Grassland Praries By Jack Walt, Matthew, Lucas and Emma
This is a map of the world. The yellow stuff is the grassland
Where grassland Prairies are found They are found in every continent but Antarctica. It is not in Antarctica because it is to cold. They are found in warmer areas with lots of crops.
Physical Landscape Grasslands are vast areas covered with grasses and small leafy plants. The grassland seems like an ocean of grass. The soil of the grasslands is deep and dark.
Humans Influencing We maintain it by setting fires. We farm it. Wheat and a few other grains grow well in grasslands. We hunt on it. We shoot, kill, and eat such grassland animals as bison, quail, pheasant, and grouse. We keep livestock on it. Some breeds of cattle and horse can graze on grasslands.

Types of Grasslands Grasslands are all over the world They exist where there is not enough water to allow forests but enough water to allow grass plants to grow. Climate, plants and animals depend on the latitude and longitude and how close they are to the equator. and the closer they are to the equator the warmer it is. Different types of grasslands Prairies-North America Pampas-South America Africa-Savanna and Veldt Europe and Asia- Steppes
Precipitation Pampas inches per year Prairie -approximately inches per year inches in the shortgrass prairie to 21.7 inches in the tallgrass prairies. Savanna-average during the year is 20 to 40 inches. Dry season 4 inches, Wet season inches. Steppes-10 to 20 inches of rain each year.
Sunshine and Daylight Totals The Astronomical Department of the US Naval Observatory tracks the sunlight amounts in places all over the world. Pampas-12.2 hours of daylight Prairie-12.1 hours of daylight Savanna hours of daylight Steppes-12.2 hours of daylight
Humidity Pampas-very humid in the summer Prairies- more humid during the wet seasons and less humid during the dry seasons. Savannas-dry and humid with high temperatures Steppe- very little humidity in the air because it is located away from the ocean and near mountain barriers.
Temperature Summers are warm Average daily temperatures: −20 and 30 °C Winters are cold and sometimes have rain and snow. Pampas- The average temperature in the Pampas is 18° C. The climate in the pampas is humid and warm. Prairies-in January is 20° F, and 70° F in July. Savanna- Tropical temperature-very hot(104 ° F) Steppes-and wet season has very heavy thunderstorms. In the winter, temperature can get to -40° F.Cold and dry and very windy.
Wind Velocity Pampas- there are strong cold winds during the summer in the Argentina are called Pamperos. The wind blows most of the time. Prairies- the winds that come from Canada, called the Chinook, are warm and melt the snow in the winter in the western North American prairies. Savanna-The African Savannah has an avg. wind speed of less than 5miles per hour. It is known to be breezy. Steppes- There are no trees to block the wind, and it is very cold and dry.
Weather patterns throughout the Year Summers Pampas-in Argentina Summers are warm from late December through late March. The winters are mild, from late June to September. Prairies-hot Savanna- hot tropical Steppes-very hot Winters Pampas-mild Prairies-cold Savanna-warm Steppes-very cold
How Weather Patterns impact the Environment Pampas-there are four seasons and there are a lot of people that live in the Pampas of Argentina. Prairies-in the winter there are severe winter storms that can be dangerous to the environment. Savanna-In the summer, dry season the heat can make it difficult for animal survival. The grasses dry out. Steppes-Very cold and no trees to block the cold wind so it is a hard place to live. Animals dig holes to live away from the cold wind.
Types of Plants and Animals in Grasslands Plants Common types of plants Buffalo Grass Sunflower Asters Blazing Stars Coneflowers Goldenrods Clover Wild Indigos. Animals Common types of animals Coyotes Eagles Bobcats Gray Wolf Wild Turkey Canadian Geese Crickets Dung Beetle Bison Prairie Chicken
How Grasslands Impact the Environment Are flat land for easy survival and hunting for food of organisms Animals adapted to grasslands by digging burrows

Adaptions Some adaptions that things have made to stand the grassland prairies are in prairie dogs. Over the years, prairie dogs’ ears have grown closer to their heads. This is because they are burrowing creatures and they do not want to get dirt in their ears. Another adaption is animals in the grassland prairies is in other animals. There are not always safe living conditions for living, so animals have grown to be more camouflage. Lastly, the animals in the grassland prairies have adapted to the food availible. The diets of animals such as the coyote have developed to eating different rodents and other small animals.
Decomposers There are many decomposers in the grassland prairies. Some of them are worms. Worms in the grasslands’ job is to break down things in the soil and fertilize it. They make sure that the dirt is safe for other creatures to live in it. Also, they are food for the smaller creatures. Worms are an important part in the grassland prairies.
Abiotic and Biotic Abiotic and Biotic factors affect the animals in the grassland prairies. The abiotic factors that effect them are the temperature and precipitation. The temperature has caused some animals to burrow into the ground. The precipitation in the grassland prairies has caused some animals to grow coats that wick away water or be able to live in a lower humidity environment. Biotic factors that have effected the animals are the dead animals and the smaller living creatures. The dead creatures effect them because they become a fertilizing part of the soil. Living creatures effect each other thanks to the food chain. The bigger creatures eat the smaller ones and that effects everyone in the environment.

Conditions Grasslands have soils that are very rich because of the large amount of biomass that dies off every year. This is why grassland is often turned into farmland, which has been the case for most grassland in Ontario. Often grassland soil contains a large amount of clay, which retains moisture better than sandy soils so that plants growing there can put on a great deal of growth in the spring when there is more rain. Grasslands occur where there is less rain than many other ecosystems in the summer and fall.
Plant Species Big Bluestem(Andropogon gerardii) Broom Sedge(Andropogon virginicus) Kalm's Brome Grass(Bromus kalmii)
Plants Species Little Bluestem(Schizachyrium scoparius) Indian Grass(Sorghastrum nutans) Prairie Cord Grass(Spartina pectinata)
Plant Species Canada Wild Rye(Elymus canadensis) Scribner's Panic Grass(Panicum oligosanthes) Switchgrass(Panicum virgatum) Black Oatgrass(Stipa avenacea)
Special Adaptions There are some special adaptations that these plants have to make to live in the prairie grassland. It is very dry so they don’t get as much water as other plants. It is a very dry place and there is very little rain. If it does rain it rains a lot and the plant drowns or like I said before it dies from not enough rain.
