Â鶹´«Ã½<\/span>\u2019s isolated and unique island ecosystem makes the state especially vulnerable to invasive species, which can cause major damage to the environment, agriculture and public health. That is why federal, state and private funders are turning to the University of Â鶹´«Ã½<\/span> for solutions.<\/p>\n

UH<\/abbr> researchers are currently leading 98 grant-funded projects totaling more than $33.5 million to combat invasive species. The work targets some of the state\u2019s most urgent challenges, including rapid ʻōhiʻa<\/span> death, invasive mosquitoes that spread avian malaria, destructive food crop plant pests, invasive ants and beetles, and non-native plants and animals that damage forests and watersheds. Together, the projects aim to protect drinking water sources, food production, cultural resources and native ecosystems and species found nowhere else in the world.<\/p>\n

The funding includes 44 federal awards totaling $21,050,427 and 54 non-federal awards totaling $12,494,933. Projects are led by researchers at UH<\/abbr> Mānoa<\/span> and UH<\/abbr> Hilo and involve partnerships with national and state agencies.<\/p>\n

“These awards reflect the trust that agencies have in UH<\/abbr> to protect Â鶹´«Ã½<\/span>\u2019s people, environment and economy,” said UH<\/abbr> Interim Vice President for Research and Innovation Chad Walton. “You can see the damage coconut rhinoceros beetles leave behind, or how native birds are being wiped out by multiple invasive threats. Our UH<\/abbr> teams are conducting research to develop practical solutions that protect both our environment and our communities.”<\/p>\n

Protecting birds, forests, farms, communities<\/h2>\n

Several large projects focus on protecting native forest birds by reducing populations of invasive mosquitoes that carry avian malaria. Others use satellite imagery and remote sensing (technology that gathers data from aircraft or space) to track forest health and detect invasive plants early, when they are easier and less expensive to control.<\/p>\n

Researchers are also developing new molecular diagnostic tools—lab methods that use DNA<\/abbr> to identify species—to quickly detect fruit flies, moths and plant pathogens that threaten local farms. Additional projects support fencing and removal efforts to keep invasive animals out of sensitive ecosystems, as well as testing new pest control tools that reduce reliance on traditional insecticides.<\/p>\n
