MONITORING PHENOLOGY OF A THREATENED PLANT TO DETERMINE SEASONAL TIMING OF PRESCRIBED FIRE

At sites in Minnesota where the western prairie fringed orchid (WPFO) occurs managers face the challenge of timing burns to avoid damaging WPFO flowers while also controlling invasive smooth brome. This study used data collected by citizen scientists to track flowering of WPFO and development of smooth brome to determine the seasonal timing of prescribed fires.

Implications for managers:

• Data on timing of plant development can be used to plan management activities
• Fall prescribed fires may be effective at controlling smooth brome, and have less negative impact on western prairie fringe orchid
• Citizen scientists can collect meaningful data to inform management decisions
