A brightly sunny day, too good to miss, so I headed for the Little Orme which offers reliable sightings of a wide variety of wildlife in a relatively compact area with little effort required. Well-used by local people and visitors to the area and part of the route of both the Wales Coast Path and the North Wales Path, the pathways of the lower part of the reserve particularly are often very busy. Opportunities for uninterrupted attempts to photograph the more wary small woodland birds may be limited, but despite close human proximity the birds carry on regardless and largely unnoticed.

I use the entrance to the reserve sited at the back end of a residential area. Today the lawns of the unfenced front gardens were providing foraging for jackdaws and a few Pied wagtails. Outside the breeding season wagtails gather here in the evenings before setting off to roost comunally for the night. On the roofs were perched gulls, Wood pigeons and Magpies and a singing Greenfinch. There’s a thriving House sparrow population here too and cheerful chirruping greeted me as I climbed the steps up to the reserve, where they frequent the tangle of brambles and shrubs there.

The Fulmars have returned to their nest sites high on the cliffs. Although a small colony of just 10 or so pairs they draw attention to themselves by noisily proclaiming their territories and can be heard as soon as you enter the site. I looked out for Ravens that have used the same nest site up on the cliff for many years, but I didn’t see or hear them today.

I was pleased to see a pair of Stonechat though, one of my favourite little birds. They were in the same area within which a pair successfully raised a family last year, so I like to think this may be the same pair. I couldn’t get close enough to them to get good photographs, but I prefer to use ‘real time’ images whenever possible, so these were today’s best record shots.

The biggest draw to the reserve are the Grey Seals that at this time of year can be fairly reliably seen, when the tide is out, hauled up on the stony beach of Angel Bay. Today there were about 20 females and their rapidly growing pups, a few in the water, the rest sleeping blending perfectly into the background of stones and rocks.

Jackdaws are without doubt the most numerous birds here and a great number gather here to breed, nesting on the rocky cliff faces. They spread throughout the site to feed and also separate into small flocks that venture back and forth to forage in a wide variety of places locally, arriving back noisily to land on the cliffs where they site their nests. It is good to see them foraging and nesting in their natural cliff habitat rather than in villages roosting on roofs and nesting in chimneypots.

Blackbirds are another numerous bird here as are Robins and Dunnocks, with males singing from shrubs throughout the site. Close to the backs of houses trees and shrubs are frequented by good numbers of birds. The House sparrows are nesting close to a busy path here and a chorus of chirrupings emanated loudly from within the shrubs, but despite being audible from some distance away, they stayed well hidden. Also seen and heard singing here were Chaffinch, Greenfinch, Wren, Great Tit and Blue Tit.

Wildflowers appear a little later on this windswept clifftop than in more sheltered areas, but there’s plenty of the early flowering Alexanders on show.

On a sunny day last week I intended to spend some time checking out the birdlife on Rhos Point to see what treats the autumn migration had already brought to us. I started out on the roadside where there’s a posh new sign on the roadside above the bijou St Trillo’s Chapel, the favoured starting point for many of my seashore posts.

St Trillo’s Chapel, Rhos on Sea

It was windy here and decidedly chilly as it can be when the tide is coming in. A quick look and listen from the promenade revealed a good number of cormorants, gulls, oystercatchers, redshanks and curlews, but all still too far out on the tideline on the mussel bed to see easily.

I picked up a few seashells of some of the most commonly occurring species here.

Despite the sunshine, this was definitely not a day to hang around on the shore, so I turned to walk along to Penrhyn Bay, hoping I might find a Rock Pipit or two amongst the huge rocks of the seabreak.

Fox -and-cubs flowers on the grassy embankment bending in the wind

This view of the Little Orme clearly shows the tiers formed by quarrying.

