By preying on the sickest, weakest, and slowest animals, they control the spread of disease and keep prey populations in check. Gray wolves are a top predator whose presence has a ripple effect on the rest of its ecosystem. Keystone species fall into several broad categories. Michael J. L. Peers. What factors determine cyclic amplitude in the snowshoe hare (Lepus americanus) cycle? The majority of the field work done in the Alaska parks in regard to invasive plants is done by park staff and internes working with and under the purview of the Invasive Plant Management Team (IPMT). In the boreal, keystone species also include trees like aspen and willow (these provide critical habitat for myriad organisms like lichens, fungi, insects, and birds) and plants like wild red raspberries, which are a critical food resource for animals from bees to bears. These pairs are often pollinators, like hummingbirds, that rely on specific plants for sustenance, and plants that rely on those pollinators to reproduce. Gillis, E. A. Ecol. Nat. Ecology 67:62938, Kaye JP, Binkley D, Rhoades C. 2003. Despite this, the Trump administration is attempting to roll back wolf protections instituted under the Endangered Species Act in 1974an action that would imperil the animals recovery. Biol. It may not be the largest or most plentiful species in an ecological community, but if a keystone is removed, it sets off a chain of events that turns the structure and biodiversity of its habitat into something very different. p 118, Paine RT. In any arrangement or community, the keystone is considered one of the most vital parts. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its .

In the 1960s, renowned ecologist Robert Paine disrupted a patch of Washington State coastlineand made a huge environmental breakthrough. Longitudinal patterns of ecosystem processes and community structure in a subarctic river continuum. Swift water and changing channelization can create dangerous crossing situations that have prohibited accessing the site in some years, leaving the plants untreated. In many cases, the vital role of a keystone species in an ecosystem is not fully appreciated until that species is gone.

By uprooting and eating vast quantities of small trees and shrubs that would otherwise convert to forest or scrubland, they are ecosystem engineers that preserve sunny, open spaces where grasses can thrive. Keystone prey, which include animals ranging from Antarctic krill to Canadian snowshoe hares, have a big role to play in the ecosystem.
