/ Wind farms "driving rare birds and bats to extinction"
Hmmm, so they're saying that every other day or so every wind turbine kills a bird. Three a week, a dozen a month, 150 a year or so.
Why have I never seen dozens of dead birds beneath a wind turbine? Am I just not looking closely enough? Are they all eaten by foxes before anyone notices?
Fraser Nelson, The Spectator, Conservatives, windfarms....
which hardly suggests a impartial approach from the Spectator.
Stupid post. They guy is an experienced professional in this area. Either you pay some attention to that or to a right wing rag with an agenda.
a year old report and looking at the other top 10 or so google links relating to it they all have "may" or "could" with the methodology being unclear.
Be a lot of bodies for ring ouzel and co to find, unless they are being hidden/eaten quick.
> to that or to a right wing rag with an agenda.
The piece was written by: "Im a lecturer in biological and human sciences at Oxford university. I trained as a zoologist, Ive worked as an environmental consultant conducting impact assessments on projects like the Folkestone-to-London rail link and I now teach ecology and conservation."
Yet instead of regarding his piece as by "an experienced professional in this area" you discount it as "a right wing rag with an agenda".
I can't be bothered arguing with you.
Maybe he is right but he is not doing a very good job of making his case if so.
I've tried to find the original SEO/Birdlife report. None of the links in any of the reports I've read work.
Wind farms are not the whole answer, they are only a very small part of the solution but they are necessary. Other things are also needed (I think thorium nuclear should be part of it) but they will take longer to develop.
Of course he might have published this in the Spectator because no other paper would run it because they want to hide some facts, or he might have published this in the spectator because he knew they wouldn't question his facts?
A big flaw of most mainstream newspapers and magazines is that they don't give references. Many newer methods of dissemination, such as blogs, can be much better at this (despite often being regarded as less authoritative).
Though elsewhere in the article the term is used without inverted commas. In that instance with inverted commas he seems to be making the point that, on long time-scales, the climate is always changing.
He does seem to have published on birds and other animals. See http://www.sciencedaily.com/releases/2010/10/101011161639.htm regarding his paper "Hambler, C., Henderson, P. A., Speight, M. R. (2011). Extinction rates, extinction-prone habitats, and indicator groups in Britain and at larger scales. Biological Conservation, 144, 713721.
For those commenting on this author's ideological stance, note his quotes at the bottom of that piece: "Many ancient and important habitats in Britain are threatened today because of human activity and population growth -- whether it's an increase in water use, growing use of wood fuel, or the growth of urban sprawl. Despite conservationists' efforts it's very likely extinction rates will continue to rise in Britain and globally for many years. These losses will impact on human welfare, and I'd say conservation needs a profile and resources even bigger than climate change."
And: "This work strengthens the claim that the world is suffering a mass extinction. We can now be much more confident that across the planet the less conspicuous and less well-known species are going extinct at a similar high rate to that already witnessed in birds, fish and amphibians."
Hello, fellow ecologist here. I didnt read the article linked to but I attended the IEEM conference (did you?, apologies if so, you will know the next bit) in respect of renewable technogy, since I was hoping to get early news of the outcome of DEFRAs research on the impact of tubines upon bats in the UK. Those undertaking the research are not yet willing to commit to conclusions but did highlight some interesting stuff - I think Ive remembered this correctly:
Bat corpses disappear within a couple of days, max. Mostly pulled down and gobbled by beetles.
Human searchers for bat corpses around a turbine turn up only 20% of bats that are present, trained dogs find 70%. Humans also take 2.5 hours to search a 100m radius, dogs take 40 minutes.
I wont waffle on, but basically there are a bunch of people in the UK trying to build an evidence base upon which more informed decisions can be made in future.
Lastly, ring ouzel, Im envious of your turbine controlling power! Is your role at that site enshrined in a S75/S106 or similar?
I can only imagine this figure can be arrived at by strewing an area with a known number of bat corpses! How else would you know? And if that were the case, how would it prove how many actual bats get hit by actual turbines? I'm not meaning to be controversial, just wondering if the conference mentioned the methodology in arriving at those numbers.
You guessed right! :)
The first thing to do before searching for corpses at turbines was to find out how effective searching for corpses is in the first place. Bat corpses were strewn about beneath turbines and the relocation rate obtained.
It goes no way to proving/disproving anything about bat mortality and turbines. All it does show is that if you give a trained dog or trained person that amount of time at a turbine, the number of bats they find would be a given proportion of the number likely to be present.
Ask the dog.
If you dont know, you cant have them :-)
There is an army of Licensed batworkers across the UK who usally all have one or two knocking about somewhere, waiting for identification. Handfuls more get found every year, and/or sent in for rabies testing, or dried out and flattened and kept as reference specimens. Need a Licence though, otherwise its illegal to keep dead bits of bats.
