National Tropical Botanical Garden Staff
Chipper Wichman is NTBG's Chief Executive Officer and serves as Director of the organization, effective January 2005. Prior to serving as the organization's Acting Director for nearly 1-1/2 years, Mr. Wichman served as Director of NTBG's Limahuli Garden on Kaua`i since 1994 and also as Director of NTBG's Kahanu Garden on Maui from 1997 through early 2002.
Mr. Wichman joined the organization in 1976, graduating from its Horticultural Internship program. He spent his early career developing Limahuli Garden. During this time, he obtained a Special Subzone designation in the Conservation District for the entire Limahuli Valley, restored ancient taro terraces, developed a collection of rare and endangered native Hawaiian plants, opened the garden to educational tours, and added the 989-acre Limahuli Preserve. Subsequently Limahuli was named the Best Natural Botanical Garden in the United States by the American Horticultural Society.
Through numerous grants, Mr. Wichman was able to fund extensive native habitat restoration work in the Limahuli Preserve, which continues today. In addition to his work in conservation and education, he has lead efforts to perpetuate and preserve native Hawaiian culture. He spearheaded a four-year Indigenous Communities Mapping Initiative Project at Limahuli. This collaborative project focused on researching and documenting traditional cultural knowledge and land use relationships and perpetuating traditional practices within the native community.
Mr. Wichman brought renewed focus to NTBG's conservation and horticulture efforts, a greater appreciation of the native Hawaiian culture, and undertook a major capital campaign. Under his leadership, NTBG built its fourth building at the headquarters campus, a major research facility which has received wide attention for its "green architecture."

Dr. David Lorence occupies the B. Evans Chair of Botany and came to the National Tropical Botanical Garden in 1987. He is the Senior Research Botanist for the organization. Research specialties are systematic studies of tropical plants, floristics, and invasive plant species. His systematic research focuses on Pacific and neotropical members of the large and diverse Rubiaceae family, which includes coffee, quinine, and gardenias. He also studies the Monimiaceae family of the Malagasy region and tropical America.
Dr. Lorence's floristic research includes a multi-institutional collaboration on a "Vascular Flora of the Marquesas Islands," contributing partial treatment of the Rubiaceae for "Flora Mesoamericana," and participating in a project to develop an annotated checklist of the plants of Pohnpei and Kosrae. His research on invasive species includes restoration efforts targeting Hawaiian dryland forest and exotic species invasion in Mauritius wet forest communities. He has carried out extensive fieldwork in Hawaii, Samoa, the Marquesas, Micronesia, New Caledonia, Mexico, and the Malagasy region.
Dr. Lorence directs the research library and herbarium at headquarters, curates NTBG's collections of Rubiaceae and of Zingiberales, and serves on the board of the Heliconia Society International.
He is editor of Allertonia, NTBG's series of occasional papers.

Dr. Ragone was appointed Director of the Breadfruit Institute in 2003 and has worked at the National Tropical Botanical Garden since 1989. She is an authority on the conservation and use of breadfruit, conducting horticultural and ethnobotanical studies on this important Pacific staple crop for 30 years. Her extensive fieldwork on over 50 islands in Micronesia, Polynesia, and Melanesia enabled the NTBG to establish the world's largest collection of breadfruit at its Kahanu Garden in Hāna, Maui. The Breadfruit Institute was created to promote the conservation and use of breadfruit for food and reforestation.
Current research involves collaborative projects to develop in vitro methods to conserve and distribute breadfruit cultivars; nutritional and salinity studies; molecular and morphological studies to understand taxonomic relationships, origin, and distribution of breadfruit in the Pacific; and ethnobotanical studies on traditional uses of breadfruit in Polynesia and Micronesia.
Dr. Ragone is an Adjunct Professor at the University of Hawai`i in the Department of Tropical Plant and Soil Sciences. She is the author of more than 80 publications on breadfruit, ethnobotany, horticulture, and native plant conservation. Dr. Ragone holds a Ph.D. and M.Sc. in Horticulture from the University of Hawai`i and a B.Sc. from Virginia Tech.

Michael (Mike) DeMotta has served as Assistant Director of Living Collections and Horticulture for the NTBG organization since the latter part of 2006. He previously served as Horticulturist and then Manager of Living Collections at NTBG’s Limahuli Garden and Preserve.
Mr. DeMotta was born and raised in Honolulu and attended the University of Hawai`i. His interest in horticulture was inherited from his family, and he began growing orchids and ferns at the age of 12. His exposure in school to Hawaiian studies and the art of hula led to a keen interest in native Hawaiian plants, which he began growing in earnest in 1997. During this time he developed many of his own techniques to germinate plants from seeds and cuttings which were otherwise difficult to grow.
He oversees the living collections and horticultural practices of the organization’s gardens, with a particular focus on the collections at NTBG’s southshore gardens and adjacent Headquarters.

Scott Sloan oversees the care and maintenance of infrastructure, and building projects, at NTBG's properties on the south shore of Kaua`i, including its headquarters campus and research facilities, McBryde Garden, and Allerton Garden, as well as properties outside the gardens proper, such as the Southshore Visitors Center Garden.
While pursuing his horticultural degree in the University of California system in the late 1980s, he graduated from NTBG’s Horticultural Internship Program. This experience led to the institution forming a special internship at its Kahanu Garden in 1989 and requesting that Mr. Sloan stay on in that capacity. Subsequently, he held various horticultural positions in the McBryde Garden, with increased levels of responsibility, and headed both the gardening and physical facilities departments for 12 years.
In addition to caring for the existing physical facilities (including buildings, irrigation, roads, stream crossings, and paths), projects include seeking an alternative water supply by restoring a tunnel system that once existed in the plantation era. He is also working on the expansion of housing facilities for students and visiting scientists.
His professional affiliations include the Landscape Industry Council of Hawai‘i and the Steering Committee of the Kaua‘i Landscape Industry Council.

Kāwika Winter joined the NTBG in 2005 as the Director of Limahuli Garden and Preserve. Born and raised in the ahupua‘a of Wai‘alae, Kona, O‘ahu, Kāwika grew up in the islands with the mountains and the ocean as his playground. He went to the University of Hawai‘i at Mānoa (UHM) where he received a B.A. and an M.S. in botany. He is currently working on the completion of his Ph.D. from UHM which focuses on the reciprocal influences that cultures and plants have on each other’s evolutionary trajectories.
