Subject: [IPAW] frog deformities and pesticides

Hello All:

There has been some good primary research by Tyrone Hayes of U of California - Berkley that demonstrates a link between atrazine and increased vulnerability to the trematode parasites that naturally infect frogs. Atrazine has lots of rather alarming impacts such as reduced sperm production in fish, amphibians, and laboratory rodents and is associated with impaired fertility and low sperm county in humans.

Dr. Hayes has focused on atrazine and does not make any link to herbicides that we all know and love (well, maybe not love, but at least use).

You can read more about his work on his web site - http://www.atrazinelovers.com/m0.html

He has a lot of great information there including impacts on plants and endangered species.

I agree with Nancy Braker's unstated point that, while this new study of
dragonfly larvae munching tadpole legs is interesting and may explain
some portion of deformities, this study may distract many from more
important issues of amphibian declines in general. We need only to look
at the spectacular and largely unexplained disappearance of the formerly
abundant northern cricket frog (Acris crepitans
<http://dnr.wi.gov/org/land/er/biodiversity/index.asp?mode=info&Grp=21&SpecCode=\
AAABC01010>,
aka Blanchard's cricket frog) to give us a jolt. Nancy's link
(http://atrazinelovers.com/) points to many peer-reviewed papers in
respected journals linking atrazine and similar pesticides to these
declines. Endocrine-disrupting pesticides are now everywhere. Anyone
reading this is likely to have some in their tissue. Here are three
links from USGS supporting this.

http://toxics.usgs.gov/highlights/total_environment.html

http://co.water.usgs.gov/midconherb/html/herbmidrivers.html

http://ks.water.usgs.gov/pubs/fact-sheets/fs.181-97.html

This last link states "The deposition of herbicides in areas where
herbicide usage is low, such as the Great Lakes, presents a different
but potentially serious, long-term problem. For example, one of the
sampling sites was located on an island in the northwest part of Lake
Superior, far from the Corn Belt. The dominant source of atrazine to
Lake Superior and the only source on the island site is atmospheric
deposition. Using data from this study, the estimated annual wet
deposition rate for the period of the study on Lake Superior was about
12 (�g/m2)/yr." (micrograms per square meter per year).

Virginia,

More well known authorities weigh in on the frog study. Gail Epping Overholt formerly of ALNC, asked, "Who is funding the study?" I don't mean to bother you, but if folks are interested they should read all this.

Thanks.

Subject: RE: Penn sedge control hspaul@...
Send Email

TNC here in WI manages several properties with dense stands of Pennsylvania Sedge on it. Although a native species and an important component of several habitat types, we too observe that the species is present in such dense stands such that it prohibits other native species from staking their claim. Anecdotally we have observed several times that the "sedge mat" is broken up and other native species take advantage after a soil disturbance event, particularly of note, after a timber harvest when equipment has caused some scarification.

We and others have also speculated for a long time, but haven't take steps to scientifically demonstrate in WI, that the timing of RX burning that we typically conduct here in WI is advantageous to Penn Sedge, and that the repeated burns during the dormant season favors it's density.

Some observations of some burning that TNC is conducting in Michigan during the summer months (yes, apparently very slow moving and smoky burns) is in effect breaking up the penn sedge mat and giving opportunity to other native species to flourish. The following is from a coworker with TNC in MI and they have some permanent photo points and plots documenting the effects.

"P. Sedge, summer burns have proven effective in breaking-up (punching holes in a dense sedge matt. Generally, lack of fire can lead to very dense P. sedge mats in some areas, which inhibits other native plant growth.Early spring burns (March, early April) does NOT cause a beak-up of sedge matt, appears to actually help it. Late spring burns, dependent on intensity and severity, can start to break-up the sedge matt, but also can help it out (again, dependent on intensity/severity, and the aggressive response of other native prairie plants, especially the grasses). Summer burns (May, June, July, August), while often low intensity, can have moderate/high severity, and can have a very long residence time, can break-up the P. sedge matt, and allows other plants to "intermingle" within the sedge matt. Repeated burning continues to break-up this sedge matt, to where the P. sedge is still a component of the vegetation diversity, but not the dominant one, or one that is inhibiting other plant diversity."