I soon knew I wasn’t going to enjoy battling along against the cold headwind, so at the earliest opportunity dropped down onto the parapet of the seawall where a passageway is formed between the wall and the seabreak rocks. It was still windy here but not quite as strongly, besides which this passageway fascinates me as a habitat for an ever-increasing collection of plants and at this time of year it can be a good place to spot rock pipits and pied wagtails. And the rocks themselves are endlessly fascinating.

The turquoise green of the vein in the rock above puts me in mind of the verdigris you get on copper. The one below has sparkly white and pink crystal-like parts held within it.

I spotted a bird on the rocks close to these steps and went down to see if I could find it again.

Steps going down to the seashore

I managed a quick shot before it disappeared. Definitely a pipit.

In the winter and in rough windy weather the sea reaches the top of these steps; the bottom few are bleached almost white, their edges smoothed, curved and shaped to form channels by seawater covering them and cascading back down.

Continuing along there’s a stretch that is particularly flowery. There’s a lot of red valerian interspersed with an array of wild plants and garden escapées.

Between the breakwater and the rocky shore there is a patch of flowery grass

and behind the rocks scrubby shore plants grow amongst the sand and stone chippings. This is the best place I know for fairly reliable sightings of linnets that come to forage for seeds. There were linnets there when I arrived, which I realised when they all took off and headed off across the road towards the golf course. From past experience I thought if I sat and waited on the steps beneath the sea wall they may well come back. Sitting quietly I realised there were still birds close by that gradually came back into the open in front of me which turned out to be a Northern wheatear and a pipit. I want to say it was a Rock pipit as this is a likely spot to find them, but it had an olive-green tinge to its plumage and may have been a Meadow pipit.

Lovely wheatear though.

As hoped the linnets came back too, a small flock of 10 or 12 birds, albeit too far away to photograph well.

August so far has brought mixed weather, days have been mostly warm, but many have been cloudy or overcast and occasionally there’s been some sunshine.

Looking across to Conwy Estuary from Bryn Euryn

It’s only been a week or two since my last visit to Bryn Euryn, but now rapidly approaching late summer, much has already changed. Many plants are setting seed, there are ripe wild raspberries, a few ripe blackberries and sloes, still as hard as bullets.

Purple sloes are swelling on Blackthorn

Last year there were sparse crops of acorns and sloes, this year may be more bountiful.

On a last hogweed flowerhead, a new-to-me, furry little hoverfly; it is one of a number of species referred to as a bee mimic, but it doesn’t really look like one.

Another hoverfly caught my eye, it was basking on a bramble leaf and as the sun caught it, the insect shone a bright metallic golden bronze colour.

Hoverfly-ferdinandea cuprea

About to enter the meadow, I caught sight of a Speckled wood butterfly basking on an Oak leaf. I moved in to take a photograph as I haven’t had many good opportunities with this species so far this year, then caught sight of another butterfly sitting on a leaf slightly higher up.

7/8/15 – Purple Hairstreak

I moved in a little closer and realised this was a butterfly I had never seen before other than in pictures, a Purple Hairstreak. A species that spends most of its time in and around the tops of Oak trees, I was surprised and delighted to see it and tried not to alarm it as I focussed the camera. It moved a little to reveal two small orange eyespots on its hindwing, but just as I had it back in focus the Speckled wood flew up and chased it away. I waited a while to see if it would return, but no luck. At least I know to look out for them here again!

The colours of the landscape are changing subtly. Hay has been cut and in many places baled and put safely under cover. Meadows of seeding long grass left standing have taken on a golden hue and on our limestone hill, the wildflowers typical of late summer are at the peak of their flowering. Most are ‘tough’ plants, Knapweed, Hemp agrimony & Ragwort, which are all imortant nectar sources for insects.

It’s been a while since I had a good opportunity to photograph a Green-veined White, so I was pleased to see this fresh one on a Knapweed flowerhead.

