How Not to Save Wild Tigers

Captive tigers in the U.S. have become the latest target of a misguided campaign aimed at saving their wild brethren. According to the World Wildlife Fund, perhaps 5,000 captive tigers live in the U.S., many of which are privately-owned pets – more than the estimated 3,200 that survive in Asia in the wild. WWF has called for a ban on private ownership of tigers and proposed various other laws at both federal and state levels to control the U.S. captive tiger population. Why? Because WWF fears that body parts from captive U.S. tigers may enter the illegal trade and “stimulate demand” in Asia, leading to further poaching of wild tigers.

WWF will no doubt celebrate the recent passing of a
New Jersey Senate bill
that establishes new strict in-state permitting requirements for captive
tigers “to prevent their illegal trade.” This measure is being held up as a
model for the rest of the country to follow. However, some New Jersey
residents are skeptical about this bill and wonder whether this is not a
misguided allocation of the state’s resources (see comments
here). They are
right to be skeptical.
First, a
2008 survey by TRAFFIC, the WWF-affiliated trade monitoring
network, did not find any evidence whatsoever that U.S. captive tigers were
involved in illegal trade in tiger parts. Second, a
recent census by the
U.S. Feline Conservation Federation documents only 2,884 tigers, most of
which are found in licensed zoos and sanctuaries. Third, of those, only 24
are found in New Jersey, spread over 5 zoos. Even if body parts from those
tigers did enter the trade (highly unlikely) the effect would be trivial.
Not only is the New Jersey bill of questionable relevance, its basic premise
is also flawed. WWF’s assertion that body parts from U.S. captive tigers
must be kept away from the market to protect wild tigers is in fact
illogical. It assumes that if the supply of a product to the market is
increased, the demand will automatically increase by an even larger amount,
thereby leading to a price increase. This would make tiger products a
retailer’s dream — a unique product that actually rises in price as supply
increases.
In reality, if body parts from captive tigers were supplied to the market,
their price would most likely drop (in line with basic principles of supply
and demand). And lower prices would mean reduced rewards and incentives for
poaching and illegal trade. The theoretical argument for trade stimulating
demand is phony. What about empirical evidence? Conservationist Brendan
Moyle analyzes data from the commercially-exploited Louisiana alligator
population and
finds no correlation to support WWF’s claimed relationship.
The argument that the U.S. captive tiger population poses any sort of threat
to Asia’s wild tiger population is based on nothing more than dubious
conjecture and WWF’s campaign probably amounts to little more than a waste
of donors’ and taxpayers’ money.
