Common Sagebrush - Artemisia tridentata Common Sagebrush Common Name: Sagebrush, Big Sagebrush Genus: Artemisia Species: tridentata precipitation ranges from 12 inches to 40 inches a year. Sagebrush grows in dry places where other plants do not, but it prefers well drained soils in sheltered areas. it has shallow roots that are spread out below the surface to absorb the water. Sagebrush is used by Native Americans as a smudge herb (an herb burnt for the smell). Sagebrush is on no endangered species list, but doesn't grow in as many areas it used to. by Evan K. 2002 bibliography: "California Coastal Range Open Woodland--Shrub--Coniferous Forest--Meadow Province" "Species:Artemisia tridentata ssp.tridentata" W., Monroe.

Deserts Far from being barren wastelands, deserts are biologically rich habitats with a vast array of animals and plants that have adapted to the harsh conditions there. Some deserts are among the planet's last remaining areas of total wilderness. Yet more than one billion people, one-sixth of the Earth's population, actually live in desert regions. Deserts cover more than one fifth of the Earth's land, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. And despite the common conceptions of deserts as dry and hot, there are cold deserts as well. Desert animals have adapted ways to help them keep cool and use less water. Desert plants may have to go without fresh water for years at a time. Some of the world's semi-arid regions are turning into desert at an alarming rate. Global warming also threatens to change the ecology of desert.

Elk, Elk Pictures, Elk Facts Elk are also called wapiti, a Native American word that means "light-colored deer." Elk are related to deer but are much larger than most of their relatives. A bull (male) elk's antlers may reach 4 feet (1.2 meters) above its head, so that the animal towers 9 feet (2.7 meters) tall. Bull elk lose their antlers each March, but they begin to grow them back in May in preparation for the late-summer breeding season. In early summer, elk migrate to high mountain grazing grounds where the cows (females) will give birth. During the late summer breeding season the bugling of bull elk echoes through the mountains. In the winter, wapiti reconvene into larger herds, though males and females typically remain separate. Elk were once found across much of North America but they were killed off and driven to take refuge in more remote locations.

Information on Desert Climates Deserts represent one-fifth (20%) of the land surface of the world. The majority of deserts are in the Arabian Peninsula, Australia, The Americas, North and South Africa, India and Pakistan. The largest desert is the Sahara, in North Africa, and is about 3,500,000 square miles. Deserts are characterized by extreme heat and dryness, very hot in the daytime and chilly or even cold at night. The average temperature is 100 degrees during the day and below 50 degrees at night. The wettest desert does not get more than 10 inches of rain a year. A variety of plant and animal species live there, thanks to their power to adapt to the harsh environment. Animals like rattlesnakes and scorpions spend most of the day underground but come out at night to eat and hunt. Spade foot toads spend 9 months of the year underground. Deserts often get their names like "Death Valley" or "The place from where there is no return" because of their extreme conditions.

Chaparral Biome The chaparral biome is one that is found in areas of every single continent. However, many people don’t realize it is the same. That is because there are several different types of terrain that this particular biome is associated with. In some areas they are flat plains but in other regions there are hills. A chaparral biome is created when cool water from an ocean merges with a landmass that is at a high temperature. With a chaparral biome you will find that there is a very wet winter and also a very dry summer. These fires are usually the result of lightning striking in the area. The fact that many homes have been built on the edges of these biomes such as in California, it can be a huge threat when such fires break out. What is interesting is that many of the plants found in the chaparral biome have leaves that are made from highly flammable materials. The temperatures in the chaparral biome is about 30 degrees in the winter time. Chaparral Biome Facts and Information

American Desert Biomes - Desert Environments - World Desert Biomes Deserts cover more than one fifth of the Earth's land, and they are found on every continent. Deserts can be classified as "hot" or "cold". Deserts receive less than 10 inches of precipitation a year. Lack of water creates a survival problem for all desert organisms, animals, plants and people. What is a desert?

Facts About Buffalo Grass Buffalo grass (Bouteloua dactyloides) was a primary food source for the large herds of bison roaming the plains in years past, hence the name. It is today used primarily for cattle and other livestock on ranches in its native region. Lawns of buffalo grass consist of both male and female plants when established naturally. Male plants have taller crowns and long seed stalks, while the female plants provide a more uniform, dense lawn. Lawn grass seeds of the buffalo grass variety selectively consist of female seeds. History A grass found across the plains states, buffalo grass grows from Mexico to Montana. Environment Buchloe dactyloides, its scientific name, is extremely tolerant of hot, dry climates. Establishment Seed germination rate is good to excellent. Maintenance Buffalo grass requires little maintenance.

Grass - Temperate Grasslands *This specific type of grass was chosen because it is most abundant in Temperate Grasslands. Sure it isn't an "animal", but I think that it is important to note the most important part of the Temperate Grasslands. Linnean Classification: Domain: Eukarya Kingdom: Plantae Division: Angiosperms Class: Monocots Order: Poales Family: Poaceae Genus: Bouteloua Species: Bouteloua Dactyloides Conformer/Regulator This is a really great question. Dormancy/Migration Obviously, this depends on who you are asking. Generalist/Specialist Buffalo grass are generalists as they can thrive in a variety of climates and environment, such as the Great Plains. Niche Buffalo grass live in the most grasslands all over the world, feeding mainly on sun light as they are producers, making energy through photosynthesis, using it through cellular respiration. Producer/Consumer This also depends on who you ask. Type of Diet

Grassland Animal Adaptations Even though it is not very lengthy as such, the list of grassland animals does boast of some diversity - with animals found in this biome ranging from tiny insects and reptiles to some of the large mammals on the planet. Grasslands are home to the largest animal on land - the African elephant, the largest ruminating animal on the planet - giraffe, one of the most ferocious animals on the planet - the hippopotamus..., the elegant lions..., the swift black mamba... and so on. Each of these animals have adapted themselves to the conditions prevailing in this biome, and that explains why a significant portion of kingdom Animalia can be traced to these grasslands - which cover 25 percent of the planet's surface area. Grassland Biome Facts The grassland biome, which is typically characterized by the presence of different types of grass and herbaceous plants, covers approximately 25 per cent of the total surface area of the planet.

Best wishes, The Oracle Education Foundation Animal Adaptations for Temperate Grasslands There are several survival techniques used by different grassland animals. The one commonality on the plains is that there is some form of communication to alert others of danger. Often, when an animal senses danger it alerts the rest of the community by using a stamping or noise-producing technique. The sounds alert all of the animals of that species of an approaching danger. Smaller mammals will respond to an alert by heading to their burrows or other hiding places, such as under rocks, roots or other protective areas that a predator cannot enter. Larger mammals have a different technique that is critical to their survival.
