All,

One useful example is the Gypsy Moth Slow the Spread (STS) project funded
by
USDA Forest Service and USDA APHIS PPQ.  It is implemented across 9 states
from North Carolina into Minnesota, the area includes North Carolina,
Virginia, West Virginia, Ohio, Kentucky, Indiana, Illinois, Wisconsin, and
Minnesota.   They have a national website housed at VPI which includes
discussions of dispersal rates with controls in place and without controls.
They are discovering that that rate of dispersal is regionally impacted,
some parts of the region respond more favorably than expected and some
parts
of the nation respond less favorably to the controls implemented.

I have attached a response I sent to another party about this so you can
correspond with any of them to see if it turns out to be a useful lead.

Hi folks, We are currently working on an Invasive Plants Environmental
Impact Statement for Region 6 of the Forest Service.  My question is:

      Does anyone have any solid information (preferably quantitative) on
reduction in rate of spread due to prevention practices?  The prevention
practices we're most interested in researching are washing of off road land
management activity vehicles before entering Forest Service lands, washing
of these same vehicles before leaving infested areas, use of certified
weed-free straw/mulch, reducing off highway vehicle access, managing
livestock movement patterns in grazing allotments.

For example, we'd like to project that the washing of vehicles before
entering FS lands will reduce the current rate of spread by _____%.  The
rate of spread for invasive plants most often found in the literature for
this part of the world is 8 - 12% annually.

Thanks.  Anything you may have; actual numbers, anecdotal stuff,
monitoring you've started; thoughts, hypotheses etc..... would be helpful.
