Urban trees need rigorous criteria:Delegates told at Arboricultural Association conference

摘要

Trees should be selected for urban sites using more rigorous criteria to ensure that they survive and so deliver ecosystem services, Dr Henrik Sjoman told last week's Arboricultural Association Amenity Conference at Keele University in Staffordshire."Tree selection is key to the whole chain, and heat and drought are the biggest limitations on trees, so you have to look at how they handle these things," said Sjoman, who is lecturer and researcher at the Swedish University of Agricultural Sciences and curator at Gothenburg Botanic Garden. "Ecosystem services are related to tree size and health, and if we don't care about selection, we won't get the benefits."
