---

The latest pup counts have been released for the wolves in the Greater Yellowstone ecosystem. I have posted a number of updates previously this year, but this is the most complete.

Below are the number of pups by pack this year, and compared to last year -- 2001.

In total 100 pups have been counted at mid-summer. compared to 77-79 at the end of 2001.

Packs that reside primarily inside Yellowstone National Park-

TOTAL wolves	43	65	131 + 1 loner

* this was really just a pair of wolves that was thought might be a breeding pair
** 2 separate females -- former Druids -- had separate dens but later combined the pups

 

Packs that reside mostly or entirely outside of Yellowstone National Park-

Pack	Pups at end of 2001	Pups as of mid-Aug 2002	Size of the pack at the end of 2001

* The 2 of the 3 remaining members of the Gravelly Pack were control killed early in 2002
** The official count of wolves for the Greater Yellowstone was 218, but has you can see the count was not exact. 218-227 better reflects the count.
