New Elms for Minnesota?

2010 marks the fifth year that researchers at the Urban Forestry and Outreach and Research Nursery  have been collecting, cloning, and screening Minnesota-Miller Park - Comp.JPGnative elm trees for Dutch Elm Disease (DED) resistance. Mature trees that have survived – and thrived – in areas where DED is rampant are prime candidates for this screening work.

Researchers in Robert Blanchette’s Forest Pathology Lab at the University of Minnesota have been working side-by-side with our scientists to inoculate selections with the DED fungus.

Outstanding specimens like this American elm located in Eden Prairie, MN may offer new options for trees in our increasingly threatened urban forests.
