    dct:description "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." ;
