[MAIPC] MAIPC Digest, Vol 58, Issue 13 -fire burns native plants with toxic fumes

Thu Aug 11 06:16:49 PDT 2016

There are three native plants in bloom and soon to be Poison Ivy - Toxicodendron Radicans that are toxic when burned - the toxic fumes are wind carried and cause hospitalizations to humans, do not know about other mammals just yet.  Maybe, now would not be the  time (the growing season) for burning?

Has anyone seen a response from either forest fire or prescribed fire on basketgrass? I?m curious how it responds to fire.
I would assume a low intensity fire this time of year (before seed) could control it.

Thanks

Hello Marc,
Here is a brief summary of what MNCPPC Montgomery Parks is doing:
--To date, MNCPPC Montgomery Parks has found WLBG in 11 parks, totaling 93 acres.
--It is typically found in dense forest interior with good leaf litter, or in streams or on stream banks.
--We?ve been able to chemically treat 21 acres, and mechanically treat 8 acres. The removal methods we are employing include chemical for dense blankets, and hand pulling for spot treatments. The hand pulling does seem to be effective if all of the roots are pulled up, which is easily accomplished since the rhizomes network through the leaf litter.
--We are currently in the phases of testing flame weeding these plants (applying extreme heat to stress and wilt the plants), and the preliminary results are promising.
--We hire contractors for chemical management, and use Staff led volunteer projects and a good deal of Weed Warrior volunteer time to mechanically remove it.
--All known occurrences are tracked on a GIS layer.

Unfortunately WLBG has been found in a number of Fairfax County Parks, including two natural area preserves. Volunteers are handpulling and contractors are spraying but it keeps popping up in different locations.

Subject: [MAIPC] Wavyleaf Basketgrass updates

I will present updates on wavyleaf basketgrass, Oplismenus undulatifolius, on September 17, 2016,  at the fall conference of the Maryland Native Plant Society. Please send me updates, both good and bad. For example, Ranger Mike Ellis with M-NCPPC, has found many new major infestations in Prince Georges County, MD. He and I have found it abundant in upland open space habitat provided a large amount of water is available.

1Funding for this project was provided by NASA's DEVELOP Internship Program and NASA's High-End Computing Program, the Middle Patuxent Environmental Foundation, the NSF Research Experience for Teachers (RET) program, the Baltimore Excellence in STEM Teaching (BEST) Project at Towson University, the Fisher College of Science and Mathematics and the National Fish and Wildlife Foundation's Pulling Together Initiative.
2Information on Oplismenus taxonomy was clarified through conversations with Mary Barkworth and Paul Peterson. We also thank our colleagues in NASA's DEVELOP Internship Program: Rachel Moore, Josh Henki, Stephanie Bates, and Ron Albright provided important contributions in the early stages of the project. We thank Roger Gill for his technical support in preparing data for the MaxEnt runs and field assistants Eric Cullings, Dana Wilson, Cody Kepner, Ken Compher, and Francis Smith for countless hours spent crawling through Oplismenus. Research facilitation and support from Robin Melton, past manager at Patapsco Valley State Park, was instrumental in the success of this project.

Abstract
A critical aspect of early-stage invasive species management is determining the niche and assessing the impact of a new species. A multi-scale strategy to predict potential habitat and impacts at the ecosystem, community and species level presents a robust, efficient, and cost effective tool for invasive species management. Regional scale maximum entropy modeling and local scale field studies were used to characterize species-environment and species-species interactions of Oplismenus undulatifolius, a recent invader in Mid-Atlantic forest understories. Oplismenus undulatifolius was first discovered in the U.S. near Baltimore, Maryland in 1996 and is currently found in 13 counties in Maryland and Virginia. At the landscape scale the USDA estimates that 30 percent of the U.S. is suitable for the establishment of O. undulatifolius. Regional scale modeling indicated that 22% of the area modeled was suitable for O. undulatifolius, with 1% highly suitable. Local scale field studies
  indicated that O. undulatifolius thrives at low light levels (2?11 mols m?2 day?1) across a wide range of litter depths (0?6 cm) and that light and litter depth are involved in dominance of O. undulatifolius over Microstegium vimineum. Interactions with Fagus grandifolia result in decreased O. undulatifolius cover and dominance, and areas of high O. undulatifolius cover typically have low species richness. Oplismenus undulatifolius has the ability to invade a far greater portion of the forest than M. vimineum, and more research on the community and ecosystem-level effects of this new invasive forest understory species is needed.
