Search Results - Poaceae

Plant communities dominated by Poaceae are called grasslands; it is estimated that grasslands comprise 20% of the vegetation cover of the earth. Grass species also occur in many other habitats that are not formally considered to be grasslands, including different types of wetlands (e.g., fens, marshes), forests and tundra.

Poaceae is often considered to be the most important of all plant families to human economies it includes the staple food grains and cereal crops grown around the world, lawn and forage grasses, and bamboo, which is widely used for construction throughout east Asia and sub-Saharan Africa. Civilization was founded largely on man's ability to domesticate cereal grass crops around the world.

The term "grass" is also applied (incorrectly) to many grass-like plants that are not members of the Poaceae lineage, including the rushes (Juncaceae) and sedges (Cyperaceae). This broad and general use of the word ‘grass’ has lead to plants of the Poaceae often being called "true grasses".
