Ponds

Permanent and seasonal standing water bodies up to 2ha in extent.
 

Not connected to each other or to other water bodies – and are only fed by rainwater or groundwater.

High quality ponds form particularly significant elements of the landscape, for example pingos in the Brecks.

Importance for wildlife

Ponds support about two-thirds of all freshwater species while providing food and water to non-aquatic animals, such as mammals and reptiles.

Suffolk ponds support wildlife of importance at the European scale, including the Great Crested Newt, Turtle Dove, rare Stoneworts and a host of other species, as well as providing a range of resources and habitat for our more common species.

Factors affecting habitat in Suffolk

  • Pollution and nutrient enrichment damaging wildlife communities and result in a loss of biodiversity
  • Recreation and sporting use having detrimental impacts e.g. disturbance to wildfowl & trampling of vegetation; stirring up sediments by boats destroys aquatic plants and contributes to enrichment.
  • Infilling due to farming and development. Ponds are not valued and are seen as expendable.
  • Introduction of non-native plants and animals, including fish, affecting biodiversity. Recreational fishing may lead to the loss of natural populations and may affect plant and invertebrate communities.
  • A change in water supply and throughput (e.g. due to water abstraction) alters the character of water bodies. A rise in temperature will produce wide ranging effects e.g. acceleration of plant growth.

Habitat management advice

  • Maintain natural processes: The guiding principle is continuity of habitats, thus maintenance of mosaic is best achieved by phased treatment.
  • Maintain habitat heterogeneity: margins have greater biodiversity than open water. Maintain a mix of vegetation, bare marginal substrate and beds of submerged vegetation. Before managing determine the conservation value of the pond, removing vegetation to create diversity risks losing fauna dependent on a single margin type.
  • Over-managing can be detrimental to the fauna; all successional stages are of value, and while some species require unshaded conditions, others thrive in shaded ponds.
  • Maintain water quality and water levels.
  • Temporary pools have great conservation value and should not be filled in or excavated to create permanent water bodies.
  • Maintain gently sloping bank profiles.
  • Adopt small-scale rotational management. If material must be removed, do it in August so that over-wintering and pupating individuals will not be present; April to June are the worst months for such work.
  • Minimise disturbance resulting from recreational use.
  • Light grazing around the pond can be used to prevent scrub invasion.
  • If a pond has recently become shaded, it should be cleared, particularly to the south. Shaded woodland ponds should not be opened up without good reason.

Vision for Suffolk

  1. Improve knowledge of extent and quality of ponds.
  2. Maintain the existing extent of ponds to ensure no net loss.
  3. Re-create ponds as opportunities arise.
  4. Encourage the restoration and improvement of degraded ponds.
