Not So Scary
Friday, July 9th, 2010Many of the small members of our ecosystem– the minor players who inhabit our fields and forests– have developed outsized reputations that are not always deserved. We’ve been taught to cringe at the mere sound of their names, but this is not always necessary. Let’s take a minute to place some of these scary characters in perspective.
Poison Ivy:
Poison ivy can cause cases of contact dermatitis ranging from mild to severe in about 70 percent of the population. But for the other thirty percent, the plant is a simple and honest citizen of the underbrush, meaning no harm and occupying a necessary niche in our complex biosphere.
For those who are susceptible, poison ivy is easily identifiable by its characteristic three leaves extending from a single midpoint. Imagine three football shaped leaves about the size of a bay leaf (on the youngest and smallest plants) to person’s hand (on the largest.) Poison ivy looses its leaves in the winter, but oil can still reside in its dormant vines which are easily recognized by their fur. Avoid the three leaves and steer clear of the soft furry vine climbing that fence or tree and you should avoid a few days of uncomfortable itching.
Ticks:
Like poison ivy, ticks are simple citizens just trying to make a living. Big dog ticks are fairly easy to spot—at their smallest, they’re about the size of this capital letter “O”. When you see a dog tick making its way across the sleeve of your shirt, take a look at it. What is its stripe pattern? Lady ticks wear necklaces—a curved stripe from one side of the ticks head to the other. And gentlemen ticks wear suspenders—two straight parallel lines down the back. If the tick has made its way to bare skin and taken a bite, remove it carefully with tweezers, doing your best to remove both the head and body intact.
Tiny deer ticks are the more sinister characters that can occasionally carry Lyme’s disease. Not all ticks are infected with the disease, and not every infected tick will successfully pass the disease on to a host.* Deer ticks can be harder to find, so the best method of dealing with them is prevention. In high deer tick areas, wear long sleeves and pants, preferably in light colors.
Snakes:
Only four primary species of snakes in America are poisonous, and only two of those (the rattlesnake and the copperhead) live in Pennsylvania.* Like most animals, snakes are far more frightened of you than you are of them. Snake avoidance is most important in rocky areas where snakes may be sleeping or sunning themselves and may not have time to get out of the way of your feet. This also applies to hands when you are climbing a rocky surface– Take care when choosing hand and footholds. If you see a snake of any kind on the trail, observe it with respect and leave it in peace.
Respecting these and all forest dwellers can increase our appreciation of them, and by extension, our appreciation of the remaining wild areas around us. Protect yourself from the harm they cause, but don’t let them keep you hiding indoors. After all, the woods belong to all of us!
*The American Lyme Disease Foundation reports the following:
Less than 5% of adult ticks south of Maryland are infected with B. burgdorferi, while up to 50% are infected in hyperendemic areas (areas with a high tick infection rate) of the northeast. The tick infection rate in Pacific coastal states is between 2% and 4%.
* The Pennsylvania Fish and Boat Commission reports the following:
The three venomous species of snakes in Pennsylvania are the northern copperhead, eastern massasauga rattlesnake, and timber rattlesnake. Reports of venomous snakebites in Pennsylvania are rare.
