I gather you’re not opposed to hunting to fund conservation?
Do I think there could be a place for sustainable hunting, and the benefits go back to conservation? Yes, I do. Tigers are on the edge. I spent 30 years trying to save tigers. If hunting can be done in a manner that doesn’t affect reproduction — you are not taking reproductive females, and you’re taking older animals — if there can be a valid means of showing that taking trophies in the hunt truly benefits the survival of the species or the ecosystem as a whole, then I could see my way to that. That’s the reality of the world.
From being around them, I knew there was something special and different [about them]. They behave and look at you differently than other big cats. This concept of “jaguarness” is: How come jaguars are doing so much better than the other big cats? It’s not just luck. Jaguars never rush into something. The jaguar watches, waits and evaluates. Most of the time, it walks away. People have called the jaguar a coward. It can break the necks of three dogs at once, but it realizes that fighting is not a good survival technique unless you have to. [Jaguarness] is a combination of evolution, behavior, the jaguar’s anatomical structure.
It
was toward the end of the work day [in Belize]. I saw a big, new male
track, then I lost it. I kept on going, but it was getting dark and I
realized that I couldn’t be caught out without a flashlight. I turned
around, and the jaguar was in back of me. He circled around me and was
about 25 feet away. I was shocked. I had never been that close to a
non-drugged jaguar outside of a cage. It wasn’t aggressive. I walked
toward him, thinking he would walk off. He stood there. I squatted and
tried to appear non-threatening. The jaguar sat down, too, just looking
at me. I wish I could have enjoyed the moment, but I was terrified. This
250-pound animal could kill me in a single leap. I could fight and
there would be no way to overcome this beast. I stood up and stepped
back. I knew not to run. Then I tripped and fell. He stood up, growled
and walked [away from me] over to the edge of the forest. He looked back
at me and disappeared. It was incredible. It confirmed my feelings, and
those of many others that live with jaguars, that they do not want to
harm people once they assess that there is no danger. Still, being faced
with the Rocky of predators, knowing that there is no escape if he
wishes to kill you, takes one’s breath away.
What’s the biggest threat to the jaguar today? Hunting, the loss of habitat and hunting of the jaguar’s prey. It’s down to 50 percent of [its original] habitat. [The loss of habitat] has been stabilized, but people are still killing jaguars. Killing jaguars as a sport is everywhere. That’s a real problem. Illegal hunting of jaguar’s food is done everywhere. Fortunately, the jaguar is adaptable. They have one of the most diverse and opportunistic diets of any of the big cats. With the strongest jaws, per pound of weight, of any of the big cats, these massively strong animals can take down a 2,000-pound bull and drag it into the forest. Sometimes they go after the 1,000-pound tapirs with whom they live. But one of their favorite, though not easy, prey are the peccaries, which roam in groups and can tear apart a jaguar with their knifelike tusks if they get riled enough. But jaguars love to eat them and they will follow a herd to try and pick off young ones or slackers. Often, however, jaguars survive on smaller prey — agoutis, armadillos, paca, coati mundi, small ground-dwelling birds and even sometimes snakes and iguana.
Jaguars are doing better than the other big cats elsewhere because they had a respite. During the Spanish and Portuguese colonization [of Central and South America in the 16th and 17th centuries], disease killed off 90 percent of the indigenous people. As a result, the forest grew back and the jaguars recolonized Central America from South America.
Not as many as 100,000, but more than 20,000. We are trying to figure out that number.
The
Jaguar Corridor is a genetic corridor. In the late 1990s, we found that
we could get DNA material from jaguar fecal matter. When [biologists]
looked at the feces from Mexico and Argentina, we realized it was the
same animal. It is connected genetically through its entire range. Then
we said, “How could this be? It exists all the way from Mexico to
Argentina, with the Panama Canal in between.” I knew that in order to
preserve the Jaguar Corridor, there had to be some top-down official
recognition of it. We wanted this corridor to be zoned, like other
lands, so that this citrus grove or cattle plantation was part of the
Jaguar Corridor [so the cat would be allowed to pass undisturbed]. We
spent a decade . . . checking out the lands of the
corridor, quadrant by quadrant. We put up camera traps and did surveys
to get proof that they were using that area. Once we had that data, we
went to the countries’ heads of state.
The
greatest hedge against extinction of any species is genetic diversity.
You don’t want brothers and sisters marrying or royal families mixing,
because inbreeding often leads to certain diseases. . . .
With the Jaguar Corridor, we have mostly young males walking back and
forth between areas. That’s enough to insert their DNA into another area
so the diversity maintains itself from Mexico to Argentina. That’s a
reason for the jaguar’s success.
Why do we need the jaguars? Lots
of forest have lost their top predators or big cats and they still look
good. But now we know beyond a doubt that removal of the top or apex
predators like jaguars from a natural system changes that system
irrevocably; it changes and weakens the stability of the environmental
interactions. We are also now becoming more aware of the increase in
reemerging infectious diseases — SARS, West Nile virus, Ebola, Lyme
disease. Up to 75 percent of these diseases and all of the ones I just
mentioned are zoonotic, meaning that they involve an animal host.
Undisturbed natural systems act as firewalls for these diseases, keeping
them in check. When that firewall is destabilized, the diseases cross
over more easily into the human’s world.There is no evidence of any resident populations. Jaguars from northern Mexico are clearly trying to come over.They turn around and come back to Mexico or they get shot. They don’t establish themselves [in Arizona]. If no breeding population exists, it will be almost impossible for dispersing young males to establish a resident population.
Absolutely. The jaguar is one of the most successful, resilient and powerful big predators in the world. It has survived for approximately 4 million years, through major climatic changes during the ice ages of the Pleistocene, when most of the other large-bodied cats of the world went extinct. But since modern man, Homo sapiens, has come on the scene throughout the jaguar’s remaining range in the New World, human activities and land use are the major threat to this species’s existence.
The jaguars can adapt and survive climate change; they have done that many times before. But they must be allowed to move through the environment as they have done for millions of years. This is the essence of the Jaguar Corridor that I’ve been working on for nearly 15 years.
I believe in the resiliency of the jaguars, and as tough as it is, I believe in the intelligence of the human race. These animals are very necessary for the health and well-being of the rest of the jungle species as well. We are starting to understand that.
