This data release includes data and metadata on tree and shrub basal area as well as bird-mediated and passive seed rain for sites selected to have a range of understory cover under canopy trees (Metrosideros polymorpha and Acacia koa). It also includes seedling germination and survival data for a large-scale seed addition and grass removal experiment that varied both seed rain and grass cover. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration.

This data release includes data and metadata on a large-scale seed addition and grass removal experiment that varied both seed rain and grass cover. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration. Specifically this data decribes the percent cover of grass over time in plots where we experimantally added varying levels of seed rain and/or manipulated grass biomass manually.

This data release includes data and metadata on bird-mediated and passive seed rain for sites selected to have a range of understory cover under canopy trees (Metrosideros polymorpha and Acacia koa). All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration. Quantifying natural seed rain rates in different habitat types was needed to better understand how these thresholds function.

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.

This data release includes data and metadata on seedling germination and survival for a large-scale seed addition and grass removal experiment that varied both seed rain and grass cover. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. Broadly, this study asks what thresholds of seed rain and native and exotic plant cover are needed for passive forest regeneration. As a part of that, we created an experiment that varied seed rain in order to ascertain if seedling recruitment exhibits threshold effects.
