  • Saying No to dirty coal

    Zoe Clelland, RSPB Scotland Senior Conservation Officer, gives us an update on objections to the proposed coal fired powerstation at Hunterston on the Ayrshire coast.

    Saying NO to dirty coal

    The proposal by Ayrshire Power Limited (APL) to build a new coal fired powerstation at Hunterston on the Ayrshire coast has been an important piece of work for us for three years now.  The proposals have horrified many people who know the area as a really important site for wildlife – its pretty much a unique piece of mud and sandflat in an otherwise rocky coastline.  This makes it especially important for birds stopping to feed on long journeys between breeding and wintering areas or for those that spend the whole winter in Scotland. Its not only RSPB who thinks so, Scottish Natural Heritage designated this as a nationally important site in 1971 but despite this, the area is now under serious threat.

     

     The area's mudflat and seagrass beds support large numbers of wintering birds including redshank.

    APL want to fill in over 30 ha of the site to build a new power station, completely destroying the mudflats underneath in the process.  When you combine that with lots more activity in the area, pumping of artificiallywarmed water back into the Clyde and the use of chemicals to stop marine life living in the cooling water system, its easy to see why this will be so damaging and why RSPB is working hard to make sure the right decision is taken to refuse this application.  On top of that, this power station will burn lots of new coal and result in a big increase in carbon dioxide emissions.  Given everything we are trying to achieve in Scotland to reduce the impacts of climate change, this would definitely be a retrograde step.

     

    This week I’m working on RSPB’s response to an addendum to the powerstation application.  APL had to do produce this to answer a lot of difficult questions that weren’t answered by their original application last August.  The addendum certainly contains a lot more information but it does nothing to allay our concerns and in fact it raises more. 

     

    RSPB experts on planning, energy and water have all contributed to this response because we want to make sure that all aspects of this application are scrutinised carefully but of course the fundamental question is a simple one.  Does the Scottish Government really want to consent a development that will damage Scotland’s environment now by building on one of our nationally important wildlife sites and for decades to come by contributing to climate change?  It seems a straightforward question but to make sure the right decisions is made, please object to the development – to find out how, go to www.rspb.org.uk/hunterston.

  • From sea to shining sea

    If you’re fortunate enough to work for the RSPB, you get the opportunity every seven years to take a well-earned sabbatical of up to four weeks. You can go and work on another conservation project at home or sometimes abroad, usually with Birdlife International. Or you can design your own sabbatical but it must meet strict criteria. It’s a very worthwhile employment benefit which helps to refocus and refresh valued staff. RSPB Scotland Mull Officer Dave Sexton has just returned from his third sabbatical with the Society…but this time it took a dose of winter ‘man-flu’ to get him started…

    From sea to shining sea

    It came to me on my sick bed. There I was on a particularly dreich winter’s day in January, propped up in bed with a mug of steaming hot Lemsip Max All in One, aching from head to foot and feeling very sorry for myself. My sabbatical had been due since last August and I’d done nothing about it. There just never seemed to be enough time to organise things, never a good time to be away from Mull, we couldn’t afford it anyway, blah blah blah.

    My feverish, drug-filled mind then started to wander in an aimless kind of way – thinking of nice sunny places around the world with lots of birds - one good way to start the sabbatical planning process I’ve often found. Slowly, as the medication got to work, a germ of an idea started to take hold. With my current work revolving around the reintroduction of white-tailed eagles in Scotland, what about seeking out a selection of other endangered species recovery projects to evaluate their success – or otherwise? I could revisit some of the other bird of prey projects I’ve been involved with over the years – like bald eagles, ospreys, peregrines and California condors? Ah yes, California. That’s it! How did that old Beach Boys song go again? “The west coast has the sunshine and the girls all get so tanned…” I don’t know what they put in Lemsip these days but I was suddenly feeling much better.

    And so, a sick day in bed was put to very good use. By the end of the day, my outline plan was gathering pace. We’d go into Washington, DC, be based in Annapolis, Maryland on the east coast to work with the US Fish & Wildlife Service on their osprey monitoring programme in the Chesapeake Bay; then head down to Virginia to my old university at the College of William and Mary in Williamsburg where they’re working on bald eagle population dynamics and peregrine falcon reintroductions; and then start the long journey west, first to Arizona to catch up on how the California condor reintroduction project is faring since my first sabbatical there with the Peregrine Fund in 1997. Finally to the Pacific coast and California where it all began (and very nearly ended) for the condors in the 1980s when the final few wild birds were all taken into captivity to begin a bold captive breeding programme. And that’s pretty much how my sabbatical panned out seven months later…

    I initially spent time in a not-very-exotic location. I was with the US Geological Survey and Fish & Wildlife Service who were taking blood samples from fledgling ospreys amidst the industrial landscape of Baltimore Harbour and the Patapsco River. They’re using the well-recovered osprey population (which nest on cement works, sewage treatment works, pylons, cranes – you name it), to monitor the health of the bay. It was inspiring to see the ospreys apparently thriving in that environment when we still tend to associate them here with remote Scottish lochs, glens and Scots pines!

    Then it was on to the train south and into the sweltering 100 degree + heat and humidity of southern Virginia. Here I re-visited the long-running bald eagle recovery project on the James and York Rivers which are now almost at ‘ESP’ (Eagle Saturation Point). An incredible recovery (spear-headed by the team at the Center for Conservation Biology who I spent some time with) from a low of just 30 pairs in the 1970s to a staggering 730 pairs today. Now that’s what I call a successful species recovery project! I wonder how their close cousins, the white-tailed eagles, will now fare over a similar time frame in the UK?

