Sunday 6th rAmble - Killinallan Dunes

Join us this Sunday 6th on our next rAmble along Killinallan Dunes. This will be The Flowers Final Fling as the last flowers of the season bloom. Have an enjoyable Sunday filled with colour and glorious flowers on our gentle nature walk!
Meet at Locked Gate at the end of Loch Gruinart East side, 2pm.
£4 person; Family (2 adults +children) £10; INHT members £2


Wear stout footwear and dress for the weather. Sorry no dogs.

Walking Back In Time

A wonderful afternoon on Sunday's rAmble where David Webster led us on a geological path through time. Down at Kilnaughton Bay, we learnt about the underlying natural processes which have shaped Islay as we see it today, whilst identifying tell-tale rock formations that illustrate the past. 

The walk began with Jura Quartzite, where the rock layers noticeably dip in a South East direction - meaning we were walking in the direction of younger days ahead! Here a rare form of kyanite mineral can be found. This Quartzite is what makes up the Paps of Jura.
Jura Quartzite layered rock
Moving on, as well as examples of compressed sedimentary rock squashed to form slate, we were introduced to a new rock type - conglomerate - seen down by the lighthouse, identifiable by the small pebbles embedded in the layers.

Pebble remains of raised beach

Further along, groupings of isolated pebbles around 20m higher than today's coastline tells the story of the past where sea levels were higher, perhaps due to glacier melt water from the last ice age. These pebbles represent raised beaches bordering the sea cliffs which now sit inland from the shoreline. Similarly, large sea stack rock columns along our path would have once been surrounded by sea.

Fault rock alignment 

The last rock feature lead us down on to the Singing Sands. Here we were able to see an alignment of rock along the sand and out to sea, representing the underlying fault line. The dyke rock feature stands out on the sands and can often be identified by its honeycomb stacking structure and rough sandpaper texture.


 An incoming rain shower towards the end was in fact exactly what we needed to allow the group to get their feet scuffing and hear the Singing Sands "sing" - or squeak to be more accurate! The erosion of the Quartzite rock creates these sands and along with the combination of shell deposits and added moisture, you can enjoy a tuneful stroll on the beach.

Thanks to David Webster for this wonderful walk and helping us get our heads around all the geological terms and timescales! A fascinating walk discovering Islay's ancient landscape. - Lorna

Many Scorpions and not so many Dragons!
















Our pond dipping session this afternoon fell between the showers, in the sunshine.  Nets were plunged into the murky depths of the pool and scooped out a multitude of strange beasties.
 
Lesser Water Boatman came first then the larger paler, red eyed Greater Water Boatman.  Pond Skaters skimmed the surface, midge larvae and the striking Water Scorpions were impressive in their oddness.  We had hoped for some dragonfly larvae but none were found a couple of Damselflies flew above the pond but no big fierce larvae.

On the grasses round about were many hopping froghoppers and leaf hoppers and a sweep of the big grass net revealed the grass was alive with Daddy-long legs, flies and bugs.
Froghopper
The children were extremely enthusiastic and in their excitement left a bit damper than they arrived!


This was the last of the summer activities and we are thankful for teaming up with the I&J Toy Library and funding from Foundation Scotland meant we could provide these activities for free this year, enabling many more families to benefit from the fun gained from discovering and exploring Islay and Jura's nature in the wild.

Investigating the Port Askaig Tillites


45 eager students in search of Tillites

Geology excursion to the Tillite features along the Sound of Islay with the Bolin Centre Climate Students. 
Alasdair Skelton explaining where the Tillites feature in the Islay geology

A beautiful day and some interesting rock formations. 

Could there be too many rocks?!













Granite, Limestone and Quartzite stones and boulders infused in rock the result of glacial till fused in geological time!




There was also a White-tailed Eagle on the walk back and a grey seal watching all the people on the beach. So the identification features provided on last nights 'Islay Wildlife Wonders' talk could be pointed out in the field: Grey Seal - Labrador face; Sea Eagle - big heavy bird just flapping along (no Soaring!)

A pile of treasures discovered on our mini wildlife adventure to Uiskentuie

We scavenged the shore on Thursday for treasures - the beachcombing kind! Lots of shells were found, very big and small, things that were hard, things that were soft, things that were lived in, made a noise, smelled of the sea. 

Beachcombing along the strandline

The fascination with beachcombing is you just never know what the sea might bring you. Although most of our finds were local remains, we found the husk of a coconut (which might have travelled on the currents thousands of miles from the Caribbean!).

Not a hedgehog trying to get in...

...but a coconut husk!

Our lived-in finds were the most interesting - there were egg cases of Common Whelk, a mermaid's purse from a Ray, bivalve molluscs of all sizes and winkles and dog whelks.  There were many forms of seaweed, including the brain-like sea algae Leathesia difformis, and lots of the Eel grass (Zostera) had been washed ashore having been shed.

