Landmark is ASC's groundbreaking project to provide "boots on the ground" support for the American Prairie Reserve management team. Wildlife survey crews consist of skilled outdoors men and women who live and work on Montana's northern Great Plains, collecting data that informs APR's conservation management decisions.  By Meghan Riehl We often stumble upon prairie dog towns while hiking transects, and are greeted with surround-sound chirps as the animals call out to warn each other of the tall bi-pedal creatures. Black-tailed prairie dogs inhabit grasslands and sagebrush in extensive underground burrow systems. A keystone species, their colonies create a habitat that benefits more than 150 others. They're a food source for many animals, including coyotes, eagles, badgers and the endangered black-footed ferret, according to National Geographic. At the end of July, our Landmark crew spent some of our free time helping a team of prairie dog biologists and field technicians.

Adjacent to American Prairie Reserve, the CMR – together with the UL Bend National Wildlife Refuge – encompasses 1.1 million acres spanning about 125 air miles along the Missouri River, from the Fort Peck Dam west to the boundary with the Upper Missouri River Breaks National Monument. The biologists are working to bolster the prairie dogs against the Bubonic Plague, which is carried by fleas and can devastate a colony, affecting the entire ecosystem. To do so, the scientists trap the prairie dogs, tranquilize them, comb them for fleas, pluck whiskers and hairs, weigh them, take blood samples, put in tracking chips, and mark them with ear tags. They capture them using bait with a plague vaccine, then use the whiskers to determine if the animals have eaten the bait. Blood samples determine if the vaccine is working.  Many other species including burrowing owls use prairie dog burrows as homes.

I like imagining the animals lounging down in the burrows on dirt couches to stay cool, with dirt-furnished living rooms, kitchens and bedrooms. In reality, their tunnels extend vertically down from the entrance 3-10 feet, and continue horizontally for another 10-16 feet with some connecting tunnels here and there.
