Transcript of Grassland Biome

Grasslands Recreational Activities Attractions/ Tour Package The Average Temperature in the grassland biome is 20°C (68°F) to -5°C (23°F). Weather Report Threats! Warnings! Analysis/Evaluation Geographic and Species Information The grassland biome can be found in the western part of the U.S. It can also be found in southern Asia, eastern edge of South America, and very little in southern Africa. Biotic Factors Flowers such as Turk's Cap Lily are biotic factors. Animals such as a kangaroo are biotic factors also. Reptiles such as the Leopard Gecko are biotic factors. Abiotic Factors The temperature in grasslands is very hot. Sunlight is what keeps the grasslands hot and dry. There is very little rain in grasslands so, the animals must adapt to little water. Adaptions of Native Plants One of the native plants is Ragged Fringed Orchid. It has adapted because it is used to wet conditions. Another native plant is the Giant Sunflower. It has adapted to the little rain because it used to moist conditions. Ragged Fringed Orchid Giant Sunflower Zebras have adapted to grasslands by using the grasses and shrubs as food. Adaptation of Native Animals Lions have adapted to grasslands by using animals such as gazelles as prey. Ostriches have adapted by not being reliant on water, eating grass seeds, and having long legs to run fast from predators. Cooperation and Competition One example of cooperation is lions fighting together to take an ostrich to get a meal. Some examples of competition in grasslands are over food like bobcats for a prairie chicken. There is competition over territory like lions over living areas. There is also competition over watering holes and mates. Mutualism, Parasitism, and Commensalism An example of parasitism is a wolf being bit by ticks or fleas. In grasslands, an example of mutualism is the African Buffalo and the Oxpecker. The oxpecker will clean ticks and other annoying parasites off the buffalo's back. An example of commensalism in grasslands is a giraffe and a tree. The giraffe is getting food while the tree is neither harmed nor has benefited. Food Chain Food Web Bird Watching- Bring Binoculars! Find birds like the one and only Corncrake! Moth and Butterfly Spotting- Spot moths like the Hornet Clearwing. Animal Watch- Go on a tour and find animals in the grasslands. Don't forget your binoculars! Points of Interest Great Valley Grassland National Park, California Go on the Grasslands Trail to see the beauty of wildlife! See the San Joaquin River and the sweeping grasslands. Go on your very own picnic and see the beautiful view of the amazing grasslands. See plants, animals, and beautiful moths and butterflies. Biomes Nearby! Drive to the Shore! Go scuba diving off the shore in the oceans! Also, try out surfing if you are brave enough! Oceans! Desert! Drive down south and experience the hot, dry air of the deserts! What is the average temperature? What is the average precipitation? The Average Precipitation in the grassland biome per year is about 100cm. (40in.) What to Wear! Wear light clothes so you don't get to hot! You should wear t-shirts and tank tops. Also, wear shorts or capris to keep your legs cool. Wear tennis shoes or hiking boots for the walking. Bring a jacket just in case it gets cool and don't forget a ball cap! Gear! You should have a bag/backpack to bring carry your gear. Bring water, binoculars, insect repellent, matches, a snack, and extra clothes. If camping bring a tent, tarps, and extra sealed food so animal cannot get in it. Climate! There are many different types of grasslands but, two of them are Tropical and Temperate. Temperate- The temperate grassland has cold winters and hot summers. The weather is almost always changing making it hard t pack the right clothes Tropical-The climate is very hot and, there is a wet season. The summers are warm and the winters are humid and dry. About 18in. of rain per year. One major threat in savanna grasslands is poaching. Poachers will kill and take hide or in most cases tusks. They will kill elephants for there tusks made of ivory. Threats Continued... One other threat is that there are rapid urban and coal mining expansions. At an estimated 23% is how much habitat loss is caused by this. Endangered Animals! Asian Elephant
Black Rhinoceros
Grevy's Zebra
Rothschild Giraffe Asian Elephant Black Rhinoceros Grevy's Zebra Rothschild Giraffe Is there fear of climate change in grasslands? Grasslands are expected to take the place of many forests. Under the climate change, trees would have less water and be more dry making them more vulnerable to fires. That is why grasslands to expected to take the place of forests. Human Impact Humans destroy the grasslands to use them as fields. The farmers will start fires to burn the shrubs and tall grasses. We farm on the fields. Some fires are started to maintain the grasslands. We also hunt in the fields to get our meals. Most farmers even use the fields to keep the livestock in. Why is this biome globally important? Grasslands are important because livestock graze in the fields. This livestock provides us with meat and milk. We also hunt in the fields as other sources of food. Also, we pick the berries and other foods that we grow. The End! Any questions? Landforms and Bodies of Water! Landforms- There is no mountains just plains with a few rolling hills. Bodies of Water- There are rivers, lakes, ponds, swamps, bogs, sloughs, and creeks. Just like the ostrich, the prairie chicken feeds off of seeds and doesn't need much water. Goldenrod is another native plant. It has adapted to less water and lots of sun. Goldenrod
