Journal description

Wetlands is an international journal concerned with all aspects of wetlands biology, ecology, hydrology, water chemistry, soil and sediment characteristics, management, and laws and regulations. The journal is published quarterly, with the goal of centralizing the publication of pioneering wetlands work that is otherwise spread among a myriad of journals. Since wetlands research usually requires an interdisciplinary approach, the journal in not limited to specific disciplines but seeks manuscripts reporting research results from all relevant disciplines. Journal of The Society of Wetland Scientists.

    ABSTRACT: Comprehensive wetland inventories are an essential tool for wetland management, but developing and maintaining an inventory is expensive and technically challenging. Funding for these efforts has also been problematic. Here we describe a large-area application of a semi-automated process used to update a wetland inventory for east-central Minnesota. The original inventory for this area was the product of a labor-intensive, manual photo-interpretation process. The present application incorporated high resolution, multi-spectral imagery from multiple seasons; high resolution elevation data derived from lidar; satellite radar imagery; and other GIS data. Map production combined image segmentation and random forest classification along with aerial photo-interpretation. More than 1000 validation data points were acquired using both independent photo-interpretation as well as field reconnaissance. Overall accuracy for wetland identification was 90 % compared to field data and 93 % compared to photo-interpretation data. Overall accuracy for wetland type was 72 and 78 % compared to field and photo-interpretation data, respectively. By automating the most time consuming part of the image interpretations, initial delineation of boundaries and identification of broad wetland classes, we were able to allow the image interpreters to focus their efforts on the more difficult components, such as the assignment of detailed wetland classes and modifiers.

    ABSTRACT: Shifts in soil water content affect seasonal wetland plant communities worldwide, but little is known about the responses and influences of plant communities to soil water content on Qinghai-Tibetan Plateau. To determine the relationship between soil water content and plant community structure in seasonally wet alpine marshes, we investigated plant community structures at different soil water content amounts in the field station at sampling sites. We selected and determined eco-physiological characteristics of species belonging to three different functional types (sedges, grasses, forbs) exposed to the same soil water regimes as characteristics in field station and under experimental flooding conditions in controlled treatments on pots plants. The field investigation indicated that decreased soil moisture (from 57 to 43 % m3 m−3) during the growing season was significantly associated with reductions in aboveground biomass, average plant height, and species richness. A shift in dominant plant species within the communities from sedges and grasses to some forbs accompanied the decrease in soil moisture. The controlled treatments demonstrated that the sedge and grass species had higher net photosynthetic rates and higher instantaneous water-use efficiencies than the forb species in the studied communities. The results indicate that shifts in wetland plant community structure and function are the result of longer dry periods and more intense rainfall events. This positive feedback suggests that changes in plant community composition could intensify soil drought conditions in seasonally wet alpine marshes in the future.

    ABSTRACT: Rising sea levels and stronger storm surges may expose tidal freshwater wetlands to saline waters, possibly leading to increased sulfate reduction and higher sulfide (H2S) concentrations. To better understand the effects of salinity on nitrogen cycling, porewater chemistry and sediment profiles of H2S and dissolved oxygen (O2) were measured along a salinity gradient in the Hudson River (New York, USA). Additionally, laboratory experiments exposed freshwater sediments to varying salinities after which sediment O2 and H2S dynamics along with nitrification and denitrification were measured. Overall, sites with higher salinities had lower oxygen availability (both as concentration and oxic sediment depth) and higher sulfide concentrations. Both nitrification and denitrification were depressed at higher salinities suggesting that exposure to saline water may alter nitrogen cycling of tidally influenced wetlands in the brackish region of the Hudson River estuary which may result in reduced retention of nitrogen.

