Ice or snow loads can cause branch breakage or failure of entire trees and shrubs. Branches or entire trees that fall in storms can impact homes, vehicles, power lines and block roads. After a storm, the first priorities are safety and restoration of...

Urban forests are recognized for the multiple benefits they provide to city‐dwellers.
However, climate change will affect tree species survival and persistence in urban
ecosystems. Tree failures will cause economic losses and jeopardize...

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...

Employers are desperate to fill a labor shortage on the front lines in urban forestry, yet struggle to source and retain a sustainable workforce. Few employers have successfully tapped into the supply of workers in communities with the lowest tree...

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...

Oaks are critical to the health and function of forest and shrubland habitats in the United States, but many native oaks are threatened with extinction in the wild. Ongoing conservation efforts exist for some species, but with growing threats and...

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‐...

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...

This publication provides forest resource statistics contributing to the 2020 Resources Planning Act (RPA) Assessment to provide current information on the Nation’s forests. Resource tables present estimates of forest area, volume, mortality, growth,...

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...

Although the effects of climate on species richness are known, regional processes
may lead to different species richness–climate relationships across continents
resulting in species richness anomalies, especially for tropical groups....

Insect and disease infestations pose major threats to several North American forest tree species.
Scientists and managers from throughout the United States Forest Service developed a conservation priority-setting framework for forest tree...

North American forests and forest management institutions are experiencing a wide range of significant ecological disturbances and socioeconomic changes, which point to the need for enhanced resilience. A critical capacity for resilience in...

Urban trees serve a critical conservation function by supporting arthropod and vertebrate communities but are often subject to arthropod pest infestations. Native trees are thought to support richer arthropod communities than exotic trees but may also...

Drought is a recurrent stress to forests, causing periodic forest mortality with enormous economic and environmental costs. Wood is the water‐conducting tissue of tree stems, and trees modify wood development to create anatomical features and hydraulic...

The evidence is mounting around the compounding benefits of the urban forest. We know trees in cities clean air and water, reduce energy demands, and improve the people's overall quality of life. Yet, tree failure may have serious negative consequences...

This brochure is a self-guided tour visiting trees of special interest on the Storrs campus of the University of Connecticut. The University of Connecticut Campus Arboretum serves as both an
aesthetic and scholarly resource for the University...

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...

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...
