  1. Frequently Asked Questions about Mountain Biking Michael
    Vandeman, Ph.D. March 5, 2004

    1. Why do people mountain bike?
    a. They say that using a bike allows them to get much
    farther, in the same amount of time, than they can by
    walking. They also maintain constant pressure on land
    managers, to open more and more trails to bikes. Of
    course, all of these trails are already open to them, if
    they choose to walk. They also frequently claim that
    closing trails to bikes "excludes" them from the parks.
    This could only be true if they were unable to walk. Of
    course, they are able to walk. There's nothing inherently
    wrong with bicycling instead of walking; we all like to
    save energy, when it's appropriate. Use of a bicycle to
    replace automobile use is obviously beneficial. However,
    by the same token, replacing hiking with mountain biking
    is obviously not beneficial.
    b. They are interested in the quantity of nature they can
    see, rather than the quality of their experience. While
    riding a bike, especially over terrain as rough as a
    trail, one has to be constantly paying attention to not
    crashing. That make it almost impossible to notice much
    else. By contrast, a hiker feels the ground, hears all
    the sounds and smells all the odors of nature and can
    stop instantly, if he/she finds something interesting.
    The brain thrives on stimulation. A biker has to travel
    several times as far as a hiker, to get the same
    stimulation as a hiker. (And, by the same token,
    motorcyclists have to travel several times as far as a
    bicyclist, and an auto user several times as far as a
    motorcyclist, since they are enclosed in a metal box.)
    c. They are interested in thrills. Riding a bike on a trail,
    especially a trail containing many obstacles, or a trail
    one is not familiar with, is very challenging. (But if
    mountain biking is the high point of your week, as it
    seems to be for many mountain bikers, you must be leading
    a pretty dull life, off of the bike!)
    d. They are interested in building mountain biking skills
    and competing with other mountain bikers. The thrill of
    racing drives people to spend more money on their bike,
    and ride it harder and more often. Racing, up to and
    including the Olympics, drives a lot of mountain biking.
    Of course, it is also extremely harmful to the parks and
    natural areas that are used for practice! It is hard to
    think of any other (legal) use of public lands, other
    than hunting, that is as harmful as mountain biking.

    2. What is driving the sport of mountain biking? Besides
    the attraction for participants, manufacturers and
    retailers of mountain bikes and mountain biking
    accessories, as well as "adventure" travel guides, make
    a lot of money from promoting mountain biking. Even some
    auto manufacturers (e.g. Subaru) promote and sponsor
    mountain biking, and try to use its popularity to sell
    more cars. The tourism industry also promotes mountain
    biking, among other attractions.