My general reaction is that we should be seeking to find the right alternate management practices to help other natives compete with Penn Sedge, rather than specifically trying to kill it with herbicides. Herbicides may work at a small scale, but at a large scale I believe the desired effects will have to come through fire management.

The Disappearing Male is a [44-minute] CBC documentary about one of the most important, and least publicized, issues facing the human species: the toxic threat to the male reproductive system. The last few decades have seen steady and dramatic increases in the incidence of boys and young men suffering from genital deformities, low sperm count, sperm abnormalities and testicular cancer. At the same time, boys are now far more at risk of suffering from ADHD, autism, Tourette's syndrome, cerebral palsy, and dyslexia. The Disappearing Male takes a close and disturbing look at what many doctors and researchers now suspect are responsible for many of these problems: a class of common chemicals that are ubiquitous in our world. Found in everything from shampoo, sunglasses, meat and dairy products, carpet, cosmetics and baby bottles, they are called "hormone mimicking" or "endocrine disrupting" chemicals and they may be starting to damage the most basic building blocks of human development.

July Door County Invasive Species Team Bulletin . . . . Please share

�

�� It must be summer, everything is happening at the same time.� Fishing, jetskiing, hiking, gardening, camping . . . .� Multiple activities mean multiple opportunities to interact with invasive species issues.� This bulletin contains a brief overview of relevant summer topics including information about the dangers of moving firewood, the poisonous effects of wild parsnip and spreading the word about the importance of clean watercraft and clean practices while enjoying our county�s bountiful waters.� See below for the Calendar of Events to find out when and where you can learn more about the simple steps you can take to protect yourself, your pocketbook and Door County�s natural beauty.

�

Donated Hours Match Critical Grant Dollars

�

�� Thank you!� Logged volunteer hours have been pouring in.� Well over 600 hours logged on terrestrial species so far this year.� Your positive actions are worth tens of thousands of dollars for the DCIST effort.� Your help is invaluable.� Until we secure stable, annual funding for our multifaceted programming, DCIST relies entirely on grants and donations.�

�

�� As summer turns on, our grant focus is turning to wetland and aquatic work.� Keep up the great work and keep on logging your hours.� Because of your helpful suggestions, the Volunteer Logsheet for donated time is now easier to find from the Home Page of the DCIST website (just click on Forms).� To help you stay current, the Calendar of Events is now accessible directly from the Home Page too.� We want the website to be as user friendly as possible, please keep the suggestions for improvement coming.

�

NOW BLOOMING

�

Wild Parsnip � We need your help!!

�� The Door County Invasive Species Team needs your help.��A poisonous invasive plant known as wild parsnip or poison parsnip is steadily spreading into our county.� It is blooming now, which is the easiest time to spot it.� Wild parsnip is a biennial plant that looks a lot like dill weed when the yellow flowers bloom.� If your skin comes in contact with the sap from the plant and is exposed to sunlight, you will suffer burn like blisters.��See attached photos.

�

�� Wild parsnip�loves the open sun of roadside ditches and its seeds are�all too easily spread by mowing machines.��We need keen eyed citizens to report sightings of wild parsnip so we can do our best to eradicate new populations before infestations get out of control.� Please visit the Door County Invasive Species Team website at http://map.co.door.wi.us/swcd/invasive/default.htm�� Click on 'Report an INVASIVE'� to report your findings.

�

�� The key to control is preventing it from seeding, which means getting the plant before the flowers mature.� Wild parsnip has a taproot that can be sliced with a shovel.� In soft soil or after a rain, whole plants can be pulled out.� If you are working around wild parsnip avoid getting the juice on your bare skin by wearing gloves, long sleeves, long pants etc.� If you suspect that you have gotten some of the juice on your skin wash the area thoroughly with soap before it is exposed to the sun to avoid the reaction.

