As climate change progresses, trees in cities struggle

Associated Press  

SEATTLE — As the driest summer in Seattle’s record books ended, trees across the city were sounding silent alarms. “If trends hold, we are going to have a lot of trees die,” said Nicholas Johnson, an arborist for Seattle City Parks. “Once these trees are established, they grow incredibly fast,” said Rick Bailey, supervisor of the city’s forest management program. Climate change, however, is prompting many arborists to consider increasing them in their city’s arboreal palette — a practice called “assisted migration.” Arborists are looking for non-native species without “invasive tendencies,” said Scott Altenhoff of Oregon’s Urban and Community Forest Program. I’d rather plant one tree and maintain it really well than plant 10 trees and then not maintain it.” Costs of maintaining urban forests hit budgets in different ways.