Rhos Point from the Little Orme

Rhos-on-Sea is a popular seaside venue that is busy with people visiting most of the year round, particularly at weekends and when the sun shines, but they don’t come here for its beach. The seashore, wrapped around the flat fortified headland of Rhos Point, is not the most beautiful in North Wales: a general first impression may well be of an expanse of flat shoreline littered with variously sized brown-coloured rocks and boulders. No easy strolling or picnicking here.

However, between the rocky shore and the sea lies an expanse of long-established Mussel beds which is highly attractive to visitors – of the avian variety. Large numbers of a variety of species of sea and shore birds will be returning here this month from their summer breeding grounds to spend the autumn and winter to feast on the gourmet seafood on offer here.

There may be a few early arrivals, maybe a Turnstone or two, but for now, approaching mid-August, the resident breeding birds, the Herring gulls, a smallish number of Lesser Black-backed gulls, Cormorants, plus a few Oystercatchers have the place more or less to themselves.

Great Black-backed gulls, adults & juveniles, Herring gull & Oystercatchers

Soon they will be joined by large numbers of Curlews, Redshanks, more Oystercatchers, Turnstones, Dunlins, Ringed Plovers and Sandwich Terns. If we are lucky there may be a few Purple Sandpipers in the mix, and there will doubtless be a few temporary visitors stopping to feed before escaping to warmer climes. There will be Rock Pipits and Pied Wagtails amongst the huge rocks of the sea defences. So much to look forward to!

Without the movement and cries of the absent birds the landscape appears harsh, a sombrely coloured, barren place devoid of life. But look more closely and you’ll see it is in fact a living landscape, richly populated by hosts of small sea creatures, which is of course why the birds head here for the winter.

On close inspection, the rocks that appear a uniform brown colour from a distance are actually encrusted with colonies of barnacles, millions of them.

Me it delights in mellow autumn tide, To mark the pleasaunce that my eye surrounds, The forest trees like coloured posies pied, The uplands mealy grey and russet grounds; Seeking for joy where joyaunce most abounds……. from Autumn by John Clare

Autumn certainly has been joyous this year and even the blustery tail-end effects of hurricane Gonzalo have failed to provoke most of our habitual complaints about the weather. Temperature-wise, a walk I took on Bryn Euryn just a couple of weeks ago felt more like early summer than approaching winter and although many of the signs of autumn were in place, there were a surprising number of wildflowers in bloom and butterflies, bees and various flies on the wing.

The woodland tracks are covered with layers of dried fallen leaves that rustle when stepped upon and the soft musky scent of their decaying matter fills the air.

Wild clematis is prolific throughout the reserve and curtains of the fluffy dried seed-heads is draped over vegetation of varying heights and is living up to its common name of Old Man’s Beard.

Although there are bountiful berry crops, the oak trees do not seem to have produced many acorns this season.

There are ‘crops’ of spangle galls though.

Before climbing up the steep track through the woods on the way to the summit I sat for a few minutes on a rock to note down what I’d seen so far and was scrutinised for a few seconds by a buzzard that flew in over the treetops. This is a favoured spot of the locally resident buzzard, known to local visitors to the site as Lucifer and if you are here for any length of time you have to be quite unlucky not to get at least a glimpse of him here. He was accompanied by his mate today and didn’t linger, moving away in a leisurely circling kind of way towards Penrhyn Hill and the Little Orme.

Buzzards circling Penrhyn Hill

I noted: ” I’m sitting on one of my favourite rocks. It’s around noon, the sun is high in a blue sky with just the faintest wash of wispy white cloud and is so hot I can feel it burning my legs through my jeans. The grassy areas have all been cut but a few wildflowers in bloom including rockrose, harebell & a bit of hogweed. There are butterflies, mostly speckled woods, but also a red admiral. Drone flies come to bask on the sun-warmed rocks and several wasps are seeking available food sources. Birds are still fairly quiet, I’ve heard the occasional song of a Robin and Blue and Great Tits calling to one another as they flit around foraging for food, but apart from the ever-present Crows everything else is keeping a low profile.”

