Do grasslands face ecological problems

Answer 1

Global warming is only one: clean water, water conservation, prevention of water contamination, and fire prevention are key issues. Also farming is one.

Even though the grasslands have rich soil if you farm on it and use machines or tractors to harvest and other things it would not be rich soil anymore. When the farmers use machines or tractors they will push down the rich soil and make it dry soil. And by doing that they will make the green grasslands into deserts.

Humans have cultivated many crops on grassland soil. The soil is rich and almost anything in it can grow if it is both used and treated right. Poor agriculture practices can ruin soil and turn a grassland into a lifeless, barren land. If crops are not rotated properly, all nutrients in the soil are stripped and poor soil results. The soil then turns to dust and nothing can grow in it for many years.

Cattle and livestock ranchers have also ruined grasslands. Many years ago, North America was covered with 250 million acres (101 million meters) of prairie grasslands. Today, because of over grazed land and over worked soil, only five percent of the original prairie remains. Over grazed grasslands in Australia and South America have caused native animals to compete for food.

Answer 2

One of the greatest threats to grassland ecosystems is the disappearance of that habitat type as the land is converted to monocrop agriculture. There are diverse plants that grow in grasslands and diverse animals that feed on them.

Another challenge facing grasslands is that periodic fire is needed to maintain them; this happens naturally and helps maintain the diversity of plants and animals. Controlled fire programs are one way to maintain grasslands and to prevent uncontrolled wildfires from threatening human lives and property.

Answer 3

The most ecologically troubling practice in the temperate grasslands is using it almost entirely for agriculture. Grasslands like the prairies of North America make excellent farm land due to high amounts of soil nutrients. For this reason, grasslands are converted into farm land and almost no natural temperate grassland remains today.

Answer 4

Small amounts, or too much, precipitation. To little can cause grass to die or dry out so animals cannot eat it. To much can cause floods.
