The Lake Wingra Watershed--A Field Trip

.
To fit within 2.5 hours, we will focus on...
  • A healthy natural waterway
  • Stormwater channels of various kinds, including one badly deteriorated, and a stormwater basin
  • A sick urban stream
  • Rain gardens
...stopping at five locations shown on the map...

AK = Toki Shool
WP = Westmorland Park (lunch stop)
Samp = water sampling location at Wingra Park
----- = route of water from Odana Pond to Lake Wingra

Lincoln Elementary School is a leader in outdoor education

.
Recently, the Friends of Lake Wingra met with Clare Seguin, a Lincoln science teacher who is interested in applying for a grant from FOLW.

The grant would cover expenses for installation of a rain garden--mostly for plants purchased wholesale from Agrecol, Inc.  Up to $4,000 in funds are available from FOLW, with an application deadline of Jan. 5, 2015.

Clare said she could incorporate rain garden construction into her classes.  Students would put the plants in the ground.

We discussed how a rain garden with native plants could introduce students to concepts of biodiversity.  Students can use inexpensive cameras to "capture" insects visiting fall flowers in the garden.  Then they can make scrapbooks of insect photos, and look up life-cycle details on the internet.

Plans for harvest of aquatic weeds in Vilas Lagoon

.
Dane County Parks will be doing their last harvest in the Vilas Lagoon starting the week of Sept. 29, or the following week.  The harvesting will be to vegetation in preparation for the winter recreation season.

Volunteers to Raise Monarch Butterflies for Schools

.
Volunteers needed!

The monarch's numbers are in steep decline--we can't save them unless children know about their amazing metamorphosis and migrations!

So the Friends of Lake Wingra has a program to raise Monarch Butterflies for schools.

We've worked out a method, delivering 13 large caterpillars and chrysalises to Thoreau Elementary School.  With your help, we can supply more classes.

The second grade classes at Thoreau School were very excited.  Rapt with attention, the kids asked many smart questions.  Some of the kids are already experienced raising unusual pets--and a number of them begged me to give them monarch eggs.  One gave me a "thank you" hug when we were done.

Here's what's involved.  You can participate in the whole process, or just one of step.  We can train you.  Contact David Thompson at 233-9589.

Thoreau butterfly garden is attracting lots of pollinators

.
Today, the butterfly garden at Thoreau School was glorious.  The New England aster was in bloom with deep purple flowers that attracted nine or more species of insects.  The various bees, flies, and butterflies are feeding on nectar--and in the process pollinating the flowers.  A good deal for both.

The Thoreau Butterfly Garden was funded with a grant from The Friends of Lake Wingra.

The garden is a wonderful example of biodiversity.  One seldom sees such variety of colorful insects in one spot. You don't have to be concerned with tedious identification.  It's a pleasure to just observe, note the differences, and see how many different kinds you can find.

Let's take a look at what's there.

This hoverfly is nearly as big as a bumble bee.  You can tell it's a fly because it has only two pairs of wings, and huge eyes.  With black and yellow stripes, it gains protection from predators by looking like a bee.  Tentative identification: Flower Fly

Reconstruction scheduled for Monroe Street

..
The City has rescheduled reconstruction of Monroe St, to 2015.  Budgetary issues caused the delays.

There have been two sessions in which the public was invited to make suggestions for the project.  During the first, I suggested that the City adopt a design goal of not exporting stormwater to the lake for storms up to a selected intensity (let's say a two-year storm).

Such a goal would be easier to achieve if the City (or FoLLW) also adopted a program to encourage better handling of stormwater on private properties nearby.  For example, if more people disconnected their downspouts from their driveways (and the street), then the Monroe Street project wouldn't need to handle as much stormwater.

During the second pubic meeting about Monroe Street, in which City staff summarized input from the first meeting, there was no mention either of adopting a stormwater export standard, or of a program to encourage better infiltration on private property.

The "Green Street" pilot program dropped

A green street seeks to reduce stormwater runoff and associated pollutants, bring natural elements into streets, and improve access for pedestrians and bicycles.  A new green street program can create a standard for a neighborhood, generating pride.  Since Monroe street is a gateway neighborhood to the City for a large number of commuters and visitors, it sets the tone for all of Madison.

Monarch butterfly lays eggs in new butterfly garden

.
The new butterfly garden at Thoreau School, funded by Friends of Lake Wingra, is a success!

On August 18, I dropped by the garden and was delighted to see a colorful monarch waltzing around the garden--surprised since I have seen so few this summer.

Insects as pets

.
Not many people keep insects as pets nowadays, although the ancient Chinese kept crickets in little cages, to hear them sing.

Over the years, I've kept about 20 different species as pets, but George the monarch caterpillar was my first insect.

When I was a college student, I had a pet tarantula.  (Spiders are much different from insects.)  While I was driving on a back road at Stanford, I saw him crossing the pavement and took him home to my dorm.

Having no other handy cage, I put him in my empty waste basket.  There he sat for several months.  When I entered the room, he'd feel my vibrations and scuttle around the bottom of the basket.  I imagined it was a dance of joy at my homecoming, like Fido's greeting.   Perhaps not.

I'd toss in a few flies or a big bug every day or so, which he happily ate.  But after several months, he died--probably from starvation or dehydration.  His communication skills were poor, so he couldn't communicate what he needed (as if I was listening).

Pros and cons of insect pets

Caterpillars are very different from kitties and doggies.

Advantages
  • No neurotic behaviors or misbehavior.  Never chew on your shoes.
  • Don't run off (at least not fast)
  • Food is inexpensive.
  • No need for vaccinations or license.
  • Expands your mind.  Teaches about metamorphosis.
  • Insect metamorphosis puts human puberty in perspective.
  • You get three pets for the price of one.  Caterpillar, chrysalis, and butterfly.

Monarch caterpillar behavior

Monarchs are growing steadily

Most people have heard of the miracle of metamorphosis, when a caterpillar transforms itself into a moth or butterfly.  But not many have watched the day-to-day behavior of a caterpillar.

Perhaps that's because it's about as exciting as watching molasses flow.

But wait!  Caterpillars really do have behavior!  They just have a clock that runs more slowly.  Finding out what they do is a challenge.

Bacteria--from above the clouds to miles below your feet

.
In the last 20 years, our knowledge of bacteria has undergone a revolution.  We now know that bacteria can live inside solid rock.  Bacteria live and reproduce high in the clouds--where they help form rain as water condenses upon their bodies.

The first hints came in the 1960s, when scientists in the Antarctic found algae living and growing inside the pores of rocks.  The climate near the south pole was harsh--but the microscopic plants found conditions INSIDE rocks to be warmer and wetter than outside.

Since then, bacteria have been found growing in the pores of solid rock several kilometers below the surface.  How they got there is a mystery.  Perhaps these are the descendants of bacteria present in the sediments from which the rocks formed millions of years ago.

These buried bacteria are able to grow without sunlight by harvesting the energy found in chemical compounds, such as rust or sulfur.  Some even live off the natural radioactivity in rocks.  They persist like Rip Van Winkle in a state of suspended animation--metabolizing just enough to repair damage to their DNA--individual cells perhaps living for eons.