    3. What harm does mountain biking do?
    a. Most obvious is the acceleration of erosion. Knobby tires
    rip into the soil, loosening it and allowing rain to wash
    it away. They also create V-shaped grooves that make
    walking difficult or even dangerous. The mechanical
    advantage given by the gears and ball bearings allow a
    mountain biker to travel several times as fast as a
    hiker. Given their increased weight (rider plus bike),
    this results in vastly increased momentum, and hence much
    greater horizontal (shearing) forces on the soil.
    (Witness the skid marks from stops, starts, and turns.)
    According to Newton, every action has an equal and
    opposite reaction. Mountain bikes were built much
    stronger than other bikes, so that they could withstand
    the greater forces they were subject to on rough trails.
    These same forces, therefore, are being applied to the
    trails! To give a definite number, the winner of a 20-
    mile race here in Briones Regional Park averaged 13 MPH
    (the speed limit is 15 MPH -- where were the park
    rangers?).
    b. A hiker must be very careful not to accidentally step on
    small animals and plants on the trail. For a mountain
    biker, it is almost impossible to avoid killing countless
    animals and plants on and under the trail. They have to
    pay attention to controlling the bike, and can't afford
    to look carefully at what is on the trail, especially
    when travelling fast. And even if they happen to see, for
    example, a snake, it is hard for them to stop in time to
    avoid killing it. A hiker, when crossing a creek, will
    try to avoid getting wet, by crossing on stepping stones
    or logs. Mountain bikers, on the other hand, simply ride
    right through the creek bed, crushing any animals or
    plants that happen to be there. Mountain biking magazines
    are full of photos of mountain bikers throwing up spray,
    as they barrel through creeks. Not only do bikes destroy
    animals and plants as they ride across streams, they ride
    through streams stirring up sediment. The sediment in the
    water interferes with the oxygen uptake by aquatic life,
    for example, killing fish- and frog eggs. Young fish,
    insects, amphibians, and aquatic microorganisms are
    extremely sensitive to sediment in water.
    c. Bikes also allow people to travel several times as far as
    a hiker. This translates into several times the impacts,
    both on the trail and on the wildlife (to say nothing of
    the other trail users). Existing parklands are already
    inadequate to protect the wildlife that live there. When
    they are crisscrossed by mountain bikers and legal or
    illegal trails, their habitat becomes even more
    inadequate. Mountain bikers frequently advertise rides of
    20-50 miles or more. Have you ever tried to walk that far
    in a day? In other words, allowing bikes in a park
    greatly increases human presence in that park and drives
    wildlife further from the resources that they need to
    survive, including water, food, and mates.
    d. Due to their width and speed, bikes can't safely pass
    each other on narrow trails. Therefore, policies that
    permit mountain biking also result in more habitat
    destruction, as trails are widened by bikers (or by
    hikers and equestrians jumping out of their way).
    e. Knobby mountain bike tires are ideal for carrying mud,
    and consequently exotic plants, fungi, and other
    organisms from place to place, resulting in the spread
    of exotic invasive species, such as weeds and Sudden
    Oak Death.
    f. Mountain biking is driving the very young and old off of
    the trails and hence out of the parks. Even able-bodied
    hikers and equestrians fear for their safety, and don't
    enjoy sharing the trails with bikes. (The mountain bikers
    claim that they are simply being selfish and "unwilling
    to share", but actually they have no problem sharing
    trails with mountain bikers; it is only their bikes that
    are a problem!)
    g. Mountain bikes, which are obviously built to go anywhere,
    teach children and anyone else who sees them that the
    rough treatment of nature is acceptable. This undoubtedly
    has a negative effect on people's treatment of nature.
    h. In order to mitigate bike-caused erosion, park managers
    have been resorting to extreme measures -- even in some
    cases putting a plastic matrix or other exotic material
    under the trail (e.g. in Pleasanton Ridge Regional
    Preserve, near Pleasanton, California)! It's hard to
    imagine that this will have a beneficial effect on the
    park and its wildlife….
    i. Allowing mountain bikes in a park greatly increases the
    damage to the trails, damage from "bootleg" (illegally
    created) trails, and the problems of conflicts between
    trail users, and hence the cost of maintaining the park.
    Considering how tight park budgets are, we can't afford
    the extra costs of policing, and repairing the damage
    from, mountain biking.

    4. Mountain bikers claim that their sport has no greater
    environmental impact than hiking. Is that true? If you
    read the "studies" that make that claim, you find that
    they don't really compare the impacts of hiking and
    mountain biking, but only the impacts per foot. If, for
    a moment, we assume that the studies are correct in
    their having equivalent impacts per foot, it would still
    follow that mountain biking has far greater impact per
    person, since mountain bikers typically travel so much
    farther than hikers. Besides overlooking distances
    travelled, those "studies" almost all ignore impacts on
    wildlife. And they don't study mountain biking under
    normal conditions -- only at a very slow speed.
    Actually, the comparison with hiking is irrelevant. It
    would only be relevant if we planned to allow only one
    of the two, and were considering which of the two is
    more harmful. In fact, no one is considering banning
    hiking. We are only considering adding mountain biking.
    Therefore, the only relevant question is, "Is mountain
    biking harmful"? (Of course, it is!) There is only one
    truly scientific study that I know of that compares the
    impacts of hiking and mountain biking. It found that
    mountain biking has a greater impact on elk than hiking
    (Wisdom, M. J., H. K. Preisler, N. J. Cimon, B. K.
    Johnson. 2004. Effects of Off-Road Recreation on Mule
    Deer and Elk. Transactions of the North American
    Wildlife and Natural Resource Conference 69: in press.
    Wisdom et al. 2).

