Other Site Characteristics

The River Shannon is the largest river in Ireland, and its central route drains a large percentage of the whole country. It has proved too powerful to be tamed by drainage schemes in the past, and this central section is still free to flood the surrounding lowlands in winter. It is a well-used agricultural resource of low intensity during the summer. This floodplain functions as a semi-natural meadow/marsh habitat (used for grazing or hay-making). There is an extensive system of surface drains. The site is linear, running for about 50 km, at an average width of about 0.75 km (but reaching 1.5 km in several places). For about half its length it borders raised bogs, most of which are in the process of large-scale peat harvesting. Esker ridges lie adjacent to the callows in some places. There are areas of both relict and active levees. A weir at Meelick divides the flooding regime. Ecological diversity is caused and maintained by multiple ownership, variation in the flooding regime due to the topography of the callows, hundreds of kilometres of drainage ditches, differences in the amount of peat and alluvium in the soils and by the extensive nature of the site. The main habitat on the site is humid grassland managed for hay and pasture and these areas have the same management regime as the lowland hay meadows and Molinia meadows.

4.2 Quality and importance

This site is the largest area of semi-natural floodplain grassland in Ireland and Britain and has very many features of a natural ecosystem. It has been placed among the most 'natural' floodplains in western Europe. It is subject to regular and prolonged annual winter flooding. Wooded alluvial islands which flood regularly occur at one location. A number of Red Data Book and scarce plant species occur on the site, the scarce species including Leucojum aestivum, Sium latifolium, Botrychium lunaria and Lemna gibba. In addition, the site contains a very wide variety of native plant species. A small area of limestone pavement at Clorhane is of particular importance as it is the only example of this habitat in the region. Along with its tributary the Little Brosna (designated separately) this is one of the great waterfowl sites in Ireland, with huge numbers of a wide range of species occurring in winter, with a mean peak of 34,985 waterbirds recorded from 1995/96 to 1999/00. This is the third highest for an inland site in Ireland. The highest is the Little Brosna, which is an extension to the Middle Shannon Callows. Only three estuarine sites are higher. In 1996/97 one species was of International Importance (Whooper Swan) and six species were of National Importance. A small flock of Anser albifrons flavirostris regularly use a few locations on the site and these are part of the Internationally Important flocks of both the Little Brosna and the River Suck. It is one of very few significant inland sites in Britain or Ireland for Calidris alpina. It is the top site in the country for Cygnus olor and close to that for Cygnus cygnus, Vanellus vanellus and Pluvialis apricaria. The E.U. Birds Directive Annex I species, Circus cyaneus, regularly uses the site for hunting in autumn and winter. Perhaps even more important are its nesting Crex crex, Coturnix coturnix and breeding waders. In 1987, 1204 pairs of breeding waders were recorded (including adjacent parts of the Shannon), mainly Vanellus vanellus, Gallinago gallinago, Numenius arquata and Tringa totanus. Crex crex has one of its last strongholds here with 70 and 66 calling birds present in 1998 and 1999 respectively. The Shannon Callows is one of the few areas in Ireland where Coturnix coturnix breeds. Numbers vary between years but up to 14 males have been heard. There are high populations of ground-nesting passerines, such as Alauda arvensis, Anthus pratensis, Locustella naevia and Emberiza schoeniclus on the site. The River Shannon Callows is a breeding site for two Red Data Book waterbird species: Limosa limosa islandica and Anas clypeata. The Red Data Book species Anas acuta has also bred on the site though its current status is unknown. The E.U. Birds Directive Annex I species Falco columbarius, bred on the site in 1996. Large rivers flowing unfettered through lowland floodplains are now rare anywhere in Europe. This river, and its associated habitats, are of the highest conservation importance.
