Here, here, I concur. I have been pulling the leaves off ailanthus and
piling them at the base of the smaller trees. It doesn't kill them, but it
seems to stunt them. I was also curious if anyone had ever tried freezing a
sapling with CO2 or something similar. Sounds like it might be too costly,
but it may be 'eco-friendly', for lack of a better term.

Dear All,
Instead of any controversy about the use of commercial herbicides in
wildlands, why don't we all start to convert to the use of natural plant
herbicides, called allelochemicals?
If we start looking for the most effective ones now, we could have a group
of natural plant-based herbicides to use, some so strong that they remain
effective for up to two years, against annual grasses like cheatgrass, for
example.
Why should we wait for USDA or Monsanto to invent these new natural
herbicides for us?
I think a group of these email readers, who need a safe and effective
natural herbicide, with an annual grant from the Federal government, could
find some of these effective natural allelochemical herbicides for the
rest of us to use.
Sincerely, Craig Dremann (650) 325-7333

I hope Tasker will not tax us with generalities, thus tasking us with trying
to figure out what he specifically means.
I am dubious about acronyms, and the catchy labels from which they spring,
as they tend to become buzzwords that either lose their original meaning or
debase the terms of which they are composed. "Process flow charts" and other
impressive devices, when broken down into what they really say, don't amount
to much. The "integrated" aspects of IVM say little or nothing about
ecosystem function and lack specificity with respect to post-treatment
performance.
This is not to say that ecosystems should not be "managed," but herbicides
of any kind tend to be used under the rather simplistic logic, "Weeds bad,
kill weeds, keep killing weeds." That's simply not demonstrably good enough;
virtually all of the cases I have seen rely upon a time-limited set of
general observations (mostly impressive photos) or "surveys" that do not
reveal the long-term implications of ecosystem function. For example, if one
sprays herbicides on weeds, impressive results will follow and be
photographed. Such "data" don't prove anything with respect to ecosystem
function and "health." "Vegetation management" has too long been a euphemism
for killing plants indiscriminately. I would like to see the details of an
IVM program that truly integrates all relevant science.
To truly advance this important discussion, it will be necessary to
establish a tradition of being directly responsive to points made in a
sequence that moves quickly from generalization to theoretical foundations
to evidence, all with lines of relevance clearly evident and assessment,
action, and consequences feedback loops that fully describe the phenomena,
not sell them short. Specific examples which have been sufficiently
researched by independent entities and replicated by other disinterested
(out of the money loop) parties in accordance with the basic principles of
good science. Too much is at stake for the foxes to be in charge of the
henhouses--which should be transparent and open to all for inspection.

APWG:
Natural chemicals and compounds are chemicals and compounds, but in the
amounts and ways in which ecosystems and organisms deliver them they are
less likely to cause "whipsaw" injuries to ecosystems than industrial
chemicals "applied" in simplistic ways. But, presuming that "natural"
chemicals and compounds can be produced in commercial quantities, they, too,
can be "applied" in simplistic ways. Besides, we don't have such "natural"
chemicals available, and even if we did, there's no assurance that we would
know how to use them.
What we do have is the ability to be truly integrated in our approach to
ecosystem management and restoration, and we know (at least relatively
crudely but effectively) how to manage nutrients and organisms to move
toward dynamic stability. After all, that IS, at least the implied objective
of alien species control--isn't it?
Perhaps the biggest problem with alien species control it the presumption
that "good" species will somehow spontaneously occupy niches emptied by IVM
and other control measures rather than recognizing that there is most often
a need for quickly "managing" the weed-killed site with indigenous component
resistant to reinvasion. The proof of which approach was necessary or not is
in the ACTUAL results that hold up in perpetuity. Having to "re-spray" or
"re-treat" is curiously seen as part of so-called IVM, rather than a defect
in the underlying presumptions.

Dear Wayne and All,
What I am suggesting about the natural plant-produced allelochemicals for
use as natural herbicides, is that these chemicals are already in the
environment, and you are just enhancing their effects to be more selective
for the exotics you are trying to control.
The natural herbicides are surprisingly effective, and save a tremendous
amount of effort in controlling the exotic plants, by knocking them back
enough that the natives have the ability to gain some ground.
What is the best routine, is to find the local native plants that produce
the strong natural herbicides, then you are just adding some extra
pro-biotics to weaken the exotics and favor the local natives.

