New Oak Signals Hope

May’s first few weeks are the most delightful time to be outdoors.  Warm days combine with the delicious scent of spring.   It’s the peak time for birds that wintered far to the south to either settle in to nest or briefly rest and eat before winging further north. Their songs fill the air.

Early May awakens plants, and in early May Rich discovered a treasure.  It was an oak sprout that seemed to have “hope” written all over its new soft green leaves.

The seedling radiated hope.

Winding Pathways adjoins Faulkes Heritage Woods, an area of sloping land bordered by homes on the south and Indian Creek to the north.   Last August 10th a derecho bearing 140 miles an hour wind tore through Iowa.  Neither Winding Pathways nor Faulkes Woods was spared. Trees, many of them enormous, either snapped off or uprooted, leaving a scene many called “devastation.”

At first, that seemed like an apt description, and the woods looked ravaged all winter.   Rebirth comes with spring. While sitting on a fallen log Rich looked down to see a tiny white oak sprout.  It just seemed to say, “Hi, here I am ready to grow.”

Oaks thrive on sunshine, and with big trees now felled on the ground, light floods the soil to energize the leaves of the baby oak and other seedlings. Gradually the old tree will decompose.  Its wood will add nutrients to the soil to be appreciated by the youngsters.

Nature has amazing resiliency.  One just needs to look to see it.

 

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.

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.

Why Do Trees Fall on Calm Days?

Early one May afternoon we arrived home, glanced into the woods past our property, and were astonished to see an enormous red oak on the ground. The tree looked healthy, solid, and unlikely to topple, but it fell on a clear calm day. On its way down the old veteran broke two younger trees growing nearby.

A week or so later we woke to an enormous crash. It was pitch dark so we were only able to search around with a flashlight to learn that nothing had hit our house. The next morning, we discovered a giant elm prostate on the ground about 150 feet from our bedroom on a neighbor’s property.  Like the oak, it fell when it was calm. Unlike the oak, the elm had been dead for years and many mushrooms were growing from its trunk.

We enjoy a huge diversity of birds and other wildlife in our yard, in part because we adjoin Faulkes Heritage Woods, a 110 wild forest protected by a conservation easement. The Woods have not been logged for over a century, so many enormous oaks, hickories, and maples live there. Many are dead or in decline, but that’s great for wildlife.

Dead trees provide food and nesting sites

Of all landscape features few are as valuable to as many wildlife species as an old dead tree. Nearly as soon as a tree dies insects, bacteria, and fungus begin the long process of recycling wood and bark back into humus. Woodpeckers drill into dead trees to extract tasty insects and carve out nesting cavities. Often their old cavities are used by chickadees, wrens, and many other cavity nesters. Dead trees are favored perching sites for raptors, perhaps because they are leafless, so the sharp-eyed birds can spot prey on the ground.

We let dead trees stand on our property, as long as they are far enough away from the house so they can’t cause damage or injure someone when they crash down.

Are Dead Trees Dangerous

We’ve been in the right place at just the right time to see big trees fall. Usually, there’s a crack or two before a giant tree crashes down with lightning speed. If someone were underneath it then it would be hard to run fast enough to escape injury.

The odds of a person being hit by a falling tree while walking along a trail are infinitesimally small. It almost never happens. Most injuries and fatalities occur when people camp, picnic, or sit under a tree. The risk comes because they are under the tree for hours while sleeping or in a position where they can’t run and escape quickly.

Tent away from trees

Look up when placing your tent near trees.

Before setting up a tent always look up and never pitch it under a weak or dead tree that could fall in the night.  

 

How to Tell If A Tree Is Likely to Fall

Rotted wood

It’s a wonder this tree stood as long as it did.

