Keystone Species are species who
enrich ecosystem function in a unique and significant manner
through their activities, and the effect is disproportionate
to their numerical abundance. Their removal initiates changes
in ecosystem structure and often loss of diversity. These
keystones may be habitat modifiers (ie. cottonwoods, rushes
and ironwood), keystone predators (ie. puma and coyote)
or keystone herbivores (ie. prairie dog and beaver).
