The Department of Environmental Conservation will be purchasing tree seed this fall. If you are interested in selling seed to the Department, it will be necessary for you to call Janine Greene at the Allegany office at (716) 379-6369 to have your name entered on the collectors' list. You will also be asked the number of bushels you will be supplying. A confirmation letter will be sent to you verifying your participation in the program. This is a first-come, first-served situation so call as soon as possible. We cannot accept more seed than you estimate and are allotted, unless we do not meet our quota.
