National Research Highlights
In New York City, the Value of Urban Trees Adds Up
Year: 2019
New York City’s urban forest produces cleaner air, lower energy costs, reduced ultraviolet radiation, and less storm water in the city’s sewer system. USDA Forest Service scientists and partners analyzed a sample of the city’s 7 million trees and found that they provide services with an annual value of more than $100 million.
Forest Inventory and Analysis Urban Monitoring Expands to Include 26 Cities
Year: 2017
In collaboration with state and local partners, the Forest Service’s Forest Inventory and Analysis (FIS) Program has expanded urban forest monitoring to include 26 cities. FIA recently crossed a major milestone with data collection underway in more than 25 percent of the program’s proposed cities, making urban inventories active in all four national FIA units.
Forest Inventory and Analysis is Coming to a City Near You
Year: 2016
In collaboration with state and local partners, the U.S. Forest Service’s Forest Inventory and Analysis Program (FIA) has begun monitoring the urban forest resource with special focus on the nation’s largest cities. FIA recently completed its first urban inventory report that describes the urban forests of Austin, Texas.
