For thousands of years, people have lived here.  Native people thrived in this area because the land provided everything they needed.  Natural resources were abundant, and they knew how to use them without destroying the land.  I often wish that I could know what they know, or knew, about nature.  I know that it is a far deeper knowledge than I have.  Fortunately there are wonderful Indigenous authors out there, like Robin Wall Kimmerer, a professor from New York State who learned not only from her culture, but also from the University of Wisconsin.  She talks about a relationship with plants that I appreciate, but can only dream about.  I admire such people immensely.
 
Back to this area.  As I said the land provided what people needed, and for thousands of years people took everything they needed, given by the land, without degrading nature.  A number of resources made that possible in this area- abundant game is often the first thing we think of, but microbes and plants are where everything starts.  There are certainly accounts of abundant wildlife in colonists journals- deer, bear, wolves, all around Two Rivers.  Many fish, including whitefish were present in the rivers, maple trees were present in the forests along the shores, and in the rivers themselves no doubt there was wild rice.  Maples and wild rice were critical resources, as were birch trees, sometimes referred by native people as the “tree of life” because their bark especially had so many uses.  Mushrooms were edible and medicinal.  Everything had a use.
 
Wild rice is a grass that was once abundant in this area.  At one time there were wild rice beds continuously from Green Bay to Escanaba, for example, and it was certainly present in the estuaries of rivers adjoining our lakes.  Over the years, those extensive beds disappeared due to human activity- logging, shoreline development, waves from boat traffic, and invasive plants and animals, and soil and fertilizer causing algae growth in the water.  Wild rice prefers fairly clear, soft bottom conditions without too much disturbance.  Wild rice is very important to the Ojibwe people, who came from the east seeking manoomin or “food that grows on water”.  Wild rice was harvested extensively in late summer for food- an intensive process of paddling or poling canoes out to the rice beds, bending the stalks over the boat with one stick, and tapping the stalks with another, causing rice to fall into the canoe.  It seems simple, but it is laborious, and takes a lot of practice.  It is not too efficient- people have developed much more effective ways of harvesting rice mechanically.  However, the traditional way of harvest allows some of the rice to fall back into the water to reseed the beds, ensuring that wild rice crops will be sustained in the future.  People were aware of this, and knew that they were helping to feed future generations.  Too much efficiency is not always good.
 
After harvest, the rice was parched over a fire, trampled to remove husks, and winnowed by throwing it into the air, allowing husks to blow away.  It was then stored and used as food throughout the winter, to supplement wild game and fish.  The quality and abundance of the harvest determined how difficult winter would be for the people.  Today, wild rice is still a sacred and important food to the Ojibwe, and is also sold by some to supplement their income.  Fortunately, some of that rice is harvested for seed, some of which was purchased for restoration purposes last year.
 
Working with Dr. Titus Seilheimer of UW SeaGrant, we are trying to restore wild rice to the marsh at Woodland Dunes, now primarily dominated by cattails.  The high water the last few years has drowned some of the cattails, leaving areas of shallow water in the marsh adjacent to the nature center on the West Twin River.  Last fall Titus and I took wild rice seed he obtained from Minnesota, and brought it out by canoe to the river in November, on one of the last warm days.  The rice was soaked in water, and was simply tossed out over a variety of sites with shallow water over several acres.  We only had about 20 pounds of rice I believe, so we spread it on several small areas.  The rice then needs months of cold under water before germination is possible.
 
This spring, Dr. Seilheimer visited the West Twin with restoration folks from UW- Green Bay, who are working on an extensive project on the Bay itself.  Wonderfully, they found that some of the rice we planted had indeed germinated and had grown to the surface.  At this stage the plants lay flat at the surface of the water, what is called the floating stage of development.  I visited the site this week by boat, and I found plants that had now emerged from the water and had grown 8 inches or so above the surface.  It was a sight I had only dreamed of seeing in my lifetime.  This fall, we will do more planting- it often takes five years or so to really get beds established.  The rice will not be harvested by humans- what the ducks don’t eat will fall to the bottom to re-seed next year’s crop and supplement our work.
 
Wild rice is not only an important wildlife food source, it is important culturally to this area.  Having the opportunity to bring it back to our property is a gift that we great appreciate.  We hope that someday there will be acres of this important plant on our property, and along the nearby Twins.

photo of spittlebug in spittle and snailNow that we’re fully into summer, I urge you to slow down with nature and observe it at a “Sunday Driver’s” pace, or in natural terms, a snail’s pace.

Instead of hurrying to list all the bird species you can find, go for a walk or hike with the idea of listening for food-begging sounds from nestlings, or observe which plants are flowering right now. Then take a closer look and notice how busy they are with pollinators.

While doing that, see if you notice bubbles on the leaves or stems. That’s the product of the spittlebug. Spittlebugs are so cool and so underrated. This tiny insect sucks up watery sap from the plant, lots and lots of sap, so it creates lots of urine – like 150 to 280 times its body mass every day. (Wow!) The urine comes out as the bubbly foam. The bubbles form a safe cocoon for the insect to grow and protect it from predators. Hang out and watch the bubbles for a while, you might see the tiny nymph moving around inside.

