What nickname is given to frailejones due to their massive hydrological role in the mountains?

Answer

Water factories

Frailejones, members of the genus *Espeletia*, are critically important to the Andean ecosystem because they continuously capture mist and humidity. This absorbed moisture is slowly released into the soil and regulated into rivers and streams, providing a stable water supply. This essential function of stabilizing regional water flow leads to them being widely described as the 'water factories' of the mountains, a system-wide ecological service benefiting down-valley cities and agriculture.
