The summit includes both virtual presentations from experienced researchers and managers on August 12 and field tours to see infestations in-person and learn from professionals actively engaged in managing this species on August 13.  Four different field tours are available across the range of chaff flower plus a virtual tour option for those that cannot attend a field tour in person.

The summit is free and open to the public.
