From the assessing pre- and article-wolf reintroduction analysis, biologists can also be understand the environmental relationship among them variety. Once the personal dogs, wolves explore various other browse techniques than the solitary cougar, nevertheless the a couple of kinds victimize comparable pets.

Of the 88 cougars which were captured, 80 was in fact radio-collared.
Away from 1998 so you’re able to 2006, another phase of these browse was presented. Boffins monitored 83 radio-collared cougars, and fifty kitties into the 24 litters. Ranging from 1998 and 2005, researchers reported 473 understood or likely cougar eliminates. Elk comprised 74%: 52% calves, 36% cows, 9% bulls, 3% unknown sex otherwise many years.
