Look Out for Japanese Knotweed!
This summer and fall be on the look out for Japanese knotweed
(Polygonum cuspidatum) along Wisconsin waters. Japanese knotweed, also
known as Mexican bamboo, is an invasive perennial with hollow bamboo-
like red-brown stems. This species is often planted as an ornamental in
yards, but is of most concern when it is found along water bodies where
it can create a solid monoculture along the banks and spreads readily
downstream. For more information on the plant and for photos follow
these links:

If you find this species along water please report its location to the
Wisconsin Weed Watchers program. When you report the plant please have
location information that is as specific as possible:

The Weed Science Society of America has just started publishing the Invasive Plant Science and Management Journal. The first issue is for January-March 2008. I think there will be four issues per year.
This issue has articles on western juniper, common reed, perennial pepperweed, leafy spurge, invasive knotweed, Invasive species assessment protocol, sulfur cinquefoil to name a few.
The web site is http://www.wssa.net/WSSA/Pubs/index.htm .
The National Park Service's Heartland Inventory and Monitoring Network has
developed an invasive plant monitoring protocol. See "Protocol" section
heading at http://science.nature.nps.gov/im/units/htln/innp.cfm. Click on"PDF". The file is large (17.35 MB).
As with any protocol, the proposed methods have strengths and weaknesses.
In my opinion, the strengths of this protocol are its simplicity and speed
of implementation over relatively broad areas. The protocol has been field
tested in 11 parks. Two weaknesses, perhaps among many, are low ability to
detect change in plant abundance and lack of information on individual
plant occurrences.
Questions, comments, and suggestions are welcome - but may not be
immediately incorporated in the draft.

The first National Invasive Species Management Plan was published in 2001
and has recently been revised. The National Invasive Species Council staff
is now accepting public comments on this revised version of the plan.

BIOFUEL CROPS: PANACEA OR PANDORA'S BOX?
Weed Science Society of America
(LAWRENCE, Kan.) -- It's a Cinderella story. Weeds, scorned and trod on
for years and persistently excluded from the manicured gardens and
uniform crops of respectable horticultural and agricultural society are
fast becoming the darlings of a burgeoning biofuel industry. But not all
fairytales have a happy ending.
