Commoge Marsh














Habitat Map | Management Plan Summary





 

Confirmed list of important features

Brackish lagoon with lagoon specialist fauna

A fairly typical brackish lagoon of artificial origin, which holds a number of typical lagoonal fauna species, some of which are nationally scarce. The statutory body for nature conservation in Ireland, National Parks and Wildlife Service (NPWS), have given preliminary indications that the site is to be designated as a Natural Heritage Area (NHA).

Broad Policy: To provide conditions, through management, which optimise the quality of this habitat for its lagoonal specialist species.

For further information about coastal lagoons and the specialised species that they support, see:

Scarce flowering plant populations

The marsh holds three scarce plant species: Dotted Sedge, Yellow Bartsia and Chaffweed.

Click here for more details of flowering plants.

Broad Policy: To retain and improve marginal wetland habitats suitable for Dotted Sedge, Yellow Bartsia and Chaffweed. To monitor populations of these three species on an annual basis.

Non-breeding bird populations

The marsh is an important element in the wider Bandon River Estuary for non-breeding waders and wildfowl. On occasion the marsh holds nationally important concentrations of a number of species including Black-tailed Godwit, Curlew and Greenshank.

Click here for more details of birds.

Broad Policy: To enhance the attractiveness of the marsh for waders, wildfowl and other birds.

Species rich wet grassland

A diversity of habitat types which vary greatly in terms of their ecological value, diversity and extent. Some species-rich areas are of high conservation importance and hold rare plant species (see above).

Broad Policy: To reinstate, enhance and create areas of marginal, species-rich, saline-influenced wet grassland.

Salt marsh

A small area of rather atypical lower salt marsh, which lacks species of saltmarsh grass.

Broad Policy: To retain areas of this habitat within Commoge Marsh in order to retain overall biodiversity within the Marsh.

 

Wet willow-alder-ash woodland

A fairly small but diverse area of Alder woodland which fringes the marsh and also protects the marginal habitats from human disturbance.

Broad Policy: To retain areas of this habitat within Commoge Marsh in order to retain overall biodiversity within the Marsh. To protect this habitat from recent increases in disturbance levels and where possible to expand the area of this habitat type around the fringes of the marsh, beyond the existing wetland areas.

 

Reed and tall sedge swamp and tall herb swamp

An area of relatively diverse reed and tall sedge swamp which appears to be increasing over time at Commoge Marsh, and a small area of near-freshwater tall herb swamp which is also likely to increase.

Broad Policy: To retain areas of this habitat within Commoge Marsh in order to retain overall biodiversity within the Marsh.

 

Ecotonal invertebrate fauna

The ecotonal invertebrate fauna of the marsh has been partially surveyed and indications are that it may be of conservation value.

Broad Policy: To conduct further survey work in order to gather sufficient data to evaluate the importance of this community.

 

Potential for education, research and amenity use

This includes the potential for organised or casual birdwatching; research into, for example, lagoon management; etc.

Broad Policy: To consider placing a bird watching hide and other visitor amenities at the site.
