Mountain Bikers & Trail Runners: Slow Down for Snakes!

Here in Colorado, at least along the Front Range, we enjoy a variety of "wilderness" recreational opportunities from hiking to rock climbing. Sometimes differing modes of trail enjoyment come into conflict, and sometimes the wildlife suffers even worse consequences. Here I will relate why people traveling over trails at high speed (mountain bikers and trail runners specifically) need to understand their potential impacts on reptiles in particular.

I have been fortunate to encounter at least four species of snakes along popular trails in various parks and open spaces. Snakes make use of patches of earth unobstructed by vegetation in order to bask, warming their bodies for active hunting later, to help digest a meal, or otherwise regulate their metabolism. Trails are ideal for this purpose and it is not uncommon to find serpents stretched across the full width of a trail.

Obviously, venomous snakes such as the Prairie Rattlesnake also pose a threat to people using trails. Trail runners must be mindful of the potential to encounter rattlesnakes, especially in early morning or early evening hours, and on overcast days. I personally recall one afternoon when a trail runner passed me, and I almost tripped over a Prairie Rattlesnake shortly thereafter. I suspect the runner never saw it.

When traversing terrain at a high rate of speed, it is essentially impossible to notice a snake or other small organism on the trail. If it is noticed it may be mistaken for a branch or other object. Snakes are generally well-camouflaged and overlooked even by those seeking to find them.

Besides the fact that a snake cannot move rapidly enough to avoid an oncoming bicycle tire, or running shoe, it is usually not programmed to do so behaviorally. A snake's primary defense against a perceived threat is to rely on camouflage and stillness in hopes the predator or danger does not detect it. So, snakes are, figuratively if not literally, "sitting ducks" when it comes to oblivious mountain bikers and trail runners.

There is evidence that other types of small animals also suffer from collisions or other encounters with mountain bikers and trail runners. While my chief personal interest is in insects and spiders, and I find a great deal of carnage related to even regular bicyclists, most invertebrate species have robust, widespread populations that can withstand even heavy mortality. Not so with many reptiles, small mammals, ground-nesting birds, and other organisms. Remember that all animals are subject to many non-human mortality factors as well: Predators, parasites, disease, and infertility for example.

What can you do to avoid conflict and still enjoy yourself? Consider recreating at a time of day when reptiles are not normally active. Yes, that means late morning through afternoon during the warmer months. Winter riding means little or no conflict with wildlife. Slow down, especially in open habitats such as prairies, meadows, and glades, south- or east-facing hillsides, and along rock outcrops. Ride only on trails designated for mountain biking (but you do that already, I'm sure). If there is a park headquarters, visitors center, or nature center, consult with personnel there to find out which trails are best, and whether there is frequent wildlife activity along them.

Thank you for reconsidering your riding and running habits and becoming more "wildlife-friendly" to other creatures. Those of us who share the trails but move at a slower pace and enjoy our encounters with animals will be grateful for your thoughtfulness.

The Red Bull Rampage

My wife likes to turn on the Today show in the morning while we have breakfast. The trivia that passes for news is usually only mildly annoying, but one story today set me on fire. Reporter Jenna Wolfe covered the “Red Bull Rampage,” an extreme mountain biking competition in what I suspect used to be a pristine Utah landscape. I am not sure which turns my stomach more: the event itself, or the fact that NBC is glorifying this destructive spectacle.

Here in Colorado Springs I see firsthand the deep gullies and gashes eroded by mountain bikes. While most of the riders are courteous and careful when it comes to sharing trails with pedestrian hikers, the damage done to the soil is appalling. I will still grant them the right to ride on trails in an urban or suburban setting, but to carry out their freewheeling in wilderness (officially designated or not)? No way. I have another solution, which I will discuss later.

Back in the day we used to call extreme sports participants “daredevils.” We could still call them that today, but the emphasis should be on “devil.” We could also call it “wreckreation,” because that is what is happening to the environment in the wake of tire treads, litter, and other negative impacts. Erosion, siltation of streams and other water courses, and destruction of wildlife habitat is what you get out of repeated abuse by trail bikes, motorized or pedaled.

In any event, you are defacing something beautiful. There is no other word to describe this competition except “vandalism.”

Then there is the scenic aspect. What was once something sculpted completely by wind, water, and geologic upheaval is now scarred permanently in the name of “sport.” I find it ironic that this is billed as a dangerous sport, yet people with pick-axes and shovels carve out “routes” for the bikers to use in the Red Bull Rampage. In any event, you are defacing something beautiful. There is no other word to describe this competition except “vandalism.” You might as well ride over the paintings in the Louvre. It is just as disrespectful an act, if not moreso, to scribble permanent tracks over a landscape eons in the making.

What would I do instead? I would hold events like this in landscapes already compromised by human enterprise. Abandoned open pit mines come to mind. I can think of one in Bisbee, Arizona that would be ideal. Think about all the upsides to this. You can make a course as difficult as you like. You can have emergency medical personnel and transportation standing close by in the event of a horrible accident. Your closer proximity to a city or town would generate revenue for that municipality. Abandoned mines, old landfills, and other parcels of land already scarred by human activity abound on this planet. There is absolutely no need to exploit pristine wilderness.

I plan to write to NBC News to protest both the story on this morning’s Today show and their plan to air the Red Bull Rampage event in its ugly entirety next month. This is not sport, and we have to stop glorifying it as such. Push for alternative locations for such things. Take a piece of land that is beyond repair and hold such competitions there. Everyone can be happy if we put our minds to it. We conquered Nature long ago. What we are doing now is tantamount to torture. There are international agreements against torturing human beings. Maybe we need that kind of accord to protect Mother Nature, too.
