Biologists are studying streams to prevent tallgrass prairies from turning into shrublands and forests. By looking at 25 years of data on the Konza Prairie Biological Station, they are researching grassland streams and the expansion of nearby woody vegetation, such as trees and shrubs. They have found that burn intervals may predict the rate of woody vegetation expansion along streams.
