Abstract

Urban trees provide numerous social, economic, and health
benefits, and growing and maintaining trees where people live,
play, and learn are crucial for sustainable and healthy communities
[1]. Cities worldwide have launched ambitious tree-planting initia-
tives to boost access to urban trees and reap the benefits that trees
provide [2,3]. Notable examples include the Million Trees Initia-
tive, the Great Green Wall for Cities Initiative, and the Tree City
USA program. More recently, through funding from the Inflation
Reduction Act of 2022, the US Department of Agriculture
announced an investment of over $1 billion in expanding access
to trees and greenspaces to combat extreme heat and other climate
crises [4]. This is the largest investment in urban forestry and
marks a new era of urban forestry in the USA.
