The USDA Forest Service Native Plant Materials program funded the development of 403 American elm seedlings on the Chippewa National Forest, crossing Dutch elm disease-tolerant cultivars with native survivors. These seedlings, grown in greenhouses and moved to pots and latch houses, will be overwintered on the Blackduck District before planting in study plots in April 2011. This marks a milestone in the restoration project. Figures and data are provided for project completion in 2017, expenditures, and cooperating entities.

American Elm Restoration on the Chippewa National Forest Title text here 2010 Accomplishments The USDA Forest Service Native Plant Materials program paid for the development of 403 American elm seedlings that are crosses between Dutch elm disease tolerant American elm cultivars, and surviving American elm trees on the Chippewa National Forest. The pollination occurred in the spring of 2010, at the Northern Research Station in Delaware, Ohio. The seedlings were grown as tublings in a greenhouse, and later put into pots and moved to a latch house. At the end of the summer they averaged five feet in height. These trees will be moved to the Blackduck District tree cooler the first week of November, on the Chippewa National Forest. Here they will be over-wintered. They will then be planted in the three study plots in April, 2011. This will complete the production of seedlings for this research project. Figure 2.
