Model estimates of water balance components for a young secondary forest (YS, 60 years-old) and an old-growth North Patagonian forest (OG, >500 years-old) located in northern Chiloé Island, Chile, under current climate.

Model results are the average of 100 simulations per stand (see Methods for details), with annual sum of rainfall averaging 1970–2000 mm year−1. Literature refers to values reported by independent studies in Chilean temperate rainforests and comparable forests elsewhere. sd: standard deviation; %: percentage of total annual rainfall; ET: Evapotranspiration (sum of canopy interception and transpiration). sd: standard deviation.
*(1) Data for other broad-leaved evergreen forests, ca. 200 years old. Annual rainfall 2500 mm year−1[82], [83]. (2): Mixed deciduous-broad-leaved old-growth forest. Annual rainfall 2400 mm year−1[12]. (3) Mixed broad-leaved and conifer forest, ca. 200 years old in New Zealand. Annual rainfall 3400 mm year−1[84]. (4) Annual rainfall 1700–4500 mm year−1, data from evergreen, broad-leaved forests with 90% cover [85]. (5) Annual rainfall of 2427–3991 mm year−1[86], weather stations of Castro and Punta Corona.
