Time: 9:00 a.m. to 5:00 p.m.

Activity: Conduct field inoculations of young hybrid chestnut trees this July. No experience necessary. (Sign up for an hour or the whole day).

Roughly 1,500 seedlings at the Raystown Lake hybrid chestnut orchard will be inoculated with the SG2,3 strain of Cryphonectria parasitica. On July 16th volunteers will work together with staff to inoculate seedlings with the chestnut blight fungus. After 6 months, cankers will be rated to quantify resistance. The best trees will be retained for additional screening in 2 years.
