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‐...

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,...

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...

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...

This tree plan, not only comprises a history of trees that once stood in the Park and catalogues the trees currently standing, but also directs the succession and maintenance of the tree canopy that future generations of Park users will enjoy. As we...

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...

This paper is intended to help the stormwater engineering community more easily account for trees in runoff and pollutant load calculations so that they can more readily incorporate them into their stormwater management strategies.

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...

These 2 publications from Arboriculture and Urban Forests (Volume 43, Issue 1) share important information and reserach conducted on climate resilience of trees in urban areas:  

Street tree diversity is widely viewed as a key...

The maintenance and expansion of urban forests is a major challenge in periods of low rainfall and restricted availability of appropriate-quality water sources for trees. The recent drought in eastern Australia has highlighted the need for innovation...

Urban forests produce ecosystem services that can benefit city dwellers, but are especially vulnerable to climate change stressors such as heat, drought, extreme winds and pests. Tree selection is an important decision point for managers wanting to...

The first TGI report, published in 2015, identified eight critical gaps slowing the transfer of stress-adapted trees from upstream research to forest owners and managers. The gaps fell into three categories: Innovation, Policy, and Markets. TGI members...

Across the world, companies with a wide range of business models are making money from planting trees. These restoration enterprises are proving that restoring degraded forests and agricultural lands is not only good for the planet, but a good business...

Urban forests produce ecosystem services that can benefit city dwellers, but are especially vulnerable to climate change stressors such as heat, drought, extreme winds and pests. Tree selection is an important decision point for managers wanting to...

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?...
