Natural Connections

As I climbed back into my car with a camera full of more lovely wildflower photos, I smiled at my good luck. Here in Wisconsin and Minnesota, we have quite a variety of habitats and soil types in a relatively small area. I can explore rich soils and maple forests filled with trilliums, wild oats, and large-flowered bellwort one day, then delight in the bedrock home of bird's eye primrose (and a not-yet-booming mystery plant) the next. And now here I was enjoying prairie flowers in a barrens!  What do we have to thank for these riches? Why the glaciers, of course!

Bohemian waxwings are known for their ability to find a tree full of berries in the middle of nowhere, descend on it en masse, strip every edible fruit from the twigs, and then disappear to their next meal. That's exactly what they did as I watched.

Heading north on Highway 63, the beautiful scenery never fails to keep me entertained as I drive through the picturesque nature of the Northwoods. While my thoughts wandered, a large dark spot high in a distant tree caught my eye. At first, I thought it might be a squirrel drey–a large nest of twigs and leaves built high in a tree. But as I got closer, I realized that it was a porcupine! Once my excitement calmed down, curiosity began to take its place. I began to wonder why exactly this porcupine was high up in the tree on this late fall morning. The answer may lie within the feeding strategies of the North American porcupine.

The arching stems, decorative berries, and warmly hued, persistent fall foliage of barberry, plus the complete lack of deer browse on their twigs, are why they were brought to the U.S. as an ornamental plant in 1875. That was fine, until in the 1980s they started to spread out and displace native plants. Now Japanese barberry is considered invasive in 17 states, including Wisconsin, Minnesota, and Iowa.  A barberry thicket also provides a safe, fox-resistant haven for mice, and a shady, humid home for ticks. Deer ticks feed on mice, who are reservoirs for Lyme disease. 

Beside the trail stood a spreading shrub with a few rays of sunlight illuminating tiny yellow flowers that looked just like sunbursts themselves. Witch-hazel! The flower-dappled shrub twinkled like a reminder of spring. While they do bloom near Halloween, witch-hazel's name is probably a misspelling of old English words wicke or wych that meant "lively" and "to bend." They refer to the use of a forked branch of witch-hazel as a dowsing rod, which purportedly would bend downward to point out a good location to dig a well. In a bit of reverse-dowsing, rain showers helped me see the leaf, and sun rays helped me see the witch-hazel. On that fall day, I found a deep well of beauty. 

"Turn here, they're heading north!" I directed my fiancé as we navigated the gravel roads of Crex Meadows Wildlife Area near Grantsburg, WI. We'd spotted a line of sandhill cranes flying through the sunset sky, and were following them toward what we hoped would be a spectacular evening of birdwatching. 

The air shimmered as I walked through the forest, the heavy mists encompassing me in a damp blanket. As my shoes trod on soggy leaves, I took in the quiet serenity of the forest. Many of the trees had begun their annual changing of the colors, painting the canopy in shades of yellow, orange, red and green. Their discarded leaves were already beginning to dot the forest floor in late September. But fallen leaves weren't the only contributors of color on the ground–the fall mushrooms were popping in the Northwoods. 

At first, a flutter at the edge of my vision made me think that an autumn leaf had somehow managed to fall half a mile to the middle of the lake. A closer look revealed the dark purple wings of a mourning cloak butterfly. In late September?  Weeks later, a flutter at the edge of my vision caught my attention just in time to watch an autumn leaf come to rest on the ground. Small quaking aspen leaves carpeted the trail in a mosaic of yellow and green. They were evidence of yet another way that a Lepidopteran (butterflies and moths) survives the winter. Colorful leaves and colorful wings flutter on fall breezes, all getting ready for winter. 

Last week I wrote about acorns clattering across my roof. As it turns out, nuts are raining down on many of your roofs, too! Commiserating over the loud, foot-rolling acorns makes me feel like part of an extended community. Are the oaks part of a similar community? And why are they suddenly attacking us with acorns! Oaks are mast species, which means that all the trees in an area will produce a bumper crop of acorns at the same time, but only every two to five years. From mice to owls to chatting neighbors, oaks, and the mystery of their mast years, are at the center of our Northwoods community.

The pontoon bobbed in the water as I stepped onto the deck, clutching binoculars and trying to contain my excitement. Since moving to the Northwoods in the middle of winter, I had been waiting for the chance to see a loon, and my chance finally arrived in late May. The sunlight danced across the water as our boat left the dock, and we began our search. It wasn't long before we spotted the silhouette of a loon off in the distance, and headed for a closer look. 

