The 20cm Bio Vole Guard is a short, biodegradable tree guard engineered to protect newly planted whips and young trees from bark-stripping by voles and small rodents. Measuring just 20cm in height, it focuses on shielding the most vulnerable section of the stem—where vole damage is most likely to occur—making it ideal for use in woodland fringes, rural boundaries, hedgerows, and farmland shelterbelts.

Manufactured entirely from plant-based biodegradable polymers, this eco-friendly vole guard naturally breaks down over 3–5 years into water, CO₂, and biomass—removing the need for manual collection or waste handling. Its split-tube design allows for quick, tool-free installation and accommodates natural stem expansion without girdling, while maintaining ventilation and access to light.

Whether you’re a farmer restoring field margins, a forestry contractor delivering biodiversity net gain, or a landowner safeguarding trees on vole-prone land, the Bio Vole Guard offers a sustainable, low-maintenance solution.