    5. Where should mountain biking allowed? A couple of role
    models for wildlife protection are Yosemite National
    Park and East Bay Municipal Utility District (in
    Alameda and Contra Costa counties, California). They
    both restrict bicycles to paved roads, where they
    can't do much harm. Somehow bicyclists have managed to
    enjoy their sport for over a hundred years, without
    riding off-road.

    6. What should the policy be on trails? Closed to bikes,
    unless marked open. Signs that say "No Bikes" are
    quickly and repeatedly ripped out of the ground by
    mountain bikers.

    7. Isn't it discriminatory to allow hikers and equestrians
    on trails, but not mountain bikers? Mountain bikers love
    to say this, apparently because they think it will gain
    them some sympathy. The truth is that mountain bikers
    have exactly the same access to trails that everyone
    else has! It is only their bikes that are banned. If
    mountain bikers were really being discriminated against,
    they could easily go to court to gain access. However …
    they already have access to every trail in the world!

    8. Don't I have a right to mountain bike on all public
    lands? I am a taxpayer! The public has the right,
    through its elected representatives, to restrict how
    land is used. A federal court has already ruled that
    there is no right to mountain bike. It is a privilege,
    and any land manager who gives a good reason (such as
    safety or protecting the environment) can keep bikes off
    of trails (see
    home.pacbell.netmtb10.htm).

    9. Don't mountain bikers do some good things, like trail
    construction and trail maintenance? Trail construction
    destroys wildlife habitat both directly (by killing
    plants and animals) and indirectly (by reducing the size
    of the intervening "islands" of habitat). Moreover,
    mountain bikers favor trails that are "twisty"
    (sinuous), bumpy, and full of obstacles that provide
    thrills for mountain bikers. Such designs increase
    habitat destruction (by lengthening the trail) and make
    the trails less useful for hikers and equestrians. Trail
    maintenance sounds good, until you realize that it would
    hardly be necessary, if bikes weren't allowed there. The
    mountain bikers are the main reason why trail
    maintenance is necessary! Trails used only by hikers
    require hardly any maintenance. Therefore, admitting
    bicycles to a park greatly increases its cost of
    maintenance. Nothing is really "free", including trail
    construction and maintenance. (How does the saying go?
    "Beware of Trojans bearing gifts"?)

    10. But don't mountain bikers provide added safety, by being
    able to quickly summon help in the event of an
    emergency? I would rather trust in a cell phone, than a
    speeding mountain biker. Besides, natural areas are
    already one of the safest places you can be. In over 50
    years of hiking and backpacking, I have never witnessed
    any situation requiring emergency aid. Most people go to
    natural areas partly for solitude. If we wanted to be
    around large, fast-moving pieces of machinery, we would
    stay in the city!

    construction.)

  6. Preface: Having read many of Mr. Vandemans posts I think I can say with a degree of confidence that his posts are rhetorical in nature and not really intent on generating dialog. I also realize he's not likely interested in the opposing position. I further realize that I'm likely wasting key strokes at the present. With that said I have a few comments.

    Regarding the 'why'?
    Mr. Vandeman failed to mention the two main reasons why people mountainbike and why the sport is catching on, namely fun and great exercise?

    Mountain biking for many is an extremely enjoyable activity in which to partake. That Mr. Vandeman does not understand why it is such fun is irrelevant. I need not understand why people enjoy riding horses, but that does not mean that I do not understand that people do enjoy riding horses. My ignorance of their proclivities does not justify my demonization of their lifestyle.

    Further, mountainbiking is excellent exercise for both hand/foot & eye coordination and ones cardiovascular system. It is also less impacting on ones knees, hips, and feet than running. To provide example, if anecdotal, I cannot jog as my knee will ache if I do so more than once per week. I can however ride my bicycle (road or mountain) several times per week without experiencing any physical malady.

