Hello! My name is Oliver the Owl and this

is my home, an old hole in the Argentina

Dry Pampas. Lets travel outside so I can

explain more about this wonderful

grassland to you.

As I said before, I live in the Argentina

Dry Pampas. The Dry Pampas are anexample of an ecosystem, a group of

both living organisms and nonliving

things interacting together.

The Dry Pampas ecosystem is an

example of a Temperate Grassland

biome. A biome is a grouping of

ecosystems where the climate, plants,

and animals are all similar.

As you can see, the Dry Pampas are not full of

big trees and woods. Unlike the Humid Pampas to the

East, it and other Temperate Grasslands do not receive

much rain. They are wetter than deserts but drier than

forests, so low grasses and shrubs thrive. savannas, often

confused with temperate grasslands, have taller grasses

and receive more water. Also, the temperature varies

wildly between the seasons.

The Dry Pampas are mostly all plains, and most

animals here either live on the grass or in burrows in the

ground like me. Although we dont get much rain here, therich soil helps to nourish the plants.

Our home is in danger. We have recovered from natural

disasters, but human activity is much more frightening.

Humans have created many farms and ranches on the land,destroying the habitats of my fellow animals! In fact,

Argentina has become the worlds third largest food producer.

Good plants called decreasers are killed by these humans,

and bad ones called increasers start to fill up the land along

with new plants called invaders!

When the humans farm, they use up all the rich minerals and

water. The amounts of important elements like Carbon,

Nitrogen, and Oxygen are dropping rapidly. We fear that

humans might even make the Dry Pampas a desert. Also, their

farming plays a big part in the dust storms, Pamperos, that I

told you about before.

But the effects that humans have on our ecosystem is much

larger. Human activity has resulted in something we call global

warming. They have made the area get hotter, and if it gets toohot, water will begin to leave faster. If water leaves faster, this

grassland will become a desert!

Or, more water may come down in the form of rain. If that

happens, trees will grow and the grassland will become a forest!

The big trees would block the little grasses and shrubs from

getting sunlight, and they could die.

But what does this mean? Remember that plants take in the

carbon dioxide we breathe out and make oxygen. If the plants

die, too much carbon dioxide, which contributes to global

warming, will be floating around and not enough oxygen.

If the grasslands lose too much water that they become a desert,plants will die and the same will happen!
