Commoge Marsh

Habitat Map | Management Plan Summary


Factors which influence, or may influence, the important features of Commoge Marsh

Positive Factors

  • The objectives of the landowners to manage the site for nature conservation.

  • Seral succession which may be suspended by salinity thus retaining wetland features.

  • The relatively high freshwater inputs to the marsh which makes it resilient to hypersalination.

  • The open water exchange to the Bandon River estuary which makes the marsh resilient to hyposalination.

  • The sluice gates which can be used to control salinity and water levels within the marsh.

  • The decreasing potential for contamination from agricultural run-off as an increasing proportion of the catchment is taken out of agriculture.

  • Requirements for habitat creation and improvement outlined in various mitigation measures and planning conditions relating to past present and future development in the vicinity of the marsh.


Negative Factors

  • Seral succession which may result in drying-out of wetland features.

  • The increasing level of visual and noise disturbance as a result of development in the vicinity of the marsh.

  • The increasing level and potential for direct damage to the features of the marsh as a result of the increased number of people in the vicinity of the marsh.

  • The potential for contamination to the marsh resulting from the continuing development in the vicinity.

  • The unknown status of some of the features of the marsh such as ecotonal invertebrates.

  • The difficulty of accessing the marsh in order to carry out routing maintenance of, for example, the sluice gates, and to carry-out other management tasks.

  • The limited range of water depths within the marsh which may limit the range of specialist lagoonal fauna which inhabit the marsh.

  • Continued malfunctioning of the sluice gates leading to excessively high water levels and salinity levels within the marsh.

  • The limited length of shoreline within the marsh, which limits the available habitat for a number of the important features of the marsh.

  • Limited availability of resources for management tasks.