Moving onwards and upwards along the track that leads out onto the ‘downland’ side of the hill I could hear drying leaves crackling in the heat of the sun. On the woodland edge there were several speckled woods flitting about, pausing often to settle on oak leaves. All appeared to be dark in colour and were not fully basking, but holding their wings partially closed.

I photographed another insect here too: it looked like a small bee but was behaving more like a hoverfly.

There is a beautiful silver birch tree on the woodland edge. Its leaves are beginning to turn colour and it has attractive fruiting catkins that look like a bit like a small slender fir cone from which, during the winter and aided by birds, tiny winged nutlets will be released.

The grass has been cut on the hillside too and the ground is criss-crossed with a lattice of bramble stems. There are a few plants of the wild Goldenrod still in flower, while others have gone to seed.

There was a fair amount of scabious still in flower and was attracting a busy little Carder Bee.

There were a few eyebright plants still with their usual white flowers, and one that I came upon had pretty pink-purple edged petals with a yellow patch in the centre.

The views from the hillside were outstanding today as it was perfectly clear and bright which rarely happens in the summer months.

Burnet Rose- Rosa pimpinellifolia

burnet rose, low-growing white rose, Phragmidium rosa-pimpinellifoliae, rosa pimpinellifolia

Family: Rosaceae Other English name: Pimpinell Rose Welsh name: Rhosyn Dewi (Rhosyn y Twyni) Irish name: Briúlán

There is a glorious stretch of these lovely and very prickly roses on Bryn Euryn that are fully in flower now.

Beautiful Burnet Roses

The Burnet Rose is a low-growing species, largely confined to dry sandy places near the sea; it is particularly abundant on dune systems in South Wales. Inland it may be found in calcareous areas, generally chalk downland or limestone pavement.

Its natural distribution is limited to Europe and Asia except for part of the Atlas Mountain Range in North Africa.

A prickly stem full of blooms

It is a rather low erect deciduous plant usually growing to 20–140 cm high but it can sometimes reach up to 2 metres.

The plant spreads by suckers and can cover large areas. The stems are protected by numerous stiff bristles and many sharp straight prickles. The young stems and prickles and the mature leaves tend to be very red with young growth a bright scarlet and older growth a deep maroon.

‘Some people are always grumbling because roses have thorns. I am thankful that thorns have roses’.

Alphonse Karr (1808-1890)

Burnet Rose

The flowers are cream-white although rarely also pale pink and are 2–4 cm in diameter with five petals. prominent golden stamens and they have the sweetest, most delicious scent of any of native roses.

Visited by bumblebees

Bumblebees seem to love them, perhaps because they do have a hint of honey in their scent.

This small bumblebee was enjoying a really good rummage around

Soon the petals fall off the roses but the stamens look pretty too. The leaves are small and oval, very like those of the salad burnet (hence the name).

Without petals

And later in the year there will be a crop of distinctive globular dark purple to black hips.

Rust fungus on Burnet Rose stem

A brilliant-orange rust fungus Phragmidium rosa-pimpinellifoliae is also common on the plants.

The plant’s names

R. spinosissima (pimpinellifolia) has been known by many different local names and it has attracted its own folklore. In some places, people have given it a vernacular name based on the resemblance of the leaves to a Burnet (Sanguisorba ) and therefore, for example, called it the Burnet or Pimpinell Rose in English or Rose Pimprenelle in French. In other places, it was the prickly stems that caused it to be known as Bodicasti Sipek in Slovenia, for example, or Piikkiruusu in Finland.

Burnet Rose growing alongside the related Salad Burnet on Bryn Euryn

In Iceland, it has the name pyrinros which literally means ‘Thorny Rose’ but the same Icelandic word means ‘Sleeping Beauty’ and may refer to its early flowering – the beautiful rose waking up after the long dark Icelandic winter! In Norway, this rose is called ‘Trollnype’ – associating it with the trolls of Norwegian folklore. Elsewhere, it is named after the coastal sand-dunes where it grows so, for example, it is Klitrose in Denmark,Duinroos in The Netherlands or Dünen Rose in Germany.

