Bryophyte Sampling Location

공공데이터포털

This data release includes sampling locations for the coverage and composition of bryophytes, other ground cover and seedling abundance. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. This study aims to evaluate the role of bryophytes in seedling recruitment and thus forest regeneration in different forest types. We compared bryophyte composition and coverage between tree species (Acacia koa and Metrosideros polymorpha) and forest types (intact forest and restoration forest) and then sampled native woody seedling recruitment in the bryophytes as well as other ground covers, such as leaf litter, bare soil, and exotic grass.

Basal area in sampling plots, Hakalau Forest NWR

공공데이터포털

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.

Hakalau Forest NWR seedling and substrate data, 2015

공공데이터포털

This data release includes data and metadata on seedling counts and substrate cover in forest plots in Hakalau Forest National Wildlife Refuge on Hawaiʻi Island. Broadly, this study asks how seedlings densities relate to their microsites in terms of grass cover and nurse log and moss presence.

Hakalau Forest NWR litterfall biomass and nutrient data

공공데이터포털

This data release includes data and metadata on litterfall rates of the two dominant canopy trees (Metrosideros polymorpha and Acacia koa) in a restoration forest in Hawaii. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. Broadly, this study looked at the ability to alter soil nitrogen cycling, exotic grass biomass and native outplant survival with large quantities of Metrosideros polymorpha litter in a forest dominated by Acacia koa.
