Are Northfield schools helping to make students climate literate?

Explorer Will Steger  had a commentary in last week’s Strib titled, Make America climate-literate. Here’s an excerpt:

Will Steger, photo by Amanda OdeskiIt wasn’t until 2002, when the Larsen B ice shelf disintegrated from western Antarctica — an ice shelf formed more than 12,000 years ago that my expedition team took a full month to ski across — that the facts of global warming prompted me to take action. In 2006, I decided to establish the Will Steger Foundation, where we support educators, students and the general public with science-based interdisciplinary resources on climate change, its implications and its solutions. Our goal is for educators and students to achieve climate literacy.

If the nation is to address climate change, it must begin with a public that is climate-literate. Starting with our educational system is critical. Teaching and understanding climate change is a process involving scientific inquiry and educational pedagogy; it is not about politics or partisanship. There is virtually unanimous scientific agreement about climate change. Yet due to both the inherent complexity of the topic and the social controversies surrounding it, confusion and doubt often persist. Climate change is now ultrapoliticized in the United States.

I’m curious to know what Northfield’s schools (district, charter, parochial) are doing in the classrooms on this ‘ultrapoliticized’ issue of climate change.  Are our educators using materials like those available on the Steger Foundation’s education page, are they ducking the issue, or doing something in between?

Some personal background:

Trout reproducing, but high nutrients still pose threat

Interns from Dakota County assisted with netting and keeping the fish content with buckets of fresh, cool water until they could be counted and released.Last week, Minnesota Pollution Control Agency (MPCA) stream biologists sampled fish in Rice Creek near Northfield and Trout Brook near Miesville.

Saint Olaf professors and students, along with interns with Dakota County Soil and Water Conservation District (SWCD), aided the biologists with the sampling. Together, the group netted and counted over 600 brook trout and 150 brown trout in five small reaches along the streams.

Of significance, some of the trout counted were 2-inch, young-of-year trout, indicating that stream conditions are adequate for trout reproduction. MPCA stream biologist Brenda Asmus:

I was quite surprised and impressed by the number of healthy adult fish and small young-of-the-year brook and brown trout that we found in these two streams.

Some observations were not indicative of good stream health, however. The group noticed large amounts of filamentous algae, an indication of high nutrient levels in the streams. Asmus:

Small amounts of algae are normal, but high amounts of algae can cause conditions that are stressful to fish. [This is especially the case] during warm summer days when the algae decomposes and competes with trout and aquatic insects for oxygen.

In August, MPCA stream biologists will return to Rice Creek and Trout Brook to sample insects and snails and to collect water chemistry information.

The biologists will be looking for the presence or absence of pollution sensitive fish and insects. Based on what fish and aquatic insects are found, they can get a general picture of the health of the streams. If pollution sensitive species are missing from a stream, it will be rated “impaired” and follow-up work will done to determine the specific problem.

Photo album: ribbon cutting for Lashbrook Park’s new woodland trail

I got this email from Councilor Erica Zweifel earlier this week:

Hi Griff, I am attaching some information and pictures regarding the volunteer awards that I will be giving out at the May 17th council meeting at 7PM.  Please let me know if you would like any further information. Also you are invited to join the ribbon cutting at Lashbrook Park to celebrate the new woodland trail.

I got there for the woodland trail opening and was delighted to meet Helen Lashbrook Olson whose parents owned a farm in the area.

See my album of 10 photos, view the large slideshow (recommended), or slow click on this small slideshow:

Erica’s press release on the volunteer awards (PDF) includes this about the trail opening:

Volunteer Awards 2011St Olaf Environmental Studies majors Mary Coulson, Lisa De Guire, Mary Morris, Katelyn DeRuyter are receiving an award for their work planning and building a woodland trail in Lashbrook Park.

These students worked with The Friends of Lashbrook Park, The Northfield Park Board, and the City of Northfield to design the trail, get approval for their plan and arrange for help with brush and tree removal.

The path is located in the wooded section at the North end of the park. This project is an excellent model of collaboration and community volunteerism.

