Keystone species - Wikipedia, the free encyclopedia "The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity."

Keystone Species refers to an organism that plays a critical role in its environment, one that may become apparent only once it is removed from an ecosystem. Keystone species exerts a strong influence on the structure and function of ecosystem. Let us have a look at some of these “KEYSTONE” species.

December is mistletoe season! Mistletoe was once considered a pest that kills trees, but was recently recognized as an ecological keystone species (an organism that has a disproportionately pervasive influence over its community).  A broad array of animals depend on mistletoe for food, transfer pollen between plants, and disperse the sticky seeds. They remain "evergreen" and provide a source of cover and food for birds like this over-wintering Eastern bluebird.
