Climate Change is not the Greatest Threat to Wildlife

 

The main threats today to the survival of orangutans  :

• Loss of habitat through deforestation

• Palm oil plantations

• Illegal hunting

• Illegal pet trade

At this rate of loss, many experts believe orangutans could be extinct in the wild in less than 50 years.

As you know, the vaquita is on the edge of extinction and, unless action is taken now, the species will be lost within a few months or years during your administration. No more than 22 vaquitas remained alive during the summer of 2018, prior to the current fishing season. Each year, half of the remaining vaquitas are killed in illegal fishing nets set for another endangered species, the totoaba. Poachers prize totoaba for their swim bladders, which are dried and smuggled by organized crime cartels to China, where they are sold on the black market for prices that can reach $46,000 USD per kg. The acoustic monitoring program indicates that the few remaining vaquitas inhabit a very small area, approximately 24 x 12 km, most of which lies within the Vaquita Refuge. However, high levels of illegal fishing for totoaba occur in this area.

Climate change is used as cover by the global trade industry to justify their destruction of wildlife.  Whilst environmentalists were crying about carbon emissions, the global trade industry quietly went about their business of wiping out endangered wildlife.

Decarbonisation Means Job Losses

This week, two myths about renewables were exploded. First, Bord na Mona, announced that there would be job losses as they moved away from peat harvesting and changed their focus to renewables. Trade Union leaders have estimated that the job losses could be anywhere between 300 and 850 in the next decade. 

Unite regional officer Ed Thompson said decarbonisation will result in further job losses.

Back in 2015, the Government were announcing wide scale job creation in their renewable energy White Paper :

 And we are committed to supporting businesses, workers and communities to make the transition away from older energy technologies – in the direction of new jobs, new technologies, and new opportunities.

Our energy transition will present further opportunities for job creation and economic growth. For example, it has been estimated that measures required to meet our 2020 renewable energy targets could deliver between 2,500 and 5,550 jobs in the bioenergy sector and up to 4,000 in onshore wind deployment

The media lapped this up at the time. But now reality is hitting home. I for one, am in favor of moving away from peat but the only viable job creating and sustainable alternative is fracking or offshore exploration. The Corrib natural gas field created 1,000 jobs during development. 



The other myth that was exploded this week was that wind farms are not damaging to wildlife. A UCC study that even RTE reported on showed that

Irish bird populations decrease in the areas immediately adjacent to wind turbines.The study found that the main reason appears to be the clearing of habitats during the construction of the wind farms.

Impact of Wind Turbines on Birds of Prey in Ireland

An Irish Buzzard

Three years ago (2011) a sea eagle died after colliding with a blade at a wind farm at Sillerthane, near Kilgarvan - Irish Times 2014.

“Shooting is not the biggest problem, poisoning has killed the most and three have flown into wind turbines - White Tailed Eagle reintroduction project manager Dr Allan Mee (2014)”

Evidence for bird of prey collisions with wind turbines is small - about six or seven in the past few years, most notably from tagged eagles that have been re-introduced into Ireland from Norway. This makes it easy to track and record deaths of these birds. However, deaths of native birds of prey e.g. buzzards and falcons are more difficult to track as most, if not all, go unreported. And as any farmer will tell you, a dead bird will be picked up by a scavenger within hours.

There have only been three studies carried out into Wind Turbine bird fatalities in Ireland. They were all carried out at Lisheen Wind Farm and have been obtained under Freedom of Information.

In 2010, two sparrowhawks carcasses were found shortly after operation of the wind turbines. In 2012, a carcass of a kestrel and a buzzard were found beside a wind turbine. Other dead birds were also found such as crows, gulls and pigeons. Only two dead crows were found and no birds of prey during 2013/14 searches. This tends to show that most bird kills occur during the first couple of years of operation. However, many more studies would be required to establish enough evidence to form a proper conclusion.

The Lisheen studies conclude with a very important statement :

"most studies rely on the number of carcasses found, but this can be extremely unreliable, since it is known that carcasses are quickly removed by predators"

So we really do not know the full impact of wind turbines on birds of prey. Green advocates will argue that cars and pets kill more birds. But they fail to discern between birds of prey and common birds. Pets are incapable of killing larger and rarer birds. Cars have been known to kill large birds, in particular low flying owls, but to a much lesser extent buzzards and eagles. The Lisheen study makes this distinction clear :

Species that are long lived and have low productivity (such as many birds of prey) are at higher risk of population level impact through individual losses than short lived and highly productive bird species.

So there is no danger to gull or crow populations from wind turbines but there is a significant threat to birds of prey. A worrying development is that An Bord Pleanala don't seem to consider the threat to protected wild birds much of an issue and have even ignored their own inspectors, for example in the case of a wind farm in Roscommon which was eventually refused permission after a High Court challenge by local man, Ted Kelly:

Mr Kelly also alleged the Board failed to specify exactly why it approved permission for the developments when two of its own inspectors recommended permission be refused after appeal hearings. The inspectors concerns included the visual impact of the developments and their impact on birds and habitats of conservation. He claimed the development of 16 turbines at Croan is likely to impact on ten sites of conservation importance in south Roscommon, including three nature 2000 sites at Lough Croan, Four Road Turlough and the River Suck Callows, with particular concern expressed about the impact on Whooper Swans, Greenland White-Fronted Geese and Golden Plover. The second development would adversely impact on both bird and bat species, it was alleged.

There is also the habitat impact. For example, Carrickaduff wind farm in Donegal requires 121 hectares of deforestation. This impacts other bird species and bats.

The problem for bird of prey numbers is that many wind farms are built in high areas with high winds - the same areas most bird of prey species occupy. The Bird Societies in Ireland seem to think that wind farms and birds of prey are compatible but I see no evidence for how this could be. The wind industry certainly don't care about birds as can be seen in some of their planning applications for wind farms in areas of special interest.  It is left then to local objectors and true bird enthusiasts to defend these majestic animals from this new attack on their existence.
