Cost Benefit Analysis of Planting Stock – a Three-Year Study

Researcher: Monica Randazzo

The Cost Benefit Study of Planting Stock aims to address a small component to this larger question by asking another: are there significant differences in growth rates and survival during the establishment period (3 years) among trees of different stock types? Read More...

NDVI Tree Canopy ImageUsing Drones to Monitor the Health of Individual Newly Planted Trees

Researcher: Michael Bahe

Survival of newly planted trees is critical to a sustainable forest in urban areas. Trees planted in these areas are typically purchased from commercial nurseries and delivered for planting in a variety of forms. With the help of low altitude drone imaging, a quantifiable, genus specific, healthy baseline is being established using the Normalized Difference Vegetation Index (NDVI) calculated using low altitude aerial imagery.

Indicators of Environmental Stewardship Volunteer Retention

Researcher: Ashley Reichard

The primary objective of this research project is to collect data on the larger cadre of environmental stewardship volunteers (in this case, Citizen Pruners, First Detectors, Master Gardeners, Master Naturalists, Tree Care Advisors, and Tree Stewards) to determine if there are specific indicators for volunteers who will stay involved longer than others. Read More...

NDVI Tree Canopy ImageSustainable Harvest Mechanisms for Ginkgo biloba Seeds for Medicine and Food

Researcher: Ryan Murphy

Ginkgo biloba is considered to be one of the best climatically adaptive species for the North Central Region. The species is highly resistant to disease, stress, and pests. The University of Minnesota will develop sustainable mechanisms to harvest ginkgo seeds for medicine and food, thereby, preventing the removal of mature female ginkgo trees that produce malodorous seeds in the urban environment.

Elm Project

Researcher: Chad Giblin

Many urban areas in the mid-20th century had closed canopy streets lined with American elms. By the end of the century, a large percentage of those areas had complete canopy loss due to the Dutch elm disease fungus. The elm project at the University of Minnesota aims to reestablish the tree that had garnered the admiration of past generations through selective breeding of trees that are tolerant or resistant to the pathogen.
