Many species of birds, bees, and other pollinators face a precarious future in our urbanizing landscapes. Biodiversity is threatened at local to regional scales by habitat degradation. But there is some hopeful news: homeowners, individuals,...

Trees grow with, and adjust to, large lateral and vertical loads caused by wind and gravity. Storms with strong winds and ice can push trees beyond their ability to reconfigure or fall back to reduce drag. Exceeding tree structural ice and wind load...

Across the country, a number of cities are setting ambitious tree canopy goals to fight the trend of a decline in tree canopy. Among the many causes of canopy loss, development is a key driver, and is one that communities can significantly influence...

Phytoremediation is a green technology that utilizes specialized trees to remediate contaminated soils across the rural to urban continuum. The trees stabilize pollutants in the soil, trap the contaminants in their biomass, and/or break down the...

This seminar includes an invited presentation by Jon Hathaway, Associate Professor at the University of Tennessee Knoxville titled, “Tree Function in Stormwater Biofilters: The Green in Green Infrastructure” and a panel discussion with Mike Perniel (...

Urban stormwater is a major contributor to surface water degradation in the United States, prompting cities to invest in green infrastructure - methods that naturally capture, store, and slowly release runoff, such as urban trees. While rainfall...

Improving urban forests is one of the solutions to achieving several of the United Nations Sustainable Development Goals and making cities healthier and more livable for people. Priority should be given to protecting mature trees and promoting long‐...

While green stormwater infrastructure increases in popularity, we are still learning about the role of trees in these innovative practices. In this webinar, Andrew Tirpak will discuss recent research results from studies designed to characterize the...

The aim of this guide is to enable you to select appropriate trees for your planting scheme. By doing so, you will enhance the benefits bestowed on our communities by trees, help enrich our shared landscape and create a more sustainable urban forest...

As the pace of urban development increases, urban green spaces, and urban trees in particular, come in direct conflict with bulldozers and backhoes. With careful early planning and an understanding of how tree damage occurs, strategies for tree...

U.S. urban land increased from 2.6% (57.9 million acres) in 2000 to 3.0% (68.0 million acres) in 2010. States with the greatest amount of urban growth were in the South/Southeast (TX, FL, NC, GA and SC). Between 2010 and 2060, urban land is projected...

The Center for Watershed Protection reviewed a total of 159 publications to evaluate the research questions defined in the scope of this project:

1. What is the effectiveness of urban tree planting on reducing runoff, nutrient and sediment?...
