Hi Jennifer,

Thanks for yet another wonderful good-news story! Thanks so much for treating this population of Old Man's Beard! Was this a project you did with your class? Removing the seeds was a great idea as to prevent further spread. Also in the spring we can confirm the ID since there is a native clematis, and we need to be sure it is not the native before removing the plant completely. However, based on your description of the population it sounds like you have the invasive species! Lets work together to figure out the best control this spring/summer.

Please keep on looking out for Clematis vitalba! Thanks so much for engaging your class in Early Detection and Rapid Response!
