This data describes the coverage and composition of bryophytes and other ground cover 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.

This data release includes data and metadata on soil total (organic and inorganic) carbon, total nitrogen, organic matter, moisture and foliar carbon and nitrogen of dominant plants within Keamuku Maneuver Area (KMA) on Hawaii Island. Broadly, this study looked at how microtopography and biotic interactions influence post-disturbance recovery and native planting success in native shrub-dominated and non-native, invasive grass-dominated dryland habitats.
This data release includes data and metadata on 155 vegetation plots that were random stratified across different substrate ages and geological features at Keamuku Maneuver Area (KMA) on Hawaii Island in order to capture vegetation patterns across the landscape in relation to geology and climate. This data set also includes coordinates for the plots and geological data. This data was also used to determine dominant vegetation types across KMA.
This data release includes data and metadata on post-disturbance native shrub recruitment and survival within recovering vegetation after disturbance for sites within Keamuku Maneuver Area on Hawaii Island. This study looked at how microtopography and biotic interactions influence post-disturbance recovery in native shrub-dominated and non-native, invasive grass-dominated dryland habitats.
This data includes plot location, elevation, canopy density, canopy species, and char height for each plot that was surveyed for this study. All plots were located in the burn scar of the 2018 Keauhou Fire in Hawaiʻi Volcanoes National Park, in the area known as the "Mauna Loa strip", located on the south flank of Mauna Loa.
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.

This data release includes data and metadata on seedling counts for native woody species, for plots that were established to monitor the efficacy of post-fire seed addition in Hawaii Volcanoes National Park on the Island of Hawaiʻi. All plots were located in the burn scar of the 2018 Keauhou Fire in Hawaiʻi Volcanoes National Park, in the area known as the "Mauna Loa strip", located on the south flank of Mauna Loa.
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.
This data release includes data and metadata on soil carbon (C) and nitrogen (N) in sites where litter was experimentally manipulated. 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.

This data release includes data and metadata on plant functional group and substrate cover, as well as location information, and soil depth data, for plots that were established to monitor the efficacy of post-fire seed addition in Hawaiʻi Volcanoes National Park on Hawaii Island. All plots were located in the burn scar of the 2018 Keauhou Fire in Hawaiʻi Volcanoes National Park, in the area known as the "Mauna Loa strip", located on the south flank of Mauna Loa.
This data release includes data and metadata on post-disturbance percent cover of recovering vegetation after disturbance for sites within Keamuku Maneuver Area on Hawaii Island. This study looked at how microtopography and biotic interactions influence post-disturbance recovery in native shrub-dominated and non-native, invasive grass-dominated dryland habitats.
This data release includes data and metadata for native outplant growth rates for an experiment that added large quantities of woody litter to a restoration forest in an attempt to lower soil nitrogen and exotic grass biomass. 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 and growth with large quantities of Metrosideros polymorpha litter in a forest dominated by Acacia koa.

This study aims to evaluate the effect of rat population control on the ability of Hibiscadelphus giffardianus to successfully establish seedlings. We compared H. giffardianus fruiting and recruitment in a stand treated for rats and a neighboring control stand. The study was conducted in two neighboring kīpuka, Kīpuka Puaulu and Kīpuka Kī, which are patches of well-developed forest surrounded by more recent lava flows. These kīpuka lie 2.5 km northwest of Kīlauea Caldera in Hawai`i Volcanoes National Park on the island of Hawai`i. The 700 × 700 m rat-removal treatment area falls within Kīpuka Kī, and Kīpuka Puaulu served as a control. We monitored 181 mature, fruit-bearing individuals of this species, of which there...
