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…

Spring 2012 Central Wisconsin Plant Flowering Dates

Spring 2012 Central Wisconsin Plant Flowering Dates (through April 30th):  Averaged 14 Days Ahead of Pre-2010 Records

  Emmet Judziewicz
Associate Professor of Biology
 Robert Freckmann
Emeritus Professor of Biology


Through April 30th, Central Wisconsin (Marathon, Portage, and Woods Counties) native, weedy, and cultivated plant species have broken their record early flowering dates (most set in 2010) by an average of 8 days.  In turn, 2010 records beat all 1973-2009 records 8 days.  2012 records have beaten all records previous to 2010 by an average of 14.2 days.


Over the 37 year period from 1973-2009, a total of 15 species had flowering records before April 1st in the Stevens Point area, and 86 species before May 1st.  


In 2010 alone, 24 species flowered before April 1st, and 121 species before May 1st. 


And in 2012, 84 species flowered before April 1st, and 252 species before May 1st. 


A total of 263 species are on this list; 112 are native to Central Wisconsin, while 151 are weedy or cultivated.


An important caveat: We admit to a data collection bias this year – we really searched for early-flowering garden records all over town, much more so than in earlier years.


1973-2009 observations were made by Bob Freckmann.  2010 and 2012 observations were made by Judziewicz (about 60%), Freckmann (ca. 20%), with the rest kindly contributed by these colleagues and students: Seth Barthen, Mary Bartkowiak, Alvin Bogdansky, Tracy Feldman, Diane Lueck, Carol Kropidlowski, Angie and Rich Hauer, Rhiannon Kohlmoss, Steve Krause, Noel Martell-Segura, Jeff Morin, and Ron Tschida.


We'd welcome any of your observations for additional early flowering species we have missed (flowering cut-off date: April 30th).

Cassville Bluffs SNA Blitz UPDATE

posted Apr 9, 2012, 2:28 PM by BCW Native Plant Society   [ updated Apr 9, 2012, 2:44 PM ]

Cassville BotanyBlitz Update, 9 April 2012

 FROM:  Emmet Judziewicz, UWSP ;

 I camped at Nelson Dewey State Park and scouted the Cassville Bluffs State Natural Area on March 18-19 and wanted to share info on logistics with you all in preparation for our Botany Blitzs on the weekends of May 11-13 and June 22-23.

Camping at Nelson Dewey State Park

I camped there on the night of Sunday, March 18th.  It is a beautiful campground on a ridge top overlooking the Mississippi River.  Pasque flower was in bloom on Dewey Heights prairie a few hundred yards away.  It was so warm at night that I didn’t need a blanket, and I received some mosquito bites in the mor ning!

Click here for a PDF of a map of the Park with campsites numbered.

THIS CAMPGROUND IS LIKELY TO FILL UP ON JUNE 22-24 and possibly also the weekend of MAY 11-13.  So, I’ve made online reservations at 1-800-372-3607, or online at this site:

For weekend reservations, you must reserve 2 nights (Fri and Sat.), not just 1 night.  The cost (including reservation fee) was $33.70 for each weekend (2 nights per weekend, at a site without an electric hookup).

On May 11-13 I will be camping at SITE 10 (little red car).

On June 22-24 I will be camping at SITE 11 (same car).

Getting to the Cassville Bluffs Parking lot

The public parking space is a tiny driveway on the left side of Sand Lane just PAST the last house.   And I do mean JUST BARELY PAST THE HOUSE – by about 10 feet.  Turn left and you will see a sign that says “Mississippi Valley Conservancy – Cassville Bluffs”.  Park there.  YES, just 10 feet past the house, they will not come out to defend their Castle with deadly force. 

There is no need to go about the drama of getting access to the bluffs through private land on the bluff tops, etc. 

From the parking lot, walk the trail past the gate, on a very convenient and easy to follow hiking / ATV trail that takes you to the top of the prime bluff in 20 minutes.  

It took me just 1.5 hours hiking from car to the far end of the bluff at the far east end of the property, and back to the car.  Do NOT take the RR tracks back, though, there are constant big, high speed trains and very little space to move off to the side.

LOTS was in flower there on March 19 including locally peak Dicentra cucullaria, also Sanguinaria, Claytonia virginica, Arabis lyrata, Viola sororia and a few others.  The fresh Dicentra flowers had rosy pink flush on the legs of the "breeches" - had never seen that before.
