1. Weed survey halls of fame and shame
From: Barry Rice (bamrice(at)ucdavis.edu)
We are *really* encouraging the stragglers to finish the weed survey.
I have posted on our web site the names of those fine folks who have
completed the surveys (thanks), at
http://tncinvasives.ucdavis.edu/survey.html
Count the stars next to your name!
In the same vein, I have also posted the preserves lacking survey
coverage. See if you think your state has been adequately covered.

2. Purple Loosestrife videos
From: Kyle Stockwell (kstockwell(at)tnc.org)
Here is some information about videos on biocontrol of Purple
Loosestrife, from Cornell.
"Rearing of Biological Control Agents for Purple Loosestrife," 1998, 24
minutes.
Shows natural resource managers, entomologists, horticulturists and
educators how to rear host-specific enemies to control this plant. These
natural enemies have the ability to reduce the abundance of purple
loosestrife to less than 5 percent of the
pre-release levels."
"Restoring the Balance: Biological Control of Purple Loosestrife," 1997,
28 minutes.
Reviews the invasion and spread of purple loosestrife, describes
management alternatives, gives reasons for biological control and shows
the importance of restoring diverse plant communities in North American
wetlands."
Both videos are available from the Cornell University Media and
Technology Services AV Center, 7 BTP, Ithaca, NY 14850 for $24.95 each,
or $36 for both titles if they are ordered together."

3. Euphorbia cyparissias
From: Bruce Hammond (bhammond(at)tnc.org)
TNC's Massachusetts Islands Program is confronting an infestation of
cypress spurge (Euphorbia cyparissias) at our Katama Plains preserve.
This species is closely related to leafy spurge (E. esula), which I
understand often invades midwest prairies. Can anyone suggest effective
control strategies for E. cyparissias?
Thank you!
