Types

• Different types of grasslands, such as prairies, savannahs, rangelands, agricultural grasslands, and coastal grasslands, serve a variety of purposes.
  
  

Features

• "Rangelands are complex ecosystems," states the U.S. Geological Survey (USGS). Healthy rangelands "capture, store, and safely release water from rainfall, run-on, and snowmelt," according to the USGS.
  
  

Biotic Functions of Grasslands

• According to the Grasslands Conservation Council of British Columbia, grasslands function as a habitat for biotic components or living organisms "classified as producers, consumers or decomposers." For example, trees and plants produce nutrients through the process of photosynthesis, whereas consumers such as animals eat plants and other animals to get energy.
  
  

Function of Rangeland Grasslands

• Grasslands composed of grasses, such as wheat, provide grazing for livestock, as well as insect herbivores such as grasshoppers, locusts, and Mormon crickets.
  
  

Grasslands Provide Food

• "Grasslands have been the seedbeds for the ancestors of major cereal crops, including wheat, rice, rye, barley, sorghum, and millet," states the World Resources Institute (WRI).
  
  

Grasslands Are Breeding Areas

• Twenty-three Endemic Bird Areas include grasslands, which are important breeding grounds for thousands of bird species. The Andes in Peru, Central Chile, and southern Patagonia "rank highest for biological importance," states the WRI.
