“…We found differences in the composition of macroinvertebrate assemblages, but in this study the overall level of biodiversity was comparable among the three ecosystem categories. Some authors have found similar taxa richness in natural wetlands and in 1 to 10 year-old constructed wetlands (Barnes, 1983;Stanczak and Keiper, 2004;Hansson et al, 2005;Spieles et al, 2006), but critics often argue that certain aspects of created wetlands (e.g., plant communities and soils) can not be similar to natural wetlands for at least almost 5 years (Campbell et al, 2002). Miguel-Chinchilla et al (2014) have recently demonstrated that environmental factors better explain the pond biodiversity than pond age, influencing the number and type of taxa that are able to colonize man-made ponds.…”

“…Macroinvertebrates are directly affected by the physical and chemical integrity of the surrounding environment, including water quality (EPA, 2002). They are known to influence the rates of nutrient cycling and decomposition, to have a central position in the wetland food webs and to integrate environmental impacts and changes through time (Scatolini and Zedler, 1996;Sharitz and Batzer, 1999;Brady et al, 2002;Stanczak and Keiper, 2004). Therefore, they are potentially useful as indicators of restoration success (Campbell et al, 2002).…”

“…The ability of vascular plant presence, cover, density and composition to influence the structure and function of wetlands has been widely recognized (Leonard & Luther 1995, Levin & Talley 2000. Plant effects on salt marsh sediments and biota have been elucidated through investigations of newly restored ecosystems (Levin et al 1996, Craft & Sacco 2003, Stanczak & Keiper 2004 and by tracking changes following plant invasion (Posey 1988, Posey et al 1993, Talley & Levin 2001.…”

A hybrid cordgrass, formed from a cross between Spartina alterniflora (Atlantic cordgrass) and S. foliosa (Pacific cordgrass), has recently spread within the intertidal zone of south San Francisco Bay. Sediment properties and macroinfaunal community structure were compared in patches invaded by Spartina hybrid and adjacent uninvaded patches at 3 sites in San Francisco Bay (2 tidal flats and 1 Salicornia marsh). We hypothesized that (1) sediments vegetated by Spartina hybrid would have reduced sediment grain size, higher organic matter content, lower redox potential, lower salinity and reduced microalgal biomass relative to adjacent unvegetated tidal flat sediments, and (2) that differences in the sediment environment would correspond to changes in the infaunal invertebrate community structure and feeding modes. We observed 75% lower total macrofaunal density and lower species richness in Spartina-vegetated sediments at Elsie Roemer (30 yr old invasion) than in an adjacent unvegetated tidal flat. This was due to lower densities of surface-feeding amphipods, bivalves, cirratulid and spionid polychaetes. The proportional representation of subsurface-deposit feeders was greater in Spartina patches than in unvegetated sediments. At a more recently invaded site (Roberts Landing; 15 yr invasion), Spartina patches differed from tidal flat sediments in composition, but not in abundance. Native (Salicornia) and Spartina patches exhibited similar sediment properties at San Mateo, where the Spartina hybrid invaded 8 to 10 yr earlier. No differences were detected in densities or proportions of surface-or subsurface-deposit feeders, but the proportion of carnivores/omnivores and grazers increased in the hybrid-invaded patches. These studies suggest that the invasive Spartina hybrid in south San Francisco Bay can have differing effects on sediment ecosystems, possibly depending on the location, age, or type of habitats involved.

“…Our results suggest that 7 years were sufficient to recover a Brachycera species community and a level of diversity (in two of the bogs) characteristic of a natural bog, but not trophic composition or the small sized species assemblage. It is difficult to determine the time needed for complete recovery of invertebrate species assemblages in restored wetlands; estimates range from 4 to 17 years (Streever et al 1996;Stanczak and Keiper 2004).…”

Peat mining causes major degradation to bogs and natural regeneration of these sites is slow and often incomplete. Thus, restoration is an important tool for re-establishing natural ecosystem properties (although perhaps not the original species pool) in mined bogs. Because faunal recovery cannot be taken for granted following plant restoration, we assessed community assembly of higher flies (Diptera: Brachycera) in previously mined bogs 7 years after restoration. Species assemblages in restored sites were compared to those in nearby natural and abandoned mined sites. The three treatment types did not differ significantly in overall species composition, suggesting high resilience to disturbance. However, species richness and evenness were generally lower in abandoned sites than restored and natural sites, which had similar abundance distributions, indicating that restoration enhanced recovery of species diversity and community structure. Functional traits (trophic group, body size) provided a different insight into the status of restored sites. Trophic and small size-class (\5 mm) composition in restored sites were similar to those in abandoned sites. However, high species richness estimates indicated that predators and saprophages successfully colonized restored sites. Species assemblages were mostly affected by coverage of bare peat, Sphagnum mosses and ericaceous shrubs; trophic assemblages were affected by variables directly linked to feeding habits. Our results suggest that active restoration is needed for the renewal of high species and trophic diversity, although it is clear from environmental conditions and functional traits that the restored sites are not yet fully functioning peatlands 7 years after restoration.
