cool, moist weather and/or with a change in photoperiod in the 

 early fall. 



The results of these studies may explain why seedlings of 

 Spalding's catchfly have never been detected in the permanent 

 monitoring transects on Wild Horse Island and at Dancing Prairie 

 when they have been read in late July or early August. Young 

 plants may spend the summer months hidden underground. These 

 results also suggest that if fire is to be used as a management 

 tool, burning during the summer months would have the least 

 impact on seedlings of Spalding's catchfly.
