The city’s waterways seem an unlikely habitat for finding otters in but as always nature can surprise you.

The need for monitoring became apparent after improvements were made to the stream but with no real way to measure the impact these changes had potentially had. Alongside the Riverfly populations the stream’s health is also monitored for…