Okay, I was too cryptic. Once more, with more specificity, and I'll drop
this.
I'm not arguing that Matt Rinella's study is incorrect, but that the
results are not surprising, at least not to me. And apparently not to
several of you.
I would modify Karen Adair's comment to the extent that I think Tordon's
effects were at least partially known at that point, but I'll agree
negative effects were not fully understood, and were seen (at the time) as
acceptable because there were few herbicide alternatives. Our views have
changed, but that view reflected the common view of the time that weed
science meant herbicide science. I hope our understanding has developed
beyond that simplistic view.
My view of Integrated Vegetation Management is that it should be informed
by a clear view of what our goal is, no matter what the tool we are using
to intervene in the ecosystem. Herbicides, biological control, grazing
management, mowing, or any other. They all have environmental trade-offs.
For too long we assumed a one time intervention would solve all. Or even
repeated herbicide treatment without consideration of the results. Of
course that was too simplistic. Over-grazing and other factors led to the
problems over time, so a simple one-shot answer was not able to succeed.
Or upon reflection, even realistic.
Herbicides are a tool, like any other. The herbicide tool, and other tools
have improved over time, as has our understanding of ecosystem function. I
read nothing in your response that disagrees with that. It seems to me we
are talking past each other. I think few of us would blithely recommend a
'broadcast Tordon one time and walk away' approach. At least I hope not.
But that doesn't mean Tordon couldn't be an appropriate part of a
integrated program with proper safeguards and attention to the landscape
features. Such as water resources. Also to revegetation issues.
I'm not talking about any particular system of " 'Process flow charts' and
other impressive devices" as you put it. They are tracking tools for
managing data, but they don't result in an improved ecosystem, unless we
understand why we are intervening, how we will follow up, and plan for
monitoring to measure progress to and modify our approach if necessary.
Any tool needs intelligent use. I cut my leg with a chain saw once, but I
still use one. Although much more cautiously.
I certainly agree the an IVM program needs to integrate all relevant
science. A simplistic 'one treatment and walk away' won't do it. It
never did, but for too long folks ignored that fact.
I kept on my bulletin board for a long time "The development of a
scientist; from cocksure ignorance to thoughtful uncertainty".

I hope Tasker will not tax us with generalities, thus tasking us with
trying to figure out what he specifically means.
I am dubious about acronyms, and the catchy labels from which they spring,
as they tend to become buzzwords that either lose their original meaning or
debase the terms of which they are composed. "Process flow charts" and
other impressive devices, when broken down into what they really say, don't
amount to much. The "integrated" aspects of IVM say little or nothing about
ecosystem function and lack specificity with respect to post-treatment
performance.
This is not to say that ecosystems should not be "managed," but herbicides
of any kind tend to be used under the rather simplistic logic, "Weeds bad,
kill weeds, keep killing weeds." That's simply not demonstrably good
enough; virtually all of the cases I have seen rely upon a time-limited set
of general observations (mostly impressive photos) or "surveys" that do not
reveal the long-term implications of ecosystem function. For example, if
one sprays herbicides on weeds, impressive results will follow and be
photographed. Such "data" don't prove anything with respect to ecosystem
function and "health." "Vegetation management" has too long been a
euphemism for killing plants indiscriminately. I would like to see the
details of an IVM program that truly integrates all relevant science.
To truly advance this important discussion, it will be necessary to
establish a tradition of being directly responsive to points made in a
sequence that moves quickly from generalization to theoretical foundations
to evidence, all with lines of relevance clearly evident and assessment,
action, and consequences feedback loops that fully describe the phenomena,
not sell them short. Specific examples which have been sufficiently
researched by independent entities and replicated by other disinterested
(out of the money loop) parties in accordance with the basic principles of
good science. Too much is at stake for the foxes to be in charge of the
henhouses--which should be transparent and open to all for inspection.

APWG:
About six weeks ago I posted a question about whether anyone had noticed a
disease killing Japanese stiltgrass, Microstegium vimineum.
The response and number of questions posted was very interesting and the
hope among resource managers and ecological researchers has been both
palpable and exciting.
Results are in from samples of diseased Japanese stiltgrass that were sent
to labs in Indiana, West Virginia and Maryland. All agree that the
pathogen killing stiltgrass is a fungus in the family, Bipolaris.
There are scientists and other participants in the APWG list that can
probably delve into a discussion of Bipolaris and the range of concerns from
its
potential as a biocontrol agent to its relationship to some extremely
serious diseases of certain food crops. All sorts of issues related to
Bipolaris have already come to light that are far beyond the traditional
training for a dirt forester like me but I would enjoy such a discussion.
Although I am extremely excited to see anything killing Japanese stiltgrass
I am also concerned about some areas of severe mortality I witnessed in
native woodland plants about the same time I was documenting all the
problems
and health issues that stiltgrass was having.
Purple spots and lesions appeared on the leaves of a number of species of
woodland grasses that were similar in appearance to those that were
developing on diseased stiltgrass plants.
Below is a link to a research paper that briefly mentions Microstegium.

