Tools To Assess Urban Tree Crowns

By Conni Kunzler | November 14, 2016

Asheville, NC (November 2, 2016) – U.S. Forest Service scientists from the Southern Research Station Utilization of Southern Forest Resources unit have developed software tools that managers and others can use to easily assess the extent of urban tree and forest stand crowns and monitor the health of trees in urban and nonurban settings.

11-03-urbancrowns_middleUrbanCrowns is a software tool designed to assist urban foresters, arborists, and community volunteers with assessing and monitoring urban tree crowns.

The program analyzes a single, side-view digital photograph of a tree and computes the following crown metrics: height, diameter, ratio, volume, density, and transparency.

Potential uses of the UrbanCrowns program include monitoring individual tree growth over time, detecting disease or insect damage in early stages, and providing data to quantify tree benefits such as carbon sequestration, rainfall interception, energy conservation, pollution removal, and oxygen production. Read more about the tool and how to use it.

UrbanCrowns is a Windows®-based computer program used to assess the crown characteristics of urban trees. The software analyzes side-view digital photographs of trees to compute several crown metrics, including crown height, crown diameter, live crown ratio, crown volume, crown density, and crown transparency. Potential uses of the UrbanCrowns program include monitoring individual tree growth over time, detecting disease or insect damage in early stages, and providing data to quantify tree benefits such as carbon sequestration, rainfall interception, energy conservation, pollution removal, and oxygen production.