Take advantage of the warm night air and be a kid again – go look for lightning bugs! These bioluminescent wonders are a free visual concert, but like so many other insects they’re facing serious threats. Next to habitat loss, light pollution is their big enemy. Lightning bugs depend on their ability to light up and be seen for courtship and attracting a mate, but too much artificial light is interfering with this. Find a nice lot away from city lights that has nice green vegetation, they like moisture. Enjoy this precious moment in awe. Savor what you find.

Observe moths pollinating at night. Nocturnal flowers with pale or white flowers and a strong fragrance attract moths. Just follow your nose to your next dusk-discovery.

Challenge yourself to identify five evening sounds and once you get them, go for five more.

Since we’re observing at a snail’s pace, why not look for snails? Did you know that Wisconsin has 100 land snail species? You can find them on all kinds of surfaces because they know how to get around, it just takes a while. Secrete slime. Crawl. Secrete slime. Crawl. You get the picture.  

Snail slime, a natural product to be sure, but it’s no longer for locomotion only. Some cosmetic companies are now using it as an exfoliant that removes dead skin cells and stimulates cell renewal. Cool nature nerd fact – snail slime’s exfoliating properties are attributed to the natural collagen, elastin and glycolic acid found in it.

So, let’s not “busy” our summer away. Let’s not be in a rush to list birds, but forget to admire and appreciate them. Slow down. Relax on your back porch and just observe what nature is doing around you. In summary, see the snail, be the snail.

They aren’t normally considered caped heroes, but our pollinators are just that. Heroes. This week is National Pollinator Week and we’re happy to be celebrating our tiny-sized eco-celebrities.

Pollinators, unfortunately, are decreasing in population due to pollution, misuse of chemicals, disease and changing climate patterns. Declines are also happening due to reasons that we fully don’t understand yet, which in itself is cause for great concern. Thankfully, awareness is on the increase and Woodland Dunes is partnering with many like-minded organizations to help spread the word: Manitowoc County Soil and Water Conservation Department, Lakeshore Natural Resource Partnership, US Fish and Wildlife, NRCS, Van der Brohe Arboretum, Harmony Cafe, and a participating family farm. All of us got together this week to offer a pollinator tour to those interested in learning what they can do on a large or small scale to make a difference.

Why are we celebrating insects, bats and hummingbirds – all varieties of pollinators? Because pollination is crucial to our survival. Even refrigerator magnets remind us that one third of the food we are about to eat is pollinated by bees. As much as we may like a juicy steak, a healthy diet for humans still depends on a balance of vegetables, nuts and fruits – compliments of our pollinators. And money talks. Pollination is also crucial to our economy – pollinators produce more than $40 billion dollars worth of products in the US annually. Pollinator plants are also good at producing the oxygen we need to breathe and sequestering carbon dioxide.

But let’s go back to that survival thing. Today it seems that so many things are crucial to our survival – less oil dependence, less violence, and increased healthcare. I don’t think any of these things are disputable, but at the very basic level, we’ve got to give our pollinators a real hard look. And more attention. And for our own sake, help them out. Here are just a few compelling reasons from the USDA:

  • Some crops, including blueberries and cherries, are 90 percent dependent on honey bee pollination.
  • 90 percent of the nation’s apple crop is pollinated by bees.
  • Growers and consumers realize increased yields and higher quality crops from a healthy pollinator population, native or managed.
  • Worldwide, approximately 1,000 plants grown for food, beverages, fibers, spices, and medicines need to be pollinated by animals in order to produce the goods on which we depend.

So what can you do?

Consider putting a butterfly garden in your yard or creating a “clump” space where you can plant some native flowers to attract pollinators. Be mindful of soil characteristics, sunlight, and other factors when selecting your plants.

  • Provide a variety of flower colors and shapes to attract different pollinators.
  • Choose plants that flower at different times of the year to provide nectar and pollen sources throughout the growing season.
  • Avoid the use of pesticides. Practice Integrated Pest Management (IPM) to reduce damage to your plants and to protect pollinators by using less chemicals.
  • Pollinators, need water too. You can provide water for pollinators with a shallow dish, bowl, or birdbath with half-submerged stones for perches.
  • In the fall, leave your dried plant “skeletons” and do not clean them out in the spring until there is a week straight of 50 degree weather to give hibernating pollinators the best chance of survival.

Together, we can make a difference and honor our pollinators in true fashion – bringing them back from a troubled state and celebrating our quality of life because of them.

Many visitors to Woodland Dunes walk on the Cattail Trail boardwalk north of the nature center, and explore several different wetland habitats and eventually reach the marsh along the West Twin River. Because one can access these interesting and usually inaccessible habitats, Cattail is our most popular trail. The boardwalk meanders through shrub swamp, an alder thicket, sedge meadow, and cattail marsh. Each habitat has distinct plants and animals, and the boardwalk allows one to explore very wet areas but yet have dry feet. Some of the interesting animals encountered are mink, snapping turtles, yellow and common yellowthroat warblers, swamp sparrows, marsh wrens, ospreys and bald eagles, sora and Virginia rails, ducks, hundreds of red-winged blackbirds, and many more species.
 
