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.
