The Urban Forest Myth?
What do we really mean when we say the “urban forest”? Are we all in agreement? What does it need to thrive? How do we know? Is it similar to a natural forest? If not, how is it different? Are we making any mistakes in trying to create or maintain it? Are there studies and standards we need to apply to it? If we can’t answer these questions, we may not be helping support our urban forests.

Trees And The Design/Build Industries
Many industries work with and around trees, but there are many myths and misconceptions surrounding them. If tree professionals, landscape architects, engineers and architects better understand the needs of each other, as well as the needs of trees, truly sustainable designs are a more likely outcome.

Risks To Our Urban Forests And Woodlands
More people, organizations, municipalities and companies are realizing the importance of our tree canopy. But are we doing all we can to ensure a healthy, long-lived canopy? Are we helping or hurting trees in our urban forests and woodlands? There is data indicating that all might not be as well as we hoped. What are the risks to our urban tree canopy, and can we reduce them? This course looks at those risks, from grower to installer to the tree workers charged with caring for them. We still have a long way to go.

Midwest Invasive Plant Network

Rapid Detection And Intelligent Response: Combining AI And Human Intelligence To Detect Invasive Species
Rapid detection and rapid response has been critical to managing invasive species to ensure invasions are dealt with as quickly as possible, in order to minimize economic and environmental costs. Historically most detection was carried out by expert surveyors (e.g., botanists), but more recently, community scientists have also been providing valuable input in the process. At the same time, there has been a recent surge in the development of artificial intelligence (AI) tools to aid in the surveillance and processing of the data, including mapping to predict potential ranges. We need to ask some critical questions on how these tools work and how users, especially community scientists, can make the best use of them. The ideal RDRR strategy must be one of “rapid detection and intelligent response.”

Urban & Community Forestry Society

Sidewalks Vs. Trees: Integrating PROWAG, ADA And Urban Trees
As communities invest in safer and more accessible streets, urban foresters are increasingly challenged to preserve and expand tree canopy while meeting evolving accessibility requirements. The Public Right-of-Way Accessibility Guidelines (PROWAG), adopted by the U.S. Department of Transportation, went into effect in 2025 and establishes the national accessibility standards for sidewalks, curb ramps, street crossings, shared-use paths and other pedestrian facilities within the public right-of-way. These updated requirements come on top of already challenging infrastructure and tree conflicts that urban foresters navigate each day. As agencies implement PROWAG, the Americans with Disabilities Act (ADA) and critical sidewalk installation projects, urban forestry professionals have an important opportunity to shape projects that enhance accessibility while protecting the long-term health and benefits of the urban forest.
