  • Ireland & the Landscape Ireland
    Ireland & The Landscape Ireland : the land and the landscape Grenville A. J. Cole 1914 • The Structure of Ireland. The description of the country...contains a number of local details which may arouse interest, when the reader says to himself, “ I have seen that,” or “ I know that very corner.” The teacher may well begin with the country round about the school, and may mention a great many of its surface-features, aided by the Ordnance Maps, beyond what is briefly touched on here. Old traditions and historic events add greatly to the interest of such descriptions ; and the beautiful Irish place-names, which are so often ruined by the spelling on our maps, con-stantly remind us of the curves of hill and dale, or connect these land-forms with the move-ments of man, with fights and forays, or with the establishment of seats of learning in the past. Books like P. W. Joyce’s “ Irish Names of Places” and “ Short History of Ireland,” and J. Cooke’s edition of Murray’s “ Ireland,” readily suggest themselves as guides. But the history of Ireland goes far back beyond what man has written, and is bound up with that of the great globe itself. Those who live in Ireland should know their country well. If these few pages should help anyone to know and love it better, the author will have received his best reward. G. A. J. C. Carrickmines, July, 1914 • Just as Arranmore, Inishbofin, or Clare Island lie off Ireland, while the sea stretches inland to the east of them, so Ireland lies off the western edge of the enormous mass of land known as Eurasia, or Europe and Asia considered as a whole.

  • Status of Fish Stocks in the River Maigue Catchment
    Status of Fish Stocks in the River Maigue Catchment Author: Tom Harrington, Vice-Chairperson, Maigue Rivers Trust 1. Introduction The River Maigue rises in the Milford area of north Co. Cork to the west of Charleville. It flows in an easterly direction and then north past Charleville, and through Bruree, Croom and Adare. It joins the Shannon Estuary at Carrigclogher Point. The 20km tidal section downstream of Adare to the Upper Shannon Estuary, is included in the Lower Shannon SAC (Special Area of Conservation). The Maigue estuary contains habitats of high conservation value that are influenced by the tide. The Maigue catchment drains an area of 1020 km2 predominantly in Co. Limerick, and is a significant sub-catchment of the Lower Shannon. There are a number of significant tributaries; the Glen River and the Loobagh, join near Charleville, the Morningstar downstream of Bruree, the Camogue upstream of Adare and the Greanagh and Barnakyle downstream of Adare. There are also a number of smaller tributaries such as the Gloshagh. The Camogue River is the largest of the tributaries forming an extensive sub-catchment, which, with its headwater tributaries the Ballynamona, Mahore and Dromcamogue Rivers, extends eastwards beyond Emly in Co. Limerick. Lough Gur, the only significant lake in the catchment, is part of the Camogue drainage. All of the catchment rivers are lowland in character. The only exceptions are the headwaters of the R. Loobagh which flow from the Ballyhoura Mountains and Slievereagh Hills near Kilfinnane. Significant stretches of all major tributaries were subjected to arterial drainage work in the 1970s, and this has changed the natural character of the rivers considerably in many stretches.

  • Water Quality - Existing Status & Management System
    Catchment Monitoring Water Quality - Existing Status & Management System Conclusions Lake water quality is in a satisfactory condition in the upper reaches of the River Shannon. Progressive increases in the levels of planktonic development are noted in lakes downstream of the oligotrophic Lough Allen to Lough Ree, and in Lough Key on the Boyle River, attesting to increasing nutrient inputs to the inflowing rivers. While many of these lakes are still classified as mesotrophic (Table 13) they are at the upper boundary limit of this category and if current trends are maintained these lakes will soon be classified as eutrophic. Lough Forbes already has planktonic algal developments consistent with such a category. Lough Ree has been classified as strongly eutrophic in recent years and the findings of the recent monitoring point to a continuation of the decline in the water quality of this lake. The unsatisfactory water quality of a number of rivers in the catchment, noted in 1993-94, still persists and the nutrient loads carried by these rivers support the excessive algal growths recorded in the lake. No improvement in the water quality of Lough Ree can be expected until the sources of the nutrients are significantly reduced or eliminated. Increased light penetration and reduced planktonic algal populations were recorded in Lough Derg in 1997 indicating a considerable improvement in the water quality of the lake, particularly in the middle and lower sections of the lake, compared to previous years (further improvements in these parameters were noted in July 1998). This welcome improvement in water quality in the lake may be attributed to two developments.
