Book Predicting Invasive Plant Species Range Expansion in Alaska

Download or read book Predicting Invasive Plant Species Range Expansion in Alaska written by Elizabeth Michelle Bella and published by . This book was released on 2009 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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 indentify 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 establish a non-native species in northern climates, or the expected distances a particular species can be expected to spread up a trail. Prediction of non-native species spread along Alaskan trails is possible by examining vegetation type and intensity of use, with greatest impacts in open types with high use. I used biogeoclimatic models to forecast potential vulnerabilities with respect to invasive species distribution in Alaska. I selected three invasive plant species of interest in Alaska with different current distribution (reed canarygrass, present and widespread; purple loosestrife, present and limited; and leafy spurge, not yet present but considered potentially invasive). Species were modeling using two different predictive models (BIOCLIM in the DIVA-GIS platform and MaxEnt), two different future climates (Hadley and CCC), two emissions scenarios (A2, high and B2, low), for current climate plus three time steps (2020, 2050, 2080). Models were assessed with 25% test data, and then trained with 75% of the data. MaxEnt models performed better than DIVA-GIS models. All models showed current potential range that exceeds their known occurrence. For each species, we compared area difference in predicted habitat suitability between scenarios and between time steps in both models as a quantified measure of potential habitat change. I applied the modeling procedure to an additional twenty-four species to create an atlas of scenario maps for Alaska. All models showed current potential range that exceeds their known occurrence"--Leaves ii-iii.

Book excerpt: During September 19-20, 2006, a conference was held at the University of Washington Botanic Gardens, Seattle, WA, with the title S2Meeting the challenge: invasive plants in Pacific Northwest Ecosystems. S3 The mission of the conference was to create strategies and partnerships to understand and manage invasions of non-native plants in the Pacific Northwest. The audience included over 180 professionals, students, and citizens from public and private organizations responsible for monitoring, studying, or managing non-native invasive plants. This proceedings includes twenty-seven papers based on oral presentations at the conference plus a synthesis paper that summarizes workshop themes, discussions, and related information. Topics include early detection and rapid response; control techniques, biology, and impacts; management approaches; distribution and mapping of invasive plants; and partnerships, education, and outreach.

Book Social Dimensions of Invasive Plant Management

Download or read book Social Dimensions of Invasive Plant Management written by Tara L. Callear and published by . This book was released on 2018 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uncertainty pervades attempts to identify an efficient management response to the threat of invasive plants. Sources of uncertainty include the paucity of data, measurement errors, variable invasiveness, and unpredictable impacts of the control methods. Rather than relying on this uncertain evidence from the natural sciences, land managers are taking a more participatory approach to invasive plant management to help alleviate risk and share the responsibility of implementation of proactive control and eradication strategies. This research is intended to contribute to this process of social learning by revealing the beliefs that determine stakeholder management preferences in a case study involving an infestation of Vicia cracca (bird vetch) affecting public lands, north of the Arctic Circle, along the Dalton Highway in Alaska. Possible encroachment of this “highly invasive” species upon vulnerable areas of high conservation significance in this rapidly changing, boreal-arctic system has motivated some stakeholders to advocate an aggressive, early response aimed at eradication using herbicides. This case study applies social-psychological theory in the study of the interactions between human behavior and human outcomes. Interior Alaska stakeholders were engaged in a survey to measure support for a scenario involving the use of herbicides to control the highly-invasive species, Vicia cracca (bird vetch), which has spread north along a road corridor north of the Arctic Circle. Respondents were asked a series of questions about the “likelihood” and “acceptability” of the possible outcomes. The survey results aligned with the expectation that attitudes predict management preference, however the beliefs that influence these attitudes were more complicated than expected. The results address the feedbacks anticipated between the human outcomes and human behavior in the social template within the broader system context that are critical to management success. The purpose is to utilize the results of this specific case study to facilitate the development of ongoing research questions that are generalizable to other affected boreal-arctic ecosystems, regionally and globally.

Book Invasive Plants and Pollination of Alaskan Berry Species

Download or read book Invasive Plants and Pollination of Alaskan Berry Species written by Katie Villano Spellman and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A rapidly changing climate and human disturbance patterns have accelerated the spread of invasive plants species in Alaska. Non-native plant invasions can disrupt pollinator services to native plants and have the potential to impact the pollination and fruit set in berry species important for subsistence harvest. My dissertation aims to address the dual need for greater understanding of the impacts of invasive plants on pollination of berry species in boreal ecosystems and the need for research on education strategies that best prepare Alaskans to respond to the issue. I integrate an ecological field experiment, a citizen science program where data is used to validate phenology models derived from heraium data, and an invasive plants education experiment testing the effects of a metacognitive learning intervention to provide multiple perspectives that inform the management of invasive plants in Alaska. The ecological field experiment found that invasive Melilotus albus acts as a magnet species for pollinators, which increased seed production in Vaccinium vitis-idaea, slightly decreased pollination in Rhododendron groenlandicum, and had no detectable interactions with Vaccinium uliginosum. The impact M. albus had on R. groenlandicum changed with distance from the invasive plant patch, but the impact on V. vitis-idaea did not. Using data from a statewide citizen science program monitoring the phenology of these species, I found that herbarium-based phenology models were valid for assessing relative shifts in phenology of these species across Alaska. Employing the research on M. albus and the berry species as a test case, I found that students who received the metacognitive learning intervention show long-term improvement in metacognitive skills compared to students in the control group, but that the groups did not differ in their ability to apply resilience thinking skills to the environmental problem-solving. I synthesized social-ecological resilience and education research to investigate how citizen science and metacognitive learning could contribute to the capacity of Alaskans to respond to social-ecological change. Together, the ecology and education research presented here provide diverse perspectives on how to best manage and build the human capacity to manage M. albus near subsistence plant species.
