Plant seedling composition, abundance and substrate data

공공데이터포털

This data release includes data and metadata on seedling abundance, composition, and rooting substrate 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.

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.

Seedlings and cover data for Hakalau Forest, Hawaii, 2012-2016

공공데이터포털

This data release includes data and metadata on 1) avian diet 2) seed rain 3) understory plant composition 4) seedling abundance and 5) sampling locations for these sites. In addition it includes data on seedling abundance, grass cover and light levels for a grass removal/seed addition experiment . All sites were within Hakalau Forest National Wildlife Refuge on Hawaii Island. This study looked at multiple biotic interactions that potentially lead to self-reinforcing feedbacks within intact forest and degraded forest sites. This data in particular quantifies natural seedling regeneration in our sites, and the cover of different substrates and vegetation in the immediate area of these seedlings.

Hakalau Forest NWR seed rain, seedling, and plant data for 2017-2019

공공데이터포털

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.