Weedy and Invasive Plant Genomics offers a comprehensive, up-to-date
reference on genetic and genomics research in weedy and invasive plants.
Forward-looking in its approach, the work also assesses the areas of
future research necessary to defeat these agricultural pests. This
research-based, scholarly work engenders a further understanding of weeds
and invasive plants, opening avenues for developing more effective methods
of managing them. This volume will be a necessary reference for weed
scientists, agrochemical industry researchers, conservation geneticist,
and plant biologists.

Adventures, May 6 or 7, 2010, although we're already almost full! It's a
popular, first-come, first-served outdoor field trip with limited space, so
register your school today! Once reserved spots are full, you can still
sign up to be placed on a waiting list. Check out www.ohmonth.com for
details. This project is implemented in partnership with Kiski-Conemaugh
Stream Team and many others.
One final item...If you plan to shop online for holiday gifts...If you shop
online for own personal needs throughout the year...If your company shops
online...Consider doing it through www.iGive.com/bio , with Natural
Biodiversity selected as your cause. With this set-up, around 700
participating stores agree to donate a portion of the sales derived from you
to Natural Biodiversity! The donation is at no additional cost to you, in
fact, you can receive member discounts through iGive.com.
My apologies for any cross-postings that may occur. Our aim with this
notice about our current News and Events, specifically our Open House,
premiere issue of *the Leaflet*, and the call for a founding board of
directors is to get these messages out to as many people as possible.
I hope you all had a Happy Harvest!

Scientists race to prevent ash tree's extinction
By Melanie S. Welte, Associated Press Writer -- Thu Oct 8, 7:22 am ET
DES MOINES, Iowa -- Mark Widrlechner is out to save a species from
extinction. It's the native ash tree, and although it provides $25 billion
worth of timber and decorates backyards across North America, an
unstoppable bug has slowly killed millions of trees in 13 states and could
cause the species' ultimate demise . unless Widrlechner is successful.

Integration of phenological observations and relevant models with short
and long-term climatic predictions is crucial to manage ecosystems and
wildlife in the context of a changing climate. The University of Arizona
invites applications from applied climatologists, quantitative ecologists
and ecological modelers for the tenure-track position of Assistant
Professor with an emphasis on Phenoclimatology. This will be an academic
appointment within the School of Natural Resources and the Environment for
an individual who will collaborate closely with colleagues across campus
and particularly with the USA National Phenology Network to provide
leadership in bridging between phenological ecology and applied
climatology.
The successful candidate will capitalize on USA-NPN programs and data
products to develop phenological models, bioclimatic assessments, and
decision support needed to anticipate, manage, and/or mitigate ecosystem
and species responses to climatic variation and change. Opportunities to
collaborate in the environmental sciences abound on The University of
Arizona campus, through such groups as the School of Natural Resources and
the Environment, Institute of the Environment, Climate Assessment for the
Southwest (CLIMAS), Sustainability of Semi-Arid Hydrology and Riparian
Areas (SAHRA), Biosphere 2, the Laboratory of Tree-Ring Research, the
School of Earth and Environmental Sciences, and the BIO5 Institute. A
Ph.D. in ecology, climatology, atmospheric sciences, or a closely related
field is required. We prefer someone with experience that could include
the following areas: climate and/or ecological modeling, time series and
spatial analysis, climate-ecology linkages, evaluating effects of climate
change on ecosystems or wildlife, and/or decision support.
The USA-NPN is an emerging and innovative partnership among academic
communities, federal agencies, and the general public with a mandate to
monitor, understand, and predict the influence of seasonal cycles and
their variability on the Nation?s resources ( www.usanpn.org ). The
National Coordinating Office of the USA-NPN is located on the campus of
the University of Arizona and is co-hosted by the University and the U.S.
Geological Survey. A full description is available by referencing job #
43998 online at https://www.uacareertrack.com . The positions will remain
open until filled, with formal reviews beginning November 13, 2009.
Applications must be submitted online. For more information, contact Dr.
Lisa Graumlich at lisag at cals.arizona.edu .
The University of Arizona is an Affirmative Action/Equal Opportunity
Employer committed to recruiting, supporting, and fostering a diverse
community of outstanding faculty, staff, and students. All applicants who
share this goal are encouraged to apply.
