Well, not exactly. But they do communicate.
According to Dr. Constantine Slobodchikoff, professor
at Northern Arizona University and well-known animal behaviorist and
conservation biologist, prairie dogs have
a large vocabulary of yips and barks. Some are greetings, and others, like
their yip-jumps, appear to be play.
Much of their vocabulary consists
of warnings, and their barks differ depending on the type and location of a threat.
A warning about an approaching coyote differs from the warning about a
rattlesnake. These Animal Planet Videos demonstrate the various calls. (Sorry about the commercials.)

A keystone species plays a critical role in maintaining the structure of an ecological community because of its effect on other organisms. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed.

Their burrows help to channel rain
underground, reducing surface erosion and increasing the amount of water
reaching the water table.
Prairie dog tunnels also make
suitable habitats for other animals. Rabbits, salamanders, snakes, and
burrowing owls live in abandoned burrows, and badgers and coyotes have been
known to enlarge prairie dog burrows to form their own dens.

Finally, prairie dogs provide an
ample food source for other animals in the food chain such as eagles, hawks, foxes,
coyotes, badgers, and the endangered black-footed ferrets.
Unfortunately, many farmers consider
the prairie dog to be destructive pests which eat crops, compete with cattle,
and carry diseases. They shoot, poison, and even dynamite entire prairie dog
towns. Environmentalists have attempted
to have black-tailed prairie dogs listed as endangered.
Here is an informative passage from
Wikipedia. Prairie Dogs
"In
2000, the U.S. Department of the Interior declared the black-tailed prairie dog
“warranted” for listing as a threatened species, however the secretary was
"precluded from actually listing the species by more urgent
concerns". In 2004, the department declared that protection was “not
warranted.” The day after the U.S. Fish and Wildlife Service removed the
species from the candidate list, South Dakota announced its mass extermination
campaign in the Conata Basin, home to one of the two viable black-footed ferret populations remaining in
the wild. Tens of thousands of acres of prairie dogs were poisoned until 2006.
In 2007, conservation groups filed suit in U.S. District Court in Denver
challenging the secretary of the interior’s decision not to list the
black-tailed prairie dog as “threatened” under the Endangered Species Act. Forest
Guardians, Rocky Mountain Animal Defense, the
Biodiversity Conservation Alliance, and the Center for Native Ecosystems
contended that the livestock industry and land developers pressured the federal
government not to list the prairie dog."
How you can help
I
want to thank Abi Cushman for collecting this information on her site, Animal Facts.
If you would like to help the
black-tailed prairie dog, there are several things you can do. You can contact
government officials at the local, state, and federal levels advocating further
protection for black-tailed prairie dogs. You can also make donations to
charities trying to save the Great Plains and its wildlife like Wildlife Defenders or the American Prairie Foundation.