    Also one must consider that some people cannot be motivated to jog or run or even hike, being that personal tastes are widely varied in pursuits of exercise.

    Regarding the destruction...
    Sure, mountainbiking is more destructive than walking, but is less destructive than horseback riding. Having said that, if you are loath to accept mountainbiking due to its adverse effect on nature, why would you accept hiking as an alternative as hiking creates trails and destroys vegetation thus harming habitat?

    Truly if conservation is your priority then only the most acceptable policy would have to be avoidance of nature entirely.

    If you do not advocate utter human exclusion for nature then it all becomes various shades of gray as far as what is considered acceptable or sustainable conservation. Mr. Vandeman is in the extreme minority in his preview of what is acceptable, and as his letter suggest the majority opinion generally drives legislation, which is why mountainbiking is a sustained activity with a variety of locations in which to enjoy our sport.

    Closing commentary...

    Mr. Vandeman clearly has much time to post rhetorical diatribes on the injustices of mountainbiking to the internet all day. He clearly has the will to at least present an argument to support his position. What perplexes me is that with his purported education and self professed intelligence, why does he not see that a position of 'zero tolerance' is doomed to failure. He would probably do much more for the environment it he, rather than crusading to end the sport of mountainbiking, attempted to instruct us on environmental friendly policies to employ when mountain biking.

    He may also want to reconsider how he conveys his message. Except for those who are attending a church service, very few people are willing to consider a message when it is preached to them. Self righteousness never sold anything.

    there.

    Quoted message said:

    Mountain biking magazines are full of photos of mountain
    bikers throwing


    up

    Quoted message said:

    spray, as they barrel through creeks. Not only do bikes
    destroy animals


    and

    Quoted message said:

    plants as they ride across streams, they ride through
    streams stirring up sediment. The sediment in the water
    interferes with the oxygen uptake by


    aquatic

    Quoted message said:

    life, for example, killing fish- and frog eggs. Young
    fish, insects,


    amphibians,

    Quoted message said:

    and aquatic microorganisms are extremely sensitive to
    sediment in water.
    c. Bikes also allow people to travel several times as far
    as a hiker. This translates into several times the
    impacts, both on the trail and on the


    wildlife

    Quoted message said:

    (to say nothing of the other trail users). Existing
    parklands are already inadequate to protect the wildlife
    that live there. When they are


    crisscrossed

    Quoted message said:

    by mountain bikers and legal or illegal trails, their
    habitat becomes even


    more

    Quoted message said:

    inadequate. Mountain bikers frequently advertise rides of
    20-50 miles or


    more.

    Quoted message said:

    Have you ever tried to walk that far in a day? In other
    words, allowing


    bikes in

    Quoted message said:

    a park greatly increases human presence in that park and
    drives wildlife


    further

    Quoted message said:

    from the resources that they need to survive, including
    water, food, and


    mates.

    Quoted message said:

    d. Due to their width and speed, bikes can't safely pass
    each other on


    narrow

    Quoted message said:

    trails. Therefore, policies that permit mountain biking
    also result in


    more

    Quoted message said:

    habitat destruction, as trails are widened by bikers (or
    by hikers and equestrians jumping out of their way).
    e. Knobby mountain bike tires are ideal for carrying mud,
    and consequently exotic plants, fungi, and other
    organisms from place to place, resulting


    in the

    Quoted message said:

    spread of exotic invasive species, such as weeds and
    Sudden Oak Death.
    f. Mountain biking is driving the very young and old off
    of the trails and


    hence

    Quoted message said:

    out of the parks. Even able-bodied hikers and equestrians
    fear for their


    safety,

    Quoted message said:

    and don't enjoy sharing the trails with bikes. (The
    mountain bikers claim


    that

    Quoted message said:

    they are simply being selfish and "unwilling to share",
    but actually they


    have

    Quoted message said:

