Rapid ‘Ōhi‘a Death: A House on Fire (video)
After Dark at the Park, Hawaii Volcanoes National Park, 29 Sept 2015

Join research plant pathologist Lisa Keith of the Pacific Basin Agricultural Research Center, Flint Hughes, Research Ecologist with USDA Forest Service Institute of Pacific Islands Forestry and J.B. Friday, University of Hawaiʻi College of Tropical Agriculture and Human Resources as they provide an update on this new threat to Hawaii's native forests. Research so far has determined that within two to three years of detection, a majority of trees in some measured stands have succumbed to the disease. This means the fungus has the potential to threaten forests statewide, resembling not so much a tree disease as a house on fire. (1 hour)

Rapid ʻŌhiʻa Death ~ ʻŌhiʻa Wilt: Sampling ʻŌhiʻa trees for infection with Ceratocystis fimbriata: Two-minute video on how to take samples from ʻōhiʻa suspected of having Ceratocystis wilt or Rapid ʻŌhiʻa Death. Visit www.rapidohiadeath.org or www.ohiawilt.org for more information.

Rapid ʻŌhiʻa Death | Ceratocystis Wilt of ʻŌhiʻa: A newly identified disease has killed large numbers of mature ʻōhiʻa trees (Metrosideros polymorpha) in forests and residential areas of the Puna and Hilo Districts of Hawaiʻi Island. Pathogenicity tests conducted by the USDA Agriculture Research Service have determined that the causal agent of the disease is the vascular wilt fungus, Ceratocystis fimbriata.

FOREST STEWARDS 2014: CTAHR’s Forestry Extension program congratulates its third class of Forest Stewards. Despite delays due to Hurricane Iselle and cancellations due to impending lava flows, eleven participants successfully completed a 30-hour intensive training program held September 18th-21st at Kilauea Military Camp, in Hawai‘i Volcanoes National Park. Morning and evening sessions were taught by J.B. Friday (NREM, forestry), Clay Trauernicht (NREM, wildfire science), Faith Inman-Narahari (NREM, koa forestry) and other local experts. Participants, all of whom own or manage forest lands, learned about topics including Hawaiian culture and natural history, wildlife habitat, invasive species, forest management and protection, koa forestry, agroforestry, taxes, estate planning, and financial matters. Afternoon field trips to local managed private forests provided valuable experiences to balance the class sessions. The new graduates are committed to giving back to their local communities through activities such as hosting field days on their own property and other efforts to help landowners manage their forests.

A new brochure outlines the correct procedure for injecting albizia trees (Falcataria moluccana) with the herbicide Milestone (R) (active ingredient aminopyralid). The technique if for natural areas only and not residential areas. Do not use this technique on trees that may damage homes, buildings, or power lines when they fall.

Tree improvement includes better genetics for seedlings and better ways to grow, plant, and care for them. The Tropical Hardwood Tree Improvement and Regeneration Center is an effort by Hawaii and mainland foresters to do better at growing tropical hardwood trees, starting with koa. Check out the new website, www.TropHTIRC.org!
