  • Desert degradation is usually caused by a set of interlocking factors

  • These include the fragility of the desert environment, flawed economics, weak laws and regulations, and human "needs" for immediate gratification

  • A doctor can't cure many diseases without treating the causes, neither can we



  • The desert remains under unprecedented assault from development, infrastructure, air pollution, nitrogen deposition, invasive species, military operations, mining, and OHV activity

  • OHV activity is the least necessary, very extensive; and very damaging

  • The full extent of OHV damage remains unknown

Hill climb damage

Hill climb damage



  • Plant communities are disrupted by direct impacts, crushing, and damage to roots

  • Weed invasions are may make desert ecosystems much more vulnerable to fire

  • Compaction is often severe in heavily used areas and infiltration can be very limited

  • Water flow changes and erosion increases

  • Reduced levels of hyphae and bacteria are found

Damage is extensive

Damage is extensive

  • The most apparent level of OHV damage is total destruction of all vegetation in high use areas

  • Even in areas of moderate use the damage is quite extensive, although to the untrained eye it may appear less severe if the larger shrubs are still standing

  • Extensive use of desert washes for OHVs has been a disaster for wash ecosystems

  • Understanding the allure of OHV operation is not difficult “its fun”

  • OHV exploration (the more sedate part of the population) enables families to discover new areas and enjoy the beauty of the desert

  • It makes it easy to reach remote areas for camping

Ohv play areas

OHV play areas

  • OHV play is noisy, involves speed and power, danger, and requires intense concentration

  • A small percentage of the OHV population needs the added "kick" of outlaw behavior

  • Flouting route restrictions, damage of undisturbed areas, vandalizing gates, signs, and displays, smashing plants

Extremely difficult and costly to repair

Failed education

Failed education

  • The OHV community, like most Americans, have "affluenza", falling prey to relentless and sophisticated advertising, "If I just have more, I'll be happy"

  • Poorly educated by a failed school system, they also have no concept of ”Nature's Services", ”Natural Capital", and "sustainability"

Economics it s the economy stupid

Economics“It’s the economy, stupid”

  • The OHV community of manufacturers, retailers, and suppliers and their advertising agencies and dependents is big business.

  • The economic impact is $5-10 billion dollars a year in California.

  • More than 40% of the money spent on OHVs is for vehicles and almost 10% is for fuel.

Flawed accounting

Flawed accounting

  • Existing economic analyses neglect environmental affects and uncompensated costs to taxpayers

  • This provides a picture of OHV economics that is so misleading it would make Enron's accountants blush.

$econ activity minus damage $eco = less than zero






Autistic accounting

Autistic accounting

  • Neoclassical economics says value is determined by sales price or use value, perhaps $500 to $700 per hectare

  • Ecological economics says a better way to judge value is replacement cost, perhaps $50,000 per hectare

  • Knowing this we can say that a full size 4x4 can do $40,000 dollars of damage in a day of ripping across the virgin desert

Restoration experience has illustrated the high repair costs

Other uncompensated costs

Other uncompensated costs

  • Some could be determined, but haven't been well studied; while others are quite challenging to cost

  • Medical treatment, perhaps $20-30 million a year

  • Enforcement

  • Cleanup and repair of facilities and fixing vandalism

  • The economic cost of Global Change

  • The economic cost of weed control

  • The economic cost of increased fire risk

Cost related to natural capital and nature s services

Cost related to Natural Capital and Nature's Services

  • What is the value of biodiversity? Of beauty?

  • Of endangered species? Of natural hydrologic function? What is the ecological cost of exotic species invasion?

  • What is the ecological cost of increased fire?

  • The ecological cost of nitrogen deposition?

  • What is the ecological cost of global warming?

  • Almost certainly these are in the billions...



  • Subsidies - you gotta love ‘em!

  • Analysis of automobile operation in the U.S. suggests we all get about a 90% subsidy

  • OHV operators are currently getting a subsidy closer to 99%, but users complain heavily about existing fees

  • An OHV green sticker costs only $12.50 a year, just $50 a year for an OHV park pass, or $90 a year for an Imperial Dunes pass

  • In contrast $120 a year for a state park pass!

Ohv industry profits taxpayers pay

OHV industry profits, taxpayers pay

  • The OHV industry is mining the value of the desert at the expense of the desert owners (the American public) and future generations

  • The value of the desert's scenic beauty, ”Natural Capital", and ”Nature's Services" is being exported to Japan and Detroit

  • While the beneficiaries pay lip service to "tread lightly", advertising almost always shows the "tread heavily" mode

The future

The future

  • Desert destruction and restoration is not primarily a technical problem

  • The root cause of desert destruction is ultimately poor accounting

  • It will be difficult to do anything about the enormous problem of desert deterioration until we address these “drivers”

  • Until we do, we are as the Dutch say, "mopping up the floor without turning off the water”

The education problem

The education problem

  • Users need to be aware of costs, impacts, and responsibility

  • Control of the outlaws is most important, responsible off-highway recreation is less of a problem

  • I like OHV activity but don’t ramble off route, just as I would like to shoot skeet in the Crystal Palace but don’t

Just because it s fun doesn t mean it s right

Just because it’s fun, doesn’t mean it’s right

Skeet shooting in the Crystal Palace would be fun!

Manufacturers should play a bigger role in tread lightly

Manufacturers should play a bigger role in “tread lightly”

  • A special sales tax on OHVs (5- 10%) might be desirable

  • OHV manufacturers should be charged $50-100,000 for each advertisement exhibiting "tread heavily" behavior

  • If a park pass costs $120 a year, then an OHV pass should probably cost $1,000 a year

  • If a ski pass costs $36 a day, then an OHV pass should be probably cost $100 a day

  • Implementing this level of fee would be politically unfeasible, but perhaps $250 a year would be plausible

Taxes and fees would help pay uncompensated costs

Taxes and fees would help pay uncompensated costs

  • Medical system costs

  • Better management, enforcement

  • Critically needed funding for research (Recovery and Vulnerability $50 million year)

  • Active restoration program ($50 million year)

  • Money to develop new, high quality OHV play areas on lands removed from agriculture due to water transfers

  • Funding for new OHV play areas closer to urban areas