    The descendants of the peregrine falcons which I’d helped to reintroduce to the eastern shore of Virginia in 1981 were also thriving. Many are still nesting on man-made structures like ‘hack’ towers, bridges and buildings whilst others are now colonising natural, ancestral cliff sites in the Blue Ridge Mountains. So far so good. It was all mostly good news! Quite heartening really when we hear so much about the bad news and problems many of our big predators are facing at home and around the world.  Not that it’s all plain sailing.

    The condors in Arizona and California are doing well too but progress sometimes seems painfully slow and the project continues to be hampered by toxic lead in the environment. The condors scavenge on hunted deer and coyote carcasses and ingest lead fragments from the bullets. The Peregrine Fund and State Game and Wildlife agencies are working with hunters and ranchers to persuade them to switch from lead to copper bullets. It’s getting there – up to 70% compliance in both AZ and CA . For the field crews in both states, it’s tough and gruelling work when you have to re-trap all the released and wild bred condors at  intervals to flush the lead out of their systems.

    It was quite a moment for me to see an active condor nest cave. When I last worked on that project, it was only a year after the first captive-bred condor releases and successful breeding seemed a very long way off. This year’s chick stayed well hidden inside the deep cave but it was enough to know it was in there - somewhere. One local nest cave which is in use again after tens of thousands of years without condors revealed the bones of a prehistoric condor – this Canyon Country is timeless. And then to watch an adult condor soaring over the North Rim of the Grand Canyon – well, it simply takes your breath away. For once, the word ‘awesome’ summed it all up.

    But it was the visit to Yellowstone National Park in Wyoming and Montana that provided the biggest surprise of the sabbatical. My target species there has been the focus of one of the most famous and controversial reintroduction projects in the history of wildlife conservation. OK, they’re not birds of prey, not even birds. I knew it would be interesting to visit this project on the ground but had no idea it would end up being even more relevant to my work back home than the raptor-related projects I’d visited so far.

    Wolves bring out the best - and worst - in human nature. Grey (or timber) wolves were, like white-tailed eagles, persecuted relentlessly across their range. They became extinct in most states. At one point even the Government had a policy of eradicating them from Yellowstone itself! How times change. In 1995 and 1996, wolves from Canada were caught, tranquilised, transported, acclimatised and eventually released into Yellowstone. The top predator was back and the whole eco-system started to come back into balance: elk numbers dropped, aspen recovered, beavers returned to the rivers, more ponds were created, more wildfowl arrived, more invertebrates…the circle of life.

    Despite huge opposition there was also huge support; the project went ahead and has gone from strength to strength. There are now 12 wolf packs in Yellowstone. So much of the US wolf saga mirrors the UK white-tailed eagle story both in historical terms and even some of the ongoing arguments today.

    But just as we’ve found on Mull, one of the big bonuses of these projects has been the increase in wildlife tourism. Wolf and eagle watchers are, by and large, very similar folks. They spend locally, they return over and over and they usually behave! Both eagles and wolves bring in millions of £ and $ to their local economies.

    I spent time in Yellowstone with US NPS rangers, workers on the Wolf Project and countless volunteers who give up weeks, if not months, of their year spotting, observing, radio tracking and helping visitors find wolves. I was struck by just how willing and patient they all were in dealing with the thousands of visitors – Yellowstone had an eye-watering 900,000 visitors in July alone. I’m very glad we were some of them. Here’s a taste of one fine morning in Yellowstone…

    As usual, we began the day just before dawn. The scent of sage and pine filled the chilly air. We joined US NPS and Wolf Project workers Rick McIntyre and Doug McLaughlin as they located the famous Lamar Canyon wolf pack – probably the most watched and studied wolves in the world.

    As the early morning mists rose from the Lamar River, the alpha female of the Lamar Canyon wolf pack launched her attack on a powerful cow elk. Other pack members soon raced alongside and bit at the elk’s legs as she galloped at full speed towards the river. Her head held high in blind panic, eyes wide and staring, nostrils flaring, the elk kicked out with her front hooves. She struck the lead wolf - an inexperienced black yearling – painfully in the jaw. One after the other, the elk and wolves crashed down the river bank and into the fast flowing river.

    The wolves swam as they were quickly out of their depth while the elk found the deepest part of the river and stood her ground – just. With the foaming, ice-cold melt waters threatening to knock her over at any moment, the wolves knew they’d been beaten – this time. They sat panting for a while on the river bank, watching her watching them, playing the waiting game. For a while, they looked like they had all the time in the world. But they didn’t. They had five hungry pups back at the den on Round Prairie and they knew they had to hunt again and deliver food today. Eventually, after a tense stand-off, the pack started to disperse, led as ever by the alpha male and female. Their grey and black forms melted into the shadows of the aspen grove, there were one or two brief howls and then they were gone.

    All this happened about 300m away from where we stood. My two young daughters who only minutes earlier had been huddled disconsolate and shivering in the pre-dawn chill, were now wide awake and staring spellbound at the dramatic, wild scene that had been played out before them. It’s a sight none of us will ever forget.

    As the wolves vanished, so too did many of the exhilarated wolf watchers. We thanked Rick and Doug for all their help and we headed off for a celebratory breakfast of coffee, pancakes, syrup, eggs (over-easy) and bacon at Roosevelt Lodge. Then it was back on the road again (historic Route 66) and on to the next phase of this amazing adventure. Finally to California and the stunning but foggy Big Sur coast with its giant redwoods – ancestral home to the last of the wild condors.

    And so the sabbatical concluded. Where did those four weeks go? There are lifetime memories to treasure, old acquaintances renewed and new contacts made, many lessons learned for a re-energised and fresh look at work back home. But most of all, just a celebration of all the successful reintroduction projects which colleagues from other wildlife agencies and the RSPB have been part of over many years. Righting some of the wrongs of the past.