Medicinal uses

The plant was initially grown in gardens for its herbal properties and it was one of the first roses described and illustrated in 16th century herbals of Northern Europe. Its hips and leaves have been used to make a tea and, in some places (particularly Denmark) a liqueur is still made from its hips. In recent years, it has been the subject of intense research to investigate its special pharmaceutical properties. The chemical constituents have recently been summarised by Mayland-Quellhorst et al (2012). Its dark purple or black ‘fruits’ (heps) are high in vitamins and antioxidants.

How to build a beach

14 Sunday Apr 2013

The beautiful but rugged coastline of North Wales is subject to some serious battering by winds and waves throughout the year and although we love to live and holiday here, of course we prefer it to be on our terms and so demand protection from the elements too. We also need to make a living and as this whole area is designated as an outstanding area of natural beauty, capitalising on those natural assets by way of tourism is the way things are set to go forward. Great lengths of piled up rocks are already in place reinforcing the defences of the sea wall from Rhos on Sea to Penrhyn Bay, but now work has begun to improve the defences of Colwyn Bay.

A section of the Colwyn Bay promenade being battered by the sea, March 2013

Colwyn Bay was one of the North Wales holiday resorts popularised by the Victorians. It was accessible to them by way of the railway line between the ferry port of Holyhead on the Isle of Anglesey, and London, that was built to facilitate the transport of mail between the two places and onwards to Ireland by sea. It remained popular as a holiday destination for several decades following, my own parents spent their honeymoon here in 1946, but began to go into decline during the late ’80s, in common with many other British seaside resorts.

In 2010 a ‘masterplan’ was revealed to regenerate the area which includes plans for a new sandy beach to be constructed to improve sea defences and to allow people access to the shore throughout all tidal states: currently you can only walk on the shore at low tides.

As reported at the time by The Weekly Post, this build-a-beach project is not going to come cheap.

“Conwy County Council’s cabinet voted to pledge £667,000 to secure a grant of £2m from the Welsh Government to improve the town’s sea defences. The authority had already secured an additional £1m of funding from the Welsh Government for the Colwyn Bay Waterfront coastal defence scheme by offering up £333,000 of supported borrowing from this year’s capital programme. By agreeing to pay the £667,000 from next year’s (2013) budget the council…will see beach sand material imported onto Colwyn Bay seashore which is now mostly pebbled. This will result in 50m of sand to help protect the promenade.”

Work began on building the new beach on 21st March and the major project of engineering is proving to be quite fascinating. To begin with two lengths of steel pipeline were constructed on an unobstructed stretch of Pensarn beach, one a kilometre long, the other about 400m long. The two sections were then floated out at high tide, lined up and welded together. The pipeline was then connected to the steel dry-line which is pumping the sand onto the beach. A rubber floater line was also connected to the sea end of the steel pipeline, and this section of pipe will connect to the dredging vessel.

Sand begins to pour from the pipeline against the existing sea wall. Picture from Daily Post.

The dredging ship, the Barent Zanen, sailed here from Rotterdam and prepared to dredge sand from the seabed of a site 20 nautical miles north of Colwyn Bay, located within Liverpool Bay. The ship is taking the sand from the sea bed approximately 20 miles north of Colwyn Bay, and then sailing in and anchoring about a kilometre offshore. Around 10,000 tons of material is brought in each trip and it is estimated that the beach will be topped up at a rate of 25-30,000 tons a day.

The Barent Zanen off Rhos Point, connected to a smaller tug that connects the two ends of piping together

The sand and sea-water mix is blasted onto the beach during periods of low tide and attracts a huge amount of interest from a large number of gulls that arrive to take advantage of seafood, freshly delivered from the seabed. As far as I am aware, no mention has been made of any potential damage the dredging may be doing to the flora and fauna of the seabed in the dredging site, but I can’t help wondering.

