Cactus In The Desert Pdf Download

<div>Succulents are plants that can store water, a major advantage in an ar=
id ecosystem. Different adaptations allow them to thrive in areas with high=
 temperatures and low rainfall.</div><div></div><div></div><div></div><div>=
All cacti are succulents and are able to survive in the desert as a result =
of their many physical adaptations. They have roots close to the soil surfa=
ce that quickly collect rainwater. The stem swells during wet weather, and =
then contracts during a drought. The green stems photosynthesize throughout=
 the hot and dry summer. The waxy skin reduces the amount of water lost due=
 to transpiration. The spines provide shade, break up wind currents, and pr=
ovides protection. Cacti were used by native people for food, medicine, dye=
s, tools, and a variety of other uses.</div><div></div><div></div><div></di=

><div></div><div>Uses:</div><div></div><div></div><div>The cactus family is=
 one of the most easily recognized plant families in the world. Their beaut=
iful blossoms, thick stems and unusual shapes attract thousands of people t=
o the desert each year. Cactus, as a plant family, show variations between =
the individual species. They range from the three-inch fishhook cactus nest=
led in a rock crevice to the towering saguaro cactus which reaches heights =
of 30 to 40 feet. Cactus grow on rocky hillsides, alluvial fans and in barr=
en washes throughout the desert.</div><div></div><div></div><div>Cactus is =
an American plant family not native to Europe, Africa or Australia. Very li=
ttle is known about early cactus plants because only two cactus fossils hav=
e ever been found. The oldest, found in Utah, dates to 50 million years ago=
 and was similar to today's prickly pear.</div><div></div><div></div><div>C=
actus plants probably grew in a tropical environment until about 65 million=
 years ago when, in much of California, the climate changed from year-round=
 rainfall to a pattern of dry summers and wet winters. Later, when the dese=
rt began to form as the Sierra Nevada and Peninsular Ranges rose and blocke=
d rainfall to the eastern valleys, the cactus adapted to the dry, desert co=
nditions.</div><div></div><div></div><div>Although cactus are synonymous wi=
th desert regions, they are found in some unlikely places. In the lush, tro=
pical regions of Mexico, South America and some Caribbean Islands, tall col=
umnar cactus grow among hanging vines and large-leaved trees. One species g=
rows at an elevation of 11,000 feet in the Sierra Nevadas.</div><div></div>=
<div></div><div>Cactus owe their success in the desert to their structural =
adaptations. While other desert plants may have similar features such as sp=
ines and succulent stems, these evolutionary traits reach a zenith in the c=
actus.</div><div></div><div></div><div>Cactus take advantage of the lightes=
t rainfall by having roots close to the soil surface. The water is quickly =
collected by the roots and stored in thick, expandable stems for the long s=
ummer drought. The fleshy stems of the barrel cactus are pleated like an ac=
cordion and shrink as moisture is used up. These pleats also channel water =
to the base of the plant during rain showers.</div><div></div><div></div><d=
iv>When water is no longer available in the summer, many desert shrubs drop=
 their leaves and become dormant. Cactus continue to photosynthesize becaus=
e they have fixed spines instead of leaves. The green stems produce the pla=
nt's food, but lose less water than leaves because of their sunken pores an=
d a waxy coating on the surface of the stem. The pores close during the hea=
d of the day and open at night to release a small amount of moisture.</div>=
<div></div><div></div><div>The dense network of spines shades the stems, ke=
eping them cooler than the surrounding air. Many barrel cactus lean to the =
south so that a minimum of body surface is exposed to the drying effect of =
the midday sun. Cactus pay a price for these water-saving adaptations -- sl=
ow growth. Growth may be as little as 1/4 inch per year in the barrel cactu=
s, and most young sprouts never reach maturity.</div><div></div><div></div>=
<div>For many animals such as the bighorn sheep and the antelope ground squ=
irrel, cactus are an important source of food and water. The cactus wren an=
d California thrasher often build their nests in the buckhorn cholla. These=
 birds trim spines from the cactus to permit their own easier access, but r=
ely on the balance of the spines for protection from foxes, coyotes and pre=
datory birds. The Gila woodpeckers and gilded flickers, chop burrows in the=
 long arms of the saguaro cactus. Owls, flycatchers, and starlings also use=
 the abandoned homes in the saguaros as their abodes.</div><div></div><div>=
</div><div>Different varieties of cactus was used for food and medicinal pu=
rposes by Native Americans for thousands of years. The Cahuilla Indians spe=
nt the cooler months gathering wanted plants. They harvested the fruit of t=
he beavertail cactus for its sweetness. The fruit was cooked in a pit with =
hot stones for at least 12 hours, and the large seeds were ground into a mu=
sh. When the flesh pads were young, they were cut into small pieces, boiled=
 and served as greens.</div><div></div><div></div><div>Native women used ga=
thering sticks to harvest the buds of barrel cactus to prevent being injure=
d by the sharp spines. Usually these buds were parboiled several times to r=
emove the bitter flavor before they were eaten.</div><div></div><div></div>=
<div>Cactus are found throughout the desert regions and usually bloom in la=
te March through May. The blossoms range in color from the deep magenta of =
the hedgehog cactus to the cream-colored blossoms of the saguaro, and from =
bright yellow prickly pear to the pink blooms of the beavertail cactus.</di=
v><div></div><div></div><div>Cactus, highly adapted to the harsh desert env=
ironment, flourish in places where other plants cannot survive. Their survi=
val is threatened by "cactus rustlers" who steal these plants for the profi=
table landscaping trade. Some individuals destroy cactus by operating vehic=
les off the road while still others use these ancient plants for target pra=
