MetadataShow full item record
- NIVA-rapport 
The report presents update results for trends in biology after 2000. The results confirm the results from the ICP Waters report in 2000 and shows continued improvement in biological recovery from regions with new data. The recovery of sensitive fauna corresponds with the chemical recovery of lakes. The improvements is most pronounce in Scandinavia (Norway) and Canada. A beginning recovery is recorded in the Czech Republic, while unstable (not significant) improvements are recorded in Germany. The lagtime in recovery of different species/communities is evaluated to vary from a few to about 20 years, after reaching their critical limit.
