Fire-Induced Mineralogical Changes In Midwest Tallgrass Prairie Soils, Lacey Legrand Mar 2018

Fire-Induced Mineralogical Changes In Midwest Tallgrass Prairie Soils, Lacey Legrand

UNO Student Research and Creative Activity Fair

Tallgrass prairies are productive ecosystems that historically covered a large part of the Midwest and in the past were subjected to frequent, natural fire regimes. Today prairie remnants are often managed by ecological burns. Glacier Creek Preserve is a restored prairie in Omaha, Nebraska that includes randomized research plots established in 1978 to study the effects of burning on vegetation and provides a controlled field environment to investigate the effects of fire on soils. The purpose of this study is to compare soil mineralogy in long-term burned and unburned plots to answer the question: “Does prescribed burning induce mineralogical changes …
