Due to climate change, water storage is becoming increasingly important. A wadi is a lowering in a street or park where excess rainwater can flow and infiltrate into the soil. So it is a place of temporary water.
Wadis are often combined with other public space functions, such as a playground or as a soccer field. They are also planted in roadsides of streets and along highways. Road salt and air pollution may therefore be a factor to consider when selecting species.

Trees in or near wadis must be able to withstand temporary wet feet. Wadis fill up when it rains heavily and are often empty again within 72 hours. Thus, there is no continuous wet soil. There may also be dry periods, when there is no precipitation for long periods of time.

Trees suitable for wadis are Taxodium distichum (Swamp Cypress) and Alnus glutinosa (Black Alder). Liriodendron tulipifera (Tulip Tree) and Lyquidambar styraciflua are also species that can tolerate temporary wet feet. Furthermore, Quercus palustris, Carpinus betulus or Alnus incana may be suitable.

Depending on the situation, several species may be appropriate. Therefore, contact us for advice and call 0411-621964.
