Sahara Desert Has One of the Lowest Population Densities
January 8th, 2010 Dustin Politically, the Sahara lies largely in Morocco, Algeria, Tunisia, Libya, Egypt, Mauritania, Mali, Niger, Chad and the Sudan.
The Sahara Desert, covering most of North Africa, is the largest desert in the world. From north to south the Sahara is between 800 and 1200 miles and is at least 3000 miles from east to west. Due to the massive size of the Sahara, Africa is split into two regions that which lies above or forms part of the Sahara and the rest of Africa south of the Sahara. On the west, the Sahara is bordered by the Atlantic Ocean and on the east by the Red Sea and to the north are the Atlas Mountains and Mediterranean Sea.
Over 25 percent of the Saharas surface is covered by sand sheets and dunes. There are numerous rivers that originate outside of the Sahara but then enter the Sahara through underground waterways or by contributing to sources of surface water
The Saharas climate consists of basically two sub climates. A dry subtropical climate in the north and a dry tropical climate in the south. The dry tropical climate is generally characterized by mild, dry winters, a hot dry season just before the rainy season, and an annual temperature cycle. The dry subtropical climate, however, is characterized by annually high temperature ranges, cold winters, hot summers and two rainy seasons. There is a narrow strip in the western portion of the Sahara, along the coast, which generally has cool temperatures compared to the rest of the Sahara because of the influence of the cold Canary Current.
The Sahara is sparsely covered with various types of vegetation ranging from grasses, shrubs and trees in the highlands.
Some of the mammal species found within the Sahara is the gerbil, jerboa, Cape hare, the desert hedgehog, Nubian wild, spotted hyena, common jackal, sand fox, and the slender mongoose. The Sahara also contains over 300 species of migratory bird populations along with water and shore birds and various other types of birds. Some of the most common birds are ostriches, raptors, secretary birds, and guinea fowl. Numerous types of reptiles including frogs, toads and crocodiles can be found within the Saharas lakes and pools of water, while lizards, chameleons, skinks, and cobras are to be found among the dunes and rocks. Among the reptiles in the Saharas rivers and pools can be found snails, brine and algae shrimp.
The Sahara Desert covers over 3. 5 million square miles and has only 2. 5 million inhabitants roughly 1 person per square mile which is one of the lowest population densities on earth.

Proof of Life in the Sahara Desert
January 1st, 2010 Dustin Living and surviving in the Sahara Desert is very challenging to animals, plants and people. They must adapt themselves to the very hot climate and find ways to survive. Sahara Desert is a place seemingly uninviting to living creatures. However, there are previous evidences of desert life. Sahara Desert has adequate landforms and oasis although it is made of compact rocky land and shaped into plateaus. Sahara Desert allows animals to find their shelter and survive in this kind of environment. Recently, the most numerous are cattle. Today, many species found in this desert include foxes, gazelles, desert hedgehog, gerbils, jerboa, deer, and baboon. These are joined by spotted hyena, jackal, Libyan striped weasel, the slender mongoose, and hares. Over three hundred migratory bird species live here. Some of the most common birds found are ostriches, raptors, and ravens. Several types of reptiles such as frogs, toads and crocodiles; snails, brine, shrimp, and other crustaceans are found within the lakes, river and pools. Lizards, chameleons, skinks, and cobras are found among rocks and sand dunes. Most desert animals spend their daytime underground, unexposed to the sun. They also eat foods rich in water content to help them survive. They hunt for foods during night time because it is cooler. They are usually small in size to reduce water loss in their body. The Sahara Desert is very far from the animal-free climate because many living creatures call this place a home. Additionally, over thirty thousands petrolyphs or primitive drawings of animals such as crocodiles and the fossils of dinosaurs are found in the area of Sahara. This is evidential proof of life and existence. Many types of plants grow in the Sahara Desert. Grasses like Eragrostis, Panicum and Aristida are abundant. Trees such as Acacia and Atemisia and the shrubs like doum palm, and date palm are the common. These planta are saline-tolerant, also found in saline depression area. They are adaptable to the excessive heat and precipitation. Plants need enough water for survival. Desert plants must adapt to very hot and harsh state. For example, the cactus plant has spines instead of a broad leaves to minimize too much loss of water and thick stem to store water in a plant’s body for a long period of time. Some plants possess very long roots that go deep down to the earth to be able to survive in hot and dry place. Most plants grow in oases and along the river beds which water is present. Nomads are the majority of the people living in Sahara Desert. They constantly move from one place to another to improve their living conditions. They usually wear a headdress called howli to protect them from excessive heat, and long woolen fine clothes called barracans for protection from the intense heat of the sun. They eat rice and dates. They also eat camel or sheep meat because these are abundant around them. Another group of people that dwell in Sahara Desert are the Berbers. They are mostly found in Morocco and in Algeria. They reside in the place where they can raise animals like cattle and sheep. They even plant crops mainly for their own consumption. Berbers used to stay in stone houses, in clay huts or in tents so they can easily move to other places. Their houses are cool inside even without air conditioning. During day time, most people stay inside their house. If they go outside, they wear loose clothes to keep themselves out of the sun.

