Basal area in sampling plots, Hakalau Forest NWR

This data release includes data and metadata on tree and shrub identity and basal area within 5 m2 radius plots centered around old growth Acacia koa, planted Acacia koa, old growth Metrosideros polymorpha, and in open, exotic grass dominated sites. Our goal was to ask if understory communities differed between these habitat types and how this relates to other ecosystem factors such as seed rain and exotic grass cover. Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration.
