Benefits of passive infiltration, and tree growth and cooling quantified

1 June 2022

Research published on 30 March 2022 indicates that mature trees planted within the zone of influence of TREENET Inlets and leaky wells transpired, on average over the course of a year, 17% more water per unit of canopy area per day, and 21% more during the dry season. White cedar saplings with stormwater harvesting grew 65% higher and increased 60% more in diameter over a 3-year period when compared with saplings without stormwater harvesting. This is consistent with an observed 106% greater stomatal conductance and up to 169% greater photosynthesis rate in the dry season for saplings supported by harvested stormwater.

This study shows that stormwater harvesting and infiltration by TREENET Inlets provides significant benefit to white cedar trees growing in a suburban street.
