Grass Biomass in experimental plots, Hakalau Forest, Hawaii, 2015
Description
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. Specifically, this data set provides grass biomass data for plots where we implemented a grass removal/seed addition experiment in order to look at how these two factors relate to each other in limiting native plant recruitment. As a part of this we wanted to understand the underlying variability in grass biomass under different canopy trees and across habitat types.
