1. Monitoring large areas (Saskatchewan)
From: Ann Gerry (ann.gerry.erm(at)govmail.gov.sk.ca)

Saskatchewan is developing a province-wide exotic species monitoring
program. We are trying to figure out the best design for cost-effective,
repeatable sampling of very large areas. Permanent sample plots are not
feasible due to the variety of landowners and land uses. Repeated
measures analyses (comparisons over time) and the heterogeneous
distribution of exotics would necessitate huge sample sizes if strict
random sampling were adhered to. There has been discussion of sampling
along roads and other disturbed sites, but this doesn't address the extent
to which exotics are invading native vegetation.

Any thoughts or references to sampling protocols, reports, or articles
related to this topic would be profoundly appreciated.


2. Reed canarygrass conference/call for speakers (Washington)
From: Clay Antieau (clayton.antieau(at)ci.seattle.wa.us)

The Reed Canarygrass Working Group is sponsoring a Technical Session on
Exotic Species Management during the Society for Ecological Restoration
Northwest Chapter Conference in Bellevue, Washington, on April 6. The
session will feature papers on the management of reed canarygrass (and
perhaps another wetland/riparian weed species or two!).

We are inviting potential speakers to submit a brief abstract of a
proposed 15 minute presentation on this topic. We attempt informality, so
a paragraph or two along with your contact information is all we need.
Deadline for receipt of abstracts is March 12. Send this to my email
address, and we will confirm your presentation by March 16.

Contact me if you have any questions, or wish to be added to the Working
Group's contact list. Conference details (including registration) are
available at: http://www.halcyon.com/sernw/2001conf/2001conf.htm


3. Invasive species fact sheets online (Nationwide)
From: Jil Swearingen (Jil_Swearingen(at)nps.gov)

---Fired up because of a recent listserve, Jil Swearingen reminded us that
the Plant Conservation Alliance weeds web site has forty-four fact sheets
on different weeds. The most recent additions are:

English ivy (Hedera helix)
Porcelainberry (Ampelopsis brevipedunculata)
Cogon grass (Imperata cylindrica)
Tree of heaven (Ailanthus altissima)
Oriental bittersweet (Celastrus orbiculatus)
Exotic bush honeysuckles (Lonicera maackii, morrowii, tatarica, etc.)
Leafy spurge (Euphorbia esula)
Lesser celandine (Ranunculus ficaria)
Salt cedar (Tamarix ramosissima & others)
Giant cane (Arundo donax)

If you want to see these (or the other 34), point your web browser to:


4. My cost for Garlon 4 (Illinois)
From: Bill Klieman (nachusa(at)essex1.com)

I purchased Garlon 4 for $87 per gallon. The mineral oil, Penevator,
carrier was $9.20 a gallon from NOVCO in Columbus Ohio. Phone # is
614-486-8994. If you find a cheaper price let us know.


5. Microstegium Species Management Summary, and spot-burning tool review (Nationwide)
From: Barry Rice (bamrice(at)ucdavis.edu)

Faithful readers of the listserve know about the new Paspalum Species Management Summary. But it
will be news to all that we have uploaded a new element stewardship
abstract on Microstegium vimineum (Japanese stilt grass) which is stored
at: http://tncinvasives.ucdavis.edu/esadocs/micrvimi.html

Furthermore, we have a new "Tool Review" on line. This is for the Red
Dragon Vapor Torch. Interested in spot-burning? Read the review in our
Tool Shed, at: http://tncinvasives.ucdavis.edu/tools.html
