The Flora of Hawaiʻi is globally recognized as being unique. As a result, it has been the focus of much research that informs our conservation practices today. Hawaiʻi has also long been at the forefront of confronting the extinction crisis. Lessons learned here are quickly picked up in other regions where invasive species threaten vulnerable native ecosystems. Because of the high number of threatened plant taxa, many government agencies and institutions have also produced technical reports for their projects that can inform restoration strategies for congeners or closely related taxa.

Plant conservation research is broad, covering several disciplines. For our purposes, we have identified the following topics:

Climate Change: Assisted Colonization (mitigating threat), Climate Change: Vulnerability Assessment (identifying threat), Inter/Intra-Population Variation (molecular study), Mutualisms (identifying pollinator, disperser), Mutualisms (Mycorrhizae), Phenology, Population Distribution (models), Population Size (surveys), Population Trends (monitoring of life stages & longevity), Propagation: Controlled Breeding, Propagation: Tissue Culture, Propagation: Vegetative Techniques, Reproductive Biology (mating systems: autogamy, outcrossing, apomixis), Restoration Methods: Outplanting Methods (seed sow, planting techniques), Restoration Methods: Strategy and Design, Restoration: Inbreeding/Outbreeding Depression and Heterosis, Seed Biology: Dormancy and Germination, Seed Biology: Soil Seed Bank, Seed Biology: Storage Conditions & Longevity, Taxonomy (phylogenetic relationships), Threat Control: Alien Invasive Plants, Threat Control: Insects, Threat Control: Mollusks, Threat Control: Small vertebrates, Threat Control: Ungulates

Laukahi maintains a database for publications on these topics to inform the conservation of native Hawaiian plants. This includes technical reports, dissertations, published papers, and other resources. It is searchable by taxon, author, and topics. For access to reports from this database or to include your research, please email us at:


Although much research has already been done, more is needed to inform conservation strategies. A recent survey of practitioners resulted in a list of priority topics available at the ʻResearch Prooritiesʻ link below. This resource is intended to promote directed research on the topics that will make the greatest conservation impact. It has been prioritized by practitioners who have access to the field sites and plant material needed to enable these studies. Please email us ( to add your research suggestions and priorities.
