Stemflow refers to a part of precipitation that is intercepted by leaves, twigs, and branches and eventually channeled into soil through trunk or stem, which further could be transported and redistributed into deeper soil layers through preferential pathways such as roots. Numerous field observations indicate that stemflow, as a highly localized point input of rainwater and solutes around tree/shrub bases, plays a wide array of roles in ecosystem functioning, likely generating hot spots and moments of water and nutrients fluxes.
