The overall amount of leaf litterfall at the study site averaged across species and the estimated proportion of annual litterfall nutrient loss that could be offset by horizontal precipitation (HP).

Shown are the 5% percentiles, mean ± SE (n = 7 sites, i.e. excluding coastal site) and 95% percentiles of dry leaf litterfall rates and potential percentage contribution of HP deposition to annual nutrients lost in leaf litter across the six species sampled at the study site. Since not all species were present at each site, leaf litter nutrient content (i.e. leaf litter mass per m2 multiplied by litter nutrient concentration) was averaged across all species (S2 Table) and compared to the annual deposition of nutrients.
