Default Trail-Building: Habitat Destruction by a Different Name

Trail-Building: Habitat Destruction by a Different Name
Michael J. Vandeman, Ph.D.
September 2, 2017

"Impacts on and along trails result from the trampling of hikers and pack stock and the effects of trail construction and maintenance. … These impacts include the loss of vegetation and shifts in plant-species composition, exposure of bare mineral soil, soil compaction, and changes in microhabitats, including changes in draining and erosion. Where trail construction is carefully planned, most of these changes are of little concern; although pronounced. Most changes are localized and deliberate." Dawson and Hendee, 2009, pp. 423-4

Scientists are generally honest, in what they say – but not in what they choose to study. Despite a diligent search in one of the world's best libraries (the University of California, Berkeley), I wasn't able to find a single book or article on the harm done by trail-building. I notice that whenever I see a picture of a trail, I think "Oh, a trail – so what?" It takes an effort of will to think about the wildlife habitat that was destroyed in order to build the trail. And the habitat destruction isn't restricted to the trail bed. As Ed Grumbine pointed out in Ghost Bears, a grizzly can hear a human from a mile away, and smell one from five miles away.. And grizzlies are probably not unique in that. In other words, animals within five miles of a trail are inhibited from full use of their habitat. That is habitat destruction! If there were no trails, we would be confronted by our own destructiveness every time we entered a park. It is only because the habitat has already been destroyed for us, that we can pretend that we are doing no harm.

So why do we build trails? It doesn't take much experimenting with cross-country travel to see that it is extremely difficult. There are many kinds of hazards – biological (e.g. poison oak, poison sumac, poisonous snakes, etc.) and physical (e.g. blackberry thorns, cliffs, rivers, volcanos, etc.). It is extremely difficult to find a passable-, much less an efficient, route. It would be very difficult to communicate our location to emergency personnel, without trails. So it is unlikely that we will eliminate trails in the near future, except from areas designated off-limits to humans.

That leaves only one option compatible with wildlife conservation: minimizing the construction, extent, and use of trails. For example, banning the use of off-road vehicles, such as bicycles, skateboards, and motorcycles would greatly reduce the use of the trails, the distance that people travel, and the harm done to the soil and the small animals and plants found on, under, or near the trails. Mountain bikers complain about being thereby "denied access", but of course they can still walk. They just can't easily travel as far as they can on a bike. On public land, especially, all trail construction should be thoroughly studied, and should be built only when officially authorized by the land manager, and only by thoroughly educated, authorized builders.

By far the greatest threat to wildlife habitat in so-called "protected" areas would appear to be mountain biking. Motorized vehicles are generally not allowed in natural areas. The most destructive use of trails is mountain biking. Knobby tires are perfectly designed to rip up the soil. Mountain bikers, with rare honesty, call their riding "shredding". They also have a much greater range than hikers, and probably also equestrians. They also frequently ride illegally – where bicycles are not allowed.

All of this is well known. But what isn't so well known or understood is the mountain bikers' drive to build ever more trails. All park users seem to have a need for a certain amount of stimulation. A hiker or equestrian can satisfy that need on a relatively short trail, because they experience it fully, through all of their senses. They can stop instantly, and turn 360 degrees, seeing, hearing, smelling, touching, or tasting anything they choose. Mountain bikers, on the other hand, tend to ride fast, often as fast as they can, seeking what they call an "adrenaline rush". But even when riding slowly, the very nature of a bicycle requires one to focus almost 100% of his or her attention on the trail immediately in front of their front tire, or they will crash. The consequence is that they have to travel several times as far as a hiker, to have the same quantity of experience. And after riding the same trail a few times, they get bored with it and want to ride a new trail. And when they've ridden all their local trails, they begin demanding more trails to be built. Or, if their demands aren't met, they begin secretly building illegal trails, or building illegal "trail features" (jumps, berms, log bridges, teeter-totters, etc.). The rain-forests of North Vancouver are the iconic example (which destruction continues to this day), but it has been emulated by mountain bikers all over the world.

If this were a matter of a few sites or a few trails, it wouldn't be too significant. But it's not restricted to one area. Mountain bikers, apparently ignorant of conservation biology, have destroyed thousands of square miles of wildlife habitat, and show no signs of slowing down or recognizing the harm that they are doing. IMBA (the International Mountain Bicycling Association) has been promoting mountain biking tourism, claiming that mountain biking brings economic benefits to communities that embrace it, of course ignoring the economic value of the intact ecosystems they are destroying. The mountain biking infrastructure is called "epic trails", "ride centers", "bike parks", etc. They bait their demands with offers of volunteer trail-building and trail maintenance. (But, of course, their vision of a good trail (lots of humps, twists, and turns) is quite different from what the other trail users want.)

