[MAIPC] [APWG] [External] Invasive plants and climate change

Thu Feb 14 12:41:54 PST 2019

All,
Here are a few invasive plant biocontrol researchers that I am aware of:

Bernd Blossey, Cornell
Richard Cassagrande and Lisa Tewsbury, University of Rhode Island
Roy Van Driesche, University of Massachusetts

Please note:  Roy Van Driesche is the co-author of a published biocontrol
review several years ago that listed the status of research at the time.
I've copied him in case he can point you in the right direction.

Best,
Cynthia Boettner
