A pilot study to assess the structure, function, and health of Wisconsin’s street trees was initiated in 2002. Almost 900 plots were established in Wisconsin’s urban areas. Table 1 provides an overview of plot-level data, population estimates, and a calculated monetary value for Wisconsin’s street trees. Wisconsin has mid-sized street trees, dominated by Norway maple (30 percent), green ash (15 percent), honey locust (8 percent), and littleleaf linden (7 percent). Field assessments of crown dieb...

Emerald Ash Borer and Urban Trees Lab Notes
https://www.fpl.fs.fed.us/labnotes/?p=5480... [Invasive Species] [Urban Forestry] [Report] 2015
Madelon Wise
What’s the big deal about the emerald ash borer? According to the Colorado Tree Coalition, the emerald ash borer (EAB) has killed millions of ash trees since its discovery in 2002 and the number of dead ash is increasing rapidly. Ash species are abundant in planted and natural areas of urban forests, representing 10–40% of the canopy cover in many communities. Ash trees provide substantial economic and ecosystem benefits to taxpayers, ranging from increased property value, to storm water mitigat...

Locke, Dexter; Grove, J. Morgan; Lu, Jacqueline W.T.; Troy, Austin; O'Neil-Dunne, Jarlath P.M.; Beck, Brian
This paper presents a set of Geographic Information System (GIS) methods for identifying and prioritizing tree planting sites in urban environments. It uses an analytical approach created by a University of Vermont service-learning class called "GIS Analysis of New York City's Ecology" that was designed to provide research support to the MillionTreesNYC tree planting campaign. These methods prioritize tree planting sites based on need (whether or not trees can help address specific issues in the...