For more, see Nfld News: Take a walk in Lashbrook Park

St. Olaf students studying social work or environmental studies have been working to develop the new path this semester, designing the trail, weeding the area and picking up garbage. Erica Zweifel, research assistant at St. Olaf and City Council member whose district includes the park, is directing the environmental studies students. She said the project enables students to get out of the classroom and apply what they have learned in the classroom in a practical setting.

Friends of Lashbrook Park has become the Northfield Prairie Partners Chapter according to this March article in the Northfield News, Wild ones take root in Northfield:

Around five years ago, a handful of locals with a mission to keep native plants intact in our city organized themselves into the group, Friends of Lashbrook Park, which later changed over to Prairie Partners of Cannon Valley. Now, with the backing of a larger national organization called Wild Ones, this still small, yet growing group has become Northfield Prairie Partners Chapter of the Wild Ones.

Update 10 am: I got an email from Erica, correcting the info in the above Nfld News article re: the Friends of Lashbrook Park and the Prairie Partners of Northfield:

The Friends of Lashbrook Park is alive and well and is a very separate group from the Prairie Partners of Northfield.  The Prairie Partners did not have anything to do with the path project, but they are responsible for the work being done at GLONA near Greenvale School.  About two years ago two members of the "Friends" group split off because they wanted to focus more on the prairie specific issues and the "Friends" group remains committed to the entire Lashbrook Park.

Chamber staff took off early on (Good) Friday for, um, Earth Day

Northfield Area Chamber of Commerce - Earth DayGiven the US Chamber of Commerce’s position on climate change (Forbes 2009 opinion piece), I found it a little ironic that staff at the Northfield Area Chamber of Commerce took Friday afternoon off in honor of Earth Day, not Good Friday.

In case their Calendar page gets updated, seen the screenshot.

CRWP to host rain barrel building workshops

CRWP rain barrel building workshopJoin the Cannon River Watershed Partnership to learn about runoff and the benefits of using rain barrels for water conservation and gardening.  Go home with a fully assembled 55 gallon plastic rain barrel and the knowledge that you are doing something for clean water.

Through the generous support of the Beim Foundation, CRWP will begin hosting rain barrel building workshops in the cities of Owatonna, Faribault, Northfield, Waseca and Red Wing in 2011. 

At the workshops, participants will learn about water conservation, runoff and how they can reduce the pollution that reaches our lakes and rivers by capturing roof runoff in a rain barrel.  The barrels also provide a free source of water for your outdoor watering needs. We will assemble 55 -gallon plastic drums with the attachments needed to make them rain barrels.

In the Cannon River Wilderness Area, the snow is deep and the water table high

Griff Wigley and Chad Dougherty Chad Dougherty at the Cannon River Wilderness Area Chad Dougherty at the Cannon River Wilderness Area
Chad Dougherty (my mentee) and I went snowshoeing at the east end of the Cannon River Wilderness Area this afternoon. I wanted to show him the site of where Henry Fisk, the Rice County hermit, lived.  In the small protected meadow adjacent to where the Fisk cabin was located, Chad dug down to the ground. You can see that the snow is about 3 feet deep.

Up on the bank just south of the footbridge over Fisk Creek, Chad spotted this area where the water is flowing out of the ground. It appears to be a new flow because the grass sod is still visible as it turns to muck.

Spring Creek: A little boy’s playground

Cannon River Watershed PartnershipStephen in Spring CreekCrayfish hunting, dam building, floating leaf boats, finding mussel shells – these are some of Stephen’s favorite things to do in Spring Creek. Watching the world of water through the eyes of my five-year old son is an incredible experience. He’s learning to love this stream and the creatures in it. These experiences are the ones that will stay with him into adulthood and will lead him to think about how his actions affect and protect water.

As 2010 comes to a close, take a minute to make your year-end gift to the Cannon River Watershed Partnership that will allow us to continue our work on Spring Creek and the many other streams and lakes in the Cannon River watershed.

CRWP donationTo make a donation, go to  the CRWP membership page. You can then make an online donation or print off the membership form and mail it to our office.

Thanks in advance for helping to protect Stephen’s playground!

