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.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).

本数据集展示了在研究样地采集的6个物种的干叶凋落速率的5%分位数、均值±标准误（SE，n=7个样地，已剔除沿海样地）与95%分位数，同时包含水平降水（HP）沉积对叶片凋落物年度养分流失的潜在贡献百分比。鉴于并非所有物种均在各研究样地均有分布，研究人员对所有物种的叶片凋落物养分含量（即每平方米叶凋落物质量乘以凋落物养分浓度）进行了平均处理（详见附表S2），并将其与年度养分沉积量进行了对比。本研究同时给出了研究样地内跨物种平均的总叶片凋落物量，以及可通过水平降水（HP）抵消的年度凋落物养分损失占比。
