The Otter (Lutra lutra) almost become extinct in England from the mid 1950’s through to the early 1970’s due to river pollution and in particular organochlorine pesticides. This month Environment Agency announced that the otter is now to once again to be found throughout England with 59% of traditional otter sites surveyed (2,940) now colonized compared to just 6% in 1979. Rivers in England are now the cleanest they have been for the past 20 years and with fish stocks improving recolonization of rivers by otters and salmon has been seen as the last step in the restoration of England’s rivers. Link Otters are also very common on many Irish rivers, but as numbers of otters increase there are concerns from many fishing clubs that their restocking and restoration work is simply filling the otter’s larder! This has led to some conflict between conservation and angling organizations.
Water Science and Water Technology are core research areas at Trinity College Dublin, Ireland. Working in the fields of wastewater treatment, water treatment and water pollution control, the Water Technology Research Group (formally Water Technology Research) has been working at the cutting edge of these core areas since 1980. This is the blog of Professor Nick Gray who heads the Water Technology Research Group based in the Centre for the Environment.
