Pour points: A novel method for woodland water resource management

Vegetation plays a vital role in regulating the percentage of precipitation reaching the ground to nourish the root systems of plants both in the canopy and undergrowth, which consequently supports the survival of the entire forest ecosystem. Water arrives to the ground via multiple mechanisms, including throughfall (water falling directly through the canopy) or stemflow (water flowing down stems and trunks), while some is intercepted by the canopy leaves and does not reach ground level.
