About Otters
The otter is a fully protected mammal that experienced a massive decline in its population due to the introduction of Dialdrin and DDT as pesticides in the late 1950s. Since the ban on these chemicals, numbers of otters have gradually increased and the species is now known to occur in areas where it was previously absent. These even include urban rivers and those with a historical association with heavy industrial pollution.
Given the increase in the distribution of the otter, general river quality cannot be relied upon as an indicator of presence or absence of the species. Otter surveys are now recommended where river banks and other riparian habitat are affected by development or river works.