A grand time was had by all. Join us next Thursday for our last family activity session of the season! Entitled 'Scorpions and Dragons', we'll be doing pond-dipping and mini-beast hunting at a local pond - meet us at Bruichladdich pier at 2pm on the 27th August for onward direction to the pond! See you there!

Next week is Geology Week!

In a major coup for the island, Islay is hosting a conference next week on the unique geology of Islay, run by the Bolin Centre, Stockholm University. In a full programme of events, some will be open to the public, starting with two Climate Change Geological Excursions, and a talk about 'Snowball Earth' in conjunction with the Islay Natural History Trust. Details are as follows:

Tuesday 25th August 2015, 1-4 pm: Excursion from the Lily Loch to the Sound of Islay - Tillite features. Meet at layby near Caol Ila junction.

Wednesday 26th August 2015, 8 am: Excursion from Bunnahabhain to Bolsa/Rhuval, a full day's hard walking. Meet at Bunnahabhain, option of boat transport back from Rhuval (£20).

Wednesday 26th August 2015, 7pm: Illustrated Talk by Prof. Ray Pierrehumbert on the Stones of Islay: Unraveling the mystery of the time when all Earth froze over. Islay Natural History Centre, Port Charlotte. Admission £3 (£1 INHT Members) including refreshments.

In addition, in conjunction with the Museum of Islay Life there will also be a talk as follows:

Thursday 27th August, 7:30pm: Talk by Prof Steven Mithen on Ice Age Hunters and Neolithic Tomb Builders on Islay. The Laddie Shop, Bruichladdich Distillery.

And then on Sunday 30th August, to carry on the geology theme, our afternoon rAmble will be at Singing Sands near Port Ellen, where we'll be answering the question "Why do the Sands Sing?" Meet at 2pm at the cemetery car park, Kilnaughton. The usual small charge applies for this - £2 INHT members, £4 non-members, £10 families.

Should be a great week!


Minor Shoulder-knot

This attractive small moth, with a long name and long feathery antennae, was caught in my garden trap last night. It is the fifth Islay record, with one in the 1970s, two in the 1980s and the last one in 1999. So, there's been quite a long gap since then. It likes damp places with willow as its foodplant and, in this so-called summer, I think my garden qualifies as a damp place and I do some have willows.

A sunny Islay Show! Next, Kilchoman Gala on Sunday!

It was fantastic weather for last week's Islay Show, and what a great show it was. We had lots of people visiting the INHT tent, many of whom had a go on the Bird Race and Fishing games - always popular and lots of fun - and to guess which square the Otter might be in (won by Mr Bull). Many thanks to Bruichladdich for donating the prize - a bottle of Bruichladdich Islay Barley malt whisky! Here's a photo of the tent before it got too busy to take any more photos!

Nearly ready to go at the Islay Show!
To anyone who took photos, we'd love to see them - why not post them to our Facebook page here?

Next it's the Kilchoman Gala this coming Sunday the 23rd between 1 and 4pm at the Port Charlotte Playing Fields, Port Mor campsite. We'll have a stand there again instead of doing the usual Sunday rAmble, so please come and say hello, it'd be great to see you. More prizes up for grabs, more games and sales goods! And don't forget there's the procession of vintage cars leaving from Port Charlotte at 12:30. Should be another great event!

It's an Ard life....

What glorious weather we had for our weekly Sunday afternoon rAmble yesterday - blue skies, warm sun, calm seas....who needs the Med!

View from the Ard
We set off for a stroll round the Ard, which for anyone who hasn't visited yet is an area to the south of the bay at Port Ellen. And what a beautiful spot it is. The views are lovely, and there are wildflowers in abundance.

A Seashore Safari Week

Two visits to the seashore to try and make the most of good tides this week. 

A visit to the Battery shore west of Bowmore on Tuesday, a sunny but very blustery day.  The water didn't go out as far as it should have due to the winds pushing water up the loch, however, sandy shores and mussel beds were open and exposed. Various shrimps and fishes were caught and small shore crabs.  The highlight was a Sea Stickleback.























Jura on Thursday was contrastly a warm, calm, intensely sunny affair, many edible periwinkles were collected by one eager young lad filling his net, crabs (common shore and an edible), shrimps and sea anemones were collected and put in the bucket for closer inspection. 









Inspecting the finer features of the edible periwinkle












'Flappy' was missing one of its claws and a leg or two!
 















The star of the afternoon was a Squat Lobster (Munida rugosa), duly named 'Flappy', found in a small pool higher up on the shore than I would have expected!  I am of the opinion that this individual had bid an escape for freedom, possibly from the Hotel and some ones dinner menu!  It was returned to the sea at the end after many photo opportunities.

We have a break from exploration activities until Thursday 20th (when we will be beachcombing on Uiskentuie Strand) due to the Islay Show this Thursday.  We have a stall there so do come and see us, hope for fine weather!
