Future Webinars: Improving Wetland Restoration Success Project
The Association of State Wetland Managers is busy working on confirmation of webinar topics and presenters for 2016. Below you will find a draft list of future webinars to give you an idea of what we’re working on. Topics and dates are subject to change.
Tuesday, July 12, 2016 - 3:00 p.m. ET
Restoring Bottomland Hardwood Forests – John A. Stanturf, PhD, U.S. Forest Service
Bottomland hardwood forests (BLH) occur in the floodplains of major and minor rivers and reach their greatest extent in the southern US, in particular the Lower Mississippi Alluvial Valley. These species rich forests have been extensively cleared for agriculture and the rivers altered for flood control and navigation. Nevertheless, federal, state and private programs are attempting to restore BLH, mostly on economically marginal agricultural land. Matching species to site, primarily in terms of inundation regime and flooding tolerance, is a critical performance factor but often difficult to accomplish in altered landscapes. The challenges of obtaining quality seedlings and insuring an adequate planting job have resulted in outright failures or sub-par results. Adequate competition control may be constrained by limitations placed by federal cost-sharing programs. Attempts to restore microtopography and hydrological re-connection can be costly, produce adverse off-site impacts, or both. The presentation focuses on best available science and current practice in bottomland hardwood restoration.
Bottomland Hardwood Forests: Managing the Middle Years – John W. Groninger, PhD, Southern Illinois University
Agency land managers in the Cache River Wetlands of southern Illinois are faced with maintaining the full range of habitat conditions for diverse wildlife species. Following a period of intense afforestation concluding approximately 15 years ago, the Cache has been subjected to several significant stand and landscape level forces having long-term implications for restoration performance. Forest stand dynamics, historic disturbance patterns, invasive species and the use of indicator species for landscape level management will be highlighted. The presentation focuses on afforested stands now between establishment and maturity but also addresses management options for other important habitat components.
John Stanturf is a Senior Scientist with the US Forest Service in Athens, GA. From 1992 to 2000, he was Project Leader at the Center for Bottomland Hardwoods Research in Stoneville, MS where he and colleagues established a long-term study at the Sharkey Restoration Site. They compared two standard WRP techniques for restoring bottomland hardwoods (planting and direct seeding Nuttall oak) with a passive and a more intensive technique (Eastern cottonwood nurse crop with interplanted Nuttall oak). In his current position he retains an interest in bottomland hardwood silviculture and restoration while focusing globally on forest landscape restoration to meet the Bonn Challenge/New York Declaration to restore 350 million ha of deforested and degraded land by 2 030.
John Groninger is a professor in the Department of Forestry at Southern Illinois University where his teaching and research interests have include silviculture, agroforestry, urban forestry, and watershed rehabilitation in highly disturbed and socially unstable environments. Since coming to SIU in 1997, he and his graduate students have maintained a strong interest in regeneration and stand development within the Cache River Wetlands. This work is part of a broadly interdisciplinary effort among SIU researchers to address the full range of conservation management challenges within agriculture dominated watersheds. Prior to his present position, John was a Ph.D. student and Post-doctoral researcher and instructor at Virginia Tech
