Answer:
 30 percent tree cover - 2000 - 2009JPEG ... of forest cover vary widely—as much as 6 percent of Earth's land area, or the equivalent area of China.

The species was a keystone species.
Keystone species are the species that ''hold the ecosystem together''.
They have an important role in the trophic networks (food chains) and often they can even afflict changes in the abiotic part of the ecosystem (change the composition of soil, purify the water, lower the effect of the wind etc)
Therefore, when a keystone species is removed it affects greatly the whole ecosystem.

The conclusion that can be drawn from the last statement is that ALL THE ANIMALS LISTED ABOVE ARE HYBRID ANIMALS.
Hybrid animals are those animals that are produce from the interbreeding of two animals that are of different species but which come from the same genus. Hybrid animals can not produce fertile offspring because they do not possess viable sex cells, that is, they do not have the capacity to reproduce sperms or eggs.