What is striking now is that the alder thicket has obviously taken a beating in recent years.  Speckled alder is an interesting tree, often found in the north but able to live here due to the cooling effect of Lake Michigan. Alders are not large trees, more like large shrubs. They grow in wet soils in clumps. They have many small openings called lenticels on their trunks, which allow the transfer of oxygen from the air to their roots, helping them cope with water in the soil. Their roots support nodules of bacteria which store nitrogen from air, providing nutrition to the alders and surrounding plants.
 
Because alders grow in wet soils, those soils are often soft and don’t support the trees well when the trunks become large.  During high winds, alders often tip over.  Also, alders like soils that are wet but not too wet. As a result of storms the last two summers, and recent high lake water levels which influence the lower West Twin, many of the alders have been either blown over or have died back from excessive wetness. The result is a landscape which has many dead, fallen small trees- a tangle of wood on the ground or water. Visitors are often alarmed at the mess now where a pleasant thicket of small trees had been.
 
Of course, what is happening is natural, not due to disease or predation. Wind and soils were not favorable to the alders recently, but now the water is starting to recede a bit.  The cycle of renewal is beginning- young alder shoots are sprouting from the trunks of their fallen parents. In a few years there will be a new alder thicket. In the meantime, the tangle of fallen wood provides wonderful habitat for many birds.  Woodpeckers seek insects in the dead trunks; afterward chickadees excavate nest holes there.  Rails forage for food beneath the fallen wood, songbirds seek insects near the water under the cover of the branches, and life goes on.
 
Wetlands are dynamic habitats, undergoing many changes as the plants adapt to changing conditions over time.  Fallen, dead trees in this case does not indicate a problem, just a transition.  It will be interesting to see what happens as time goes on, but for now if you visit and see dead alders, know that it’s not a problem, just change in the process.

With the onslaught of the emerald ash borer in full force now, we are seeing its effects more and more all around us.  Some areas appear to be devastated, with many dead and dying ash trees failing to leaf out.  This can appear to be a very depressing landscape to view, but we should keep in mind that forest ecosystems are very complicated, and all is not lost.

 
Woodland Dunes has many areas which are dominated by ash trees- areas which have not yet been discovered by other water-loving tree species.  Ash are aggressive at reproduction, and quickly fill in areas devoid of other trees.  After our area was logged, ash repopulated large areas of wetlands and provided a valuable service to people and the ecosystem.  However, their density and success turns out to hasten their downfall, as this has made it easier for the Asian insect to spread, along with our propensity for moving wood from one place to another.  That some areas are so dominated by one species is a bit artificial- in undisturbed systems many species find homes, and usually no one disease or consumer affects them all.  Older forests are like a reserve of many species which can help to re-populate devastated areas.
 
In response, people years ago began harvesting ash trees while their wood was of high quality, knowing the trees would not survive.  There is no treatment that can be applied to a forest.  Municipalities rightly are removing trees from parks, knowing they will die, become unsightly, and become a danger to park users.  Fortunately many are quickly replanting, hopefully with native species of trees.  In some cases, trees can be saved by using systemic insecticides, but that requires annual effort and expense.  In my yard I’ve chosen one ash tree planted by my grandfather to try and save, but I will have to treat it forever.  Cities are doing that on a very select basis also, as are other homeowners.
 
At the same time we need to think ahead.  There is no downside to planting trees.  Just remember that native trees benefit wildlife far more than non-natives.  And we need diversity- after the elms died in a similar way, we probably over-planted ash trees, because they were not known to have many disease problems.  We didn’t anticipate our once again bringing in a problem from overseas, as we did with chestnuts, elms, and others.  Currently hemlocks, beech, and others are experiencing problems caused by introduced pests and diseases- another reason to be more careful in importing any living things from elsewhere.
 
But in addition to planting replacement trees there are existing helpful trees waiting to grow.  In the swampy areas at Woodland Dunes, speckled alder are already present under the taller ash trees.  As they get more light when ash die off, I would anticipate they will prosper and help shade out some invasive plants like reed-canary grass.  Red maples are present around the edges and in some of the shallower swales, and they will also prosper with more light.  In addition to those, we are planting other water-loving natives such as silver maples, swamp white oak, tamarack, and hackberry.  But perhaps more important than planting, it is important to look for other native seedlings already present on your property and give them a hand.  Chickenwire caging to protect them from deer in the first few years is really important.  At home I have an area with seedling oaks, basswood, and spruce.  The spruce will be fine, but deer chew down the oaks and basswood, which really benefit from caging and grow quickly with protection.
 
Diversifying our properties with a variety of native tree species will benefit every species in the forest.  In time, predators like woodpeckers, nuthatches, and wasps will consume some of the ash borers, which will run out of ash trees on which to reproduce.  A few ash trees will always survive, but they will never dominate like they have been, and over many years they will learn to resist the ash borers, as they do the more than a dozen native borers in Wisconsin.  Our whole forest ecosystem is being reorganized thanks to our ignorance, but that’s what forests do.  We need to carefully observe, and assist where it’s appropriate, which I think is the best way to honor the forest itself.