Filters for Our Water

CRWP - No natural filterWe filter things because we want to prevent something that we don’t want from getting into the thing we are trying to protect. One place this happens is along the shoreline of lakes, rivers and streams. These natural filters help to protect the water by keeping stuff out like dirt, chemicals, fertilizers, and even just too much water.

After rain storms, water runs downhill and picks up dirt, chemicals, animal waste, and whatever else it encounters. As the water hits these natural filters of grasses, perennial plants and trees, it slows down and some sinks into the soil. The stuff the water was carrying settles out in the filter. The runoff that makes it to the lake or stream is then carrying much less pollution and moving at a slower speed so it is less destructive to the banks. All in all natural filters are a great way to achieve clean water.

To learn more about natural filters, also known as buffers, and what is happening in Rice County, visit us at Cannon River Watershed Partnership (CRWP) and check out the following links:

The fight over wind turbine siting moves from Greenvale Township to Rice County

"Township Wind Turbine Discussion" is agenda item #6 at tonight’s work session after the Northfield City Council meeting.

Dr. Gary Carlson, a physician at Allina, has a commentary in today’s Strib titled Wind energy’s ripple effects.

Gary CarlsonI just returned from a meeting of my county planning committee, where we debated the pros and cons of our neighbor’s proposal to put up two 400-foot wind turbines, with the closest about 1,300 feet from our property line. My family lives on a bluff on the edge of Northfield…

Getting up to speed on the science of sound and the medical research related to wind turbines has been exhausting, and in the process I have discovered the dark medical underbelly of industrial-sized turbines. They produce a lot of infrasonic and low-frequency noise.

See:

Scattered across four Rice County townships and capable of producing as much as one megawatt of power each, the six turbines that received preliminary approval would be constructed by Gro Wind LLC. — a company presided over by Leone Medin.  Medin was a co-owner of Medin Renewable Energy, which attempted to construct the 11-turbine Greenvale Township wind farm in Dakota County along with another company, Sparks Energy.

The companies’ plans failed last year after the wind farm ran into heavy opposition from township residents. According to permit applications submitted by the companies to Rice County, the two turbines that did not receive preliminary approval from the Planning Commission would be developed by Spring Creek Wind LLC., co-owned by Anna Schmalzbauer, Medin’s daughter.

Septic system inspections: keeping the lakes clean

Inspecting a septic tankseptic_systemSeptic system inspections have been in the news a lot lately in Rice County.  You can read more about it on the Cannon River Watershed Partnership wastewater page.

Maintenance of septic systems is very important especially if you have lakeshore property.  Having systems that function properly keeps human waste out of the lakes and reduces the bacteria and phosphorus that pollute the water.   To prepare your septic system and cabin for the cold months ahead:

  1. Have your septic tank pumped regularly
  2. Cover the system with a layer of straw or leaves for insulation
  3. Have your furnace cleaned, seal windows, unplug appliances, and winterize any plumbing that won’t be in use during the winter.

(Editor’s note: this was originally submitted to the membership sideblog but I’ve opted to post it to the main blog since Rice County’s septic system inventory has been an issue. – Griff)

From the CRWP wastewater page:

Rice County’s septic system inventory, in which county staff assess if a property’s septic system is an imminent public health threat, has come under criticism at two public meeting over the past couple weeks. This criticism caused the Rice County Board to decide to not apply for additional funding to continue the inventory, for now. See below for Faribault Daily News coverage:

Photos: whooping cranes in the Arb

John Pauley from Prairie Restorations stopped by my office at GBM last week and told me about the pair of whooping cranes that he spotted in the Carleton Arb recently.  There are only 400 of these birds in the wild.

The guy who picks up litter every day around town (he wishes to remain anonymous) pointed out this nest of eggs to me last night. The nest is in the streetscape bushes at 3rd St. and Hwy 3, across from the Quarterback. I assumed they’re Canada goose eggs from looking at the photos on Google images.

If not omelettes, then might your dog be hungry for a snack?

Carlson SEEDS interns Chelsea and Natasha: planting, growing, selling, blogging

It’s not often that someone beats me to a blog post after a community event. But it happened this week.

