THE CHAROPHYTA OF COUNTY DUBLIN (H21)

Between 1988 and 1992, 69 sites from a total of 132 examined in County Dublin yielded charophytes. Sites ranged in size from canals and rese rvoirs to cattle drinking troughs and included locations of flowing, s till and standing water. Eleven species of Charophyta, covering the ge nera Chara, Nitella and Tolypella, were recorded. In addition, physico -chemical analysis for a number of variables was carried out on water samples from 32 locations which yielded charophytes. The findings are discussed in relation to previous records for the vice-county and to a spects of the ecology of the recorded species as reported in the liter ature.
