VOTE for Orchid Conservation

posted Aug 5, 2015, 12:56 PM by BCW Native Plant Society   [ updated Aug 5, 2015, 3:59 PM ]

Beginning August 6, you have the opportunity to participate in the Smithsonian’s Summer Showdown to raise the profile of projects taking place right here is Wisconsin. The Smithsonian Environmental Research Center (SERC) is partnering with The Ridges Sanctuary in Door County, WI on their orchid research and restoration project. Please help to raise the profile of this project and other orchid conservation efforts by participating in the Summer Showdown. Details about this competition are outlined below:




The Smithsonian Summer Showdown is a bracket-style voting competition for the public to choose the most amazing thing at or about the Smithsonian. The Smithsonian museums, research and cultural centers, and zoo, nominate contestants in their subject category (art, science, history or culture) and then battle the other contestants on social media with educational and entertaining posts to convince the public that their contestant should win. The public gets introduced to the many aspects of the Smithsonian through a fun competition where they have to choose between contestants, allowing them to learn more about parts of the Smithsonian they didn’t know about before.


SERC’s nominee is the North American Orchid Conservation Center. There are three rounds of voting, and the public can vote online once a day at


Showdown Timetable:

Round 1 (Thursday, Aug. 6 – Wednesday, Aug. 12) – Public votes once in each category (science, art, history, culture). The top three advance. NAOCC needs to be one of the top three for science to remain in the competition.

Round 2 (Thursday, Aug. 13-Tuesday, Aug 18) – Public votes once in each category. The top entry in each category advances.

Round 3 (Wednesday, Aug. 19-Monday, Aug. 24) – Public votes on Final Four.

Tuesday, Aug. 25 – Winner crowned

North American Orchid Conservation


CONTACTS: Kristen Minogue; Heather Soulen


PICK ME: Protecting the world’s smartest plants


ABOUT ME: More than 200 orchid species blossom in North America. Over half are threatened or endangered somewhere. Beautiful, cunning and occasionally deceptive, orchids are also red flags for extinction. When an environment is in danger, orchids are often the first to go. That’s why scientists launched the Conservation Center, a continent-wide network based at the Smithsonian: because saving orchids can hold the key to saving entire ecosystems.

Botany Blitz at Navarino Cedar Swamp SNA (#656) - 15 August

posted Aug 2, 2015, 10:42 AM by BCW Native Plant Society   [ updated Aug 2, 2015, 10:45 AM ]

Botany Blitz at Navarino Cedar Swamp SNA (#656)

    When: Saturday, 15 August at 10:00am. Rain or shine, we will botanize for approximately 4 hours.


    Where: Meet at the SNA parking area. From the intersection of County T and McDonald Road in the Town of Lunds, go east on County Road T 0.75 miles, then continue east 0.4 miles on Deer Lane to a DNR parking lot.


    What to bring: Long sleeves and long pants. The mosquitoes may be bad so bring a head net or bug spray. Waterproof boots may be desired as we will likely find mucky ground or even shallow pockets of standing water. Be sure to bring water and any snacks. We will break for lunch but likely will not come back to the parking lot until the end of the trip. Of course, having your favorite plant guides, a hand lens and a camera will be helpful but not necessary.


   Contact info: If anyone has any questions, they can email me at or call at 608 416-3377.

2013 Spring Flowering Phenology Summary

posted May 1, 2013, 9:03 AM by BCW Native Plant Society   [ updated May 1, 2013, 9:04 AM ]

Dear Colleagues,

Here’s our informal report on spring flowering phenology in the Stevens Point area this year

Through yesterday, we recorded 35 species of plants (both wild and cultivated) in flower through April 30th, versus 252 species in flower last year by that date.

On average, plants have flowered 5-5.5 weeks later than last year (mean, 35 days; median, 38 days).

Click here to view spreadsheet (look at Sheet 1 in particular) summarizing early flowering records in our area from 1973-2013.   We make no claims to completeness for data coverage and survey effort for every year, but would say that the 2012 and 2013 surveys are quite comparable in terms of the survey efforts that we put in.

Judziewicz made most 2010, 2012, and 2013 observations, while Bob Freckmann made all 1973-2009 observations and many 2010-2013 observations.  These folks also contributed observations: Seth Barthen, Mary Bartkowiak, Alvin Bogdansky, Aaron Fahlstrom, Tracy Feldman, Diane Lueck, Carol Kropidlowski, Angie and Rich Hauer, Rhiannon Kohlmoss, Steve Krause, Noel Martell-Segura, Jeff Morin, and Ron Tschida.

