“Treasures of OZ” celebrates nature in Ozaukee County

Queen's Lady's Slippers, Cedarburg Bog State Natural Area
One of the highlights on a daylong tour of Ozaukee County parks was this patch of Queen’s Lady’s Slipper blossoms. The rare orchid, also known as “Showy” Lady’s Slipper for obvious reasons, has disappeared from much of its former range because its preferred soggy habitat has also largely disappeared. But there it was, almost within arm’s length, next to the narrow boardwalk that allowed me to walk into Cedarburg Bog—prime orchid habitat.

Like the flower, the opportunity to enter the boardwalk at the Cedarburg Bog State Natural Area between Saukville and West Bend is also rare. Operated for research and educational purposes as a U.W.—Milwaukee Field Station, access is usually restricted. But as one of the “Treasures’ of OZ” the bog is part of an annual celebration of parks, preserves and natural areas in Ozaukee County.

I was delighted. Although I’d been to the research station before I’d never been out into the actual bog. The boardwalk led through thickets and across a large pond covered in lily pads fringed with cattails. The trail continued on over a couple of islands of solid ground before the boardwalk resumed and plunged into the heart of the bog. Several species of native Wisconsin orchids more diminutive than the Lady’s Slippers appeared here and there.

Pitcher Plant, Cedarburg Bog State Natural Area
Most exotic to me, however, were the pitcher plants, which grew out of the waterlogged earth in abundance. The carnivorous plants were in bloom, which was new to me. The blossoms, past prime, had lost their drooping petals, leaving behind a flower head that resembled an alien satellite dish. Brightly colored blossoms of many species speckled a landscape dominated by tangled knots of stunted tamaracks. The boardwalk and the special event made it possible to visit an otherwise impenetrable wilderness.

More than a clever marketing phrase, “Treasures of OZ” was billed as an Eco-tour and Science Expo. The “expo” parts of the tour featured a wide variety of interesting activities involving wildlife, science displays, food vendors, music and a raffle. But clearly the real treasures of OZ are the natural havens themselves.

In addition to Cedarburg Bog this year’s tour included two county parks, a popular state park, and two preserves managed by the Ozaukee Washington Land Trust. Being familiar with them already, I skipped Harrington Beach State Park and Spirit Lake Nature Preserve. (Coincidentally, I included Spirit Lake in my recent story about five “hidden gems” of Milwaukee area parks.)

Ehlers County Park
Ehlers County Park is a narrow strip of riparian land along the Milwaukee River two miles north of Saukville on Highway W. It boasts a prairie awash in wildflowers as well as 2,200 feet of shoreline. Scientists with the Ozaukee County Fish Passage Program and Milwaukee Riverkeeper were on hand for the tour to demonstrate the diversity of fish and macro-invertebrates in the Milwaukee River.

Kelly Ostrenga, with Milwaukee Riverkeeper, holds a rusty crayfish, an example of a macro-invertebrate.

Tendick Nature County Park
As I would learn belatedly, Tendick Nature County Park has two segments. Since I foolishly neglected to consult either the Treasures of OZ website or a map, I turned in at the first segment I reached as I drove north on Highway O from Saukville.

Surprised to find no one there, I nevertheless enjoyed the prairie and magnificent clouds before heading back south without discovering the second, larger and more popular segment. Sometimes you find what you’re looking for…

Snapping Turtle, Forest Beach Migratory Preserve

My final stop of the day was Forest Beach Migratory Preserve, the epicenter of the Eco-tour and Science Expo. Randy Hetzel, a genial and loquacious naturalist with a traveling wildlife collection, thrilled a rapt crowd with a menagerie that included snakes, frogs and turtles. Having experienced their ferocity in the wild, I was particularly amazed to see how casually he and his teenage daughter handled a huge snapping turtle.

Buckeye Butterfly, Forest Beach Migratory Preserve
Forest Beach is home to the Western Great Lakes Bird and Bat Observatory. Its mission is to study bird and bat populations and promote their conservation throughout the Western Great Lakes region. After stopping indoors briefly to inspect the exhibits, I headed out to explore the trails. I didn’t notice many birds—migration season has passed—and it was too early in the day for bats. What I did see in astonishing abundance were a wide variety of butterflies.

Forest Beach Migratory Preserve
I had heard that the 116-acre preserve had once been a golf course. As I wandered through the wildflowers with butterflies fluttering all around me it was hard to imagine fairways and greens. The thunderstorms that had been predicted never materialized but a turbulent sky rose over a landscape that remained serene and entrancing. We humans have little in common with orchids but like those delicate and sensitive flowers we require a certain measure of nature in our lives. I know I do. And I feel fortunate to live near enough to enjoy these treasured places.
