Stemflow infiltration areas into forest soils around American beech ( <scp> <i>Fagus grandifolia</i> </scp> Ehrh.) trees

The size of stemflow infiltration areas around the boles trees is currently a topic interest and debate within hydrologic community. There gap in our knowledge many wooded ecosystems need for more than few studies that have examined directly. Hence, this field study was specifically undertaken to mitigate existing data by providing direct measurements from high stemflow-producing American beech (Fagus grandifolia Ehrh.) trees. Different rates (290, 72 31 L h?1) were simulated using dye-infused four determined measuring areal extent dye on soil surface. Our results revealed ranged 0.0035 0.0951 m2 tree?1. mean basal area funnelling ratio 46.5 ± 1.8, whereas ratios per unit areas, , between 32.0 258.4. Despite intentionally rates, chosen compensate capacities forest soils, these reinforce fact an extremely localized input natural forests. Thus, results, even if specific F. particular type, support growing body work indicating are usually <1 m2, often much smaller, Moreover, values provide further evidence inputs important development hot spots near-trunk soils.