    no problem sharing trails with mountain bikers; it is only
    their bikes


    that are

    Quoted message said:

    a problem!)
    g. Mountain bikes, which are obviously built to go
    anywhere, teach


    children and

    Quoted message said:

    anyone else who sees them that the rough treatment of
    nature is


    acceptable. This

    Quoted message said:

    undoubtedly has a negative effect on people's treatment
    of nature.
    h. In order to mitigate bike-caused erosion, park managers
    have been


    resorting

    Quoted message said:

    to extreme measures -- even in some cases putting a
    plastic matrix or


    other

    Quoted message said:

    exotic material under the trail (e.g. in Pleasanton Ridge
    Regional


    Preserve,

    Quoted message said:

    near Pleasanton, California)! It's hard to imagine that
    this will have a beneficial effect on the park and its
    wildlife..
    i. Allowing mountain bikes in a park greatly increases the
    damage to the


    trails,

    Quoted message said:

    damage from "bootleg" (illegally created) trails, and the
    problems of


    conflicts

    Quoted message said:

    between trail users, and hence the cost of maintaining
    the park.


    Considering how

    Quoted message said:

    tight park budgets are, we can't afford the extra costs of
    policing, and repairing the damage from, mountain biking.

    4. Mountain bikers claim that their sport has no greater
    environmental


    impact

    Quoted message said:

    than hiking. Is that true? If you read the "studies" that
    make that claim,


    you

    Quoted message said:

    find that they don't really compare the impacts of hiking
    and mountain


    biking,

    Quoted message said:

    but only the impacts per foot. If, for a moment, we assume
    that the


    studies are

    Quoted message said:

    correct in their having equivalent impacts per foot, it
    would still follow


    that

    Quoted message said:

    mountain biking has far greater impact per person, since
    mountain bikers typically travel so much farther than
    hikers. Besides overlooking


    distances

    Quoted message said:

    travelled, those "studies" almost all ignore impacts on
    wildlife. And they


    don't

    Quoted message said:

    study mountain biking under normal conditions -- only at a
    very slow


    speed.

    Quoted message said:

    Actually, the comparison with hiking is irrelevant. It
    would only be


    relevant if

    Quoted message said:

    we planned to allow only one of the two, and were
    considering which of the


    two

    Quoted message said:

    is more harmful. In fact, no one is considering banning
    hiking. We are


    only

    Quoted message said:

    considering adding mountain biking. Therefore, the only
    relevant question


    is,

    Quoted message said:

    "Is mountain biking harmful"? (Of course, it is!) There is
    only one truly scientific study that I know of that
    compares the impacts of hiking and mountain biking. It
    found that mountain biking has a greater impact on elk


    than

    Quoted message said:

    hiking (Wisdom, M. J., H. K. Preisler, N. J. Cimon, B. K.
    Johnson. 2004.

    5. Where should mountain biking allowed? A couple of role
    models for


    wildlife

    Quoted message said:

    protection are Yosemite National Park and East Bay
    Municipal Utility


    District

    Quoted message said:

    (in Alameda and Contra Costa counties, California). They
    both restrict


    bicycles

    Quoted message said:

    to paved roads, where they can't do much harm. Somehow
    bicyclists have


    managed

    Quoted message said:

    to enjoy their sport for over a hundred years, without
    riding off-road.

    6. What should the policy be on trails? Closed to bikes,
    unless marked


    open.

    Quoted message said:

    Signs that say "No Bikes" are quickly and repeatedly
    ripped out of the


    ground by

    Quoted message said:

    mountain bikers.

    7. Isn't it discriminatory to allow hikers and
    equestrians on trails, but


    not

    Quoted message said:

    mountain bikers? Mountain bikers love to say this,
    apparently because they


    think

    Quoted message said:

    it will gain them some sympathy. The truth is that
    mountain bikers have


    exactly

    Quoted message said:

    the same access to trails that everyone else has! It is
    only their bikes


    that

    Quoted message said:

    are banned. If mountain bikers were really being
    discriminated against,


    they

    Quoted message said:

    could easily go to court to gain access. However . they
    already have


    access to

    Quoted message said:

    every trail in the world!