��We can keep this invasive under control if we identify where it is growing.� Most of the known populations in Door County are relatively small and thus manageable at this time.� It is critical to report any new satellite populations.� Please be�on the look out for this yellow flowering plant.� If you would like up close experience identifying and/or controlling this plant please join us for a demonstration workday.� The next wild parsnip control workparties are scheduled for Tuesday July 7 and Thursday July 9 starting at 9 am each day.� Meet at the Pines II Tavern at 980 County DK (old Highway 57) south of Namur.� Your help would be greatly appreciated.� Please dress appropriately.

If you have any questions or concerns please contact either:
David Puhl at 920 746 2484 or at dpuhl@...��

��

Dames Rocket � flower imposter

�� Dames rocket, a.k.a. dames mustard, is in full bloom at this time as well.� Primarily purple, but also blooming in shades of pink and even white, dames rocket masquerades as native woodland phlox.� Similar in color and stature to phlox, dames rocket is not the plant it appears to be from a distance.� Take a closer look, as a prominent member of the mustard family; the flowers of dames rocket have 4 petals.� Phlox, a wonderful native, has flowers with 5 petals.� An easy way to remember this: phlox has 5 letters and 5 petals.

�

�� Dames rocket is an invasive plant! �The flowers present pretty colors, but that is where the �pretty� ends.� Sun loving, but heartily shade tolerant, dames mustard is an aggressive threat to our native woodlands.� A short lived perennial, dames mustard can flower (and produce its copious seeds) in consecutive seasons.� Treat dames rocket like garlic mustard � pull or dig (get the majority of the root) while minimizing soil disturbance and secure flowers and seed heads into sealed garbage bags (label bags) and landfill or destroy by burning.

�

�� Unfortunately, this invasive weed is still often contained in �wildflower mixes�.� It produces tremendous amounts of seeds and easily escapes to natural areas.� When gardening, please make certain to plant native or non-invasive exotic plants (How about native phlox?).� Keeping the weedy species out of your gardens will help keep them out of our natural areas!

�

Firewood Movement

�

�� It is camping season, an appropriate time to remind everyone not to move firewood from place to place.� Every tree species has pests and diseases that are easily moved on firewood.� The overall health of our forests is dependent upon our good stewardship.� Support our local economy and help keep our forests healthy � remind friends, neighbors and visitors to buy firewood from LOCAL vendors.

Subject: Invasive Species Experts Directory

This is to alert everyone to the availability of a national experts
directory developed by the ANS Task Force to assist with identification
of and rapid response to invasive species.  Tier 1 experts are public
contacts -- the folks in each state you should contact if you find
something that may be invasive.  Tier 2 contacts are available to
registered users -- these are the folks who can provide expertise in
identifying species and responding to new invaders.

The system currently includes more than 30 Tier 1 and more than 65 Tier
2 Experts.

If you have relevant expertise and are interested in being listed in the
system, please contact Rochelle.Sturtevant@....

If you know someone who you think should be listed, please forward this
message to him or her!

Dear Interested Stakeholder:

You are being contacted because we need your help in preventing the spread of invasive plants, insects and diseases in our urban and community forests. Invasive species have left our communities with exorbitant control costs, decreased economic, environmental and social benefits, and decreased biodiversity.

With direction from the Wisconsin Council on Forestry and the Wisconsin Urban Forestry Council, an advisory committee of 21 representatives from the green industry, government agencies, municipalities, non-profit organizations and trade associations came together to develop the Draft Wisconsin�s Urban Forestry Best Management Practices for Invasive Species. Once finalized, the adoption of these practices will help to protect, maintain and enhance Wisconsin�s urban and community forests.

To help make the BMPs practical yet effective, we need your feedback. A survey has been posted on the Wisconsin Council on Forestry website where you can view the draft manual and provide comments and recommendations. Please take time to review the manual, complete the survey, and share this email with your colleagues. The draft manual and survey will be posted for public comment from June 30^th through July 30^th. The finalized BMPs will eventually be posted on the Wisconsin Council on Forestry website. Thank you!

