April is Arbor Month and a new five-minute video produced by the Iowa DNR aims to help residents learn to properly plant trees and avoid very common mistakes—vital to the longevity of new plantings. Common errors such as planting roots too deep or too...

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...

Diverse perspectives and approaches to learning and knowing can strengthen our work in urban and community forestry. Indigenous and local knowledge is embedded in the concept of biocultural stewardship - an approach to working with communities...

Greg reviews the key components to maintaining our stressed landscapes with tried and true Sustainable Landscape Management practices.

Speaker: Greg Paige, Director of Horticulture and Arboretum Curator, Bartlett Tree Research Laboratories and...

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...

Field monitoring of urban trees is essential to learn how urban forests change over time. Many arborists and urban forest managers worldwide seek to understand how their tree systems are faring in terms of growth, health, and mortality. The Urban Tree...

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...

Tree planting can help communities achieve many resiliency goals such as cooling heat islands, reducing stormwater floods, and building neighborhood cohesion. But trees can only do these things if they survive and thrive to maturity. CommuniTree is a...

Ash tree species in North America are under mortal threat from the Emerald Ash Borer (EAB), now in 35 states and five Canadian provinces. There are ongoing efforts to conserve this native tree species by producing genetically diverse, resistant...

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...

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

An ever-growing, international body of research points to many human health and wellness benefits that result from nearby nature experiences. But what about trees? Two recent reviews have explored, first, the studies that focus on the urban forest and...

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...

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 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...

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...

This is an example of how a historic landscape and public garden used GIS to map, track, and monitor tree health on their grounds. The presentation highlights how one might be able to use GIS at their public garden and some of the key features GIS...

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...

Trees provide significant benefits to our homes and communities, but they may also become liabilities when they fall or break apart, causing property damage, personal injuries, and power outages. Learn how to inspect trees by identifying 7 of the most...

“Which plants should I grow, and how many?” The IMLS National Leadership Project, Safeguarding our Tree Collections, seeks to answer this fundamental question. Through structured comparisons of genetic data among major groups of seed plants, management...
