Arboriculture and Urban Forestry Volume 39-Water Scarcity

The maintenance and expansion of urban forests is a major challenge in periods of low rainfall and restricted availability of appropriate-quality water sources for trees. The recent drought in eastern Australia has highlighted the need for innovation and new approaches to ensure tree health is preserved. Responses adopted by the Royal Botanic Gardens Melbourne and others have involved investigations into species more suited to changing climate conditions, assessment of tree and landscape water demand, understanding the hydrology of the site, effective irrigation delivery, management of the soil reservoir to optimize harvested stormwater, and provide soil water reserves for future high demand summer periods. This volume includes different papers that explore water scarcity and stormwater management and associated implications for urban forests.
