This major predator fence project was completed for an important RSPB site on wetland ground. Much of the fence runs through reeds and standing water, making installation especially complex. At over 3000 metres long, this fence forms a complete enclosure to protect vulnerable wildlife while remaining discreet in appearance once vegetation regrows.
Engineered for Waterlogged Terrain
Deltapost System with 30-Year Warranty
The fence was constructed using our Deltapost system - specially designed for soft, wet ground. With a buried return fold and cranked netting above, the final fence stands over 2.2 metres high. Only one of the 61 strainer points required an external brace, which was predator-proofed using a rolling sleeve to prevent climbing.
- Over 3000m of predator-proof fencing installed
- Buried base fold and cranked top for full coverage
- 30-year lifespan Deltapost system
- Fence height: just over 2.2 metres
- Reedbed location carefully flailed for access
Crossings and Finishing Touches
Weirs, Ditches and Precision Gating
The fence includes two weir crossings, three ditch crossings, and multiple vehicle and pedestrian gates. Every gap within the 8500mē enclosed area is under 80mm wide, meeting stringent RSPB predator-exclusion criteria. This groundbreaking fence system was designed collaboratively and executed without major surprises.
- Crossings: 2 weirs and 3 ditches
- Multiple gates: pedestrian and vehicle access
- No holes larger than approx. 80mm across the boundary
- Installed late 2019 without major disruption
- First system of its kind combining Deltapost and water crossings
