Dear forest pathology colleagues,
We would like to bring to your attention the website
http://www.iufrouruguay2011.org that provides information about the
upcoming IUFRO meeting, "Pathogens, insects and their associations affecting
forestry worldwide" which will be held in Colonia del Sacramento, Uruguay
8-11 November, 2011. The meeting will be a unique joint Forest
Entomology/Pathology meeting and I expect there will be many interesting
presentations and discussions. Given the location of the meeting in
Uruguay, we anticipate participation from across Latin America but the
meeting will focus on topics of international scope and we are thus
encouraging scientists from all countries to participate.
The meeting location of Colonia del Sacramento is a quaint town located on a
small penninsula in el Río de la Plata, and can be reached by a short ferry
ride from Buenos Aires on the other side of the river in Argentina. Colonia
is the oldest town in Uruguay, originally settled in 1680 and many of the
original stone and stucco buildings are still standing and used for
every-day life.
I'm really excited about this meeting as it will be unique in many ways. If
you think you might be interested in participating, please fill out the
information card at http://www.iufrouruguay2011.org/contact
Any specific questions about the meeting should be directed to our host, Dr.
Guillermo Perez at guillermoiufro2011(a)gmail.com.

Greetings All
We will be filling an entomologist position in the near future and as part
of the process would like to hear from those interested in working in the
Southwestern Region, Flagstaff, AZ. Responses will help determine how
this will be advertised and grade of consideration for the position. The
outreach is also posted on the Lotus Notes outreach database. Please
help me in distributing this widely and to anyone that might have an
interest. If you have questions don't hesitate to contact me.

Hi everyone,
Jim Slavicek and I are working together on the restoration of American elm
(Ulmus americana). American elm was a dominant species in many swamp and
floodplain forests in eastern US and Canada before Dutch elm disease (DED)
reduced its populations. At our lab, we have a small plantation of elms in
various stages of testing for DED tolerance. Several genotypes have been
shown to tolerate DED, and a large portion of the progeny from crosses
among these trees are DED-tolerant as well. We are currently testing the
potential of seedlings from DED-tolerant crosses to be used for restoration
plantings. It is our hope that large, stately American elm trees will
someday grace our floodplain and swamp forests once again.
We need more DED-tolerant genotypes of American elm to use as parent trees
for our plantation in order to have enough genetic diversity to use it as a
seed orchard for large-scale plantings. We are looking for healthy American
elm trees larger than 24 inches DBH (diameter at breast height) that are
growing in areas that have had DED and that have not been treated with
fungicides to prevent DED. We are only interested in American elm trees
growing within its native range. If you see a survivor elm that fits this
description, please enter its location and DBH at our website:
http://nrs.fs.fed.us/disturbance/invasive_species/ded/survivor_elms/
We will compile these entries in a database, prioritize the elms for
sampling, contact land owners, and then collect small branches from the
trees to propagate and test them for DED-tolerance. Please forward to
anyone who knows how to identify elm trees and might have interest in this
project. Thank you for your help!
- Kathleen