Crack! Rumble, rumble, rumble. Crack! The sound of hard objects pelting my metal roof shot through my open bedroom window, rousing me from the last wisps of sleep. Then silence. I braced myself as a soft hush of wind drew closer. Crack! The wind triggered a new spatter of noises. The house was under attack—by acorns.  Two large red oak trees reach the edges of their canopies out over the roof of my house. Each fall, they create a racket as acorns drop on the metal roof, tumble down the steep slope, and launch out over the driveway. Some years are worse than others, since oaks are mast trees who will produce a bumper crop in one year, then spend subsequent years rebuilding their stores of nutrients and not producing as many acorns. This is clearly a mast year. 

Shades of Rot and Life (This essay is a chapter from Emily's third book, Natural Connections3: A Web Endlessly Woven, which will arrive in November 2025!) In the dim light, under the thick, hardwood canopy of the forest, death was everywhere.  Of course, life was everywhere too.

We'd only been watching for a few minutes when suddenly one of the loons took off running and flapping down the bay toward the main lake. Huge, webbed feet splashed at the surface. As soon as the first loon rose above the water, the remaining loon followed in a flurry of flapping wings and feet. What had just happened? The group looked around at each other in amazement, feeling lucky to have witnessed this fascinating bit of loon behavior.

Although the temperature plummeted and rain ran off our jackets, our excitement and determination could not be dampened. Rubber boots tromped over soggy leaf litter, and hands grasped at every fallen log, flipping them over as we searched the forest. The Wild Wonders campers and I were on a mission, seeking out an animal who thrives in rainy conditions–the salamander.

I was just about ready to round up the group and move on from the old quarry when someone exclaimed over a pretty white flower among the weeds. Five luminous petals, each with translucent lines arcing gracefully toward the nectar reservoir in the center, provided the backdrop for a ring of delicate eyelashes tipped with glossy yellow spheres. I could barely believe my eyes! I first met bog star, or marsh grass-of-Parnassus, during my summer in Alaska while assisting with a snowshoe hare study in the Brooks Range. This little beauty captured my imagination immediately.

This summer, as a Summer Naturalist Intern at the Museum, she taught our Junior Naturalist programs and showed a real talent for finding and appreciating the oddest parts of nature.  I spotted the male first. He was sitting on the highest point of the mushroom shelf like he was the king of the hill. Then I spotted his mate, who to my surprise, looked like she was sitting up. I knelt down and cocked my head to the side to get a better look. For beetles who usually crawl on all six legs, this was an unusual position. Was she laying eggs?

I was reveling in this fact as I took my evening meander through the large trunks of towering trees. To my left, I spotted a shelf fungus clinging to the bark of a half-decayed paper birch stump. Creeping closer to investigate, I squealed with delight. There they were! Two forked fungus beetles were nestled in the corner of their polypore home.

Guest writer Kylie Tatarka is about to start her senior year as an environmental science major at Rochester Institute of Technology. This summer, as a Summer Naturalist Intern at the Museum, she taught our Junior Naturalist programs and spearheaded the creation of the online  "Becoming the Northwoods" exhibit.  Seeing the aspen-covered ground reminded me of a tree that is more common in my home state of New York, the eastern cottonwood tree, which is a relative of the aspen with similar cotton-tufted seeds. I grew an affection for these trees while leading a seed dispersal hike. With the kids, we discovered examples of seeds that are dispersed by wind, water, animals, gravity, and bursting. Now I'm always on the lookout for plants with interesting methods of seed dispersal.

The Boundary Waters is beautiful, but that's only part of it. What really keeps people coming back, I believe, is the way this place helps us to challenge ourselves. When you cut out the excess, the superfluous, and the mess, and fit everything necessary for a week or two of life into a single, green pack, life becomes simple. There is an incredible sense of freedom in this knowledge of self-sufficiency. This freedom feels all the more sweet when it comes with manageable challenges and a means to test our mettle.

Upon spotting the green dragonfly resting close enough for me to capture, I knew I had to try. With my kayak nestled into the grassy bank of the Namekagon River, I snapped a few photos of my target and began to reach my hand out slowly. But when my fingers gently grasped the dragonfly, I was horrified to find that it was squishy rather than the typical hard feeling of an exoskeleton. My hand shot back to my side in an instant, repulsed. My first thought was that the dragonfly was dead and waterlogged.
