Chinese tallow tree also called chicken tree in southwest Louisiana is the most serious pest in Cajun Prairie and the Coastal Prairie Ecosystem. The seeds germinate quickly and the seeds are apparently spread by birds and thus move rapidly across the region creating dense thickets of this invasive species. Duralde Prairie is a 334 acre restored Cajun Prairie in Evangeline Parish, Louisiana and is a part of the Lacassine National Wildlife Refuge. The Cajun Prairie plants that have been restored on the site are responding and the area is moving toward restoration. But, there are patches of Chinese tallow trees scattered across the area, especially along the drains and in other wet areas. During the growing season of 2009, volunteers from the Cajun Prairie Habitat Preservation Society with the assistance of the Friends of the Southwest Louisiana National Wildlife Complex and Wetlands (Friends) will apply herbicide to the tallow trees. Smaller tallow trees will be mechanically removed. Each area that is herbicided will be gpsed and marked in the field. Follow-up monitoring will be performed by volunteers from the Cajun Prairie Habitat Preservation Society and the Friends group. The herbicides will be applied during June-August, 2009, 2010, and 2011 and the follow-up monitoring will occur in September-October 2009, 2010, and 2011.

Volunteers applied herbicides to invasive species and manually removed plants during July 24-25 and September 6-7, 2009, April 2 and June 8-9, 2010, and june 18-19, 2011. Volunteers also recorded data on acres treated, amount of herbicide applied, and locations.

How useful was this program for meeting refuge invasive species objectives and how can it be improved?
Clearcast herbicide treated Chinese tallow trees and had 90-100% mortality. Both Roundup and Element 4 treated Chinese privet and Element 4 worked the best with 80-90% mortality. Element 4 treated Japanese honeysuckle and had 80-90% mortality.
