Using botanic gardens and arboreta to help identify urban trees for the future
Diversification of urban forests is essential to enhance their resilience to future biotic
threats as well as those posed by a changing climate. Arboreta and botanic gardens
host a wide range of plant material that can be evaluated to inform tree selection
policy. This study demonstrates that plant functional traits, such as the water potential
at leaf turgor loss, can be highly instructive when developing evidence-based
recommendations for urban environments.
