Sunset

Many thanks to Sue Cameron for this picture of last night's sunset, taken from Ardnamurchan's north coast looking towards Muck andRum.

32 Degrees

The bay below our house is a wonderful place to swim on a day when temperatures soared towards new records, but there are....

....creatures lurking in the depths which have to be avoided - not that moon jellyfish have a nasty sting, though encountering one isn't pleasant.  So the Diary is sent out....

....in a kayak to scout the waters for any real nasties, like a lion's mane jellyfish, of which there are a few around this year.  But, once the bay has been declared safe for swimming, a paddle along the coast sometimes yields useful flotsam, like a fish box washed up in a bay which will go up into the vegetable garden.

Clearing the Archaeology at Camas nan Geall

A group of volunteers, some from Ardnamurchan but others from as far away as the Uists, joined Phil Richardson and Paul Murtagh of Archaeology Scotland and Sarah Ashford from Adopt-a-Monument to spend the day clearing the bracken, nettles, grass and other cover from the two main monuments at Camas nan Geall - the neolithic chambered cairn and the graveyard.  Picture shows Phil briefing us before we started, when the temperature was, at least, reasonable.

Paul was happy to demonstrate the scale of the task.  As can be seen, the bracken in the graveyard was well over head high and almost as high as the Bronze Age standing stone behind Paul.

Not that the scale of the vegetation, nor the steadily rising temperature were enough to dampen the enthusiasm of those taking part.  This is the graveyard at a point late in the morning when it had been largely cleared.  Note that Archaeology Scotland even provided drinks and biscuits.  Nor are....

....Archaeology Scotland the sort to expect nothing but hard labour from its volunteers.  Picture shows Phil and Paul teaching Wendy and Dave how to survey the rapidly emerging chambered cairn.

As the temperature soared towards its day's maximum of 32C.... yes, 32C....  the group was able to stand back and admire the results of its efforts.  The two complete Campbell gravestones, dating to the first part of the 18th century, are now clearly visible, along with a third, just to the right of them, broken and lying on its side, which....

....we'd never looked at closely before.  It has a number of carvings on it, but one is a skull with three crossed bones, and what looks like a larger bone beside it.

There's a huge amount of work to be done on the archaeology in the graveyard, so we're hoping that we'll be doing some 3-D digital survey work on it between 8th and 10th August; if anyone would like to join us, please contact Phil at p.richardson@archaeologyscotland.org.uk.

We're well aware that merely clearing the two sites in the middle of summer isn't enough.  The area needs proper management so that visitors and archaeologists can have good access to this historic site at all times so, with that in mind, we'll be talking to Phil and to the Ardnamurchan Estate, who were kind enough to allow us access, about how this can be achieved.

Many thanks to the hard-working team that came along - Jenny and Dave Kime, Jim Caldwell with his strimmer (which, understandably, overheated), Wendy Macfadyen, Mairi Stewart and Catherine MacLeod from the Uists, and Allyson and Andrew Perkins.

Ardnamurchan Black Bee Project Update

Progress in 2013

Early last year we were offered support and, once we were ready, Amm stock from Andrew Abraham on Colonsay. This helped us create our plans for an Arnamurchan Black Bee Project with greater confidence, encouraged also by BIBBA’s generosity in supporting the start-up with £1500 funding from Project Discovery.

Last year we concentrated on improving our queen-rearing skills and put to good use the mini-nucs bought and funded by BIBBA. Each of these was used, some of them for two cycles of queen mating, working with our existing local bees which are some 45-80% Amm.

Sadly the SBA/BIBBA queen-rearing course planned for June was cancelled because of the late, cold Spring so we had to rely on guidance from books, the SBAi forum and experienced beekeeping known to us.

We were new to grafting and had some success with acceptance of larvae (50%+). We also used the Cupkit system which gave more reliable acceptance but we recognise that, with the black bees in future years, this system will be less appropriate as we will wish to breed from all the queens we have, rather than rear many queens from one or two queens.

Mating was also reasonably successful: about 80%, though we have since found that a few of those queens were not well mated (the weather was very mixed) and their colonies failed in the Spring.

Apiary sites

Last year Ardnamurchan Estate kindly offered us a selection of apiary sites at and around Glenborrodale, approximately half way down the Ardnamurchan Peninsular and some 8.5 miles from the nearest managed honey bee colonies. The area was chosen for its absence of managed local hybridised bees and good forage. A wild colony survives in woods some 3 miles from Glenborrodale and these bees look black though their genetics are yet to be tested (see below re mating).

This Spring we checked the various Glenborrodale sites offered by the Estate and chose an excellent position for an apiary, facing south and sheltered on all sides (pictured).

Gill Calver, who lives at and runs Glenborrodale Nursery, also offered us apiary space and we agreed to set up two of the colonies within her grounds, also in a favourable position. This apiary is less than half a mile from the first one.

Developments in 2014

Andrew Abrahams had agreed to visit us to offer queen rearing training over two days in June. Unfortunately, because of poor Spring weather on Colonsay, he was in difficulties with his own queen rearing and asked to cancel his visit to concentrate on getting a fresh batch going. We were disappointed but it was a good reminder than timing is crucial with queen rearing and, to do it successfully, you need to commit to the timetable of tasks and monitoring.

Instead, he agreed that I could join his already fully-booked course on Colonsay early in July and this was immensely interesting, enjoyable and informative. I returned with the first two Amm queens for our project, both overwintered from 2013 in mini-nucs. These queens have now been introducing into nucleus colonies and are laying well. We have grafted larvae from one of them already and have one virgin queen being test-mated near our apiary site. We know there is a long-standing colony of wild bees some three miles from our Glenborrodale apiaries and we hope to learn about the genetics of those bees if the queen mates successfully.

 The remaining four queens due from Andrew were brought over from Colonsay by Steve Sunderland, Lead Bee Inspector on 15 July. These queens were introduced into nuclei and all of them, plus the original two, were taken to our apiary sites the following weekend. We decided to leave the newest colonies to settle and will find out soon if those queens, all bred this year, are laying successfully.

On Sunday 20 July several members attended. We examined the first two nuclei and their queens, enjoyed the sunshine and discussed the use of mini-nucs over our picnic tea (see 3 pics).

Soon the rest of the mini-nucs will be in use again as we seek to breed a daughter queen (or more) from each of the queens received from Colonsay this year.

Looking ahead

SAMMBA, our new association for Sunart, Arnamurchan, Moidart and Morvern, is committed to the Black Bee Project and we have plans to undertake the following over the coming year:
  • Buy further six queens from Colonsay in 2015, all being well. 
  • Over the Autumn/Winter, seek funding for creating a website, buying more equipment and, in two years or so, building a viewing house so we can welcome visitors to see the bees and what we are doing. 
  • Agree our priorities in relation to the breeding queens from those we have. 
  • Agree plans to allow mating of non-Amm virgin queens brought to Glenborrodale, in line with a protocol we will draft. 
We would welcome a visit from representatives of BIBBA and soon I will upload information and photos of our project onto the BIBBA website.