SEEDS interns - L: Chelsea Wagner; R: Natasha Hegmann; C: housemate Julia ? Basil from the Carlson SEEDS field Thunderhead over the Carlson SEEDS field 
At last Saturday’s Riverwalk Market Fair, I took the photo on the left of Carlson SEEDS interns Chelsea Wagner and Natasha Hegmann (housemate Julia in the center) selling their wares, including the fantastic basil (center) that Robbie purchased from them. What’s SEEDS about?  The St. Olaf Center for Experiential Learning has a page on it:

The Carlson SEEDS (Social Entrepreneurship, Environmental Design, & Stewardship) internship program, founded by Greg and Nancy Carlson ’82, is designed to engage students in experiential learning and discovery that fosters a deeper understanding and appreciation for environmental stewardship and sustainable agriculture.

Natasha’s July 19 blog post, Produce for Sale, chronicles their Saturday, including the game of "How many farmers does it take to set up a tent?" and a visit from a “professional blogging consultant.” Heh.

Chelsea and Natasha are natural born bloggers, telling interesting stories with fun photos on their Carlson SEEDS blog.

The pros and cons of using Roundup for unwanted grass

Laird Stadium at Carleton College Roundup application notice
I’ve been doing a little barefoot running on the luscious green grass at Laird Stadium at Carleton College lately. On Monday, I saw a sign on the gate alerting people that Roundup (Wikipedia entry) had been applied and to “stay off grass until dry.”

Is this a cause for concern? Are there other cost-effective ways to treat a huge area of grass like this? unwanted grass in cracks?

Update 7/16 9 am:  Thanks to the informed comments below, I’ve removed the words “for a healthy lawn” from the blog post title and replaced it with “for unwanted grass.”

I’ve also struck the phrase “a huge area of grass like this” from the second paragraph and replaced it with “unwanted grass in cracks.”

40 days and counting: a floating yellow barrier in the Cannon River with nothing to do

May 28, 2010: floating yellow barrier in the Cannon River Back on May 28, I took this photo of a floating yellow barrier under the 4th St. bridge just below the Ames Mill dam.  Once I confirmed with the police that it had nothing to do with the search for Brittney Landsverk, I assumed that some work on the retaining wall was about to begin.

I got an email yesterday from Adam Solyst at Carlson Capital Management and took this photo late in the afternoon:

July 8, 2010: floating yellow barrier in the Cannon RiverFor over a month now there has been a large yellow floating barrier in the Cannon river between Carlson Capital Management and the Hvistendahl, Moersch, and Dorsey law office (it can be seen easily from the 2nd street bridge).  It started on Carlson’s side in what appeared to be a setup to block off water to the wall and create a dry area in which to work.  But after it was set up nothing happened.  It eventually broke free and floated until it rested in itss current position.  I feel as though whoever put it there originally has forgotten about it.  I can offer no other explanation.

Anyone know what’s up?

Let’s use a Border Collie to solve the geese problem now

shoreline, Ames ParkI optimistically blogged about the Canada geese (AKA ‘sky carp’ or ‘flying rats’) in Ames Park last December: The sky carp problem in Ames Park: the City’s tactics appear to be working.

And then in April, I took this photo of workers removing the fencing along the west side of the Cannon River in Ames Park. I sent this email to City Engineer Katy Gehler-Hess:

Hi Katy, I see the fencing along the Cannon River downtown was removed this morning. The plantings didn’t grow? What’s plan B??

I never got a reply but she evidently forwarded my email to Street/Park Supervisor T.J. Heinricy who wrote:

The fence in Ames park was removed per the recommendation of Bonestroo Inc.  They were the contractor hired to do the install.  I asked them this Spring about the fence removal.  The gentleman that did the install did a very detailed inspection.  The planting’s are doing just fine and are thriving.  That was their assessment.

Alas, the problem is now worse than ever.

geese in Ames Park shoreline, Ames Park shoreline, Ames Park shoreline, Ames Park
I took these photos last night.  The geese use the canoe ramps and the bank next to the Ames Mill fence that’s not city property to enter and exit the river. And the plantings are NOT thriving everywhere as Bonestroo contended. There are many spots that look like this:

shoreline, Ames Park

Nfld News:

City Administrator Joel Walinski said it will take time to see the full effect of the new shoreline, which looks much better than it did two years ago, he said.

