In the summer of 2010, Jennifer Day, a University of Washington
graduate student and “Scooby the Conservation Canine,” an energetic
black Labrador, were invited to spend four days in Jalisco Mexico's Primavera
Forest hunting for the scat of wild animals that roam the woods. Now
they are gearing up for a new project in the unsurveyed wilds of Montes
Azules Biosphere Reserve in the Lacandon rainforest of Chiapas, which
has the highest abundance of terrestrial mammal species per hectare in
all of Mexico.
Jennifer and Scooby are members of the Center for Conservation Biology
in Seattle, Washington, whose founder, Dr. Sam Wasser, pioneered
techniques for extracting DNA and hormone levels from animal scat,
which allow researchers not only to identify species and sex, but also
to pinpoint the identity of an individual animal. In addition, they can
tell whether that animal is undernourished, healthy, pregnant and even
whether or not they are stressed.
Although he had proven the value of droppings for studying animals,
finding those droppings in a forest or jungle proved a daunting task
for Wasser until he thought of using dogs to do the job for him. This
was the origin of the Conservation Canines, which can adroitly detect
the dung of Giant Armadillos, Spotted Owls and even sea dwellers like
Orca Whales, demanding for payment nothing more than a few minutes of
fun, playing with a bright red rubber ball.
The latest project of the Center for Conservation Biology will
concentrate on the Mexican jaguar in the Lacandon Jungle of Montes
Azules Park, just north of the Mexico’s border with Guatemalea. The
Jaguar project actually grew out of a flora and fauna study that has
been going on in Veracruz for several years.
“Scooby and I were there to survey for large mammals,” Day told me. “We
were looking for the scat of jaguars, pumas and tapirs. We did a really
thorough search job and we had a lot of success. People had thought
there were no more jaguars left in Veracruz, but actually they are
still there in the Uxpanapa Valley.”
The success of the Veracruz project has encouraged researchers to try
compiling data about jaguars all over the country in an effort to
understand the habits and problems of these elusive night prowlers.
They would like to know what attracts jaguars to a place or repels
them, what impacts their nutritional or psychological stress and what
prevents populations in separated areas from linking up.
The Center for Conservation Biology is now working with UNAM’s Rodrigo
Medellín, president of the Society for Conservation Biology and known
around the world as “The Bat Man of Mexico.”
Says Day: “The people working in Chiapas really want to find out what
the density of jaguars is in the region. There are no roads in the area
and the park has been protected for a long time, so it should be a good
habitat for jaguars, pumas and tapir as well as rare carnivorous bats
whose guano we will also be searching out. Because it’s so wild, with
so little access, it’s not possible to do the normal kind of wildlife
research. You can’t set up camera traps and revisit them once a month;
you can’t do radio telemetry experiments because normally you have to
be physically present multiple times. That’s what makes our method with
the dogs so great, because we can go through a really remote area, for
example hiking a ten-kilometer stretch, camping, then doing another
ten-kilometer stretch, and so on. We’ll spend many days making a big
loop, looking for jaguars, and that will be the first ever thorough
exploration of this area for these rare species.”
To help fund this project, Jen Day has set up a page at Experiment.com,
a website dedicated to crowdfunding scientific projects. The page is
called “Dogs, Cats, and Scats: Saving Jaguars, One Poop at a Time” At the moment, the researchers have
one grant—from the Animal Welfare Institute—to pay for one dog and
handler team, but because the Biosphere Reserve is so vast, White
believes they could do a much better job if they had a second or third
team. She says, “We could get a much better picture of how many jaguars
are there, what resources they’re using and what we need to do to
protect their habitat, not only in the Lacandon area, but across these
animals’ whole range in Mexico.”
Jennifer Day’s fund raising project began on October first of 2014 and she has
only until the last day of this month to reach either her short-term
goal of $10,000 for one more dog-and-handler team or the long-range
goal of $20,000 for a total of three teams. You can check how she's doing here. Donors’ credit cards
will only be charged at the end of October if the total amount of
donations has passed the $10,000 mark.
“What I’m really excited about,” adds Jennifer Day, “is that this will
be the third area in Mexico where we will have jaguar genetic samples,
meaning we will finally start to get a good picture of how these
different populations, around Cancún, Lacandona and Uxpanapa, are
connected to each other, and all the information we collect will go
into one big data base of genetics. I hope the crowdfunding approach
will work. Please remember: every little bit helps.”