In the San Francisco Bay Area, projects were created to build two huge trails – the Bay Trail and Ridge Trail – each several hundred miles long, circling the bay near the water and along the ridgetops. The community enthusiastically voted for these projects, waxing poetic about all the "new opportunities" to "connect to nature". Actually, no new habitat was created, and the trail construction (which still continues) destroyed an enormous amount of habitat. Nevertheless, I never heard anyone complain about this. People seem to think that trails somehow thread their way through the wilderness harmlessly, without touching it.

Haven't we already destroyed far too much wildlife habitat? Isn't it time we started telling the truth about trails and our construction and use of them?

Here are a few examples of the destructiveness of trail construction and use (for an online copy of this paper, where you can click on the links and won't have to type them, see https://mjvande.info/scb9.htm):

IMBA promotes trail-building:
"Saturday is National Public Lands Day
Get connected with your local IMBA chapter or club to see if it is hosting a volunteer trail day this Saturday. Trails don't build themselves...show some love for the places you love to ride!
Dig In Applications Open Through October 6
IMBA is currently accepting applications for its new Dig In Campaign - a grant program that directly supports local IMBA chhapters [sic] with actionable trail projects. The project list will be published in early October so stay tuned to see what's happening near you."

IMBA: "IMBA is currently accepting applications for its new Dig In Campaign, a grant program that directly supports local IMBA chapters with actionable trail projects. We are committed to growing access for mountain bikers and increasing the pace of new builds in the U.S." "It takes a village: that statement of wisdom is particularly true in the mountain bike community, where volunteers, experts and funders must come together to make great places to ride happen. In Wausau, WI, the Central Wisconsin Offroad Cycling Coalition (CWOCC), an IMBA chapter, recently completed a multi-year project that resulted in a pumptrack, four bike-optimized downhill trails of varying difficulty and a beginner-friendly loop, all designed by IMBA Trail Solutions.."

Don't forget this one. This is what "rock armored" mountain bike trails turn into during heavy rains:
https://youtu.be/pOXYaYFfLyo
Because of all the damage done to our mountain slopes from too much trail building, they are building debris flow basins in our creeks, here -- but the authorities won't stop the mountain biking... It is costing us millions of dollars....

Here is more from British Columbia:

Delta, BC...
https://youtu.be/7q67O7r60fY (Illegal trail damage to riparian area)
This trail build was legitimate, but shows the damage done by too many people trail building, and pulling huge roots out, in a stupid kind of challenge race to see which team can build the most trail in the shortest time. Pure mayhem at work here (all through pristine area of forest, destroying the ground cover, and digging borrow pits to collect dirt and rocks to pack on the trails):
https://youtu.be/muicHp5kaKs (at the .24 mark, you can see a guy just tear out a large tree root...) "When Arc'teryx challenged MEC to a trail building competition, we jumped at the chance to get dirty... plus we couldn't resist a little friendly competition. So on November 17, dozens of MEC staff and supporters met up with the NSMBA to dig, grub and mine for gold on the North Shore. Our goal was to build more trail than Arc'teryx over a few hours."

Mountain bikers are also degrading forests and thereby contributing to global warming:

The damage mountain bikers do on Fromme Mtn. Seems one builder, MW, who left the NSMBA hasn't gone away (still digging on the North Shore) -- and the NSMBA continues to give a thumbs up to this sort of digging and building:
http://www.pictame.com/media/1472817...3069_435668765

More trenches dug in the name of "sustainable" mountain biking...:
http://www.pictame.com/media/1553816...3049_435668765

and this is what they dug up the forest to build (video of the jump structure in action):
http://www.pictame.com/media/1555623...6041_435668765

How many buckets of gold dirt [mineral soil] and borrow pit digging was required to pack all that dirt on the eroded mtb trail on Mt. Fromme?:

This is what the NSMBA bragged about last year... How much more this year? For your trail building files/paper to show how devastating this all is:

http://www.euanforresterphotography....-trail-fairies (click on each photo with cursor to see the story behind the illegal trail building..... some of it at night time, hiding under darkness.) This is now celebrated and applauded.... wrong became a right, overnight... This is how mountain bikers won CMHC... This is the sordid history of mountain biking on our North Shore...

So much digging for dirt to pour over their ever eroding and compacted trails. The riding style seen in the last part of this video is the reason why the trails become that way, eroded and compacted. Anyone who tries to paint this MTB sport as benign as hiking, etc. needs to watch this until their eyes pop out!:

Illegal mountain biking on Mount Royal is damaging its ecosystem, experts say. Repeatedly crossing the mountain's soil loosens tree roots, affects Laurentian flora: http://www.cbc.ca/news/canada/montre...king-1.4675779
