Chad’s research and interests: My research and outreach is focused on exploring new species and alternative nursery production and planting practices to enhance establishment and long-term success of young trees in urban and community forests. I am also involved with the UMN Elm Selection Program which is focused on selecting, cloning, and screening Minnesota-native American, red, and rock elms as well as elms from worldwide sources for Dutch elm disease resistance and suitability for the landscape.

Ryan’s research and interests: I help to manage the MN Tree Inspector Program, a collaboration with the MN Department of Natural Resources. I also assist with research focusing on improving clonal propagation in elm as part of the U of M Elm Selection Program. A third aspect of my research is focusing on the utilization of urban grown ginkgo seeds for food and medicine. Our hope for the ginkgo project is to create a mechanism for harvesting and selling urban grown ginkgo seeds to alleviate concerns over the malodorous seeds, which often result in requests for these quality urban trees to be removed.

Ashley's research and interests: I support individual volunteers as they pursue education regarding trees and their care, as well as working closely with municipalities to set up community-based volunteer programs to educate the public and create a volunteer base to assist with tree care tasks. My research involves understanding indicators that determine environmental stewardship volunteer retention length through a series of surveys distributed to existing and new volunteers. Little research has been conducted on the understanding of retention length in environmental stewardship programs (e.g. Tree Care Advisor, Master Gardener, Master Naturalist).

Michael's research and interests: My interests are focused on utilizing GIS and remote sensing techniques to improve sustainability of urban green infrastructure, and transferring new technology to government agencies and landscape managers. Current research uses small unmanned aircraft systems (sUAS), or drones, to assess urban tree health and vigor using multispectral sensors for application of vegetation indexes such as NDVI. I also assist with public outreach and research in partnership with regional municipalities to improve urban forest management practices.

Research Fellow, Urban and Community Forestry

Urban Forestry Outreach, Research, and Extension Nursery & Lab

nort0105@umn.edu

Eric’s research and interests: My research focuses on how urban trees respond to the environmental conditions in urban forests. I use tree rings to help analyze urban tree growth through time and determine the impacts of construction activities, climate, and site characteristics on the performance of street and park trees. I work with volunteers in the Minnesota Tree Care Advocate program, the Minnesota Master Gardner program, and the Minnesota Master Naturalists program as well as the Minnesota Certified Tree Inspector program.
