What is a PRAIRIE?

A prairie is a close-to-treeless grassland with native plants found in North America. Grasslands with native vegetation on other continents go by other names (steppe, pampas, veldt). The 'sea of grass' and endless horizon associated with prairies by pioneers is no longer found in Illinois. Some large prairies still exist in Kansas, Nebraska and Oklahoma. Prairies are rare in the 'Prairie State'. Most Illinois prairies were destroyed by the plow, but even those that were not rarely maintain presettlement plant communities because the suppression of fire has resulted in encroachment by woody plants. Treeless areas that are not dominated by native prairie plants are more appropriately called old fields. Click here to know more about prairies.

The James Woodworth Prairie Preserve Mission

Our mission is to maintain populations of native prairie plants and invertebrate animals with abundances as close as possible to those prior to agriculture, so researchers and interested citizens have a place to study and enjoy what pre-settlement prairie was like.

Research has been done on:

  • The role of animals in building soil
  • Reverse fertilization to reduce the impact of atmospheric nitrogen deposition
  • The reason remnant prairies are so much shorter than restorations
  • Population dynamics of the prairie cicada

Management activities focus on: 

  • Processes (fire and water)
  • The elimination of non-native species
  • Enhancing abundance of autocthonous species with small population sizes
  • Controlling overabundant native species

James Woodworth Prairie (JWP) also plays a role in educating citizens about Illinois prairie.
