Study Says Yukon-Charlie Wolves Healthy, Population Rebounding

An 18-year National Park Service study, of wolves monitored by radio collars, says the Yukon-Charlie Preserve's population is healthy and rebounding.
The 2.5 million acre protected land area is located in northeast Alaska, along the Canadian border.
A couple of weeks ago biologists made their latest helicopter trip, looking for wolf tracks in the snow.
After being tranquilized, a collar was installed on a three-year-old female.  It gives officials weekly email updates about things like where she lives, travels, and how big of a home range she has. 
"This is the Iron Creek pack," biologist John Burch says.  "We're putting a second collar in the group because we try to keep two radio collar wolves in each pack, no matter how big the pack may be, because you never know when the wolf may disperse or die, or the radio collar may fail."

Since 1993, National Park Service officials have been able to determine the fate of 139 wolves using the radio collar technology.  Currently, biologists say out of the nine Yukon-Charlie packs they track more than seven wolves can be found in an average pack.
