What if it disappeared?

Impact Low
Decades before its near-disappearance

As a mid-sized predator of the southeastern United States, the red wolf likely regulated populations of small and medium-sized mammals — but its collapse in the 1960s predated the modern tools of ecological study, and the specific effect of its disappearance was never directly documented.

Insufficient
Detail

Unlike the gray wolf at Yellowstone, whose reintroduction was scientifically monitored from day one, the red wolf had already nearly disappeared before the discipline of trophic cascade ecology developed. No before/after study documents what changed in its original ecosystem.

Today, 16 wild individuals

With a wild population this small, there is no longer a functioning ecosystem in which to measure the effect of its presence at the scale of the original population — only a captive breeding program keeps the species alive.

Insufficient
Detail

The red wolf is today the most endangered canid in the world. Its near-extinction largely already answers the very question this entry asks — what would happen if it disappeared? Its ecological disappearance from nearly all of its historical range has already occurred, without science having been able to document it in real time.
