Yellowstone wolf pack territories in 2011. Wolf population declines, when they occur, result from "intraspecific strife," food stress, mange, canine distemper, legal hunting of wolves in areas outside the park (for sport or for livestock protection) and in one case in 2009, lethal removal by park officials of a human-habituated wolf.

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 ...
OR-7, also known as Journey, was a male gray wolf that was electronically tracked as he migrated from the Wallowa Mountains in the northeastern corner of the U.S. state of Oregon to the southern Cascade Range. 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.

Facilitation cascades have far-reaching ecological impacts on the diversity and function of the ecosystem as the positive effects of a subset of organisms cascade through the community, as in trophic cascades. The effect size of facilitation cascades can rival or exceed that of trophic cascades, and the main distinction between the indirect ...