Determining if a tree is likely to fall isn’t always easy. Sometimes seemingly healthy strong trees fall over, but often one gives notice that it is in decline and weakening. Here are visible signs that a tree is vulnerable to falling:

  • It’s dead. No leaves. Branches occasionally dropping off. Bark sheathing off.
  • It’s alive but increasingly branches are dying and are bare of leaves.
  • Mushrooms are growing from the wood.
  • Little piles of sawdust at the base show that insects or woodpeckers have been at work.
  • It’s old. As trees age, they stiffen and eventually, their wood weakens. Young healthy smaller trees are more flexible and bend back and forth in heavy wind without damage.  Wind can crack the wood of old stiff trees.
  • All trees eventually fall down but some have notoriously weak wood that breaks easily. Silver maples, black locust, and Siberian Elms often shed big limbs or break during storms.

Should I Have A Tree Taken Down?

Losing a beautiful old tree is painful, but there is a time when the tree should be removed to prevent an injury, death, or damage. At Winding Pathways, we let even old weak trees stand as long as they are well away from the house or places where sit. But if the tree could fall and hit a parked car, house or barn we call a tree service and have it repurposed into firewood.

A Tale of Free Trees

This is a tale of free trees. Our friend, Marilynn Keller, learned how to plant the best tree species in her yard at no cost and with little work.

She simply didn’t mow a tiny area of lawn where she wanted a tree to grow. As if by magic, a White Oak, Sugar Maple, and Shagbark Hickory sprouted there this spring. Although the spot is too small for three trees Marilynn can simply decide which one she wants and mow the others off.

Small Oak

Likely a squirrel buried a nut that has sprouted.

Last fall an industrious squirrel gathered acorns and hickory nuts and buried them in her yard. The squirrel might have forgotten his hidden cache or perhaps died. Either way the unrecovered nuts sprouted.

Although squirrels often eat maple seeds, it’s most likely that Marilynn’s baby maple sprouted because a gust of wind pulled the ripe seed off a nearby tree and it helicoptered to her yard.

While Maples are usually easy to transplant, and are widely sold by nurseries, not so Hickories. Although any of the many Hickory species make outstanding shade trees, as soon as a nut sprouts it sends an enormous taproot deep into the ground. Moving a hickory is difficult and often unsuccessful. Commercial nurseries avoid them.

The same goes for white oaks, one of our favorite trees. It’s difficult to buy one to plant in the yard. Because they are slow growing and challenging to transplant, few nurseries bother with them.  Fortunately, they readily sprout on their own.

Maples along drive

In autumn Maples glow with color.

Anyone living where there are mature Hickory, Oak, or Maple trees nearby can use Marilynn’s tree planting method.  Simply don’t mow a patch of lawn where a tree is desired. Odds are one will appear on its own next spring. If more sprout than the spot can support just mow the others off and put wire screening around the new tree to protect it from hungry cottontails and deer.

If a tree sprouts in the wrong place it can be easily transplanted with just one shovel of dirt. Move it before the tiny tree has grown a long taproot.

How Do Squirrels Foil Hawks?

Much of my time and energy has been spent battling a 1-pound enemy – the gray squirrel.  I love feeding and watching birds, but with a neighborhood full of acorn-bearing oak trees I feel no guilt at all at not wanting to pay for bird food and letting the squirrels eat it.  Through trial and error, I have found how to place all our feeders so that they are always out of the reach of squirrels.  Almost always.  Every few months a new guy shows up; a determined daredevil squirrel who figures out how to slide 20 feet down the string holding a feeder to get to the mother lode.

When that happens, it’s time for an involuntary relocation.

This was the case on a frigid January morning here in Minneapolis.  My live trap was set and within minutes I heard it snap shut.  But what I then saw was a shock.  The squirrel was trapped all right, but sitting next to the trap was an immature red-tailed hawk!  She hopped onto the trap and all around it, trying to get at what she thought would be an easy breakfast.

Minutes later, she gave up and flew to a nearby perch to contemplate how she had been beaten by a 1-pound ball of gray fur.

I knew exactly how she felt.
