soft maples.
From 1843–2018, two large beautiful mature trees grew in 🇮🇪 Ireland, on the grounds of 🏛 Trinity College in Dublin,
[2]
just outside the building holding the Book of Kells. Said to have been planted there in a wet area of the grounds due to the tree's ability to draw from the soil and evaporate large quantities of water.

A process, I learned much later, called phytohydraulics, using evapotranspiration.
Terminology!
Unfortunately, after 175 years of faithful service, and suffering from heart rot, the trees blew down/were cut down.