To view the Draft Wisconsin�s Urban Forestry Best Management Practices for Invasive Species and take the survey, please visit: http://council.wisconsinforestry.org/invasives/urban/

If you have any questions or concerns, please contact Olivia Witthun, UF BMP Project Manager, at Olivia.Witthun@... or 920-303-5421.

Some good questions to ask onn JUL 23:

Since within Dane County herbicides are being used in urban parks (municipal, county and state), some so small that they are surrounded by residences:

* In which North American cities have certain or all herbicides been banned?

* Which Dow herbicides have been banned? why?

* How does the City of Middleton manage its parks for invasives without the use of pesticides?

And so forth.

There are several pesticides that have been banned in Canada cities and a few less here in the US. Lets not forget that its the Chemical industry that once heralded the perfect pesticide, DDT and we all know how that turned out. This is not to say that Herbicides are not a valuable tool in restoration practices but they're indeed poisons and only should be used according to label instructions and when other less intrusive practices have been exhausted.

Subject: EPA Agrees to Crack Down on San Francisco Area Pesticides naturalimages11
Send Email

San Francisco Chronicle, July 1, 2009
EPA ready to settle Bay Area pesticide suit
By Jane Kay

The U.S. Environmental Protection Agency announced Wednesday a proposed settlement of a lawsuit that could result in scrutiny of how dozens of dangerous pesticides affect threatened and endangered species living around San Francisco Bay.

If the EPA decides to settle the suit filed by the Center for Biological Diversity, it would require reviewing the health effects of 74 pesticides on 11 imperiled species by June 2014.

The pesticides can endanger wildlife by direct contact or by destroying the animals' habitat or food supply.

Some of the problem pesticides, the suit said, are malathion, an insecticide suspected of harming the delta smelt and the California tiger salamander, and sodium nitrate, a hazard to the San Joaquin kit fox, the Alameda whipsnake and San Francisco garter snake.

Other species that would receive review under the proposed settlement are the salt marsh harvest mouse, California clapper rail and California freshwater shrimp. Insects are the bay checkerspot butterfly and the valley elderberry longhorn beetle. A fish is the tidewater goby.

Scientists say methyl bromide, an agricultural fumigant used on strawberries and tomatoes, can poison small mammals and reptiles. Permethrin, a common insecticide used in homes and croplands, can run into waterways and hurt crustaceans and insects at the base of the aquatic food chain, they say. Chlorpyrifos, an insecticide banned in households but available to apple and grape growers, threatens a broad range of species.

The environmental group filed the lawsuit in 2007 in U.S. District Court in San Francisco, where the group has offices.

The suit alleges that the EPA failed to comply with the Endangered Species Act. The act requires federal agencies to ensure that their decisions don't hurt imperiled species by consulting with scientists at government wildlife agencies such as U.S. Fish and Wildlife Service.

Yet, according to the suit, the EPA hadn't sought review of the pesticides that it registers, and some of the pesticides already registered by the EPA did, indeed, damage 11 species of mammals, birds, reptiles, fish and insects in the Bay Area.

The EPA made the announcement Wednesday through publication in the Federal Register. The EPA's public affairs office in San Francisco referred comments on the matter to the headquarters in Washington, where no one was available for comment.

The EPA is accepting comments on the proposed settlement agreement for 15 days, and then will make a decision whether to agree. To become final, the settlement must be signed by a judge in the court where the suit was filed.

Environmental groups are expected to favor the agreement while chemical manufacturers are expected to oppose it.

The Bush administration had eliminated the section of the Endangered Species Act that requires that federal government agencies consult with wildlife scientists on pertinent decisions. But the Obama administration reinstated the rule.

