The reintroduction of wolves into Yellowstone National Park is not helping aspen groves, despite declines in the number of elk, according to a new study.

The USFWS said wolf populations have exceeded biological recovery goals and are now thriving.
While it was feared the elk population would be at risk upon reintroduction, wolf numbers on Yellowstone’s northern range has grown to 84 and elk numbers have not declined appreciably.
The study conducted by forestry researchers supports a “trophic cascade” theory of ecological interdependence — extending to plants, animals, food chains and ecological zones.
The latest wolf casualty added to a growing number of declining wolves in New Mexico. In addition to the 11 wolves shot by government agents since 2003, 20 have died due to accidents in the agency’s recapture program, said CBD.
