Landscape architects' responses to the usage of Hawaiian plants in landscaping

Abstract

The passage of the Endangered Species Acts 73 and 236 of the Hawaiʻi State Legislature (1992 and 1993) has required the use of Hawaiian plants in public landscape projects in Hawaiʻi. The research presented in this thesis investigated the tendencies which affect the use of Hawaiian plants by Landscape Architects in 2010, as well as an expected increase in use from 2010 to 2015. However, Landscape Architects indicated the same limitations of 1999: the availability is not meeting the demand and there is lack of knowledge in plant propagation, selection and maintenance. This study identified specialized nurseries as the key factor for the promotion of Hawaiian plants, and being the principal source of plants and information for Landscape Architects. Information gained through this study should be used to support relevant research, education, and extension actions for the promotion of Hawaiian plants in landscaping in Hawaiʻi at their full potential.
