A Forest is More Than Trees

We won’t forget August 10, 2020.  On that summer day, Cedar Rapids was hit with 140 miles an hour winds that tore off roofs, felled signs, and toppled at least 65% of the City’s trees. The damage was awesome.

We lost 47 of our 53 big trees at Winding Pathways and spent the next two months cutting up a twisted jumble of trunks and branches. We bucked up what we could for firewood and made huge brush piles on the north end of our property for wildlife habitat. We used chain saws for cutting but muscle power to haul brush and wood.

Nearly all woodland owners suffered similar damage, and most of them immediately began clearing away broken and downed trees. Some used heavy equipment to haul off debris, leaving bare soil in the woods, a perfect seedbed for weeds.

Resetting the Forest

The derecho reset Iowa’s woods. Prior to settlement most of the state was prairie with woodlands typically lining streams and rivers. Frequent wildfires raced through grasslands and never hesitated when they encountered woods. This created a savanna ecotype characterized by scattered fire-resistant big trees, mostly oaks, walnuts, and hickories, with a stunningly diverse array of wildflowers carpeting the ground.

Savanna was an “open” forest. It lacked a shrub understory, and because trees didn’t create a closed leafy canopy sunlight dappled the ground. Perhaps no forest is as beautiful or endangered as savanna.

Iowa’s settlers quickly suppressed fire. Gradually trees closed the canopy, keeping the ground in shade most of the day. Many savanna flowers need some sunlight and declined as a shrub layer, often of exotic invasive woody plants, thrived. Many woods that owners considered healthy were actually degraded by years of fire protection.

The derecho changed it within under an hour. Many trees fell to the ground, but others survived.   Woodlands will now have sunlight reach the ground, stimulating both invasive species and long-suppressed native wildflowers.

Planning and Planting

The woods on the east side of our house created nearly a complete canopy, but suddenly they fell. After we cleared away the debris, we did these things:

  • Planted a few white and bur oaks in the fall. We’ll plant a few more next spring.  All are protected from deer browsing with a stout ring of wire mesh.
  • Purchased a diverse mix of savanna wildflowers and a few kinds of grass from Pheasants Forever. Mid-November brought two inches of new snow, and we hustled out to broadcast the seeds on it. It’s called frost planting and works well.
  • Discovered some tiny oaks, hackberries, and walnuts amid fallen trees. We marked them and know they’ll grow rapidly next year.

Recovery will be slow. Newly planted trees grow slowly their first few years and savanna and prairie seeds take a few years to establish. We don’t expect to see much change in 2021 but our “new” savanna will eventually be gorgeous and look much like it would have in the early 1800s.

Sources

We bought our prairie seed from www.pheasantsforever.org.  Our fall-planted trees were ordered from the National Arbor Day Foundation www.arborday.org.  Spring planting will be of trees we bought from Chief River Nursery www.chief rivernursery.com.

We’ll follow up our planting with occasional prescribed burns to retard invasive plants and invigorate natives.

What Happens to a Photovoltaics System When the Grid Goes Down?

Four years ago, we installed a net-metered photovoltaic system on our barn roof. Photovoltaics, or simply PV, is a term that means “light electricity” or solar energy.

Solar panels

On sunny days solar powers our energy needs.

We appreciate our PV system. On sunny days, when our system produces more electricity than we use, it runs our meter backward as power flows out into the energy grid. At night and on cloudy days, when we’re using more power than we’re producing, we draw electricity in from Alliant Energy, our utility.  At the end of each month, we pay the “net” so it’s called a Net-Metered System. This eliminates the need to have storage batteries. We’ve had a monthly bill as low as $5!

But what happens when the grid goes down? It did on August 10, 2020, when a derecho roared through Iowa with 140 mile an hour winds. Hundreds of miles of wires were torn down as trees crashed into them. We joined thousands of other homes without power.

Important items to have along.

Solar chargers help keep people connected when the power goes out.

So, did our PV system power our lights, computers, and television? Nope. We used candles and lanterns when it got dark and couldn’t power our computer, television, or any other electric appliance for about two weeks.

Net-metered systems, like ours, have an automatic switch built into them so they don’t export electricity back to the grid when it’s down. It’s a safety mechanism designed to prevent a utility employee working to restore power from getting a shock. Our system produced electricity during the blackout, but it just dissipated. As soon as our power was restored the PV system again sent power outward.

 

An Important PV Safety Tip

Our PV system survived the wind intact but others were ripped from roofs and tumbled to the ground. A PV panel laying on the ground upright makes electricity.  Grabbing wires or the panel can give someone a tremendous shock. If a PV panel is on the ground stay away……or cover it with a tarp to darken it so it doesn’t produce electricity. It’s safest to wait until after dark to flip it.

 

Crinoids. Forsaken by the Iowa Legislature?

Sometimes blessings spring from catastrophes.  That happened years ago when a massive flood inundated Iowa’s Coralville Reservoir. Water overtopped the dam built to control downstream flooding. As the raging river gushed over the emergency overflow spillway it ripped soil from bedrock before invading downstream homes and businesses with gooey muck. When the flood subsided visitors discovered an amazing array of fossils in newly exposed limestone. Many were crinoids. 

Just what the heck are crinoids?

You won’t find a living crinoid in Iowa today because our ocean abandoned the Hawkeye state years ago, but about 600 species still live in faraway seas. Fossils teach us that millions once thrived here.

Iowa was once a vast ocean where calcium wafted down through the water column as it formed limestone. Dig down nearly anywhere in Iowa and sooner or later you’ll hit limestone. Chances are that the rock contains crinoid fossils, the remains of the vanished Iowa fauna. In some parts of Iowa, especially Southeast Iowa, crinoid pieces make up a significant portion of the bedrock.

