Water Vole Fencing

Herpetosure water vole fencing is a cost-effective, durable exclusion barrier used in ecological mitigation to keep water voles away from development sites, watercourses and containment areas. Made from recycled polypropylene panels, it has been specified by developers, contractors and conservation bodies, including the RSPB, on projects where water vole populations need to be protected during works.

Fencing specifications

• Herpetosure Water Vole Fencing: 1700 X 1500 X 3mm
• Herpetosure Water Vole Fencing HD: 1700 X 1500 X 6mm, light green recycled polypropylene panels

Fitted measurements

500mm vertically below ground, 1200mm vertically above ground, supported with timber stakes.

Fitting explanation

Installers fit the panels into a 500 x 50mm slit cut with a V backed sub soiler or “wiz” plough towed behind a tractor, or into a trench dug with a chain trencher, mini digger, or by hand where access is tight. Slitting gives the best result and the fastest fit where ground conditions allow it.

Once the panels are in place, closing the slit is a matter of driving back along the fence line with a tractor or vehicle, or compacting it by hand. This seals the panel against the soil on the side nearest the vole population, or the inside face if the fence forms a containment area.

Panels overlap by 50mm and are joined with aluminium blind rivets, then supported on timber stakes. They can be cut down, or the overlap increased, to follow uneven ground or contours. Where a ditch or watercourse crosses the line, fine weld mesh keeps water moving through the barrier without letting voles pass.
