PROGRESS: Jan 1, 2009 TO Dec 31, 2009
OUTPUTS: The Ecology and Management of Invasive Plants Program continues development and implementation of biological control programs targeting purple loosestrife (Lythrum salicaria), garlic mustard (Alliaria petiolata), and common reed (Phragmites australis). For purple loosestrife we continue to provide tens of thousands of root feeding, leaf eating, and flower feeding insects to interested parties. We continued our long-term monitoring at select field sites in New York to assess success and replacement communities. Host specificity tests for the first insect species for garlic mustard control have been completed and a petition for release has been submitted to TAG. TAG has required a few additional test using additional plant species and these are now in progress. Evaluation of potential for biological control of common reed continues with a particular focus on the safety of the endemic North American subspecies of Phragmites. These biocontrol program developments are done in collaboration with scientists and managers from across the US and overseas (CABI Biosciences). A preliminary host plant list has been prepared, reviewed nationwide by botanists, ecologists and land managers and submitted to TAG. Recommendations by TAG are currently being evaluated. We continue our assessments of impacts of invasive plants on amphibian tadpole communities and we continue our evaluations of ecosystem impacts of invasive plants. We presented research findings at various conferences, including the Ecological Society, several state and the nationwide meetings and many local and regional workshops for land managers. PARTICIPANTS: Graduate students: Laura Martin, Jillian Cohen Collaborators: Richard Casagrande, Lisa Tewksbury, University of Rhode Island Patrick Haefliger, Hariet Hinz, Esther Gerber, CABI Bioscience Switzerland Victoria Nuzzo, Natural Areas Consultants Luke Skinner, Minnesota Department of Natural Resources Eric Nelson, Department of Plant Pathology, Cornell University Partner organizations include a multitude of land management organizations (state, federal, private). A short list includes: USFWS, NPS, DOT, The NAture Conservancy, State Wildlife or NAtural Resource Management Agencies TARGET AUDIENCES: Scientists, land managers and the interested public PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.
IMPACT: 2009-01-01 TO 2009-12-31
We have continued to provide assistance with biocontrol project implementation (release of insects for purple loosestrife) and new program development. From initial release sites insects have spread for many kilometers and widespread defoliations of purple loosestrife were reported from across the country. The completion of host specificity work and anticipation of field release of garlic mustard insects has created an intense interest in the land manager community across the US. At many locations managers have implemented our standardized monitoring protocol (available at inavsiveplants.net) to provide pre-release data. I have continued a free Diagnostic Service to help land manager identify native (in need of protection) and introduced (invasive and in need for control) genotypes of Phragmites australis. This service has protected many small native stands, which otherwise would have been sprayed. Our ongoing work on effects of changes in plant communities on amphibian and invertebrate communities has greatly raised the awareness of the potential severe impacts associated with encroachment of non-native plant species. These impacts materialize through direct toxicity and indirect through wholesale changes in food webs. However, these impacts are plant and species-specific and at present we cannot find a distinct effect that separates introduced plant species as a group from native plant species.
