The urban tree canopy is facing a worst-case scenario in the near future


Street trees are an aesthetically pleasing and beneficial feature of most modern cities. But a new study by Emma Hudgins, currently in the Department of Biology at Carleton University in Ottawa, estimated that 1.4 million trees in the U.S. alone will be killed by invasive insects by 2050, with considerable damage extending into cities in Canada as well. Her research was published in the Journal of Applied Ecology.
