The legacy of institutional racism including redlining and other discriminatory policies have paved the way for an urban landscape that is deeply divided. Too often, a map of tree canopy is also a map of income and race, with corresponding public...

To keep pace with the increasing impacts of climate change, people across the country are planting more and more trees. But how will you track these trees to make sure you get the optimal return on this investment of time and resources? Join us for a...

With increased intensification in cities throughout the world, urban trees are often at risk of becoming damaged by construction impacts, such as utility trenching or pavement / sidewalk repair. If the damage is severe and a tree loses a lot of its...

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...

The restoration of trees remains among the most effective strategies for climate change
mitigation.We mapped the global potential tree coverage to show that 4.4 billion hectares
of canopy cover could exist under the current climate....

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 (...

The Earth's climate is changing. Impacts - including higher temperatures, rising sea levels, and longer periods of extreme weather - are...

A community with dense overhead tree canopy may benefit from reduced stormwater runoff volume through interception, transpiration, and infiltration but may also suffer from excess nutrients leached to nearby receiving waters from leaf litter. Bill...

Iconic tree species include those native trees that once dominated the typical American city landscape. The American elm and chestnut are the first two that come to mind, and now ash trees are similarly under significant threat of loss. The USDA Forest...

An Urban Tree Canopy (UTC) assessment, which provides a measure of a community’s tree canopy cover, is important for understanding the extent of a community’s forest or tree resource. UTC assessments are often used for establishing and implementing...

The nation’s forest land area remains stable, but the composition and distribution of those forests is changing. The data supporting this assertion, along with other information on the status, condition, and trends in the nation’s forest resources, are...

Can urban trees and city winter weather protocols peacefully co-exist? Join us for a discussion of the latest research findings related to successfully growing trees under these conditions. Dr. Andrew Millward will walk us through his investigation of...

The American chestnut, whitebark pine, and several species of ash in the eastern United States are just a few of the North American tree species that have been functionally lost or are in jeopardy of being lost due to outbreaks of pathogens and insect...

NYC’s forested natural areas provide important benefits to the city including high-quality recreation, enhanced biodiversity, and improved air and water quality. The Natural Areas Conservancy (NAC) and the New York City Department of Parks and...

It is now almost three years since world leaders agreed to chart a course towards a better, more prosperous future for the planet and all its people. The 2030 Agenda for Sustainable Development, with its 17 Sustainable Development Goals (SDGs), has...

The role of urban forests continues to expand as society recognizes the potential contribution of green infrastructure to global sustainability, human health, and quality of life. At the same time, new knowledge and technology are expanding urban...

The webinar will provide Extension Agents with information and resources to promote pollinator habitats in urban and suburban forests. Pollinator habitats are important to all landscapes, including urban and suburban forests. Pollinators need numerous...

Inclement weather, particularly severe thunderstorms and wintry precipitation, is a major cause of damage to urban forests. In this webinar, we will learn how inclement weather impacts trees and how we can create storm-resilient urban forests through...

Learn about how to evaluate sites that are ideal for urban tree health and growth and resources and tools on how to better assess these sites.
