“…In 1999, the effectsbased Gothenburg Protocol on long-range transboundary air pollution was signed with the intent to reduce emissions of S and N oxides, and ammonia in Europe (63, 41, and 17%, respectively) by 2010 (UNECE 1999). These emission reductions have stimulated widespread significant changes in the chemistry of acid-sensitive lakes (Stoddard et al 1999;Skjelkvåle et al 2005;Kopáček et al 2004).…”

A re-survey of acid-sensitive lakes in Ireland (initial survey 1997) was carried out during spring 2007 (n = 60). Since 1997, atmospheric emissions of sulfur dioxide and deposition of non-marine sulfate (SO 4 2-) in Ireland have decreased by *63 and 36%, respectively. Comparison of water chemistry between surveys showed significant decreases in the concentration of SO 4 2-, nonmarine SO 4 2-, and non-marine base cations. In concert, alkalinity increased significantly; however, no change was observed in surface water pH and total aluminum. High inter-annual variability in sea salt inputs and increasing (albeit non-significant) dissolved organic carbon may have influenced the response of pH and total aluminum (as *70% is organic aluminum). Despite their location on the western periphery of Europe, and dominant influence from Atlantic air masses, the repeat survey suggests that the chemistry of small Irish lakes has shown a significant response to reductions in air pollution driven primarily by the implementation of the Gothenburg Protocol under the UNECE Convention on Long-Range Transboundary Air Pollution.

“…While Nižné Terianske pleso was (and remains) relatively non-sensitive to acidification, with pH > 6.0, and acid neutralising capacity (ANC) > 25 µeq L −1 , Starolesnianske pleso was extremely sensitive to acidification, characterised by pH < 5.0, and ANC < 0 µeq L −1 (Kopáček et al 2004). Despite clear signs of a reversal from acidification since the 1990s , this lake remains acidified to the present.…”

“…To reveal and assess recovery, however, knowledge of the pre-acidification faunal composition is needed. Earlier published and unpublished data can be considered an important "background" of the Tatra Mts lake fauna before the onset of acidification in the 1950s (Kopáček et al 2004). Respectively, data from the late 1990s and 2000s could be expected to reveal some signs of biological recovery.…”

“…The first signs of lake water recovery from acidification were seen at the beginning of the 1990s (Kopáček et al 2004) as a consequence of a large drop in the emission of sulphur and nitrogen compounds throughout Europe. The recovery process in the Tatra Mts has been considered to be the most extensive of European mountain ranges (Wright et al 2005).…”

“…Remote lakes situated above timber-line and on acid sensitive geology were extremely sensitive to acid atmospheric deposition. Compared with other European mountain ranges, the Tatra Mts have been exposed to the strongest effects of acidification pollutants for more than a half of the century (Kopáček et al 2004). Acidification caused significant changes in water chemistry that induced water toxicity, influenced lakes' trophic status, and led to serious changes in the structure of planktonic and benthic communities in many Tatra Mts lakes (Stuchlík et al 1985;Krno 1991).…”

Benthic macroinvertebrate fauna of two alpine lakes over the last century: The value of historical data for interpreting environmental changes

2010

Data on benthic macroinvertebrate assemblages of two alpine lakes in the Tatra Mts (Slovakia) collected in 1914, 1933, 1979-1982, 1993-1997, and 2000 were collated and analysed in an attempt to define their relationship to major environmental events affecting these alpine lakes over the last century. The oldest data were considered an important background before the onset of acidification in one of the lakes in the 1950s, while the most current contain possible information on biological recovery. Results show that data from the 1910s are insufficient to characterize the macroinvertebrate fauna. Deep zone assemblages of both studied lakes have remained stable since the 1930s. Changes in the density of dominant species over time were found in the acidified lake, suggesting a connection between an increase in phosphorus and chlorophyll-a concentration. The composition of the littoral assemblages in the acidified lake in the 1930s indicates that the lake was not strongly acidified at that time. A stable composition since the 1980s reflects the ongoing acid stress. Incomplete species data on the non-acidified lake did not allow us to detect possible changes in the littoral fauna related to acidification. Single findings of species indicating a recovery process need longer-term data to confirm such a trend. Results from this study suggest that historical datasets consist of valuable information that can supplement palaeolimnological analyses in the reconstruction of lake ontogeny.

Forest, climate and water issues in Europe

The particular European perspective on current forest and water issues is outlined in three focal areas: water supply, water quality, and water-related hazards. Much of the synopsis relies on contributions brought together within the European COST consortium 'Forest management and the water cycle', which is operating from 2007 to 2011. Under the currently projected climate change (CC) scenarios for Europe, the humidity gradient across the sub-continent from moist Northwest to dry Southeast will probably intensify, bringing about potentially more flooding problems at the 'wet end', and more drought and related problems (wildfires, salination) at the 'dry end'. Careful planning of management is essential wherever tradeoff situations between forest growth and water yield emerge. The water quality issue in Europe is not as pressing as it was a few decades ago. Much has been achieved on account of successful water-and air-pollution control. Particularly, the acidification pressure on forest soils and their water-related systems was much relieved, due to strongly declining acidic deposition over the past 30 years. Forests and their appropriate management for optimizing water retention can support flood control, but with clear limitations under very strong and catastrophic events. The contribution to flood control is more important under 'normal' conditions than under extremes. Important controls are infiltration capacity and the status of water saturation prior to the rain event, i.e. the still available storage capacity. The safeguarding of water quality is seen as the most important single aspect among forest-water relations.
