Ridlins Mire is a 1.6hectare nature reserve managed by the Herts and Middlesex Wildlife Trust in Stevenage, Hertfordshire, England.[1]
This wetland site is a type of peat bog. It is the result of a spring, which has resulted in the growth of peat over many years into a domed structure called a rheotrophic hangmire. This is a rare habitat and unique in Hertfordshire.[2] The dominant plants are tussock sedge and marsh marigold. There are birds such as long-tailed tits and great tits, and butterflies including large whites and small tortoiseshells.[1]
The site is unfenced on its border with Goddard End, but access is difficult as there is no formal entrance or footpaths.
