[MAIPC] lesser celandine control??New EDRR species in the Mid-Atlantic

[Emily Grafton]

Greetings.
  We had a plant walk at the Ohio River Islands NWR Visitors Center and
discovered a huge population of lesser celandine in the flood plain of the
Ohio River.  It may have dispersed onto the islands as well.
  Does Carol recommend flaming it?  It certainly is low.  Most of the
patches have not flowered - yet.
