Project Overview A new Trichomyrmex ant was first observed at Midway Atoll in 2019 and has caused management concerns due to its impacts on wildlife, endangered plants, and infrastructure since its arrival. Researchers supported by this Pacific Islands CASC project will map the range of the ant and test the effectiveness of using pesticidal baits to eradicate this destructive and...

Project Overview Climate change is expected to change rainfall patterns on pacific islands like Hawaiʻi, but current global models lack the resolution to accurately predict local rainfall. Researchers supported by this Pacific Islands CASC project will use machine learning models and historical data to improve rainfall predictions and create detailed rainfall maps for Hawaiʻi that can be...

Project Overview Hawaiian honeycreepers face numerous threats related to sea level rise, increasing storm frequency, erosion and invasive species. These impacts can alter their habitat, making it unsuitable and detrimental to their already small populations. Researchers supported by this Pacific Islands CASC project will create additional populations of a Hawaiian honeycreeper species by...

Project Overview Palmyra Atoll National Wildlife Refuge (NWR) is a critical nesting site for seabirds in the central Pacific Ocean, with ecosystems that are regularly impacted by the El Niño Southern Oscillation (ENSO). Researchers supported by this Pacific Islands CASC project aim to understand how past ENSO-driven climate variability and human activities have affected vegetation and...

Project Overview As climate change intensifies, accurately forecasting regional flood, drought, and heat risks is critical for planning, but current global climate models lack the resolution needed for useful local predictions. Researchers supported by this Pacific Islands CASC project will use generative artificial intelligence (AI) to create high-resolution precipitation maps and flood...

Project Overview The James Campbell National Wildlife Refuge in Hawai’i provides important wetland habitats for four species of endangered waterbirds. However, due to invasive species and climate change impacts, these habitats are becoming unsuitable for the fledging and longevity of these birds. Researchers supported by this Pacific Islands CASC project will examine the effectiveness of...

Project Overview Restoring grass-dominated landscapes into resilient forested ecosystems is a key strategy for addressing the growing risk of wildfire Hawaiʻi. However, conventional afforestation efforts typically require regular maintenance due to the persistent invasion of grasses in planted areas. In collaboration with Native Hawaiian Organizations, researchers supported by this...

Project Overview Sea-level rise, stronger storms, and coral reef bleaching events occurring with climate change threaten infrastructure, livelihoods, and cultural practices in Hawai'i. Researchers supported by this Pacific Islands CASC project will integrate Indigenous Knowledge and scientific research to co-produce climate adaptation strategies and conservation guidance for the...

Project Overview Climate change is altering the timing of natural seasonal events (phenology). This is manifesting in many ways including altering patterns of bird migration between Molokaʻi and southcentral Alaska. Researchers supported by this Pacific Islands CASC project will combine Traditional Ecological Knowledge (TEK) and conventional science to track these phenological shifts...

Project Overview Atolls in the tropical Pacific and Indian Oceans are experiencing significant changes to their landscapes and biodiversity due to climate change. Researchers supported by this Pacific Islands CASC will use historical data to study a 50+ year window of change in both islet size and the occurrence of lizard species. This work will better inform lizard distribution in light...

Project Overview Guam’s forests are vital to the ecosystem and local communities, but they face threats from wildfires, water quality, and invasive species, among others. To restore these ecosystems, researchers supported by this Pacific Islands CASC project will research the roles of native plants by identifying their “functional traits,” and using that knowledge to select species for...

Invasive species have had devastating effects on Pacific Island biodiversity, ecosystem services, food, infrastructure, culture, and public health. Meanwhile, climate change is expected to worsen droughts and wildfires, increase storm severity, and raise the temperature, acidity, and sea level, all of which exacerbate invasive species issues and complicate management. Invasive species...
