Developing Tools for Restoring Natural Resources
Developing Tools for Restoring Natural Resources
Restoring ecosystems and preventing extinction in the Pacific Islands are two daunting tasks for land managers. With such large numbers of Threatened and Endangered species and the vast amount of land that has been degraded thus far, effective long-term restoration relies on large-scale ecological restoration of landscapes. PIERC researchers are involved in the adaptive management of a number of ecosystems throughout the Pacific Islands.

Conservation Ecology of the Mariana Swiftlet on Guam
Population counts of Mariana swiftlets is critical to understand if control of brown tree snakes in Guam have aided swiftlet recovery. USGS scientists and The University of Hawai’i at Hilo are testing videographic methods to count Mariana swiftlet population size and observe their nesting and roosting behavior.
Climatic and Ecological Scenarios to Guide Development of a Spatial Resist-Accept-Direct Portfolio at Nāpuʻu, Hawaiʻi
Climate change and invasive species are transforming ecosystems. The Resist-Accept-Direct (RAD) framework organizes management objectives into those that seek to Resist change and maintain historical ecological communities, those that Accept some or all aspects of ecological transformation, and those that Direct an ecological community to a preferred state. We are evaluating risks posed by climate...
Post Fire Restoration in Hawai‘i Volcanoes National Park
We are studying post-fire forest regeneration in montane habitats within Hawaiʻi Volcanoes National Park. By testing out different restoration strategies, as well as links between grass cover and fire, we hope to increase restored forest fire resistance and resilience.
Identifying Genetic Diversity of Wolbachia Bacteria for Mosquito Control
We are sequencing the DNA of Wolbachia bacteria found in mosquito populations in Hawai’i and those used for mosquito control. We are also developing sample processing techniques to increase the efficiency and accuracy of monitoring mosquito control efforts to help long-term survival and restoration of Hawaiian forest bird populations.
Developing Planting Designs for Forest Restoration
We are testing different planting mixtures and densities to refine restoration efforts in the Hakalau Forest National Wildlife Refuge.
Building Resilience to Invasive Species in Ohia Forests
ʻŌhiʻa ( Metrosideros polymorpha) is the dominant tree in Hawaiian forests, but Rapid ʻŌhiʻa Death (ROD), a newly emerging disease that stands to cause high mortality of this ecologically important tree, may lead to invasions by exotic plants as gaps open in the forest. To better understand if planting of ʻōhiʻa seedlings can be used as a restoration tool, we investigated the survival of ʻōhiʻa...
Disturbance Ecology, Geomorphology, and Plant Dynamics in Grass Invaded Sites, Hawai‘i
The Keamuku Maneuver Area (KMA) is a 9,227 ha. unit of Army Pohakuloa Training Area (PTA) on Hawai‘i Island. The Army’s mission at KMA is threatened by erosional processes that could make parts of the training area too hazardous or too degraded for sustained use. These processes depend on vegetation dynamics and the nature of the soils underlying KMA. Knowledge of the training area was...
