Trees – the True Urban Warriors – Dr Nina Bassuk, Cornell University
Trees benefit cities in many often-overlooked ways. They not only beautify concrete backdrops, but also improve the quality of our urban lives by providing shade, reducing storm runoff, filtering air and providing homes for birds and insects. Trees face big challenges, however, growing up in cities, largely because of drought and poor soils. To help trees survive these concrete deserts, Dr Nina Bassuk and her colleagues at Cornell University have been evaluating trees and shrubs for their ability to adapt, including developing resilient hybrid oak trees. A parallel research track aims at remediating urban soil conditions to reduce urban tree stress.
