	CREOSOTE BUSH (Site not responding. Last check: 2007-09-10)
		Creosote bush is one of the most common and important plants of the warm deserts (Sonoran, Chihuahuan and Mojave Deserts) of North America, but cold winters exclude it from the Great Basin Desert.
		A single creosote bush, in the shade of which (right-hand side) is a clump of the grey, spreading, mat-forming cactus termed clavellina (Opuntia schottii) The cylindrical stems of this plant - a cholla similar to the large, erect chollas) grow to only about 10 cm high.
		Creosote bush is the most drought-tolerant perennial plant of North America.

	Creosote
		Creosote is the name used for a variety of products: wood creosote, coal tar creosote, coal tar, coal tar pitch, and coal tar pitch volatiles.
		Wood creosote is a colorless to yellowish greasy liquid with a smoky odor and burned taste.
		Brief direct contact with large amounts of coal tar creosote may result in a rash or severe irritation of the skin, chemical burns of the surfaces of the eyes, convulsions and mental confusion, kidney or liver problems, unconsciousness, and even death.

	Creosote Bush - MSN Encarta
		Creosote Bush, common name for five related species of bushes of the evergreen family.
		An individual creosote bush can live for up to 100 years, but the crown of the bush also splits into several lobes that eventually bend over into the surrounding soil and develop their own roots and branches.
		Because these new shoots are genetically identical to, or clones of, the original bush, the spreading plants may be thought of as still constituting the original one.

	Creosote bush - Wikipedia, the free encyclopedia
		Creosote bush is most common on the well-drained soils of bajadas and flats.
		In terms of negative water potential, creosote bushes can operate fully at -50 bars of water potential and have been found living down to -120 bars, although the practical average floor is around -70 bars, where the plant's need for cellular respiration generally exceeds the level that the water-requiring process of photosynthesis can provide.
		Creosote bush commonly forms clonal colonies, which may be very long-lived; a ring of creosote bushes in the Mojave Desert is believed to be at least 12,000 years old.

	Medicinal Planst of the SW - Larrea tridentata
		Larrea tridentata, of the Zygophyllacceae family, commonly known as Chaparral or Creosote Bush, is a common inhabitant of the deserts of the Southwestern U.S. and Mexico (Chevallier, 1996, p.224).
		Creosote leaves are small and curled (Moore, 1989, p.27) with a yellow-green color, and have a "greasy-leathery" texture (Tilford, 1997, P.44).
		Another reason for the controversial use of Creosote bush is because of its "potential toxic effect on the liver" (Chevallier, 1996, p.224).

	Creosote Bush — fragrance of the desert:Southern New Mexico Travel and Tourism Information
		Creosote bush is hard to miss in Southern New Mexico - its wiry form and sparse olive-green foliage are often all you see on alluvial fans, mesas and other sandy or gravelly soils.
		Creosote bush's distinctive odor and the leaves' shiny appearance are due to a resinous, varnish-like coating which helps the plant keep from drying out.

	Desert Survivor - North America's creosote bush Natural History - Find Articles
		Since all of these creosote bush insects are of North American origin (not having migrated from South America along with the bush itself), their specializations presumably evolved as a response to the introduction and eventual dominance of this new resource.
		Given the tremendous adaptability of insects and their ability to generate large populations in a brief time, the question "Why does the world remain green (or brown, in the case of the creosote bush)?" joins "Why are there so many kinds of insects?" as another of the major issues in ecology.
		Creosote bush and its resident insects offer an exceptional opportunity to address these questions: the plant's small size allows us to identify its well-known insects and exhaustively count (even manipulate) their numbers, as well as to alter the top-down forces by restricting predator access to individual plants.

	Creosote (Site not responding. Last check: 2007-09-10)
		Creosote is the name used for a variety of products that are mixtures of many chemicals; those products include wood creosote, coal tar creosote, coal tar, and coal tar pitch.
		Creosotes do not occur naturally in the environment; they are created by high-temperature treatment of beech and other woods (wood creosote) or coal (coal tar creosote), or from the resin of the creosote bush (creosote bush resin).
		Creosotes and coal tars are complex mixtures of variable composition containing primarily condensed aromatic ring compounds or phenols; therefore, it is not possible to represent the chemical formula and structure for these materials.
