“…Coniferous vegetation is not expedient as it inhibits the growth of herbaceous species (e.g. Craine & Orians, 2004) and alters the water chemistry (Klimaszyk et al, 2015). The proposed type of buffer effectively limits the flow of nutrients from surface and soil runoff and increases the supply of organic matter, which enhances the potential of the biocoenosis development.…”

Effect of agricultural landscape characteristics on the hydrobiota structure in small water bodies

Understanding the influence of environmental factors on the hydrobiota structure of small aquatic ecosystems is essential for effective landscape management. In this study of 165 small water bodies situated in the lowland high-productive agricultural landscape of western Poland we evaluate the effect of catchment, buffer zone, water body and water quality parameters on macrophyte functional groups (nymphaeids, elodeids, pleustophytes, helophytes) and zooplankton diversity. The potential pressure of the catchment on ponds was high (mean Ohle index 140). For macrophytes, shore length and depth of pond were highly significant and, subsequently the type of catchment and buffer, while for zooplankton, apart from water depth, trophic features of the habitat were decisive. Cluster analysis was used to identify functional types of water bodies on the basis of catchment and buffer zone attributes. Regardless of physicogeographical macroregion, water bodies of arable catchments with herbage buffer prevailed in a landscape. For protection and prevention of ecological deterioration of ponds and stability of trophic conditions the optimal situation is a buffer which is created by shrubs and trees around the pond.

“…However, differences in shading, land use and conductivity between the Pinkhill ponds and other new ponds indicated that some of the former's richness might be attributable to their open unshaded aspect, their seminatural grassland surrounds and/or their low chemical conductivity. Of these, shade, is known to be associated with lower species richness, particularly for macrophyte assemblages (Gee et al, 1997;Craine & Orians, 2004;Biggs et al, 2005). Semi-natural grassland land use and conductivity (assuming the latter to be a surrogate for nutrient pollution) are also clearly plausible influences promoting the richness in the Pinkhill ponds.…”

How can we make new ponds biodiverse? A case study monitored over 7 years

A new pond complex, designed to enhance aquatic biodiversity, was monitored over a 7-year period. The Pinkhill Meadow site, located in grassland adjacent to the R. Thames, proved unusually rich in terms of its macrophyte, aquatic macroinvertebrate and wetland bird assemblages. In total, the 3.2 ha mosaic of ca. 40 permanent, semi-permanent and seasonal ponds and pools was colonized by approximately 20% of all UK wetland plant and macroinvertebrate species over the 7-year survey period. This included eight invertebrate species that are Nationally Scarce in the UK. The site supported three breeding species of wading bird and was used by an additional 54 species of waders, waterfowl and other wetland birds. The results from four monitoring ponds investigated in more detail showed that these ponds significantly supported more plant and macroinvertebrate species than both minimally impaired UK reference ponds, and other new ponds for which compatible data were available.Comparisons of the physico-chemical, hydrological and land-use characteristics of the Pinkhill pools with those of other new ponds showed that the site was unusual in having a high proportion of wetlands in the near surrounds. It also had significantly lower water conductivity than other ponds and a higher proportion of (non-woodland) semi-natural land in its surroundings. Given that ponds are known to contribute significantly to UK biodiversity at a landscape level, and that several thousand new ponds are created each year in the UK alone, the findings suggest that well designed and located pond complexes could be used to significantly enhance freshwater biodiversity within catchments.

“…Shrub recruitment to coastal plain pondshores may occur by vegetative reproduction from the upland pond-shore edge or by occasional rain of short-lived seeds of tree or shrub species (Craine and Orians, 2004). It is also possible that the moist soil conditions provided in the growth chambers were inappropriate for most shrub species.…”

“…Pumping of ground-water for municipal use can lower water levels and reduce the occurrence of the high water levels needed to prevent shrub encroachment to the pond-shore (Craine and Orians, 2004;McHorney and Neill, 2007). Climate change in the northeastern US is projected to cause higher annual precipitation but higher precipitation variability and greater incidence of short-term drought (NECIA 2006).…”

“…Prolonged inundation during years or multiple years with high water levels generally eliminate adult plants of most shoreline grasses and forbs and prevent encroachment of woody shrubs and trees into lower-elevation portions of pond shorelines (Sorrie, 1994;Craine and Orians, 2004;McHorney and Neill, 2007). Plants that occupy coastal plain pond shorelines generally tolerate the acid and low-nutrient conditions that prevail in these ecosystems because of the ponds' geologic origin in areas of coarse and acidic soils formed predominantly on acidic glacial outwash (Oldale, 1974;Fletcher, 1993;Sorrie, 1994;Wisheu and Keddy, 1989).…”
