Desert Patagonian desert

Climate of the Desert in Argentina

  • Average rainfall: Northern Zone: 3.5- 17 inches , Southern Zone: 5-19 inches
  • Average Temperatures: Northern Zone: Maximum- 113 degrees F, Minimum- 12 degrees F, Southern Zone: Maximum- 93 degrees F, Minimum- 16 degrees F
  • The Patagonian desert is full of dry, cold,winds that come from the Pacific Ocean. The Northern Zone has generally a higher temperature but they both are normally around 50 degrees F. The southern Region receives more sunshine and has less humidity. The desert as a whole has extremely cold winters and very hot summers. Deserts are normally warm throughout the spring and fall, extremely hot in the summer, and winters have nearly no rainfall. This shows that they have a total of four seasons. They are all warm and fairly dry.

Net Primary Productivity

The Desert biome is normal found at a latitude of 30 North or South because this is where the warmth of the equator changes to dry air. The desert biome along with the tundra biome covers 33% of the Earth's surface. It along with the polar tundra receives the least amount of rain with an average of 10 inches a year while the tropical rainforest has nearly 60 inches per year. The net productivity is barely over 200 kilocalories per square meters per year. This is extremely low and the closest biome to being this low is the polar tundra which has 600 kilocalories per square meter per year. The desert only has one kilocalorie per square meter per day while the rainforest receives 25 kilocalories per square foot per year. This biome is not very diverse because only a few animals and plants are able to withstand these extreme conditions. The polar tundra and desert are barren, dry, and sandy regions. Normally only shrubs and small trees can endure these conditions. Animals often cannot live in these areas. Small rodents and reptiles are the most common animals in the hot humid desert biomes.

Soil Quality

Desert's soil is extremely fertile. This means that if they are given water they can grow a lot of food. Having said that, there normally is not many crops that grow because the desert region receives very little water. most desert soils are called Aridisols which means dry soil. Desert soil is more fertile than most soils because it only needs water to thrive.

Invasive and Endangered

Invasive South American Grey Fox

Purpose or accident? This mammal was introduced in the south american desert in 1951 on purpose in an attempt to regulate the rabbit population. They are all over South American.

Endangered Huemul Deer

This animal is endangered because of overhunting (Overharvesting in HIPPCO) and habitat destruction. People have converted the lowland habitats into agricultural advancements (H in HIPPCO-habitat destruction). There is only around 2000 huemul deers left on Earth.

Animals in the Patagonian Desert

The burrowing owl is is a sandy colored bird that lives in the desert. They are able to live here because their sandy coat allows them to blend and they live in holes that other native animals have dug up and forgotten about. They hunt mainly insects and rodents which there are plenty of in the Patagonian Desert.

The desert iguana is not only living but thriving in the desert. These creatures require open areas with a great deal of sand and heat. They can easily blend and stay hidden in this habitat and are capable of being active in intense heats. The iguana also are great rock climbers which allows them to easily hide from predators or simple find shelter..

The guanaco is able to live in the dirt because of how it was created. Their thick eyelashes protect their eyes from the dirt that is blown across the windy desert. They also have padded feet that allow movement along dry areas and rocks.

Plants in the Patagonian Desert

The Palo Amarillo lives and thrives in the Patagonian Desert. This is because it prefers humidity and high heat. it can also withstand long periods of drought.

The peppertree is native to the Patagonian Desert. it thrives the lowlands because it needs full sun exposer and can withstand drought.

The Mate Negre plant is another native pant to this region. It thrives because it has unusual leaves that can store large amounts of moisture closer to its branches.
