Can Burning Benefit Insects in Isolated Prairies?

The lack of long term data looking at how invertebrates respond to prescribed fire led Ron Panzer to conduct a six year study spanning three states. Invertebrates were grouped by their dependence on remnant prairie sites and populations tracked through multiple burns to determine rates of recovery. 

Implications for Management:

• Annual fires may not allow a long enough recovery time for a minority subset of prairie insects
• Burning every 2-3 years may balance concerns over insect recovery with other conservation goals (e.g., plants, birds)
• Remnant dependent insects recover at the same rate as remnant independent insects