The dredged sand and seawater mix arriving on the shore brings about a frenzy of gull activity

Following each delivery of sand, which is deposited in one large pile, it is distributed by mechanical diggers and bulldozers. The work often attracts groups of interested onlookers, and no doubt at least some of the big boys watching would love to be having a go.

6th April, the new beach so far

The operation will take place 24 hours a day, seven days a week and should last for a period of up to four weeks, depending on the weather, which thus far has been pretty wild. Many local people are wondering how long the beach sand will stay put and how much it’s going to cost them…..?

Late summer wildflowers and insects of the Little Orme

The weather took its toll on the cliff-top flora and fauna of the Little Orme too, although I think perhaps it’s not so much that the insects were not there, more that they were less able to be mobile, so were not as visible as they are in warmer, drier conditions. I took the following pictures on a warmish, sunny but fairly windy day just past the middle of August when everywhere was still damp from rain.

Ragwort is blooming strongly and every plant is supporting a colony of cinnabar moth caterpillars.

The Cinnabar moth larvae are growing fat on ragwort

The flowers of the ragwort are much in demand too, particularly by hungry hoverflies.

Mating pair of soldier beetles

I was still on the lookout for soldier beetles and did eventually manage to find one pair; there were dozens of them this time last year. I didn’t even manage a very good photograph as the wind was blowing the ragwort stem they were on.

I walked towards the cliff edge above Angel Bay, drawn by a large patch of sunny yellow birds-foot trefoil mixed in amongst long grasses.

As I had hoped, this flowery area turned out to be quite productive in terms of insects. I first spotted a Common Blue butterfly very low down on a grass stem, then followed a Small Skipper until it too came to rest on a flower.

Small Skipper –

That was followed by a first sighting of a Burnet Moth fluttering across the grass and flowers, and once I had ‘got my eye in’, I soon realised there were a good few more.

6-spot Burnet moth –

The Burnet moths were mostly attracted to the thistle flowers growing at the side of the pathway; at one point I found four of them all on the same plant.

Stopping to photograph the single moth I was distracted by the chirping ‘song’ of a grasshopper, which I found on a grass stem just behind me. I am not great at identifying grasshoppers, but I think this was most likely a Meadow Grasshopper – Chorthippus brunneus.

Walking along a narrow track through the long grass I saw an insect I did not immediately recognise on a thistle flower. It took little notice of me taking photographs of it, just carried on working its way around the flowerhead. To identify it I searched my favourite website for insect identification http://www.naturespot.org.uk, which is a Leicestershire site but usually comes up trumps for me. From that I believe my mystery insect may be of the Sawfly species, Tenthredo notha – but as always I am more than happy to be corrected.

Sawfly- Tenthredo notha

At the bottom of the steep grassy track that takes you higher up on the cliff, a decent number of butterflies were dancing around the bramble flowers. There is red valerian growing there too which is also a favourite nectar plant of butterflies and more ragwort attracting hoverflies. Butterflies included Large, Small and Green-veined Whites, Meadow Browns, Gatekeepers and a Tortoishell.

I stopped half-way up the incline to draw breath and to take a photograph of the view.

At the top there is a flat grassy area, popular with Jackdaws that nest on the cliffs and grazed by sheep, where the remains of some sort of winding mechanism still stands as a memorial to the quarrying that is responsible for the shape of the Little Orme.

Back down at the bottom and a quick scout around before heading home produced more flowering plants:

Eyebright – Euphrasia nemorosa

Toadflax- Linaria vulgaris

Vervain-Veronica officinalis

Lesser Burdock-Arctium minus

Another grasshopper, which I think is a Mottled one as it has curved antennae, but if not then its a Field one.

