Restoring the Wiliwili Forest of Waikoloa by Jen Lawson, Waikoloa Dry Forest Initiative Restoring the Wiliwili Forest of Waikoloa by Jen Lawson, Waikoloa Dry Forest Initiative Waikoloa Village on Hawai‘i Island was built in an area that was once a native Ha- waiian tropical dryland forest, one of the most biologically diverse and beautiful eco- systems of our islands. Not that a casual ob- server would know that looking at Waikoloa today. The lowland dry forests of the past have been almost completely lost, largely due to human activities, the introduction and ex- pansion of feral ungulates, invasive plant spe- cies and an increase in fire frequency. What is left is precious. Although fragmented and degraded, the areas of native forest that still persist are precious, beautiful and inspiring Wiliwili flower places and the wiliwili forest of Waikoloa is one of those amazing places worthy of preservation. In 2003 members of the Waikoloa Village community, that would later form the Waikoloa Dry For- est Initiative (WDFI), saw something startling happening in their community. Ancient wiliwili (Erythrina sandwicensis) trees were being removed from the native soil that had been their home for hundreds of years and being transplanted into the landscapes of wiliwili enthusiasts wealthy enough to procure one from the wild. The small group of citizen stewards was effective in preventing the removal and sale of any more wiliwili trees in the area and also began a movement to change the future of the landscape in Waikoloa. Today WDFI manages the Waikoloa Dry Forest Preserve which protects nearly 300 acres of lowland dry forest including many of the wiliwili trees that remain in the area. The preserve is also home to another native leguminous trees, the uhiuhi (Mezonueron kavaiensis), which is federally listed as criti- cally endangered. The preserve protects these special trees and is also the site of ac- tive forest restoration which involves the Hi'ialo (Wiliwili Tree) growing and planting of about 35 different native dryland species some of which are also endangered species that rely on con- servation efforts like the preserve for sur- vival. With help from the Natural Resources Conservation Service and DLNR’s Forest Stewardship Program a perimeter fence was completed in 2011 to exclude goats, and other ungulates, from the preserve. Priori- ties include reducing fuels and invasive grasses and planting thousands of trees over 10-15 acres per year. Reforesting Waikoloa is challenging and expensive and depends on Uhiuhi Flowers. Photo: Josh McCullough the collaboration of many agencies and indi- viduals to be successful. Community out- reach and environmental education are cen- tral to the WDFI’s mission and an important part of the long-term sustainability of the forest. WDFI regularly hosts volunteer days and group visits, provides interpretive tours for visitors and also coordinates a program for children, the Waikoloa Future Foresters, which incorporates ecology, Hawaiian cul- ture and land stewardship in a hand-on, out- door setting. The challenges of dry forest conservation are many and there is always more work to Future foresters planting. be done, but reforestation is possible; it is necessary and the results of the efforts to reforest Waikoloa are promising. In just a few years of working in the preserve we see healthy thriving trees, native plants outcom- peting weeds and some of the rarest plants of the islands producing flowers and seeds and giving us hope for a future where a di- verse dryland forest can once again sustain itself.

  • Remnant Wiliwili Forest Habitat at Wailea 670, Maui, Hawai`I: II. Comments on the Draft Environmental Impact Statement
    SPECIAL REPORT Maui Ecosystems at Risk Remnant Wiliwili Forest Habitat at Wailea 670, Maui, Hawai`i: II. Comments On the Draft Environmental Impact Statement AUGUST 2010 Lee Altenberg, Ph.D. Associate Editor, BioSystems Journal (Elsevier) Kihei, Maui, Hawai`i 96753-7118 • telephone: 808.875.0745 • [email protected] • dynamics.org/Wailea670 Wiliwili Forest at Wailea 670: II. Comments on Draft EIS!Lee Altenberg Summary The proposed project represents the largest deliberate destruction of lowland Ha- waiian dry forest ecosystem to occur on Maui in decades. Lowland Hawaiian dry forest ecosystem is among the twenty most endangered ecosystems in the United States. The DEIS compares this remnant with other remnants only to denigrate its conservation value and justify the proposed destruction of some 72% of this rem- nant, and severe fragmentation of another 14%. But it is silent on the importance of large, unfragmented habitat for conservation of biodiversity, and the fact that the project contains about the fourth largest of eight remaining large contiguous rem- nants of lowland dry forest on Maui. Moreover, the remnant is some 4 miles from Pu`u O Kali, which contains a number of listed endangered plant species, and it is likely that it could serve as critical habitat in their recovery. All of these eight rem- nants of this endangered ecosystem should be preserved and dedicated to restora- tion efforts. General Comments Lowland Hawaiian dry forest is an endangered ecosystem. Government and private ac- tions have allowed this ecosystem to be reduced to amounts and states of degradation that threaten its long-term existence.

