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

But since then the numbers have been steadily rising. Survey statistics gathered from Wildlife Trust staff and volunteers, the Cambridgeshire Mammal Group and the…

Since May last year volunteers have been monitoring Cherry Hinton Brook’s River fly larvae populations. Riverflies are an important indicator of the overall health of a water system.

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…

Working firstly at Barnwell East pond, as this is one of the city’s most important common toad breeding sites, the volunteers removed overhanging willow and created a large hibernaculum. CPARG are planning to survey the site this coming spring to get an idea of toad numbers. Next to receive some attention were the ephemeral ponds located at the back of Stourbridge Common. The Friends of Stourbridge…
