Threats
The one major threat to grasslands is Global Warming.
It is neccessary for the climate of a grassland to stay in perfect harmony, within the boundries of the climates of the biomes around it. If the patterns of Earth are changing, then so will the areas where grasslands can exisit. This would mean an ecological succession in all major grassland areas.
Another Threat is industrilization and movements of the human population.
"Once numbering 90 million, the American bison now only survives in refuges and parks.' (Bison 1 )
"Before Europeans arrived in North America the bison population is estimated to have been 90 million. By 1890 it was only 1,000. They were culled for their meat, hides, and also to destroy the Native Americans' food supply." (Bison 11)

Maintaining A Prarie
This is one way humans make their impact, and control the environment.
In the United States, one way to control the 'spread' of grasslands is by setting controlled fires. (Missouri Botanical Garden)
These are two pictures from the Missouri Botanical Garden depicting the process of a contained wildfire.

Endangered Spieces
Few of the grassland animals are on or near the endangered list. They are being hunted by poutchers and their habitats are being destroyed by the furthering of the human environment.
In Aulstralia, over the last 200 years, more than 50% of the native mammals have gone extinct. This is due mainly to the human transgression and overtake of the wild savannah and the habitats of some many animals.
In Africa, and all over the world, many animals are going extinct and enterting the endangered list due to human interactions. In the past few decades this has been seen with the Black Rhinoceros, the Asian Elephant, the American Bison and the Quagga. One terrible threat is created by poaching. This is illegal and inhumaine. Another is 'intense persecution by humans as well as habitat destruction from overgrazing...' (Ostrich 12)

Did you know?
Baby Giraffes are called calfs, and they spend 15 months inside their mothers wombs before dropping to the grassland. (BBC 10)
About 50% of calfs die in their first 6 months of life in the hands of preditors. (BBC 10)
The average life-span is 25 years, and 28 in captivity. (BBC 3)
