“…Vegetation parameters in particular have yielded mixed results. While some studies report increased plant biomass or diversity (Erwin and Best, 1985;StaufFer and Brooks, 1997), others have reported no difference in plant growth in the first few years (Bailey et al, 2007;Sutton-Grier et al, 2009). This is significant as plant growth and diversity are commonly the variables used to determine success of wetland mitigation projects approved by the Army Corps of Engineers (Hoeltje and Cole, 2007).…”

The creation and restoration of wetlands is widely seen as a critical tool for replacing ecosystem functions lost by historic wetland destruction. However, studies have shown that these wetlands often take hundreds of years to achieve the functions for which they are restored. We used controlled field-scale manipulations in four recently restored depressional freshwater wetlands in western New York to investigate the impact of organic amendments of differing lability on tbe soil and vegetative development during the first 3 yr. Results showed that the addition of soil amendments to wetland plots stimulates development of key soil properties that are critical for wetland functioning. In particular, initial increases in soil C and decreases in bulk density in topsoil and biochar amended plots were still present 3 yr after restoration. Plant biomass recovered quickly and had reached levels of comparable natural wetlands witbin 2 yr, irrespective of amendments. Amendments did not influence plant diversity. Site differences, however, did influence plant diversity and different sites hosted different numbers and types of species. Two years after restoration, both desirable native wetland species and undesirable weedy species bad colonized eacb site. Results of tbis research reveal that organic amendments can improve key soil properties critical for wetland functioning. Tbe strengtb of treatment effects and the development of tbe plant community, however, are highly influenced by initial site conditions. These results confirm the importance of focusing on both hastening soil development via amendments and careful site selection in restoration design.Abbreviations: BD, bulk density; CEC, cation exchange capacity; SOM, soil organic matter.

Abstract.The frequent colonization of the margins of abandoned and unreclaimed wet sand and gravel pits by typical marsh vegetation indicates the feasibility of a created wetlands component in gravel/sand reclamation planning. Using the natural pit wetlands as models and examining the peninent literature, guidelines were developed for: (1) selecting promising sites, (2) planning with a regional perspective, and (3) construction and monitoring. Key concepts are: hydrological stability and adjacent land uses that will not have an adverse impact; consideration given to how a pit wetland will interact with adjacent ecosystems on a regional level; grading of pit perimeters to produce irregular contours and no more than a 0.6 m change of elevation within the proposed wetland; a combination of limited deliberate planting along with natural colonization whenever the reclamation permit can be adjusted to allow the 3 to 4 years commonly necessary for such colonization; the establishment of self-perpetuating marsh vegetation confirmed over a 3-year period of observation as a minimum requirement for determining permit compliance. Longer term monitoring of pits reclaimed under these guidelines could provide information that would increase and refine post-mining land-use options for wet sites. Research projects could focus on learning more about development of wetland functions within created systems, eventually providing standards for evaluation on a functional level.

“…SMS contains a seed bank that includes the seeds, fruits, propagules, and other plant reproductive structures in the soil (Poiani and Johnson 1988). After two full growing seasons, Erwin and Best (1985) found that SMS wetlands in Florida had greater species richness than areas allowed to revegetate naturally. They concluded that SMS seemed to encourage the establishment of late successional plants in sufficient quantities to compete with aggressive weedy species such as broad-leaved cattail (Typha latifolia).…”

To evaluate the efficiency of different methods of wetland plant establishment and different soil amendments, 16 experimental plots in 4 treatment groups were established at a 6-ha created palustrine wetland in Tipton, PA. Response of vegetation, soil, and hydrology were evaluated. The first objective of the study was to determine if salvaged marsh surface (SMS) from a donor wetland can be used to effectivly vegetate experimental plots. The results were compared with control plots. In addition, the possibility of using a non-toxic organic waste (leaf litter compost) as a soil amendment to created wetland projects was examined. Lurid sedge (Carex lurida) tubers were hand-planted in the leaf litter plots and in the existing mineral soils of the remaining experimental plots. SMS plots had significantly greater plant species richness, total vegetative coverage, and diversity than control plots. SMS plots contained more hydrophytic vegetation and less undesirable vegetation than control plots. SMS added significant amounts of organic matter and soil nutrients (e.g., nitrogen) to the soils in treated plots. Survivorship of hand-planted Carex was greater (79.0 -+ 5.0 % for both July and August 1992) on plots treated with leaf litter compost than on plots with existing mineral soils (45.0 -4-20.0% in July and 38.0 +-_ 20.0 % in August 1992). Organic matter, pH, total N, and N0 s levels were all significantly greater on leaf litter plots than on hand-planted plots after the 1991 growing season. At the end of the 1992 growing season, organic matter, pH, N03, and NH 4 levels were significantly greater on leaf litter plots than on hand-planted plots. The results of the study suggest that SMS can be used as a method to successfully revegetate created wetlands. Also, the addition of leaf litter compost to experimental plots helped to retain soil moisture and provide nutrients that enhanced survivorship of hand-planted Car~x.
