor use level, and use intensity on all major trails on and near Forest Service lands on the Kenai Peninsula, Alaska. Trailheads are thought to be sites of non-native species introduction to trail systems. Little is known about the number of introductions needed to...

Sweetclover (Melilotus alba) is a non-native legume that has formed dense and extensive patches along several rivers in Alaska. Our research objective was to determine if sweetclover impacts recruitment of native seedlings in floodplain habitats. To determine if sweetclover impacted recruitment, we conducted a removal experiment along two rivers in interior Alaska. When compared to areas where sweetclover was removed, areas with sweetclover had approximately 50% greater mortality of native seedlings, 25% less recruiting species, and a significant reduction in the quantity of light available to seedlings on floodplain surfaces. To determine if sweetclover shading was a mechanism that limited seedling recruitment,...
