Abstract:Hawaii has seen widespread land use change and large scale land cover shifts. However, this
is only known either anecdotally or from a single locale studies. Therefore little information exists
on the rate or extent of land cover change across Hawaii. As such, this project produced statewide
annual maps from 1999 to 2016 of percent cover of forest, grass and bare earth, from LANDSAT
imagery, and attributed change to a spatial dataset of land management history. Statewide net
change resulted in a gain in woody cover primarily occurring in unmanaged areas and abandoned
agricultural land. These findings suggest that Hawaii is going through a forest transition, primarily
driven by agricultural abandonment and probable invasive species expansion, with additional
inputs from forestry production in areas with potential for native forest restoration. This work is
aids in a better understanding of the direct land cover consequences from land use changes in
