Education:
B.S. 1970Biology, University of California at Riverside
Ph.D. 1990Botanical Sciences, University of Hawai`i at Manoa

Expertise / Specialty:

A major focus of his research has been mapping the distribution of plant communities throughout the Islands initially utilizing photo interpretation and, more recently, digital image analysis. He is currently a co-PI on the USGS Hawai`i Ridge-to-Reef project that has been studying watershed and sedimentation dynamics in two study areas on the islands of Kaua`i (Hanalei watershed) and Moloka`i (Kawela and Kamalo watersheds). This research includes components that address vegetation mapping and plant community dynamics, erosion and landside dynamics, water and sediment transport, sediment impacts on reef ecosystems, and modeling to integrate the various components. He has also recently worked with both the NPS Inventory and Monitoring Program and the Department of Defense (Army) developing protocols for monitoring plant species and communities.

Research Interests:

Hawaiian species and ecosystem conservation; alien species impacts; vegetation ecology; plant community mapping; GIS applications for conservation; plant species and community modeling; vegetation monitoring; assessment of forest bird populations; bringing science to conservation planning.

Background:

Jim Jacobi has been conducting research in Hawai`i for over forty years with primary emphasis on the ecology and status of native plant and bird species and communities, as well on the impacts of invasive species on Hawaiian plant communities.

Personal Interests:

The conservation of Hawaiian biodoversity
