[spoiler open=”No” title=”Statewide Public Outreach Program” icon=”chevron”] Hawai’i Invasive Species Council, $312,000

A statewide outreach program is sought in cooperation with the public and private sector and targets both visitors and residents to increase voluntary compliance of quarantine laws, avoid accidental introductions of invasive species, and maintaining an effective pest hotline reporting system that delivers timely information to managers on the ground. This has been accomplished by establishing three public outreach specialist positions to carry out these tasks. A public notice of request for proposals will be made so as to repeat a successful small grant program designed to support community based public outreach that supports HISC goals. A rewrite and reprint of the CGAPS 1996 brochure- “The Silent Invasion” will be partially funded by the materials budget- the remainder is to support any media projects undertaken by staff during the year. Also included is the stipend for two Americorp interns which will be matched with Americorps funds. This previously included projects from a broad array of organizations and community groups, individuals and staff.


  1. Outreach staff, project support: $189,000
  2. Materials: $60,000
  3. Requests for proposals: $50,000
  4. Stipends Americorps: $13,000[/su_spoiler]


HISC research and technology evaluation committees completed a review (late in 2007) of 48 research and technology proposals following request for proposals that attracted 12 coqui frog and 36 general invasive species proposals. A total of 21 reviewers looked at some or all of the proposals, including staff and experts from DOA, DEBDT, DOH, DLNR, HISC, USDA, UH, Bishop Museum, USGS etc. A core group met at the University on November 29, 2007 to review the top ranked projects.

[/su_spoiler] [spoiler open=”No” title=”Evaluating impact of Puccinia psidii rust strains on Ohi’a” icon=”chevron”] Hauff/DLNR Division of Forestry and Wildlife, $36,049

Summary: This project aims to document the impacts of a variety of strains of ohia rust on Ohi’a through tests carried out on a variety of Ohi’a types from Hawaii, but carried out in Brazil where it is believed that Ohi’a rust originates from.

Problem Statement:

In April 2005 a new disease was detected on ‘ōh‘ia seedlings in a nursery on O’ahu. The disease was eventually identified as Puccinia psidii Winter, known as guava or eucalyptus rust, but locally dubbed ‘ōh‘ia rust (Killgore and Heu). By August 2005 the disease had spread to all of the main Hawaiian Islands. The disease has a very broad host range of species in the Myrtaceae family (Simpson et al., 2006). Native to South America is can have significant impact on Myrtaceae species from Asia, Australia, and the Pacific islands where exposure to the disease has only recently occurred through introduced plantations of species such as eucalyptus.

In Hawai’i, the disease has been found on 23 different plant species growing in the environment (Robert Anderson, pers. comm.) including the native species Metrosideros polymorpha, Eugenia koolauensis, and E. reinwardtiana. The disease is causing dramatic defoliation of rose apple (Sygyzium jambos) throughout Hawai’i’s watersheds. The damage to other species is limited to small lesions and occasional stunting of shoots. Partial defoliation of Metrosideros polymorpha has been observed, but only sporadically.

There is strong evidence of host specialization of this pathogen with isolates from one host plant species not necessarily infecting other known host plant species (Glen et al., 2007). This existence of different disease strains is supported by observations of differing host ranges in areas where the disease is found. For example, Eucalyptus spp. are highly impacted in Brazil but eucalyptus trees in Hawai’i have not been found infected in the environment. Likewise, the allspice (Pimenta dioica) industry was wiped out in Caribbean Islands (MacLachlan, 1938), but the same species commonly planted in landscaping in Hawai’i has not been infected.

There is an enormous amount of concern among foresters and conservationists in Hawai’i that strains not yet introduced to Hawai’i could be more virulent on M. polymorpha (Loope and LaRosa, 2007). The importance of M. polymorpha to Hawaii’s forest ecosystems cannot be understated. The tree is dominant or co-dominant in 80% of Hawai’i’s remaining native forests and provides habitat for countless endangered birds, plants, and invertebrates. This matrix species also provides important watershed cover preventing erosion and allowing rainwater to percolate through the ground to aquifers that supply households, farmers, and industry with the water they need for survival.

In 2006, Dr. Shaobin Zhong with the University of Hawai’i’s College of Tropical Agriculture and Human Resources Plant and Environmental Protection Sciences program characterized 15 microsatellite markers on the genome of P. psidii that can be used to differentiate strains of the disease (Zhong et al., 2007). His preliminary work on 12 samples taken from Hawai’i’s forests showed the samples to be homogenous and similar to one of the samples sent from Florida. Further genetic analysis of samples collected on a comprehensive survey funded by the USDA Forest Service and carried out by UH researchers is scheduled for November 2007. This analysis will confirm whether Hawai’i only has one strain of the disease.

In August 2007, the Board of Agriculture passed an interim rule restricting entry into Hawai’i of plants and plant material in the Myrtaceae family coming from areas where Puccinia psidii is known to be present. Known hosts that were regularly imported into the state as green fillers for the florist industry include eucalyptus (Eucalyptus spp.), myrtle (Myrtus communis), and waxflower (Chamelaucium uncinatum), all of which were being imported from areas known to be infested. The interim rule is only in place for one year while a permanent rule is developed. There is a strong need for scientific knowledge supporting the adoption of a permanent rule. Specifically the state needs documentation of different genetic strains existing outside of Hawai’i and their potential impact to Hawai’i’s environment and economy.

The proposed project is to utilize Dr. Zhong’s preliminary work to analyze disease samples from Brazil, as well as places where it has been introduced such as Florida and California. The different strains distinguished by the genetic analysis will be used to inoculate ‘ōh‘ia seedlings in Brazil, and possibly Florida and California, to determine susceptibility. This will allow us to analyze the risk of ‘ōh‘ia becoming severely impacted by introduction of disease strains not yet present in Hawai’i.

[/su_spoiler] [spoiler open=”No” title=”Determining the efficacy of fungicide to protect endangered species from the rust Puccinia psidii” icon=”chevron”] Uchida/University of Hawai’i, $34,810

Summary: Trials to determine types and amount of fungicide needed to control Ohi’a rust on a small scale where it affects rare native species.

[/su_spoiler] [spoiler open=”No” title=”The effects of cooking on diphacinone residues in feral pig tissue” icon=”chevron”] Pitt/USDA APHIS WS, $31,050

Summary: This project aims to address concerns about the use of diphacinone containing baits as a rodenticide to reduce the harmful impacts of rodents on Hawai’i’s threatened and much depleted native flora fauna. Although strict rules are to be adopted limiting the hunting of pigs in areas treated with diphacinone – and it is known that pigs that eat the baits do not accumulate levels of the chemical that would pose a risk to human health. Via laboratory tests this study will accurately document the risks related to incidental consumption of pigs by humans where the pigs have eaten baits.
