The invasive phenotype of Phragmites australis (Cav.) Trin. Ex Steud. continues to spread and invade new areas, having numerous and diverse deleterious effects on extensive areas of Great Lakes shorelines, coastal marsh habitats, inland wetlands and even transportation/transmission corridors used as vectors of invasion. Management approaches by natural area land managers vary dramatically, depending site size and many factors. There may be ongoing treatment on specific sites. There may be treated areas with uncoordinated follow-up on efficacy. Other sites - high priority sites - may be intensely surveyed for biotic response. In a recent survey of land managers, they have reported spending more than $80 million on management of Phragmites in a five-year period (Martin 2011) while no data have been published justifying the effectiveness of the management efforts to restore these native ecosystems (Hazelton et al. 2013). In this presentation, a representative from a cross-disciplinary team of natural resource professionals will share insights on new technology, field management techniques and ecological responses on ecological restoration sites. Based on years of experience and data collection, the presentation will feature methods and results of restoration-centered adaptive management (prioritization, logistics, treatment and monitoring) on Phragmites infestations. Also to be discussed will be new aerial imaging technology and remote sensing approaches that are contributing to efficiencies of Phragmites monitoring in Lake Michigan's Green Bay, Lake Huron's Saginaw Bay, and elsewhere, with significant agency, academic and NGO collaboration.

Jason Carlson has 15 years of professional experience with AES working with geospatial systems, aerial imaging, and mapping as applied to issues such as ecological restoration, watershed planning, and assessment of ecological impacts. As Director of the Geospatial Group and active project manager, Jason is involved in all phases of project design and technical oversight including GIS analysis, aerial imaging, database creation/management, and cartographic and GIS/GPS mapping/analysis techniques. In these projects, AES utilizes a Leica RCD30 multi-spectral camera, ESRI's ArcGIS, ERDAS Image, eCognition, and Trimble/Garmin GPS as well as other technologies. AES is pioneering the use of airborne imaging sensors for applied ecological efforts such as mapping distribution of invasive species over large geographic areas. Jason currently coordinates the aerial image acquisition flight crews for AES.
