SAVANNA OAK FOUNDATION: Hybrid Cattail Control at Pleasant Valley Conservancy SNA

Purpose

Savanna Oak Foundation, Inc. will work with its consultant Integrated Restoration LLC to remove existing hybrid cattail (Typha x glauca Godr.) stands in the Pleasant Valley Conservancy wetland complex. The current population covers less than 0.5 acres. The goal is to fully remove the species so it cannot spread and so that high quality native plants already established in the watershed can repopulate the cleared areas. Follow up treatments will occur in 2017, if necessary. Additional efforts in July 2017 are to identify, geo-reference, and eliminate any additional T. x glauca or T. angustifolia clones detected during vegetation surveys and to map all clones and culms of both aquatic invasive species with ArcView GIS for future monitoring. The results will be documented on the Pleasant Valley Conservancy website and Facebook page as well as made available to others requesting information.

Reports and Documents
Work has been finished for this project, which has included two seasons of control by cutting and chemical treatment of the hybrid cattail that invaded areas of our marsh at Pleasant Valley Conservancy. Our contractor, Integrated Restorations, and our own staff have worked on this project. The area involved included one large circular area and three other small areas which were discovered during our extensive surveys of the entire wetland. Included are copies of the APM permits (both mechanical and chemical) which were issued for both 2016 and 2017. Our own marsh comprises less than 30 acres, but is part of a large wetland covering approximately 140 acres, owned by 5 families. The cattails were noticed about 3 years ago, and grew extremely rapidly, doubling in diameter in a season. The largest clone measured approximately 100 ft in diameter when control started. At its rate of growth, it is estimated that if not properly treated, it could have overwhelmed most of the entire wetland eventually. During our work, we made surveys of the wetland, and found 3 other small clones and scattered stalks here and there, which were also cut and treated.
