The raccoon was once a protected species in Germany, but has been declared a game animal in 14 of the 16 German states since 1954. [265] Hunters and environmentalists argue the raccoon spreads uncontrollably, threatens protected bird species, and supersedes indigenous competitors. [88]
Population sizes are largely unknown, though the Cozumel raccoon is critically endangered, with around 200 individuals left, and the Eastern mountain coati is endangered. No procyonid species have been domesticated, although raccoons are sometimes kept as pets.
Grazing species such as plains bison, which is another keystone species, the pronghorn, and the mule deer have shown a proclivity for grazing on the same land used by prairie dogs.

Procyon is a genus of nocturnal mammals comprising three species commonly known as raccoons in the family Procyonidae. The most familiar species, the common raccoon ( P. lotor ), is often known simply as "the" raccoon, as the two other raccoon species in the genus are native only to the tropics and are less well known.
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagous, eating one specific type of food ), others less so, and some can tolerate many different ...
The loss of a keystone species results in a range of dramatic cascading effects (termed trophic cascades) that alters trophic dynamics, other food web connections, and can cause the extinction of other species. [92] [93] The term keystone species was coined by Robert Paine in 1969 and is a reference to the keystone architectural feature as the ...
