Many species of birds, bees, and other pollinators face a precarious future in our urbanizing landscapes. Biodiversity is threatened at local to regional scales by habitat degradation. But there is some hopeful news: homeowners, individuals,...

Trees grow with, and adjust to, large lateral and vertical loads caused by wind and gravity. Storms with strong winds and ice can push trees beyond their ability to reconfigure or fall back to reduce drag. Exceeding tree structural ice and wind load...

Historic urban grasslands include greenspaces of historic value designed for passive and active recreation in the human built environment. Urban grasslands such as cemeteries and parks present unique challenges to landscapes designed in the early...

The effects of urban development write a profound signature on the landscape. Soils are inevitably compacted and regraded or paved over. We have developed techniques that can remediate these degraded soils and provide a long-term solution towards...

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...

Understanding carbon footprint (CF) terminology and the science underlying its determination is important to minimizing the negative impacts of new product development and assessing positive or negative cradle-to-grave lifecycle impacts. Life cycle...

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...

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?...

A certification program that provides guidelines for "sustainable land design, construction and maintenance practices." SITES can be applied to areas with or without buildings. The website details the areas of focus of the initiative, including...