    8. Don't I have a right to mountain bike on all public
    lands? I am a


    taxpayer!

    Quoted message said:

    The public has the right, through its elected
    representatives, to restrict


    how

    Quoted message said:

    land is used. A federal court has already ruled that there
    is no right to mountain bike. It is a privilege, and any
    land manager who gives a good


    reason

    Quoted message said:

    (such as safety or protecting the environment) can keep
    bikes off of


    trails (see

    Quoted message said:

    home.pacbell.netmtb10.htm).

    9. Don't mountain bikers do some good things, like trail
    construction and


    trail

    Quoted message said:

    maintenance? Trail construction destroys wildlife habitat
    both directly


    (by

    Quoted message said:

    killing plants and animals) and indirectly (by reducing
    the size of the intervening "islands" of habitat).
    Moreover, mountain bikers favor trails


    that

    Quoted message said:

    are "twisty" (sinuous), bumpy, and full of obstacles that
    provide thrills


    for

    Quoted message said:

    mountain bikers. Such designs increase habitat destruction
    (by lengthening


    the

    Quoted message said:

    trail) and make the trails less useful for hikers and
    equestrians. Trail maintenance sounds good, until you
    realize that it would hardly be


    necessary, if

    Quoted message said:

    bikes weren't allowed there. The mountain bikers are the
    main reason why


    trail

    Quoted message said:

    maintenance is necessary! Trails used only by hikers
    require hardly any maintenance. Therefore, admitting
    bicycles to a park greatly increases its


    cost

    Quoted message said:

    of maintenance. Nothing is really "free", including trail
    construction and maintenance. (How does the saying go?
    "Beware of Trojans bearing gifts"?)

    10. But don't mountain bikers provide added safety, by
    being able to


    quickly

    Quoted message said:

    summon help in the event of an emergency? I would rather
    trust in a cell


    phone,

    Quoted message said:

    than a speeding mountain biker. Besides, natural areas are
    already one of


    the

    Quoted message said:

    safest places you can be. In over 50 years of hiking and
    backpacking, I


    have

    Quoted message said:

    never witnessed any situation requiring emergency aid.
    Most people go to


    natural

    Quoted message said:

    areas partly for solitude. If we wanted to be around
    large, fast-moving


    pieces

    Quoted message said:

    of machinery, we would stay in the city!

    I believe what cc meant is that using four letter "profane"
    words might encourage others to read and thus insight
    interest in the message you are trying to convey because it

    Frequently Asked Questions about Mountain Biking Michael
    Vandeman, Ph.D. March 5, 2004

    So mountain bikers are responsible for the extinction of the

    don't you?

    1. Why do people mountain bike?

    Now that's a question worth discussing!

    There are as many reasons as there are mountain bikers. Some
    do it for the exercise, some for the scenery, some just
    enjoy being outdoors on a bike. Some enjoy the challenge of
    a hard climb. Others get an adrenaline rush from riding
    downhill. To some it's a comptetitive sport. To others it's
    simply recreation. Some pride themselves on finesse--
    "cleaning" a section of trail without putting a foot down.
    Others take pride in getting through the same section with
    out falling down.

    For some, it's the company and cameraderie of other riders.
    For others, it's all about silence and solitude. Some
    mountain bikers ride without stopping and stay focused on
    the trail. Others carry binoculars or cameras, stopping
    frequently to watch birds or photograph wildlife.

    We are often passionate about riding and protective about
    the trails we ride. We love them no less than those who
    travel by foot or horse. We don't want our trails turned
    into housing developments or golf courses.

    If you want to know why people mountain bike, don't ask a
    failed academic who can barely ride a bike. Ask the people
    who are out there riding!

    And the rest of us mortals just enjoy the fall if we
    have it, get back up and keep riding (if we can),
    instead of complaining to the world about how
    "incomfortable" the ride was.
