Building a New Community of Practice

Ecosystems in the Pacific Islands are being transformed by two large-scale, interacting threats: invasive species and climate change. PI-CASC has joined with the entities below to explore perspectives, needs, and research related to the confluence of invasive species management and climate adaptation in our region:

  • Commonwealth of the Northern Mariana Islands (CNMI) Division of Fish and Wildlife
  • CNMI Department of Lands and Natural Resources
  • Coordinating Group on Alien Pest Species (CGAPS)
  • East-West Center
  • Guam Department of Agriculture
  • Hawaiʻi Invasive Species Council
  • Micronesia Regional Invasive Species Council
  • University of Guam
  • U.S. Fish and Wildlife Service 

To learn more about the unique climate change and invasive species challenges our partners face across the Hawai’i and U.S.-Affiliated Pacific Islands region, please check out our 6 short videos recently premiered at the 2021 IUCN World Conservation Congress in Marseilles, France.

When Invasive Species & Climate Change Intersect: Survey of Hawaiʻi Natural Resource Managers

Title page of the report with a photo of man setting up fence in mountains.

This report summarizes the findings from a survey of natural resource managers in Hawaiʻi to establish a baseline assessment of concern about the influence of climate change on invasive species management, compare their access to and understanding of existing downscaled climate information for the state, and identify barriers to success in incorporating climate change into management practices.

The Pacific RISCC is using the survey results to identify tailored research opportunities on these two drivers of ecosystem change that will aid in the development and implementation of climate-adaptive management practices in Hawaiʻi and the US Affiliated Pacific Islands (USAPI) region.

Our Objectives

  • Identify priority lines of research, informed by managers, to examine the interactions between invasive species and climate change
  • Develop management strategies and actions to these combined threats while strengthening existing, successful approaches
  • Create a space for engagement and communication of lessons learned
  • Facilitate a network of resource managers, researchers, and interested community members and organizations
  • Promote relevant research and develop effective information-sharing strategies

2021 Action Items:

(A) Consolidate existing information and products at the invasives/climate nexus into one centralized/accessible location. Compile relevant peer-reviewed articles, technical reports, tools, and other resources on this website.

(B) Continue the webinar series and engage in other conferences/workshops as available. Potential topics include, but are not limited to: better understanding of uncertainty and information on potential range shifting species, native community resilience, effects and nature of extreme events, new introduction pathways, and impacts of seasonal changes.

(C) Create the needed organizational framework to facilitate discussions and set priorities at the invasives/climate nexus and move this effort forward in Hawaiʻi and the USAPI. This includes finalizing our core team and science advisory board.

(D) Strategically plan next steps, identifying/prioritizing needs/gaps, and determining where the most value can be added.

(E) Collaboratively-developed research agendas for the Pacific Islands region, which has different native biotas, divergent climate change projections, and a range of invasive species threats.

(F) Research summaries for managers to use in developing adaptive management programs.

Our Core Team

Portrait of Chelsea Arnott on top of mountain.Chelsea Arnott is a planner for the Hawaiʻi Invasive Species Council, where her work focuses on invasive plants and interagency biosecurity. She has diverse, island-wide invasive species management experience, from field to policy-level, working with the Coordinating Group on Alien Pest Species, Koʻolau Mountains Watershed Partnership, Oʻahu Invasive Species Committtee, and the Nā Ala Hele Program. Chelsea holds a Master’s degree in natural resources and environmental management from the University of Hawaiʻi at Mānoa, where she worked on plant nursery and import regulation proposals. 

Headshot of Laura Brewington at homeDr. Laura Brewington, a Research Fellow at the East-West Center, is Lead Investigator of the Pacific Islands Climate, Health, and Migration project, and an investigator for the Pacific Regional Integrated Sciences and Assessments (RISA) program. She designs and conducts collaborative, policy-oriented research using spatial analytical tools to support climate adaptation in Pacific Islands. She represents the East-West Center on the Pacific Invasives Partnership, focused on international biosecurity and natural resources management. She earned her Ph.D. in geography from the University of North Carolina–Chapel Hill based on research in agriculture, invasive species, and conservation in the Galapagos Islands.

Dr. Jeff Burgett is committed to protecting the irreplaceable natural heritage of the Pacific Islands for the future. He has worked in conservation and ecology in Hawai‘i, New Zealand, Panama, and American Sāmoa, and believes that informed, bold action is needed to make conservation successful in the face of climate change. Jeff is employed by the U.S. Fish and Wildlife Service as Science Applications Science Coordinator. He works on a range of projects including climate change, invasive species and diseases, and coral reef restoration. He has a Master’s degree from the University of Auckland and a Ph.D. from the University of Hawaiʻi in zoology. 

Portrait of Glen Dulla

Dr. Glenn Dulla, the Invasive Species Coordinator for the Guam Department of Agriculture-Biosecurity Division, is the principal investigator for federally funded invasive species management programs at Guam’s ports of entry. He also manages the administrative functions of the Guam Invasive Species Council. He represents Guam at the Pacific Plant Protection Organization wherein Guam is the current chair. He earned his Ph.D. in microbiology from the University of California–Berkeley based on research in genetic regulatory networks of pathogenic traits in plant-associated bacteria and their interactions with biotic and abiotic inputs.

Portrait of Bradley Eichelberger in front of sidewalkBradley Eichelberger is the Chief Geographic Information Officer at the Commonwealth of the Northern Mariana Islands’ Division of Fish and Wildlife.  His work is focused on the spatial ecology of threatened and endangered species, remote sensing applications to detect spatiotemporal changes in land cover, long-term monitoring of wildlife populations, and climate change vulnerability assessments for species of greatest concern.  Bradley has a Master’s degree in applied ecology and conservation biology from Frostburg State University, where he worked on modelling the distribution and habitat associations of rare plants.
