N.S. approves wind farm, but federal officials worry project would kill at-risk birds – Halifax | 24CA News
A 13-turbine wind farm not too long ago authorized by the Nova Scotia authorities is worrying federal officers, who say there isn’t sufficient details about what affect the mission may have on the endangered roseate tern and different birds.
Nova Scotia’s Environment Department authorized the Wedgeport Wind Farm, on the province’s southwest coast, on May 4. Also on that day, an atmosphere evaluation by Environment Canada and the Canadian Wildlife Service grew to become public.
The federal businesses be aware of their report that 75 per cent of the breeding of the roseate tern inhabitants in Canada happens about 15 kilometres from the proposed wind farm. They say the endangered animals “may be vulnerable” to the generators as they fly throughout the mission space at Little River Harbour, N.S., searching for meals.
The seabirds have a particular look, with black caps, payments which are pink at their base and a forked tail. The Canadian Wildlife Service has reported that their numbers have plunged to the purpose the place the species is taken into account in danger.

There are worries concerning the potential impact a 13-turbine wind farm could have on the endangered roseate tern and different birds, because the province offers a inexperienced gentle to the Nova Scotia mission.

Federal officers additionally report considerations about different birds, noting that the realm’s headland — a slender piece of land that juts out into the water — is house to “known important bird habitats” and is used for resting, refuelling and overwintering. They say shorebirds and geese transfer over the realm at an altitude that places them susceptible to collision with the generators, particularly at nightfall and daybreak.
The federal consultants say there’s inadequate data to evaluate the mission’s impacts on birds, and so they name for the creation of maps detailing the flight paths of the varied species, which might reveal whether or not they’re susceptible to collisions with generators.
John Kearney, an environmental researcher who has used acoustic strategies to chart the excessive densities of hen calls within the Little River Harbour space, says he was disillusioned the Progressive Conservative authorities authorized the wind mission.
He mentioned in an interview on Monday he stays involved concerning the birds dying from exhaustion in an effort to avoid the massive windmills — or by blunt pressure trauma in the event that they fly into them.
“Environment Canada is stating, ‘There are migratory birds’ and ‘You need to map them,’” he mentioned. “And once they do that, they will have to show they are taking measures to prevent damage and death as (the birds) pass through the corridor.”

Daniel Eaton with Vancouver-based Elementary Energy — the corporate growing the wind mission — wouldn’t touch upon the particular observations from the federal businesses within the atmosphere evaluation his agency commissioned.
In an e-mail, he mentioned the province has laid out situations for the mission, together with that research be produced on the sorts of birds that dwell within the space, which he mentioned would inform future conservation measures. The province has additionally required the corporate to provide a two-year examine on hen and bat mortality attributable to the generators.
“We anticipated receiving approval conditions for the Wedgeport Wind Farm Project environment assessment, which are generally consistent with other wind farm approvals in Nova Scotia and across Canada,” he wrote.
The firm has beforehand acknowledged that by 2025 — the potential first yr of operation — the mission is anticipated to offset 112,750 tonnes of carbon emissions, roughly equal to the yearly output of 25,000 gasoline-powered vehicles.
The firm’s area survey recognized 100 hen species inside and out of doors the mission space, and about 16,000 particular person birds.
Elementary Energy additionally predicted that the mission would result in about 36 hen deaths a yr, citing a mannequin developed in 2016 from Scottish Natural Heritage, an environmental advisory physique.
However, Kearney and the Nova Scotia Bird Society have been crucial of that mannequin. Kearney and the society have mentioned his acoustic information offers sturdy, comparative proof that the proposed farm is in the course of a migration hall.
The federal division declined to offer one of many consultants for an interview, or additional remark.
