(Honolulu) – An aerial survey of some 20,000 acres of forest on O‘ahu has resulted in the fourth detection of Rapid ʻŌhiʻa Death (ROD) in an ʻōhiʻa in the Moanalua Section of the Honolulu Watershed Forest Reserve above Tripler Army Medical Center.
(Honolulu)- One of Hawaii’s most important native plants is the Naio tree. Naio has been widely planted in landscapes and is an important component of our island’s coastal ecosystems. A decade ago naio became threatened with a small invasive insect pest known as thrips found on Hawai’i Island. Thrips are narrow, dark brown to black and approximately 2.2.5 mm in size and are native to Tasmania. They were likely first accidentally introduced in the U.S. in California.
(Līhu‘e) - Recent helicopter surveys prompted foresters with the DLNR Division of Forestry and Wildlife (DOFAW) to sample 10 dead ‘ōhi‘a in two locations within the Līhu‘e-Kōloa Forest Reserve. Six trees tested positive for Ceratocystis lukuohia, the more virulent of the two fungal pathogens causing Rapid ʻŌhi‘a Death, the disease killing ‘ōhi‘a across the state.
(Lihue) – The population of Pacific Rats on tiny Lehua Island, off Kaua‘i’s west coast remains extremely low, two years after three applications of a rodenticide to clear them out of the State Seabird Sanctuary.
(Kahului) – In July, one of two species of fungus causing Rapid ʻŌhiʻa Death (ROD) was detected for the first time on Maui, in the Hāna region. The response was quick, and the tree, which was in an ornamental setting, was destroyed. However, surveys for the disease are ongoing.
(Honolulu) - One of the species of fungus causing Rapid ʻŌhiʻa Death (ROD) was recently detected for the first time on O`ahu. A team of natural resource managers from the O`ahu Invasive Species Committee (OISC) and the Ko’olau Mountain Watershed Partnership (KMWP) recently sampled a dead ʻōhiʻa tree on private land in a remote area in the Ko’olau Mountains above Pearl City.
(Honolulu) – When DLNR Chair Suzanne Case was alerted by the O‘ahu Invasive Species Committee (OISC) of their desire to do a miconia survey of her property, she readily agreed. Good news – no Miconia (an invasive, noxious weed), Bad news – naio thrips had infested an 18-year-old naio shrub.
(Honolulu)-The Rapid ʻŌhiʻa Death Working Group, formed to respond to a new disease threatening Hawai‘i’s most important native forest tree, recently received the Conservation Innovation award at the 2019 Hawaii Conservation Conference. The working group is made up of nearly 200 individuals representing state, county, federal, university, non-profit organizations, local and private businesses, as well as private citizens. The purpose of the Rapid ʻŌhiʻa Death Working Group is to facilitate inclusive communication on all issues related to the fungal disease and share knowledge on a regular basis among group members, their organizations, and the people of Hawai’i.
(Kahului, Maui) - Ceratocystis huliohia, the less aggressive strain of the fungal disease called Rapid ʻŌhiʻa Death was recently detected in a single tree on private property in East Maui. The lone ʻōhiʻa tree, 15-20 feet tall and eight-to-ten inches in diameter is located a few feet from a taro loi.
(Lahaina) – When a biologist who was looking for native snails noticed signs of caterpillars feeding on māmaki in Olowalu, he came across a new invasive species. It was a kind of caterpillar he had never seen before; the Arcte coerula (Ramie moth).