Send Email

Hello,
We have several large clones of aspen resprouts on a remnant prairie and an
adjacent old field.  Does anyone have experience using Krenite (fosamine) to
control aspen resprouts?  Some land managers have told me there can be an impact
to herbaceous vegetation despite the claim that Krenite is a bud inhibitor and
only affects brush.  Others have said it works well on brush and has no
detectable impact on the surrounding herbaceous layer.  I'd like to be certain
of all potential impacts before foliar spraying over high quality vegetation.

The label says Krenite can be used to treat cut stumps. This would minimize any
collateral damage but is it really effective?  Any advice would be appreciated.

Thanks,
Lars Higdon

Fungus Tapped to Take on Kudzu
By Jan Suszkiw
July 16, 2009

Kudzu, "The Vine that Ate the South," could meet its match in a naturally
occurring fungus that Agricultural Research Service (ARS) scientists have
formulated as a biologically based herbicide.

By one estimate, kudzu spreads at the rate of 150,000 acres annually,
easily outpacing the use of herbicide spraying and mowing, as well
increasing the costs of these controls by $6 million annually.

But in Stoneville, Miss., ARS plant pathologist Doug Boyette and colleagues
are testing a fungus named Myrothecium verrucaria, which infects kudzu with an astonishing speed of its own. In fact, the fungus works so quickly that kudzu plants sprayed with it in the morning start showing signs of damage by mid-afternoon, according to Boyette, with the ARS Southern Weed Science Research Unit in Stoneville.

He first began working with M. verrucaria in 1998, when a Louisiana Tech
University scientist furnished him with isolates from diseased sicklepod
specimens. In greenhouse experiments, spray formulations killed 100 percent of kudzu seedlings and 90 to 100 percent of older plants in outdoor trials. Myrothecium also worked its anti-kudzu magic under a wide range of conditions, including the absence of dew.

Additionally, host-range tests in 2005 showed that Myrothecium caused
little or no injury to many of the woody plants known to occur in
kudzu-infested habitats, including oak, cedar, pine, hickory, pecan,
sassafras and blackberry.

A few companies expressed interest, but only if the fungus' production of
toxins called trichothecenes could be reduced or stopped. Boyette's group
examined several approaches, settling on a method of growing Myrothecium in a fermenter on a liquid diet instead of a solid one. Not only did this stop trichothecene production or reduce it to acceptable levels, the method also extended the fungus' shelf life and potency under field conditions.

Besides kudzu, Myrothecium also showed potential as a pre-emergence
bioherbicide, controlling purslane and spurge in transplanted tomatoes.

Read more about the research in the July 2009 issue of Agricultural
Research magazine.

ARS is the principal intramural scientific research agency of the U.S.
Department of Agriculture.

Predators battle bugs, become pests themselves By SUDHIN THANAWALA (AP) - 1 day
ago SAN FRANCISCO - Imported insects have been deployed as foot soldiers in the
fight against invasive bugs and plants that cause billions of dollars in damage
each year. But some of those imports are proving to be pests themselves that
upset the balance of nature and threaten native species.

Earthworm Invasion as the Driving Force Behind Plant Invasion and Community Change in Northeastern North American Forests

Abstract:

Identification of factors that drive changes in plant community structure and contribute to decline and endangerment of native plant species is essential to the development of appropriate management strategies. Introduced species are assumed to be driving causes of shifts in native plant communities, but unequivocal evidence supporting this view is frequently lacking. We measured native vegetation, non-native earthworm biomass, and leaf-litter volume in 15 forests in the presence and absence of 3 non-native plant species (Microstegium vimineum, Alliaria petiolata, Berberis thunbergii) to assess the general impact of non-native plant and earthworm invasions on native plant communities in northeastern United States. Non-native plant cover was positively correlated with total native plant cover and non-native earthworm biomass. Earthworm biomass was negatively associated with cover of native woody and most herbaceous plants and with litter volume. Graminoid cover was positively associated with non-native earthworm biomass and non-native plant cover. These earthworm-associated responses were detected at all sites despite differences in earthworm species and abundance, composition of the native plant community, identity of invasive plant species, and geographic region. These patterns suggest earthworm invasion, rather than non-native plant invasion, is the driving force behind changes in forest plant communities in northeastern North America, including declines in native plant species, and earthworm invasions appear to facilitate plant invasions in these forests. Thus, a focus on management of invasive plant species may be insufficient to protect northeastern forest understory species.

