• Fire
• Grazing
• Drought
Use of pesticides
Which of the following qualities determines if an area should be considered a grassland?
• Height of plants
• Amount of precipitation
• Location
• Amount of stored carbon in soil
Amount of precipitation
Some climate scientists even believe grasslands may be more efficient and reliable at removing carbon from the atmosphere than forests, because grasslands are more resilient after fires and drought.

Which of the following limits the biodiversity of grasslands?
• Loss of topsoil
• Pesticides and fertilizers
• Farming a single variation of a crop
• Grazing animals
Farming a single variation of a crop
Cattle may decimate vegetation through overgrazing and their heavy hooves compact soil leading to erosion and loss of sod.

• False
True
Which of the following services was formed by the federal government due to the Dust Bowl?

Which of the following agricultural practices ensures an area is NOT overgrazed by moving cattle from pasture to pasture?
• Continuous grazing
• Rotational grazing
• Set stocking
• Tactile grazing
Rotational grazing
Which of the following is NOT a reason why cover crops are important?
• Provides habitat for spiders to eat crop pests
• Provides shade to the main crops
• Increases water retention
• Prevents soil erosion
Provides shade to the main crops
Why is fire considered a common management practice?
• Fire burns and removes topsoil so more fertile soil will be available
• Teaches grazing animals to stay away from specific areas
• Fire is not a common management practice and should be avoided
• Suppresses invasive species such as shrubs and trees
Suppresses invasive species such as shrubs and trees
Grasslands typically exist between which of the following?

Select all the services grasslands provide.
• Build deep and rich soils
• Store carbon dioxide from the atmosphere
• Provide very important habitat for wildlife
• Filter runoff from precipitation
• Build deep and rich soils
• Store carbon dioxide from the atmosphere
• Provide very important habitat for wildlife
• Filter runoff from precipitation
Why do temperate grasslands have the most fertile soil on earth?
• Temperate grasslands receive the most rainfall compared to other grasslands
• Grass roots decaying below the surface enriches the soil with nutrients
• Trees require substantial amounts of nutrients to grow, so the lack of trees in grassland areas allows for more fertile soil
• Grasslands have the least number of invasive species who absorb nutrients from the soil
Grass roots decaying below the surface enriches the soil with nutrients
Where are savannas typically found?

• Higher altitudes
• South of the Tropic of Capricorn
• Europe and North America
Africa, Australia and South America

• Special tax farmers must pay each year which goes towards conservation
Incentives provided to landowners to conserve grassland habitats

Conservation Service?
• To conserve soils for agricultural production
• To improve water resources on grasslands
• To enforce the Farm Bill
• To keep grasslands in their condition and not allow trees and invasive species alter the land
