Meanwhile, wolf packs often claim kills made by cougars, which has driven that species back out of valley hunting grounds to their more traditional mountainside territory. [45] The top-down effect of the reintroduction of an apex predator like the wolf on other flora and fauna in an ecosystem is an example of a trophic cascade.
Recently another subspecies, the British Columbia wolf (Canis lupus columbianus), has established itself in the Cascade mountain wolf's past territory by following the Cascade Range through Washington and is now west of the Cascade Crest, [8] expanding across Oregon, [9] and into northern California to Lassen Peak, where in 2019 the Lassen pack produced 3 pups.
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...

After the wolf dispersed from his natal pack in 2011, he wandered generally southwest for more than 1,000 miles (1,600 km) through ...
English: This diagram illustrates trophic cascade in an environment. The cascade to the left shows a healthy ecosystem with a top predator, a primary consumer and a primary producer. The wolf at the top of the cascade is the top predator of the environment. The top predator makes sure that the deer and elk populations stay at healthy levels.
