Book excerpt: Terrestrial carbon sequestration is one of several proposed strategies to reduce the rate of carbon dioxide (CO2) accumulation in the atmosphere, but the impact of plant invasion on soil organic carbon (SOC) storage is unclear. The results of past studies are often confounded by differences in vegetation and environmental conditions. Reed canary grass (Phalaris arundinacea) is an herbaceous species that invades riparian fringes and wetlands throughout North America, including Beanblossom Bottoms - a wetland complex in south-central Indiana. Because of the prolific growth of P. arundinacea, it was hypothesized that significant alterations in SOC pools and dynamics would occur at invaded sites within the wetland complex. To test this hypothesis, study plots were established in areas colonized either by native herbaceous species or by P. arundinacea. Above and below-ground biomass were collected at the middle and end of the growing season and were analyzed for cellulose, lignin, acid detergent fiber, total phenolics, and organic carbon and nitrogen concentration. Soil samples were analyzed for SOC and nitrogen, bulk density, pH, and texture. The biomass of Scirpus cyperinus - a native wetland species was found to contain significantly (P

This book was released on 2018 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: We sought to determine the effects of 13 years of hydrologic management on the wetland plant community in Smith and Bybee Wetlands Natural Area (SBW), an 809 ha palustrine wetland complex in north Portland, Oregon. Previous management efforts resulted in an altered hydrologic regime; historically high water levels in spring and low water levels in fall were replaced by persistent water levels with minimal annual variations. A water control structure was installed in 2003 to better approximate historic seasonal hydrologic changes to reduce invasive Phalaris arundinacea (reed canarygrass) cover and promote native wetland vegetation growth. Vegetation monitoring has been carried out in three phases since project initiation (2003-2004, 2008-2009, and 2015-2016) to assess restoration efforts. Using lineintercept and differential leveling methods, we measured 25 randomly established transects ranging from 21.5m to 280.7m (mean: 92.87m) during monitoring years for vegetation and elevation to determine changes in vegetation in relation to seasonally varying water levels. Overall, reed canarygrass percent cover has decreased from 46.5% in 2003 to 17.6% in 2016 across all transect elevations. Reed canarygrass has been replaced significantly by seven native plant species with ≥ 5% cover on site. Native Persicaria amphibia (smartweed) has replaced reed canarygrass as the dominant species on site, increasing in cover from 20.2% in 2003 to 67.9% in 2016. Smartweed also replaced all other common species on site except for Salix lucida lasiandra. Other common native species (Bidens cernua, Eragrostis hypnoides, Eleocharis palustris, and Cyperus sp.) experienced earlier declines in cover between 2003 and 2009, but have since increased in cover primarily in low transect elevations in relation to lower inundation rates during their early growing seasons. Species diversity has declined significantly since 2003. Diversity was inversly correlated with reed canarygrass presence in 2003. These findings demonstrate that hydrologic management of a wetland system can be effective at reducing the presence of reed canarygrass and increasing native wetland vegetation by recreating historic hydrologic conditions that include increased inundation during the early growing season of reed canarygrass. Initial long inundation periods were most effective at reducing reed canarygrass, but did not need to be maintained indefinitely. Shortening and varying the inundation periods in later years after reed canarygrass has been reduced can be effective at maintaining lower levels of reed canarygrass while simultaneously increasing native species cover.

Available in PDF, EPUB and Kindle. Book excerpt: Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

This book was released on with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Herbivory plays an important role in plant community structure in many ecosystems through preferential selection, plant regrowth, and seed transport. Phalaris arundinacea, reed canary grass, is a prevalent wetland invasive species consumed by geese, muskrats, and snails. We lack a clear understanding of how herbivory impacts P. arundinacea's invasion potential. Therefore, I sought to understand the effect of herbivory by generalist macrograzers and micrograzers on the competitive dominance of P. arundinacea in created wetlands, especially the degree to which herbivory alters the competitive relationship between P. arundinacea and Typha latifolia (broadleaf cattail). To address this enclosure/exclosure cages were constructed in June 2013. Half of the plots contained only P. arundinacea and half were placed along the edge between P. arundinacea and T. latifolia. In caged treatments, amber snails (Succinea putris) were either included or removed. Control plots without cages assessed the effect of larger grazers. I predicted that herbivory would negatively impact the growth of P. arundinacea, and mixed plots would allow T. latifolia to spread into the P. arundinacea zone. Choice experiments were conducted with Branta canadensis, Canada geese, and S. putris to evaluate their preference for P. arundinacea or T. latifolia. I did not find any significant differences in P. arundinacea growth due to grazing but competition with T. latifolia did impact P. arundinacea. Edge plots at RIT had a significantly reduced growth rate compared to stems from plots containing P. arundinacea only. In choice experiments, geese showed a preference for P. arundinacea over Typha, whereas snails showed no preference. Despite the observed preference, I was unable to demonstrate effects of herbivory in the field. Herbivory appears to play a minor role in P. arundinacea's success as an invasive plant in created wetlands, with other factors, such as competition for light and nutrients of potentially greater importance."--Abstract.
