Disease index for the rust Puccinia psidii on ohia (Metrosideros polymorpha) in Hawaii
Illustrations help define the categories for this disease index for ohia rust and a field survey form is available for reporting Puccinia psidii rust disease (University of Hawaii).
Ohia rust pest advisory (HDOA)
A "new pest advisory" RE: ohia rust (Puccinia psidii), a rust which which affects the native Hawaiian forest tree ohia (Metrosideros polymorpha) and many other species in the myrtle family (Myrtaceae), was issued by the Hawaii Department of Agriculture. This rust has wide host range including eucalyptus, paperbark tree, guava, rose apple, allspice, jaboticaba, Surinam cherry, species of Eugenia, and others in the family Myrtaceae. In other parts of the world, the rust is referred to as eucalyptus rust or guava rust.

Ohia: backbone of Hawaii's terrestrial ecosystems and culture
A poster about the importance of ohia (Metrosideros polymorpha) in Hawaii's native forest was presented at at International Union of Forestry Research Organizations' Conference on Invasive Species in International Trade in May, 2008. (PDF size: 425Kb) (Also available as a tabloid-sized PDF [PDF size: 620Kb].) (Citation: Buermeyer, K., L. Loope, A.M. La Rosa, and R. Hauff. 2008.

Rust ruins rose apple; guardians fear for ohia
The importance of the threat of the so-called "ohia rust" to the future of Hawaii's native forest is highlighted in this December 2008 Maui News article written by Dr. Lloyd Loope for the Maui Invasive Species Committee's series "Kiai Moku" ("guarding the island").

Information about Metrosideros polymorpha--including details regarding plant, flower, and leaf characteristics; pests and diseases; growth requirements; and environment--is provided by Native Plants Hawaii.
How to plant a native Hawaiian garden
An instructional handbook on planting a native Hawaiian garden was prepared by Office of Environmental Quality Control to guide the establishment of native gardens in schools throughout Hawaii to stimulate the awareness and appreciation of Hawaii's rare and fragile environmental resources (1992).

Rust ruins rose apple; guardians fear for ohia
USGS scientist Lloyd Loope discusses the potential impacts of the pathogen Puccinia psidii on Hawaii's native forests. He says: "Enforcement of stringent Hawaii quarantine
regulations would seem to provide the only effective means of protecting our ohia forest. If we lose ohia, we lose our forest."

Trees dying off (Star Bulletin 8/24/2008)
A virulent fungus killing rose apple trees on Oahu may spread to ohia trees and other vulnerable native plants.
Self-feeding as a bad thing (Raising Islands Blog, 22 August 2007)
Invasive species like firetree (Myrica faya) and albizia Falcataria moluccana, which fix their own nitrogen, alter the characteristics of whole ecosystems. Bloggist Jan TenBruggencate reviews research on how "self-feeders" can facilitate the invasion of other alien species.
Finding hidden invaders in a Hawaiian rain forest
"By applying novel measurement techniques from a high-altitude aircraft, scientists detected two species of invading plants that are changing the ecology of rain forest near the Kilauea Volcano in the Hawaii Volcanoes National Park."
