Pacific Island societies value, depend on, and actively manage terrestrial and marine ecosystems for the multiple benefits they provide, including those associated with plant and animal abundance, resilience to natural disasters, and the flow of water, soil, and nutrients. New ecosystem service models developed for Pacific Island landscapes now integrate land-to-sea connections, allowing us to assess how land-based management actions and threats (e.g. changes to climate and land cover) affect ecosystem benefits, from ridge to reef. Affecting actual change on the ground, however, depends on how scientific information is accessed and used by managers and other decision makers who have the capacity to influence ecosystem...
The objective of this study is to produce a map of invasive fern populations across approximately 35,000 acres of forests in windward Moloka‘i and in windward Mauna Kahalawai, Maui. This will enable the Division of Forestry and Wildlife and partners to control incipient populations of these weeds efficiently and effectively. The Division of Forestry and Wildlife (DOFAW) has successfully completed and in some areas exceeded the grant deliverables. The data has shown that invasive Mulesfoot (AngEve) and Australian Tree Fern (SphCoo) are at manageable levels in the northeastern forests of Molokai and West Maui. However, immediate action will need to be taken to eliminate these incipient populations. This project was...
The Fish and Wildlife Service is collaborating with the State of Hawaii Division of Forestry and Wildlife to identify priorities for science data that would directly apply to improving management for species recovery and delisting. This State-Federal partnership has identified windward Molokai and Maui’s ecosystems as an opportunity to gather data that could greatly benefit conservation actions. Northeastern Moloka‘i and West Maui contains some of the most intact native forest in the entire archipelago, and dozens of listed species. Here, windwardfacing valleys and plateaus have been managed for decades to greatly suppress feral animal populations, however incipient populations of invasive ferns – Angiopteris evecta...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
