Tern Rafts

Specifically designed to meet all nesting requirements of island-nesting Terns (especially the Common Tern). The Eco Tern Raft is made from fibreboard sandwiching a buoyancy layer of polystyrene.

Each GFB Tern Raft is 8ft (2.4m) by 4ft (1.2) and is very robustly built to withstand the constant buffeting of wind and water. The manufacture of our Tern rafts has evolved over the past four years, because of the confidence in our build quality and the materials we guarantee each one for ten years. An individual raft can be anchored as single nesting platform or multiple rafts can be simply bolted together to create much larger nesting islands.

GFB Tern Nesting Rafts are made from a high density polystyrene flotation block, a tough tubular nylon section frame, completely encapsulated by water resistant fibreboard (MSF) and finished with a fibre-glass outer shell.

We offer our rafts with or without predator (Mink) proofing, but we strongly recommend the clear polycarbonate side panels which prevent access by predators from the water onto the nesting platforms. Although not scientifically proven, from conversations with nature reserve wardens it has been suggested that the predator proofing may also provide additional shelter during periods of strong winds and driving rain.

Tern Rafts are delivered to site by members of the GFB team who will offer assistance, advice and will be happy to be involved with the launching of the rafts if requested.

Most of our rafts have been installed on lakes, pool and reservoirs many at nature reserves and aimed at providing nesting islands mostly for Common Terns. After spending the winter in Africa our Terns return back with us from mid April and start to settle down to breed by May. One of the problems they encounter on their return is that Gulls, particularly Black-headed are already breeding and have taken all the available nesting sites. To avoid this reserve wardens often wait and refloat the rafts after the B-h Gulls have laid their eggs, alternatively GFB Rafts can be fitted with temporary netting leaving the rafts free and available exclusively for Terns.

We at GFB have researched into the most suitable design and the best materials for our Tern Rafts, bobbing around in the middle of a windswept lake and we borrowed some features and ideas used in the manufacture of water ski jumps. Whether a single raft or multiple nesting islands we are confident we can deliver exactly the right nesting platform for any water body or nature reserve and create the optimum nesting opportunity.