Common Mosses of the Northeast and Appalachians

By Karl B McKnight, Joseph R. Rohrer, Kirsten McKnight Ward & Warren J. Perdrizet

Princeton University Press, 2013, $24.95


This is the first book to help amateur naturalists recognize 200 common mosses of the Northeast and the Appalachian Mountains. With just this field guide, a hand lens, and a spray bottle--no microscopes necessary--readers will be able to identify many of the common species of mosses growing in the region's backyards, parks, forests, wetlands, and mountains. The area covered includes the northeastern quarter of the country from Maine to Minnesota and down the Appalachian chain to North Carolina and Tennessee.  At the heart of this guide is an innovative, color-tabbed system that helps readers pick out small groups of similar species. Illustrated identification keys, colorful habitat and leaf photos, more than 600 detailed line drawings, and written descriptions help differentiate the species.


The book is available from the publisher (, as well as many bookstores that carry field guides, and of course (

Six New Wisconsin Plants in 2012

posted Sep 4, 2012, 7:40 AM by BCW Native Plant Society   [ updated Sep 9, 2012, 8:01 PM ]

Six new species to the flora of Wisconsin, and where to find more


Emmet J. Judziewicz and John Zaborsky


Submitted 29 August 2012


With global warming really beginning to kick in, we can expect to see more heat-tolerant invasive plants to appear in Wisconsin.   Such has been the case during the first ten years of the 21st century, and in particular during 2012.  Here are some new records for our state, in chronological order.  Click here for PDF that includes photographs.


Fairgrounds grass (Sclerochloa dura)


This Eurasian grass, tolerant or heat, salt, and trampling, was first collected in Wisconsin by University of Michigan Botanist Richard K. Rabeler in 2001, in Rock and Walworth Counties:  It had been collected many times in the Chicago regions since 1992 and it was only a matter of time until it reached Wisconsin.  As the common name indicates, it often appears first at county and state fairgrounds:


Plains bluegrass (Poa arida)


This is a salt- and drought-tolerant western U.S. species that was first collected in Wisconsin in heavily salted ditches along I-94 in Kenosha and Racine Counties by Illinois botanist Gerould Wilhelm in 2008.  Wilhelm had previously detected it frequently, starting in 1991, along interstate highways in the Chicago Region.  It is an early-flowering bluegrass (like Poa annua), but has a pale, ghostly color.  Like Fairgounds grass, it will probably move north in Wisconsin in the coming years.

Small hawksbeard (Crepis pulchra)


This Eurasian member of the sunflower or composite family (Asteraceae) was first collected along the active, north-south running railroad along the east bank of the Mississippi River a few miles south of Cassville, Grant County, by Neil Harriman and Tom Eddy.  Neil identified it at the University of Wisconsin-Oshkosh herbarium.  Small hawksbeard is present in Illinois and Indiana but is rare in both states.  The Cassville railroad site produced two other state records in 2012

Windmill grass (Chloris verticillata)


Windmill grass (Chloris verticillata), a native of the southern U.S. that has recently become weedy in northern Illinois, was first collected as a weed at Muscoda, Grant County, on 15 August 2012 by Emmet Judziewicz, along a paved footpath in park on the banks of the Wisconsin River.   It looks like a pale green, prickly crabgrass due to its finger-like spikes of awned spikelets.


Small white morning glory (Ipomaea lacunosa)


Small white morning glory (Ipomaea lacunosa), a southern U.S. species, was first collected at the “Cassville railroad site” in Grant County on 19 August 2012 by John Zaborsky and Emmet Judziewicz, and photographed (below) and identified by Zaborsky.  It has heart-shaped leaves, and, as its common name suggests, small white flowers.  This species is native in the northern ¾ of Illinois, the Wisconsin collection representing a northern range extension of about 100 miles.


Five-hook bassia (Bassia hyssopifolia


On the same morning, John and I also found this Eurasian member of the amaranth family (Amaranth family, including the old Chenopodiaceae) in the same locality as small hawksbeard and small white morning-glory.   It was locally common and almost formed a sterile 0.75 m “hedge” in the railroad ditch in places; the flower buds were just beginning to appear.   The USDA web site has this Eurasian weed as rare in South Dakota, Iowa, and Kentucky in the Midwest, commoner as a weed in the western U.S.


Where we might expect to find additional new Wisconsin plant records


Clearly, more heat- and drought-tolerant Eurasian and southern and western North American species may be expected to be found in Wisconsin, especially in disturbed areas such as heavily salted highway margins and railroad rights-of-way in the far south near the Illinois border.  A week spent carefully botanizing such habitats would be productive, especially later in the summer when these species tend to bloom.  The Cassville railroad site had characteristics that proved conducive to these new invaders: heavy train traffic, on a south to north route, apparently non-herbicided margins in most places, and a ditch and small embankment on the outside of a curve, where gravity would be expected to dislodge hitchhiking seeds.  Result: Three state records, and we did not survey it completely…
