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 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.
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 contains the height of shrubs found along transects on the south facing slopes of Santa Cruz Island, CA. It was used in the analysis for the Manuspcript "Long-term impacts of exotic grazer removal on native shrub recovery, Santa Cruz Island, California". These sites were sampled in 2004 and 2016 to gain a longer term view on native shrub reestablishment into exotic grasslands after exotic grazer removal.
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.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
