Wilderness ecosystems

The wilderness ecosystem is the ecosystem that has been left undisturbed by humans. There are many areas on the planet that are considered wilderness such as the Great Barrier Reef, the Amazon forest, etc. They are rich in both flora and fauna diversity.

In the United States, a total of 42× 10^{4} ha is under the protection of the National Wilderness Prevention System. They are the lands devoted to the protection of the natural ecosystem. Such an arrangement had to be made due to human encroachment and various other factors that affect the wilderness ecosystem. The main threats to the wilderness ecosystem are

  • Using the land for recreational uses
  • Grazing by livestock
  • Forest fire
  • Pollution
  • Global warming
  • Invasion of alien species
  • The unnatural flow of water due to diversions, dams, impoundments, etc.
