Hidden dangers lurking in the forest

When hiking, always look up

- By John Mccaslin Rappahanno­ck News staff

When hiking in Shenandoah National Park, including along the Appalachia­n Trail, one doesn’t often lump falling trees into the category of potential hazards. We keep an eye out for ticks, bears and venomous snakes, we take precaution­s against heat and hypothermi­a, and we are careful when crossing streams and navigating steep slopes.

But as Rappahanno­ck property owners know all too well of late, falling trees or branches — as tragically seen last month along the AT in nearby Clarke County — are not only commonplac­e but potentiall­y deadly, particular­ly given our extreme weather.

Like people, all trees are in varying degrees of health. The tree on August 21 that had a large branch break off and land on top of 72-yearold hiker Tae Sung Kim, killing the Northern Virginia man, was rotting.

Most trees at first glance will give some sign of deteriorat­ion — from cracks and cavities to decay and discolorat­ion — so it’s always smart when pausing along wooded trails to check your immediate surroundin­gs.

And be sure to look up. Broken limbs often lurk in trees, caught up in other branches and in many cases just teetering there.

But it’s what we don’t see that is most dangerous.

Tree roots — 90 percent of which are in the upper 1824 inches of soil — weaken during heavy rains, and with the severely saturated ground of late in Rappahanno­ck a toppling tree can prove deadly. Particular­ly when high winds slice through the mountains, as this county experience­d earlier this year when thousands of otherwise healthy trees came crashing down. The taller the tree the more susceptibl­e to winds.

Keep in mind that deciduous trees — oaks, maples and elms — have a greater lateral root spread, offering more support, whereas the roots of conifers — pines, cedars and firs — are more compact and fibrous.

Finally, exposed roots around the base of a tree are a sign of danger, adding to the hiking hazards.
