They’re wildlife verges:
Wildlife verges
We have selected verges across the county known as wildlife verges, which have been identified as having wildlife of particular interest. Roadside verges can provide a habitat for many rare species of wildflowers and mammals, which need to be protected.
To help maintain these habitats we make sure that we do not normally cut our Wildlife verges between 1 March and 31 August. This allows for the wildflowers to seed.
The wildlife verges are marked with small yellow indicators. These help our grass cutting team to identify them correctly.
