Research Activities
Forestry Research

Koa Silviculture
Silviculture of Regenerating Koa Forests. Granting Agencies: USDA, McIntire-Stennis and Tropical-Subtropical Agriculture Research Programs. Project period: Oct. 2003-Sep. 2008
Forest Health Assessment
Monitoring of Forest Health in Hawaii. Granting Agencies: US Forest Service, Forest Health Monitoring Program. Project period: Oct. 2003-Dec. 2009
Agroforestry Research
Restoration Agroforestry
Controlling Invasive Species with
Novel Agroforestry Systems Utilizing Native Plants. Granting Agency: USDA,
Tropical-Subtropical Agriculture Research Program. Project period: Oct.
2004-Sep. 2008. 
Restoration of Hawaii's forests requires tremendous expenditure of man-hours and plant materials. Governments and large conservation organizations may have the resources and dedication to accomplish this. Community groups, however, rarely have the ability to do more than pull weeds and attempt to stop the spread of invasive species. Our objective is to develop sustainable agroforestry systems using native plants.
Shade Coffee Analysis
Development of Shade Coffee Agroecosystems In Hawaii. Granting Agency: USDA, Tropical and Subtropical Agricultural Research. Project period: Oct 2003-Oct 2006
Agroforestry C
Sequestration
Agroforestry systems have a much greater inherent C
sequestration potential than agronomic systems without trees. Increased plant,
litter, and soil C can be sequestered in components with short to long turnover
times. This may be enhanced through the incorporation of N-fixing trees, since
soil organic matter has a highly conserved C:N ratio. Optimizing crop
productivity with C sequestration requires the appropriate selection of crop and
tree species and management practices.