    ABSTRACT: A long-term data base (2000–2009) was used to evaluate tidal floodwater salinity and the resulting soil biogeochemical setting (methanogenic or sulfate reducing) at 54 substations, which included a variety of marsh and swamp community types along the freshwater/saltwater boundary of the Cape Fear River/Estuary, North Carolina. During this decade, a variety of extreme climatic events, i.e. floods and droughts, occurred, but overall data reflected long-term, natural conditions. At sites flooded by >1 ppt saline water more than 25 % of the time, wetlands consisted of varying types of tidal marsh. Temperate, tidal swamps were present at sites flooded by this level of saline water less than 12 % of high tides. Flooding >25 % of tides by >1 ppt seawater converted soils in those wetlands from methanogenic into sulfate reducing conditions >50 % of the time. The point along an estuarine gradient where adjacent wetlands are flooded by >1 ppt saline water less than 25 %, but more than 12 % is the zone of transition. The conversion of a tidal swamp to tidal marsh is not only caused by salt water itself, but by the sulfate constituent in seawater. Once a sufficient concentration of sulfate enters soils, sulfate reducing bacteria become active reducing the sulfate into hydrogen sulfide, which is toxic to any wetland plant species not adapted to this toxic substance. The incidence of flooding by high tides containing >1 ppt salinity is an accurate predictor of functional change in adjacent wetlands. Wetlands receiving intermediate levels of saline water, i.e. 12-25 % flooding with 1 ppt floodwater, were in some state of transition from swamp to marsh. Once trees in tidal swamps are killed, the wetland moves inevitably towards a tidal marsh dominated by species of herbaceous vascular plants with varying tolerance to saline water.

    ABSTRACT: Traditional water depth survey of waterbird habitats takes huge amount of labor, time and money. The optical remote sensing image from passive multispectral scanner has been widely employed to estimate water depth. We developed a water depth model based on the characteristics of visible and near infrared spectra of Landsat ETM+ image at Etoupao shallow wetland. The wetland is the largest stopover habitat of the critically-endangered Siberian Crane, which mainly feed on the tubers of Scirpus planiculmis and S. nipponicus. Water control is critical for maintaining tubers production and food availability for the crane. Multi-band approach is employed in the model, which effectively simulates water depth for the shallow wetland. The parameters of NDVI and GREEN in the model indicated that the vegetation growth and coverage affecting reflectance from water column change were uneven. Combined with observed water level data in the same day of image acquisition, the digital elevation model (DEM) for underwater terrain was generated. The findings provide a good reference to manage water level and water demand, and create suitable foraging habitats for the crane. The methods can be adapted for underwater terrain simulation and water management in waterbirds habitats, especially in the shallow heterogeneous wetlands.

    ABSTRACT: Anthropogenic land use has significantly altered sediment and nutrient dynamics at watershed-scales, resulting in significant redeposition within large floodplain ecosystems. Some upland land uses have had documented negative effects on soil carbon (C) stocks, although the specific impacts of these disturbances on soil organic carbon (SOC) dynamics in depositional environments are poorly understood. Assessment of SOC stocks in floodplain environments will allow for more precise estimates of C distribution at watershed and regional scales. In this study, we measured SOC pools to depths of 100 and 200 cm in four distinct floodplain landscapes (natural levee, flats, mineral wetlands, organic wetlands) in a large bottomland forest within Congaree National Park, South Carolina, USA. Mean SOC stocks to a depth of 100 cm were 108–109 Mg C ha−1 in flats and levees, 193 Mg C ha−1 in mineral wetlands, and 533 Mg C ha−1 in organic wetlands. In addition, hydric soils contained significantly more SOC in deep horizons (100–200 cm depths). At a regional scale, similar alluvial soils within large floodplains were estimated to store approximately 0.l Pg of SOC. These results highlight the importance of inclusion of deep SOC storage in alluvial settings when estimating watershed C budgets.

    ABSTRACT: Little is known how soil type may interact with fertilization in affecting carbon fluxes in wet grasslands, habitats of high conservation value which have decreased in area due to agricultural intensification. A nutrient (NPK) addition experiment, with three treatment levels in a block design, was established to compare nutrient effects on particular carbon fluxes (plant production and nutrient contents, and plant and soil respiration) in two wet grasslands in the Czech Republic, with either organic or mineral soil. Between-site and treatment differences were tested by one and twoway ANOVA; temporal changes by repeated measures ANOVA. We hypothesized that the organic site would be more sensitive to nutrient additions. Aboveground biomass and total dark CO2 emissions increased significantly with nutrient addition in the organic, but not the mineral, site, thus supporting our hypothesis. Hay removal and the short duration of fertilization (3 years) may account for the lack of other significant effects. Soil properties (bulk density, C:N ratio, microbial community structure) likely underlie these differences between the wet grasslands, although site hydrology and plant species composition may also be important. Soil type, as well as the other factors, must be considered when restoring or managing for well-functioning, resilient wet grasslands.
