To all Forest Pathers: I am currently looking for Tree of heaven(Ailanthus altissima) seed from the following regions/states of the U.S. & Canada: Northeast- VT, NH, CT,RI, Quebec, New Brunswick, Nova Scotia Southeast- GA, AL, LA, MS, FL, TN, KY,AR Midwest- MN,SD,ND,MI,WI,NE,KS,MO,IA,IN,Manitoba, Saskatchewan West- WA,OR,WY,MT,NV,UT,CO, Alberta, BC Southwest-NM,TX,OK, Mexico We have already collected seed from all non-listed states. We are also aware that Ailanthus may not exist in some of the states listed. There is evidence that Ailanthus was introduced multiple times into this country on both coasts possibly suggesting that sub-populations of this species may exist if seed came from geographically different areas in China. We are currently working with a Verticillium fungus as a potential control of Ailanthus and want to test to see if all subspecies of Ailanthus are equally susceptible to our fungus, assuming that subspecies even exist. Please Email me if you have seed or could get seed (100-250 seeds if possible) from those regions listed above. Samples can be sent to the address below. Please dry before sending. Helpful information includes GPS coordinates or closest town name, number of trees seed was collected from (1 or help. Regards, Matt Kasson Matthew T.
