Hakalau estimated frass production during a koa moth outbreak, 2013 This data release includes metadata and tabular data that document estimates of litterfall, koa moth (Scotorythra paludicola) caterpillar frass production, soil nutrients, and foliar nutrients during 2013-2014 at Hakalau Forest National Wildlife Refuge. During this time, there was a massive defoliation event of Acacia koa (koa) trees by the koa moth. We monitored these metrics in 4 sites that varied in forest structure and composition at Hakalau. We used litter traps to monitor koa litter fall over time and foliar %N to estimate N inputs from litter. We used caterpillar counts, koa canopy estimates, frass production rates, and frass %N to estimate N inputs from frass on the landscape. We used resin bags under koa...

During this time, there was a massive defoliation event of Acacia koa (koa) trees by the koa moth. We monitored these metrics in 4 sites that varied in forest structure and composition at Hakalau. We used resin bags under koa canopy where frass was directly falling as compared to open grass sites where no frass was falling to monitor soil inorganic nitrogen and phosphorus over time. By comparing soil with frass inputs to frass inputs over time we could watch for...

Broadly, this study asks how seedlings densities relate to their microsites in terms of grass cover and nurse log and moss presence.

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 addresses bird-mediated seed rain as measured by aerial seed rain traps under koa and ʻōhiʻa trees along two transects moving from intact forest uphill into restoration...

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.
