Callery pear data collection training

Event information

Callery pear has become an aggressive invasive species in many parts of the midwest and eastern United States, outcompeting native trees and forming dense monocultures. Though this non-native species may have pretty flowers in the spring, they smell terrible.

Early detection is key to controlling new invasive species. You can help researchers, land managers and policymakers generate data on the distribution and density of this tree by taking our brief training on finding and reporting Callery pear in Minnesota.

We will collect data starting in April and ending in early October. 


Anyone in Minnesota is welcome to volunteer.




University of Minnesota Extension is committed to providing equal opportunity for participation in all programs, services, and activities. To request accommodations for persons with disabilities, contact Angela Gupta at agupta@umn.edu.

You can help monitor and prevent the spread of invasive species in Minnesota through our Terrestrial Invasive Species Participatory Science (TIPS) program. Family woodland owners, natural resource professionals, and community members can all become TIPS volunteers. Together we can advance invasive species research, management and policy on targeted participatory science projects.
