Tree restoration is a popular approach to mitigating climate change, but its hydrological impacts are often overlooked. Tree restoration increases evaporation, as well as increasing downwind precipitation due to enhanced moisture recycling. Our study shows that these combined effects can affect regions’ wetness or dryness, streamflow and water availability.
