    Transpiration, Evaporation and Interception

    In this Monday episode of Talking Trees, we explore three essential water-related processes—transpiration, evaporation, and interception—that shape how trees interact with their environment and regulate the water cycle. We discuss: Transpiration, the movement of water from roots through the plant and its release as vapor from leaf surfaces, driven by sunlight, humidity, and stomatal activity Evaporation, the transformation of water from liquid to vapor at exposed surfaces such as soil, bark, or leaf litter, contributing to cooling and moisture redistribution Interception, where rainwater is temporarily held by leaves, branches, and bark, delaying or reducing the amount reaching the ground and influencing infiltration and runoff How these processes vary with canopy structure, species, and climate, playing a key role in microclimate regulation and urban hydrology Their combined impact on tree health, drought resilience, and stormwater management Understanding these dynamics helps arborists and planners appreciate how trees actively shape local environments and water systems.