August 2009 Door County Invasive Species Team Bulletin

�

Emerald ash borer confirmed in Brown County

�

By now, most of you have received the troubling news that emerald ash borer (eab)---destroyer of all true ash trees has been confirmed in downtown Green Bay.� An adult eab was found on one of the purple sticky box traps in a parkway along the Fox River.� Wisconsin Dept. of Ag and WDNR personnel are in the process of assessing the threat.� The initial press release is attached.

For more info, please check out:� http://emeraldashborer.wi.gov/� or� http://dnr.wi.gov/invasives/firewood/

�

So please, utilize wood products responsibly. �Firewood has potentially devastating consequences to the trees in all of our landscapes.� Encourage your friends and neighbors to stop moving firewood around.� All tree species have pests and diseases that are easily moved from place to place hitchhiking on firewood.�

A good rule of thumb:� Firewood should never cross more than one county line.

A good mantra:� Burn It Where You Buy It.�

�

Wild parsnip sightings � keep �em coming

�

Thank you to those of you who have been reporting patches of wild parsnip.� DCIST is building a working map of known locations that will help us (and the roadside mowers) minimize the spread.� This poisonous weed is relatively new to Door County and numerous small and isolated (for now) roadside infestations stand a real good chance of eradication if we act!�� We need your help to accomplish this.� (See the July �09 DCIST Bulletin).

�

Keep in mind that the sap from this plant, once activated by the UV light of the Sun, will cause a chemical burn on the skin.� Wear appropriate clothing and gloves and wash immediately after working with this plant.� (If careful, it is entirely possible to work with wild parsnip and not encounter the plants� juices).

�

Poison parsnip is definitely in the seeding phase, especially if it is growing in a dry area.� If you encounter individual or small clumps of plants and have the means to do so, digging (i.e. slicing the taproot), pulling up the plants or cutting off the seed heads and disposing of them in the garbage or burn barrel (so that the seeds are destroyed) will help slow the weed�s exponential growth.� Note where you found it this year, as follow-up next year will be needed.� Please report any sightings/work done on the DCIST website:� http://map.co.door.wi.us/swcd/invasive/InvasiveForm.htm

Once seed heads are drying out and dropping seeds, it is best to stay out of the patch.� Digging or spraying rosettes can be done in fall or spring.

�

#####� Special kudos to Peter Sigmann of Little Sturgeon who has not only reported several formerly unknown roadside infestations, but has been actively cutting and collecting seeded plants to curb their spread.� The simple stewardship efforts of Door County residents like Peter are what truly make this a better place to work and play.� #####

Door County Invasive Species Team August Meeting:

Shoreline Management Forum

Keeping Our Lake Shoreline & Wetlands Healthy and Weed-free

�

2pm

Monday August 10, 2009

Collins Learning Center

Crossroads At Big Creek

2041 Michigan Avenue

Sturgeon Bay, Wisconsin

�

Create any disturbance in the natural world and invariably it is the weedy, aggressive species that move in quickly.� The low levels of Lake Michigan have exposed plenty of lakebed to the relatively rapid growth of vegetation.� Most of the vegetative growth on our shoreline is healthy and beneficial.� Unfortunately, many places have experienced the proliferation of invasive plants.� Without stewardship action, undesirable plants continue their biological invasion.

�

Join a panel of DCIST Team members including experts, agency staff and neighborhood leaders as they present overviews and summaries of their ongoing efforts to keep our various shoreline and wetland environments healthy and free of invasive weeds.� We will discuss regulatory aspects to shoreline and wetland management, Best Management Practices (BMPs) and learn about 2 new invasive plants to watch out for and eradicate before they get a foothold on your shoreline or in your wetland: lyme grass in dune environments and cirsium palustre (european swamp thistle) in wet woods and wet soil shoreline areas.

