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, assumin!
 g 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
>1), general setting (roadside, forest, etc.). Again, thank you for your
help.

Regards,

Matt Kasson
