Kern Introduced Species

In Kern County, we are surrounded by plants and animals that have been introduced by man. 

  • Did you know that this region was once a huge marsh surrounded by desert? 

  • Did you know that the golden hills of Kern County were once green year round with perennial grasses? 

  • Did you know that the rat and mouse that cause the most problems for man are from Europe- they hitchhiked on ships, stagecoaches, and railroads? 

  • Did you know that the bullfrog and carp were introduced to area waters and are causing the extinction of some native fish and amphibians?

  • Did you know there have been "Acclimatization Societies" that introduced such pests as the House Sparrow and European Starling?

  • Did you know that the Peppertree, Eucalyptus, and Salt Cedar as well as many other trees and bushes were introduced?
