Passive Irrigation of Landscape and Trees for growth and Urban Cooling
With drier conditions expected in the future we need to make better use of any rainfall by directing it towards landscape and trees to hold water in the environment and help with tree growth. Passive irrigation needs to be designed into landscape and involves thought around water flows drainage and systems to treat water and make it available for plant use. Examples of different approaches from around the world will be discussed and systems in Australia that are achieving amazing results in tree growth and cooling outcomes will be detailed. Having water held in the landscape can create cooler micro climates by allowing plants access to water in warmer conditions. Systems can be as simple as tilting a path slightly towards a tree swale to allow rainfall to be directed towards trees. It is important to ensure drainage is included into the design to ensure we don't drown trees and plants. Tree growth in systems in Broadmeadows are growing three times faster than trees simply planted in a park. Different approaches will be outlined and discussed in detail.
