>This article is about the biological organisms known as trees. For other meanings of the word see tree (disambiguation). A tree can be defined as a large, perennial, woody plant. Though there is no set definition regarding minimum size, the term generally applies to plants at least 6 m (20 ft) high at maturity and, more importantly, having secondary branches supported on a single main stem or trunk (see shrub for comparison). Compared with most other plant forms, trees are long-lived. A few species of trees grow to 100 m tall, and some can live for several thousand years. See more at Wikipedia.org...

>This article is about the animal. For the programming language, see Squirrel programming language. Many, see the article Sciuridae. Squirrel is the common name for rodents of the family Sciuridae (from Greek skia shadow and oura tail i.e. "tail that casts a shadow"). In everyday speech in the English-speaking world it usually refers to members of the genera Sciurus and Tamiasciurus. These typical members of the family are tree squirrels with large bushy tails, and are native to Europe, Asia and the Americas. Similar genera are found in Africa. However, the Sciuridae also include flying squirrels, and ground squirrels such as the chipmunks, prairie dogs, and woodchucks. The unrelated family Anomaluridae also have "squirrel" in their common name, though they are usually referred to as "scaly-tailed flying squirrels". See more at Wikipedia.org...
