THE Scottish Government has been ridiculed after plans emerged to shoot lasers at seabirds to work out how high they are flying.
Ministers are tendering for the use of a sophisticated laser radar system – costing in the region of £250,000 – and capable of measuring the height of birds to a few centimetres.
The information will be used to help work out the height and placement of offshore wind turbines to try to reduce seabird casualties.
But the plan, estimated to cost £1,000-a-day, has been condemned as “boondoggle” and a “flight of fancy” by taxpayers’ groups who said the money would be better spent on badly-needed public services.
The system, called Lidar, works in a similar way to radar but instead of using radio waves it measures the amount of laser light that bounces back from a target.
The technology was first used by Apollo 15 astronauts to map the surface of the moon.
The system fires six million laser pulses per second at the unsuspecting Scottish seabird. By measuring how long the light takes to return the bird’s height can be worked out.
The bid document is entitled: “Estimating Seabird Flight Heights using LiDAR”.
It states: “The Scottish Ministers wish to engage a contractor to undertake a research project entitled ‘Estimating seabird flight heights using LiDAR’.
A spokeswoman for the Scottish Government said: “This project is part of ongoing research to improve the scientific base for environmental impact assessments of offshore wind turbines.
“We support the development of renewable energy in Scotland but will always act to ensure this is done with as little impact on the surrounding environment as possible.”
Andrew Baker – head of surveying firm Baker Consultants – said that lidar is accurate to within 3cm.
He explained: “It enables you to create a 3D model of whatever you’re interested in extremely quickly and extremely accurately.”
But he estimated that the cost would be high as the project would likely require a survey boat, which “could cost £1,000 a day easily”.
The lidar device itself, he said, could cost around £250,000 but it is likely that the company taking on the contract will already own this.
Eben Wilson, head of Taxpayer Scotland, hit out at the cost, saying: “Isn’t it wonderful how the state can be persuaded to use our hard-earned tax on arcane pursuits – flights of fancy even.
“Once momentum is gathered on nice-to-have research there is no end to what some will say is useful to know.
“Where are our priorities? Adding perfect analysis through boondoggle projects, or helping the vulnerable. We cannot afford to do it all.”
A spokeswoman for RSPB Scotland defended the project, saying it “should help ensure that offshore wind farms can be developed in locations which do not threaten Scotland’s internationally important seabird populations.”
In 2014 the government said it was examining the use of lasers and drones in a bid to rid Islay of its geese.
Farmers on the island complained that the birds acted like “a swarm of locusts”, causing irreparable damage to their £11m a year industry.
Self-launching kites, helium balloons, fireworks and a gas-inflated, siren-blazing ‘scary man’ mannequin were also used in the elaborate attempt to ward off the 50,000 geese.