In what is now Iowa, those crinoids lived some 310 to 485 million years ago, give or take a few million years. They looked more like branching flowers than crawling, swimming, or flying animals we’re familiar with.  Although they appear plantlike crinoids are animals.

Why doesn’t Iowa Have a State Fossil?

Iowa can’t claim them exclusively, as crinoids are found in limestone worldwide.   Missouri honored this humble animal by designating it their state fossil. The Cedar Valley Rocks and Mineral Society has worked for years encouraging the Iowa legislature to follow the example of our neighboring state and name our common crinoid Iowa’s state fossil.

In this day and age when public opinion and political parties are leagues apart, one would think to designate these ancient Iowans as our state fossil would be nonpartisan and popular. So far, no dice from the legislature. Iowa lacks a state fossil.

To learn more about crinoids and other fascinating rocks, minerals, and fossils check out the Rock and Mineral Society’s Website.  Everyone’s welcome to attend their meetings and lend a voice encouraging the state to honor Iowa’s crinoids.

Winter Reading with Winding Pathways Gazette Features

Winding Pathways invites readers to enjoy past features in the Cedar Rapids Gazette.

The Bear Tooth Theatrepub. Great eateries. Iditarod Ceremonial Start. XC ski races. Campbell Creek Science Center.  And, perhaps most wonderful of all – no skeeters or bears!

Indiana Dunes National Park.  A great stop while speeding along I-80 is the Indiana Dunes National Park.  A cooperative venture among city, county, state and federal government, this necklace of preserved areas rings the southern end of Lake Michigan. Soft sand beaches to explore, dunes several hundred feet high to scale, charming villages, bicycle trails to follow, and varied places to rest your head at night. This new national park can fulfill any family’s vacation dreams.

America’s Magnificent Mounds line the Mississippi River and many other waterways in North America.  While most mounds have been lost to “development” many remain. And, travelers can learn so much about ancient cultures and appreciate why preserving these mounds is important.

Are You a Weather Spotter?

Guest Blog by Jacki Hull of Bedford, Virginia

Written about April 19 and 20 storms

“Well, two ugly storms in one week is enough for us for a while. Today has been full of dark clouds, winds, rain. Then as we
were sitting on the porch for a quiet read of the daily paper, I could see rapidly rotating clouds, some heavy rain and heard
a roar of the wind.

Tornado Safety

“I told Peter (spouse) that we needed to get inside. As we moved ourselves to the living room, I prayed that it would not come
our way. (In 2002 a tornado did set down on Kelso Mill Road not far from us.) Well, the funnel stayed about a mile west of
us, but what a mess. Fortunately, no one was hurt, but our friends were really shaken. Buildings down along with trees.
It was duly noted by me how fierce the wind was because the bark was stripped off branches and 200-year-old trees twisted
and shorn of their branches. Electricity was out because poles were down and the lines were broken.

“I called the electric company to report no electricity on Solaridge. The gentleman asked me my location which I told him. Then he
told me there had been a tornado, the crews were on their way and it would be a few hours before everything was back online.

“Because (at the time) Channel 13 didn’t seem to know for sure if it was a tornado, I called the National Weather Bureau to let them know what I had seen. I love the weather and clouds and have been a weather spotter for years since taking a weather class at CVCC. Anyway, Ben at NWB told me the investigators would be coming to Kelso Mill Road and Sharp Mountain Road to check the damage and make an assessment tomorrow which would be on the news Saturday night. I asked him to call me and let us know what their findings are.

“Well, that’s all the excitement for today. Like I said two ugly storms in one week is enough all ready.”

Polar Vortex Labyrinth Lessons

My daily labyrinth walk on Wednesday, January 30, 2019, in the middle of the Polar Vortex coughed up several lessons.

In spite of the bitterly cold morning, the snowshoes strap that slipped off and glasses that fogged up, it was a great walk!  Nothing I want to repeat, though.

Here are some lessons:

(Think ahead.) Just like a little kid is reminded, it is better to use the bathroom before donning the multiple layers of clothes.

(Before starting out, make sure your equipment is ready and working. Think ahead number two.) Pulling the snowshoes down from the hooks in the unheated garage, I realized the straps were frozen. “Oh well, I can make this work.” Ha!  At -25 degrees? Not. Gloves were too bulky to fix on the straps, so I took them off. Within seconds my fingers were numb.

(Be ready for consequences. Think ahead number three.) Not only were my fingers numb but also because I hurried putting the snowshoes on, one strap slipped off partway through the walk causing me to stumble. Additionally, when I wrapped my scarf around my nose and breathed out, my glasses fogged up. Between the two, I pitched off the packed trail into the deep snow. I regained balance and came back on the path. It was kind of scary even though I knew my husband was monitoring my adventure from the house.

(Have a back-up plan. Think ahead number four.) Oh, I could have done the finger labyrinth, or “walked” the outdoor labyrinth from the upstairs window.  I also love a challenge. Yet, how much was just showing off for those who live in warmer climates and marvel at how the northerners survive?

(Turning back is OK!) A few times I thought about cutting off the path back to the beginning and just coming inside. That would have been OK.

(Persevering is also OK.) So, “keeping on keeping on” is valuable.  Just be aware and safe in our pursuits. When a situation is hard, ask, “Why?” And, then make decisions from there. Move into a growth attitude of “I can do this.”

(Be of Growth Mindset) Learn from missteps. Just like my shortcut crossing on the industrial pipe above the dam and jagged rocks as a little kid, this adventure was good to do.  Maybe not one to repeat. Get back on the path.

(Be grateful.) Always a valuable lesson. From small to large gratitudes express them many times each day.  This changes everything.