I’m extremely doubtful that the current solution will work in two years.  The Nfld News editorial mentioned using dogs, specifically Border Collies. Lots of businesses doing this (example, here) and even the Coalition to Prevent the Destruction of Canada Geese recommends using Border Collies:

Border Collies (BC) are specially trained herding dogs that are extremely effective for keeping geese out of areas where they are considered a problem.  Border collies are the method of choice for large open areas such as golf courses, airports, parks, school ground recreation fields, corporate parks, etc.

Results are immediate. Usually requires aggressive initial use (several times a day for 1-2 weeks) until geese get tired of being hassled and stay away. While the wolf-like gaze of Border Collies is incredibly frightening to geese, these dogs will not harm them or children.

Tearing down the Ames Mill dam might solve the problem but that project appears to be stalled.

So why not get/rent a Border Collie and solve the problem NOW, before DJJD?  Couldn’t the Park & Recreation Advisory Board (PRAB) could take the lead on this initiative?

Another City public meeting/open house, why you should care, and a rant

If you’re concerned about the Cannon River watershed, Spring and Heath Creeks, the health of the Jordan aquifer, and the quality of your drinking water, then you should care about what’s happening with the Surface Water Management Ordinance updates, which will be presented in their draft form this coming Wednesday, June, 9, from 6:30-8:00p in the Community Resource Bank Conference Room.

Psst… an almost-secret meeting at City Hall tonight!

Late last week the City website put up notice for tonight’s  Green Step Cities Presentation meeting.  The notice doesn’t say what it’s about, who it’s for, who’s making the presentation, or anything other than the place and time, which is unfortunate because it may be of interest to citizens.

The Minnesota Green Step Cities program is a State-sponsored program described as  a voluntary program for all Minnesota cities to identify, support, and recognize implementation of a set of sustainable development best practices focusing on greenhouse gas reductions that lead cities beyond compliance and encourage a culture of innovation.

The program is new and will be available this summer;  the purpose of the presentation is to inform the City Council about the program. Tonight’s presentation will be made by Phillipp Muessig of the MPCA.

Since the program’s “best practices” have many implications for land use, I’ve encouraged my fellow Planning Commissioners to attend as well, even though we were not notified/invited.  (I don’t know why not. )

The meeting is tonight (Monday) in the Council Chambers from 7-9p. Wouldn’t it be awful if “too many people” showed up?

Forest tent caterpillars in the St. Olaf Natural Lands: more than usual?

forest tent caterpillars forest tent caterpillars

I was surprised to see the number of trees with forest tent caterpillars (FTC) while walking the St. Olaf Natural Lands trail around the wetland just west of the Tostrud Center yesterday.

The DNR has a 2009 FTC update; the UMN extension has a FTC background page, written in 2000.

Is this a normal occurrence?

Are there endangered dwarf trout lilies in the Arb?

Lance and I went for a hike in Big Woods State Park about a week ago, and the dwarf trout lilies  were in bloom.  After reading a bit about them (here’s the U.S. Fish & Wildlife Service fact sheet) I wondered if there might be some in the Arb or down along the river.

Apparently the dwarf form of the trout lily is ONLY found in three counties in Minnesota, and nowhere else in the world. The foliage of the dwarf trout lilies and the regular trout lilies looks the same and they are found together in the same drifts, so you can’t tell them apart until they bloom.  Trout lilies have six creamy-white tepals (that was a new one for me) and the flower is about the diameter of a nickel. Dwarf trout lilies have 4, 5, or 6 tepals and are about the size of a dime. They also have a slightly pinkish cast.

I went into the Arb and found some trout lilies, but only a few were blooming, and I didn’t see any recognizable dwarf trout lilies.  Does anyone know if the dwarf version has been identified in or around Northfield and/or the Arb?

Here are some more details from the MinnesotaWildflowers blog/website.
