“…It is only recently that the value of ponds as a biodiversity resource (Williams et al 2004), carbon sink (Downing et al 2008), floodwater management tool and pollution filter (Fiener et al 2005) has been recognised. Even when managed for mankind's use, ponds can still contribute to biodiversity, as has been shown for motorway stormwater retention ponds in France (Scher et al 2004) and angling ponds in England (Wood et al 2001).…”

Environmental correlates of plant and invertebrate species richness in ponds

Ponds (lentic water bodies <2ha) constitute a considerable biodiversity resource. Understanding the environmental factors that underlie this diversity is important in protecting and managing the habitat. We surveyed 425 ponds for biological and physical characteristics with 78 of those also surveyed for chemical characteristics. A total of 277 invertebrate species and 265 plant species were found. Species richness varied between 2 and 99 (mean 27.2 ± 0.6 SE) for invertebrates and 1 and 58 (mean 20.8 ± 0.4 SE) for plants. Generalised linear models were used to investigate variables that correlate with the species richness of plants and invertebrates, with additional models to investigate insect, Coleoptera, Odonata, Hemiptera, Trichoptera and Mollusca species richness. Models performed well for invertebrates in general (R 2 =39.8%) but varied between lower-order invertebrate taxa (8.2-34.9%). Ponds with lower levels of shading and no history of drying contained higher numbers of species of plants and all invertebrate groups. Aquatic plant coverage positively correlated with species richness in all invertebrate groups apart from Trichoptera and the presence of fish was associated with high invertebrate species richness in all groups apart from Coleoptera. The addition of chemistry variables only increased the explanatory power of the model explaining plant species richness, for which phosphate was a highly significant factor. We demonstrate that the composition of biological communities varies along with their species richness and that less diverse ponds are more variable compared to more diverse ponds. Promoting a high landscape-level pond biodiversity will involve the management of a high diversity of pond types within that landscape.

“…Edwards et al (1999) reported sediment basin TN and TP trapping efficiencies of 72e81% and 32e66%, respectively. Other researchers have also indicated that sedimentation basins are effective in reducing the amount of sediment and nutrients entering surface waters of agricultural watersheds (Edwards et al, 1999;Czapar et al, 2005;Fiener et al, 2005). Runoff with total suspended solid concentrations of about 200 mg L À1 was also reported to have decreased to levels between 5 and 20 mg L À1 with the installation of a sedimentation basin (Barrett, 2008).…”

, "At-grade stabilization structure impact on surface water quality of an agricultural watershed" (2015). USGS Decades of farming and fertilization of farm land in the unglaciated/Driftless Area (DA) of southwestern Wisconsin have resulted in the build-up of P and to some extent, N, in soils. This build-up, combined with steep topography and upper and lower elevation farming (tiered farming), exacerbates problems associated with runoff and nutrient transport in these landscapes. Use of an at-grade stabilization structure (AGSS) as an additional conservation practice to contour strip cropping and no-tillage, proved to be successful in reducing organic and sediment bound N and P within an agricultural watershed located in the DA. The research site was designed as a paired watershed study, in which monitoring stations were installed on the perennial streams draining both control and treatment watersheds. Linear mixed effects statistics were used to determine significant changes in nutrient concentrations before and after installation of an AGSS. Results indicate a significant reduction in storm event total P (TP) concentrations (P ¼ 0.01) within the agricultural watershed after installation of the AGSS, but not total dissolved P (P ¼ 0.23). This indicates that the reduction in P concentration is that of the particulate form. Storm event organic N concentrations were also significantly reduced (P ¼ 0.03) after the AGSS was installed. We conclude that AGSS was successful in reducing the organic and sediment bound N and P concentrations in runoff waters thus reducing their delivery to nearby surface waters.

“…Sediment basins or ponds are defined as off-site surface water management structures, which capture runoff and sediment in an artificial impoundment and prevent sediment discharge into downstream lakes and reservoirs (Iqbal et al, 2003;Fiener et al, 2005). Sediment ponds are built within channels or at the edge of fields to trap sediment from concentrated runoff and thus prevent off-site sedimentation (Figure 3.5).…”

“…On-site ST measures reduce overland flow velocity and thereby retard sediment transport, resulting in sediment deposition within fields before sediment can be discharged into streams (Fiener & Auerswald, 2003;Lee et al, 2003;McKergow et al, 2004;Edem et al, 2012;Wanyama et al, 2012). Off-site ST measures reduce concentrated runoff velocity within the (ephemeral) gully and river channel system thereby enhancing infiltration of water and deposition of sediment into ponds and behind check dams (Fiener et al, 2005;Abedini et al, 2012) and into the riparian zone (Newson & Large, 2006;Keesstra et al, 2012).…”
