It’s good to see that the gardens are such a good habitat for them. It goes to show that the gardens are full of life, as voles typically thrive on small plants and they can live on almost any nut or fruit.
The gardeners may be less impressed however, as these innocent looking visitors eat away bulbs in the ground. They create excellent burrowing and tunnelling systems and these give them access to sensitive areas without warning.
They do have big benefits for the gardens too however. Like other burrowing rodents, they also play beneficial roles, including dispersing nutrients throughout the upper soil layers. So seeing them thriving here is a sign of good, sustained growth in the gardens.
