"Effect of Burn Timing on Insect Assemblages in a Recent Prairie 
Reconstruction."
Anna Abney - Graduate Student Tallgrass Prairie Center

Prescribed burning is a common management practice in prairie 
reconstructions, but many entomologists are concerned about the impact 
of burning on insect populations. The effect of fire on insects has been 
studied on remnant prairies, but little research has been done on 
reconstructed prairies, especially the first years after planting. This 
study examines how spring and fall prescribed burns affect the abundance 
and community composition of grasshoppers (Acrididae) and ground beetles 
(Carabidae) in a recent prairie planting.