Desert Plants, sahara desert plants,
November 28th, 2009 Dustin The plants that call the Sahara home are a vital resource for both the animals and the people that call the millions of square kilometers of the Sahara home, and over time they have adapted amazing resources that allow them to survive in an area where months can go by without so much as a rain cloud in sight. Types of Plant Life Found in the SaharaThe Sahara desert is the world’s largest hot desert, spreading across 8. 6 million square kilometers of sand and oases in Northern Africa throughout the countries of Algeria, Chad, Egypt, Libya, Morocco, Mauritania, Mali, Niger, Sudan, Tunisia and Western Sahara. (Yes, there is such a thing as a cold desert-but that’s a topic for another day. ) Of those 8. 6 million square kilometers, however, only 200,000 are fertile, fed by an intricate system of underground rivers, reservoirs and artisan wells. The largest challenge that plant life faces in the Sahara is the lack of rain. Plants, like all living things, need moisture to survive. In an area where the average rainfall is four inches per year, approximately as much as many southern regions of the U. S. receive in a single thunderstorm, that’s not an easy requirement. That isn’t the only challenge these plants face, however. The wide expanse of the Sahara means that it is home to one of the largest varieties of topical features on earth. The highest point of the desert is 11,204 feet above sea level at the top of Mount Koussi, an extinct volcano in northern Chad; the lowest is 436 feet below sea level in the Qattera depression in Egypt. There’s nothing uniform about either the appearance or the form of the Sahara. Areas of the Qattara depression and other areas in which the soil is rich in saline are home to a wide variety of halophytes, plants that thrive in salty habitats. Date palms are a common example. The highlands and more arid regions of the Sahara are home to Xerophytes, plants that have over time adapted to life in areas with very little precipitation and have learned to conserve and make the most of the moisture available to them. There are several primary adaptations of Xerophytes that allow them to thrive in the dry regions of the Sahara:1) Many plants have developed extensive root structures that allow them to reach up to 80 feet or more into the ground, connecting them to underground water sources that ensure they remain hydrated in between storms. 2) Succulents such as cacti and their African equivalent, the euphorbia (Euphorbia actinoclada is shown in the illustration to the right), have learned to conserve the moisture they receive each year, absorbing large amounts of water when it rains and storing it in their fleshy stems or leaves in preparation for drought. These plants have adapted even further by modifying their broad leaves into spines to prevent excessive loss of water as the result of evaporation and typically have a vast, shallow root system that rapidly absorbs as much water as possible when it reaches the ground. 3) Small, flowering plants known as ephemerals (annuals) have shallow roots that allow them to absorb maximum moisture from the occasional rainfall. These plants complete their growing cycle quickly, producing seeds that lie dormant until after the next rain. Their brightly colored flowers attract the insects that are vital to their rapid pollination. 4) Grasses develop an extensive root system that allows the roots to live deep in the soil even when the visible portion of the plant has died-or been scorched. 5) Geophytes spend the majority of their lives underground as bulbs, quickly producing flowers when the rains do come. Lilies and tulips are a common example of geophytes found in the United States, as shown in the excerpt below from “The Physiology of Flower Bulbs”, published in 1993 in the Netherlands; geophytes in the Sahara and other regions of the Mediterranean are greatly herbaceous and tend to have a notoriously long juvenile period. They may live underground for years before flowering. 6) Shrubs and small trees in the Sahara are very similar to those found elsewhere in the world, with an extensive root system that penetrates deeply into the earth and leaves that are shed during the hottest part of the year.
