Help us locate a "survivor" American elm tree


Researchers at the Northern Research Station, NRS-04, Delaware, Ohio would like to expand current efforts to screen American elm trees that may be tolerant or resistant to Dutch elm disease (DED). To facilitate this effort we are asking for the help of state foresters, park employees, and the interested public to identify large American elm trees on their landscapes.

Step 2: Provide Information About the Elm Tree

* DBH in inches:
Tree health:
DED symptoms:
Location characteristics:
* Land owner contact information for identified tree:
Are dead or dying American elm trees within one mile of identified tree?  
Are smaller healthy American elms within one mile of identified tree?  
* Person submitting this information:
Additional Notes:
*Required fields 

The identified elm trees will be compiled in a database and prioritized for sampling. When funding becomes available, we will contact land owners for permission to obtain cuttings for propagation and testing of the high-priority trees.
