“…2, 3, and 4). The legacy of past land use may be preserved in a number of chemical, physical, and biological aspects of an ecosystem and may have consequences for ecosystem management and restoration efforts (3,23,(28)(29)(30)44).…”

“…Land use change can have significant and longterm effects on the soil environment by influencing parameters such as fertility, hydrology, redox status, and biodiversity. These changes will affect microbial community structure and function, both directly and indirectly (3,21,27,37,67). Microbial populations differ in their sensitivities to land use change; thus, past land use may have lasting consequences for the composition and activity of soil microbial communities.…”

Wetland mitigation is implemented to replace ecosystem functions provided by wetlands; however, restoration efforts frequently fail to establish equivalent levels of ecosystem services. Delivery of microbially mediated ecosystem functions, such as denitrification, is influenced by both the structure and activity of the microbial community. The objective of this study was to compare the relationship between soil and vegetation factors and microbial community structure and function in restored and reference wetlands within a mitigation bank. Microbial community composition was assessed using terminal restriction fragment length polymorphism targeting the 16S rRNA gene (total bacteria) and the nosZ gene (denitrifiers). Comparisons of microbial function were based on potential denitrification rates. Bacterial community structures differed significantly between restored and reference wetlands; denitrifier community assemblages were similar among reference sites but highly variable among restored sites throughout the mitigation bank. Potential denitrification was highest in the reference wetland sites. These data demonstrate that wetland restoration efforts in this mitigation bank have not successfully restored denitrification and that differences in potential denitrification rates may be due to distinct microbial assemblages observed in restored and reference (natural) wetlands. Further, we have identified gradients in soil moisture and soil fertility that were associated with differences in microbial community structure. Microbial function was influenced by bacterial community composition and soil fertility. Identifying soil factors that are primary ecological drivers of soil bacterial communities, especially denitrifying populations, can potentially aid the development of predictive models for restoration of biogeochemical transformations and enhance the success of wetland restoration efforts.Wetlands provide more ecosystem services (e.g., flood control, water purification, nutrient cycling, and habitat for wildlife) per hectare than any other ecosystem (16). Riparian wetlands, in particular, are sites of intense biogeochemical activity and play an important role in improving water quality, recycling nutrients, and detoxifying chemicals (41). Changing patterns of land use over the last century have resulted in the loss of over half of the wetlands in the contiguous United States (17) and about 60% of wetlands in the Midwestern United States (82). The loss of ecosystem services through conversion of wetlands to alternative (primarily agricultural) land uses exacerbates nutrient pollution and eutrophication of downstream ecosystems (57). Declines in wetland acreage have continued despite a federal policy goal of no-net-loss of wetland acreage and function adopted in 1990 (7, 55). Wetland mitigation projects provide compensation for impacted wetlands and aim to replace the critical functions provided by wetlands. Despite decades of wetland mitigation, however, restoration efforts frequently fail to reestablish desired...

“…Microbial activity increases with temperature. Microbial populations in the East Pond were related to DOC extracted from the soils (Bossio et al 2006). Assuming that low winter temperatures and physical plant structure cause a lag between initial plant material deposition and decomposer growth, the timing of DOC production from plant materials that causes elevated DOC concentrations in the outlets coincide well.…”

“…The decrease in abundance of the soil mesofauna community indicates a slowing of organic matter decomposition and alteration of soil microbial communities, both parameters being of primary interest for estimating wetland restoration success (e.g. Bossio et al 2006). The observed differences in response between Collembola and Oribatida, two taxa competing for the same food resources but differing in life history traits, in consistently submerged restored wetlands also support the claim that restoration processes have been successfully initiated in mountain fens.…”

The research was designed to assess benefits of passive restoration, consisting of blocking from drainage ditches and in effect raise the groundwater level, its influence on properties of soil, water, species of plants and mesofauna in the fen CalthoAlnetum community. The research was carried out in Outer Flysh Carpathians, the area of the Babiogórski National Park (Poland) in 2011-2014. It was established that the degraded communities showed positive reaction to an attempt to restore the original groundwater level. The increase in the groundwater level changed chemical properties of soil and water of the community such as: pH, sorption properties and the ionic composition of groundwater. Changes in habitat conditions resulted in different species composition of soil mesofauna and plants growing in the restorative community.
