Question

How do trees affect hydrological cycle?

Answer 1

As there are usually substantial differences in evaporation between forests and other vegetation, changes in forest cover can have important impacts on the amount and timing of streamflow. ... The presence of forests, with deep roots, might exploit deep stores of water in the dry season and thereby reduce baseflows.

Answer 2

Forests are a critical cog in the global water cycle: Trees pull water from the ground and release it into the atmosphere as vapor through pores in their leaves in a process called transpiration, which can drive temperatures and rainfall across the globe.
