these sites would have to be reseeded to protect against 

 the invasion of other undesirable, weedy plants. Gly- 

 phosate treatments appeared to result in the best ini- 

 tial control among the herbicide treatments. Reseed- 

 ing might greatly improve the longevity and success 

 of this treatment. Considering herbicide application 

 without reseeding, the picloram treatment appears to 

 have had the best control over the full 9-year period 

 and the most favorable commimity response.