�

As always, this informational meeting is free and open to the public.� Questions?� Please contact the Door County invasive Species Team at 920.746.5955� or� dcist1@....

Please post/distribute this flier where appropriate (websites, bulletin boards,
e-mails).

Narrowleaf bittercress (Cardamine impatiens) is a new, invasive plant species to
Minnesota.  Since there are a limited number of narrowleaf bittercress colonies
in Minnesota, eradicating this species is the objective.  Narrowleaf bittercress
has been found in several parks along the Mississippi.  Early detection and
rapid response will stop this species before it spreads.

The flier is also posted on our website:

Subject: non-native Pokeweed??? driftlesslan...

Hi All,

I've found a plant which raises substantial concern that someone should look into.

We have been working in Monona Woodland Park (on Monona Drive) for a number of years. There has always been a population of what I believed to be Phytolacca americana (it is an occasional native here in SW WI, weedy but not extremely so).

As management (Rx fire, GM control, brush & canopy thinning) has progressed, we've noted an overwhelming explosion of the plant, to the point where it is a community dominant. Upon seeing this, and not having observed this "invasive" behavior before, I checked the web.

It turns out that Hugh Iltis collected a non-native relative, Phytolacca acinosa, in Olin Park in 1971. The following is from the Flora of North America...

The only collections of Phytolacca acinosa we have seen from the flora are those made by Hugh H. Iltis and others at Olin Park in Madison, Wisconsin (WISC; three collections, the earliest 1971, the latest 1986, photographs 1996). The plants were reported to be scattered to abundant, with many seedlings or young plants of all sizes, and were found in deep shade in a deciduous forest where the species had persisted for about 25 years.

I believe it is also known from AZ and HI. It apparently has been studied/used widely for medicinal properties.

P. acinosa varies from P. americana in that it has berries with ridges rather than smooth skin. While I was last at the park when the berries were slightly under-ripe, it certainly appears that this population is the non-native. Is there a Madison resident who could visit the park in the upcoming weeks to make a positive ID?

I have since found what very much appears to be the non-native in rural Iowa County. I'll know more as these fruits ripen.

Based on the aggressive behavior we've observed at the park and the likely spread to surrounding areas, I believe this plant to be a potential problem.

Anyone else have insight?

I have seen the population at Olin Park. I took the attached photo there on June 29th (sorry I couldn't figure out how to upload it to the Yahoo group). To me this species is pretty distinctive from our native one, enough so that I realized it was something "different" before I figured out it was a pokeweed. I think the very upright flower/fruit structures and over-all more upright appearance of Phytolacca acinosa differentiate it pretty clearly from our native P. americana, which has droopy flower stalks and a more spreading structure.

Regarding sightings, I believe Mike Anderson of Biologic has seen it on clients sites in Iowa county as well.

Jesse, if you are talking about taking a look at the plants at Monona Woodalnd, I might be able to do that. I live less than two miles from there and pass by it a couple days a week. Let me know if you want me to take a look.

Peggy and I took the attached pictures in Monona Woodland Park this afternoon. The unripe berries are definitely ridged, but the ripe berries appear to be smooth. You can't really see it in the one picture that has both. Also, the flower/fruit structures are laying over as Frank said. We are guessing that it is the native pokeweed. However, as Jesse said, it is very invasive. In less than 3 years, it has taken over about 40% of the park (8-10 acres). Maybe Woodland Park can become the Invasive Species Laboratory Park for Research. We seem to catch everything in there.

Hello all, just an FYI.
The Knotweed is in full bloom and now until first frost is the best time to
spray with Milestone VM.  Use 1/2 oz per gallon water with a little surfactant.

let all of us know your results next spring.

What kind of time frame are we looking at before ripe fruit is formed?

I can try to round up the usual suspects.