    1 Erythrina sandwicensis Demography and Spatial Patterns of Erythrina gall wasp, Quadratichus erythrinae Infestation in Waikoloa, Hawai‘i Couch, C.S., J.S. Simonis, R.Q. Thomas, M. Manuel, D. Faucette, J.P. Sparks Abstract: Hawai‘i’s tropical dry forests are unique and highly endangered ecosystems that are currently being degraded by human development and invasive species. The Wiliwili tree, Erythrina sandwicensis (Fabaceae), a dominant species in Hawaiian tropical dry forests is now critically threatened due to the destructive impacts of invasive species, in particular the Erythrina gall wasp, Quadratichus erythrinae (Hymenoptera: Eulophidae). Here, we investigated the spatial and size distribution patterns of E. sandwicensis and potential effects of Q. erythrinae on population demographics by surveying a 310 ha parcel of dry forest in Waikoloa, Hawai‘i. This population of E. sandwicensis is comprised of 119 live trees, all of which are large adults that were spatially clumped to a radius of 400 meters.. In addition, the level of infestation of individual trees by Q. erythrinae was highly spatially autocorrelated, with the greatest correlation occurring within 100 m. Individual trees with higher gall wasp infestation had less tree leaf cover and a lower probability of seeds being present. The results of this study demonstrate that the largest population of E. sandwicensis on Hawai‘i is currently threatened by an invasive insect that alters the ability of trees to photosynthesize and decreases reproductive output. The clumped distribution of individuals likely facilitates the spread of the gall wasp but may allow for spatially focused conservation efforts. Thus a greater understanding of the severity of 2 invasive species impacts on plant physiology and reproductive fitness is necessary for the proper management of E.

Both of the new Lasioglossum species are relatively recent arrivals, but their precise date of introduction is not known because the alien Lasioglossum are often ignored by collectors and are poorly represented in collections. it had been assumed that all were L. impavidum (Sandhouse, 1924), which has been present in the islands since at least 1957 (Beardsley 1958, Beardsley 1959). A recent survey of o‘ahu lowland disturbed sites by Sd found three distinct species – L. impavidum , L. imbrex Gibbs, 2010, and L. microlepoides (ellis, 1914) – prompting a review of earlier specimens. Unless otherwise noted, specimens listed below were collected by KNM; specimens are deposited at the Bishop Museum (BPBM) and University of Hawai‘i–Mānoa insect Museum (UHiM).

  • Auwahi: Ethnobotany of a Hawaiian Dryland Forest
    AUWAHI: ETHNOBOTANY OF A HAWAIIAN DRYLAND FOREST. A. C. Medeiros1, C.F. Davenport2, and C.G. Chimera1 1. U.S. Geological Survey, Biological Resources Division, Haleakala Field Station, P.O. Box 369, Makawao, HI 96768 2. Social Sciences Department, Maui Community College, 310 Ka’ahumanu Ave., Kahului, HI 96732 ABSTRACT Auwahi district on East Maui extends from sea level to about 6800 feet (1790 meters) elevation at the southwest rift of leeward Haleakal¯a volcano. In botanical references, Auwahi currently refers to a centrally located, fairly large (5400 acres) stand of diverse dry forest at 3000-5000 feet (915- 1525 meters) elevation surrounded by less diverse forest and more open-statured shrubland on lava. Auwahi contains high native tree diversity with 50 dryland species, many with extremely hard, durable, and heavy wood. To early Hawaiians, forests like Auwahi must have seemed an invaluable source of unique natural materials, especially the wide variety of woods for tool making for agriculture and fishing, canoe building, kapa making, and weapons. Of the 50 species of native trees at Auwahi, 19 species (38%) are known to have been used for medicine, 13 species (26%) for tool-making, 13 species (26%) for canoe building 13 species (26%) for house building, 8 species (16%) for tools for making kapa, 8 species (16%) for weapons 8 species (16%) for fishing, 8 species (16%) for dyes, and 7 species (14 %) for religious purposes. Other miscellaneous uses include edible fruits or seeds, bird lime, cordage, a fish narcotizing agent, firewood, a source of "fireworks", recreation, scenting agents, poi boards, and h¯olua sled construction.

The adult male wasp, not shown, measures 1.0 mm. Introduction. Samples of gall-damaged leaves and stems of the coral tree, Erythrina variegata L., were first collected in Manoa, Oahu, on April 19, 2005, by a University of Hawaii graduate student. The galls were found to have been induced by the larvae of a tiny wasp which was subsequently identified as the erythrina gall wasp (EGW), Quadrastichus erythrinae Kim (family Eulophidae) by J.

Wailea 670 contains most of the 4th largest contiguous area of remaining wiliwili (Erythrina sandwicensis) habitat on Maui, approximately 110 acres in the southern 1/6 of the property. The oldest wiliwili trees are estimated to be hundreds of years old. 95% of the wiliwili ecosystem in Hawaii has already been destroyed, and survival of this ecosystem requires the preservation of the largest remaining vestiges. The de- veloper's current mitigation plan would set aside 6 - 20 of the 110 acres for preserva- tion (82%-95% destruction of the habitat area). The lower elevation portion of this habitat has already been destroyed by the development of the Makena Golf Course and Palauea.