A mottled, or maybe a field grasshopper

Then finally, as testament to all the recent rainfall, a big fat slug…

Although this slug is black, it is a Large Red Slug-Arion ater, which has a range of colour forms.

You probably do not need me to tell you that the weather this month has, so far, been rather un-summery, particularly in this part of the country, so I won’t bore you with unnecessary details. However it has impacted on the opportunities I have had to get out and about and record the effects it has had on the local wildlife, if any. That’s not to say I haven’t been keeping my eyes open and looking for opportunities to record what I am seeing, but rainy and windy days are not very conducive to taking photographs of insects or indeed flowers that are being buffeted by the weather.

The first day of August brought a mixed bag of weather conditions, but I tried to make the most of a sunny spell towards the end of the afternoon by visiting the Little Orme. It was windy up there, but there were a few butterflies out feeding in odd places sheltered from the wind. In the majority were Meadow Browns, staying well down in the long grass, but there were a few Gatekeepers enjoying the abundance of bramble flowers, but not settling for long enough to photograph, one of two whites and one gorgeous Tortoiseshell. There were hardly any bees or hoverflies or indeed any insects flying.

Ragwort is flowering now; this somewhat contentious plant is an invaluable source of nectar for a myriad of insects and the host plant of the unmistakeable black and yellow striped larvae of the Cinnabar Moth, many plants are already supporting numbers of them.

There are some interesting plants flowering here at the moment; one is the pink-flowered Centaury and the other is Yellow-wort-Blackstonia, neither of which were showing open flowers today.

Common Centaury – Centaurium erythraea. Welsh, Bustl yr daear

Centaury flowers tightly closed

A member of the family Gentianaceae, common centaury thrives in dry grassy places and is especially common on stable sand dunes and on dune slacks.

A small plant of the gentian family, with flat-clusters of star-shaped rose pink flowers, which open only when the sun shines. The stem is four-cornered and grows to a height of 4-20 inches (10-50 cm).

Etymology & traditional medicinal uses

Centaury takes its name from the Greek centaur, Chiron, who was half man, half horse. Chiron was a teacher of the gods and skilled in the uses of medicinal herbs, and legend has it that when he was shot accidentally by Hercules with a poison arrow, he healed himself using common centaury.

This is a truly versatile herb that apparently may be used for nearly any problem. It is a bitter-tasting herb, which Culpeper noted “Tis very wholesome; but not very toothsome.” It is used for a variety of digestive problems, including colic, bloating, heartburn, dyspepsia, to stimulate appetite, ease constipation, and to aid the proper assimilation and digestion of food. An extract prepared with vodka (!) is given for high blood pressure, liver and gall bladder problems. Lotions containing centaury have been used on the skin to remove different kinds of blemishes. It is used as a treatment for muscular rheumatism, gout, convulsions, tuberculosis, cramps and snakebites.

Externally, the juice applied to the eyes will clear the vision, and applied to wounds, ulcers, old sores, bruises, will help promote healing. It kills worms as do most bitters and a decoction externally applied will destroy lice and other parasites in the hair.

Bach Flower remedy

I am familiar with Centaury through my work as an Holistic therapist, having studied and extensively used the Bach Flower remedies. It was one of Dr Edward Bach’s original ’12 Healers’.

The Centaury remedy is for people who find it difficult to say ‘no’ to others, usually kind, gentle souls who like to help that may find themselves being taken advantage of and becoming resentful. The willing servant ending up the slave of another’s wishes. The remedy doesn’t harden or make us callous,rather it supports the development of courage and self-determination. We are better able to draw a line and make space where we can be ourselves, free of the desires and commands of others.

Yellow-wort – Blackstonia perfoliata. Welsh, Canri felen

Yellow-wort keeps its flowers tightly closed when the sun is not shining

A distinctive plant with grey-green leaves arranged in pairs to form ‘cups’ up the stem and bright yellow flowers that only open in the brightest sunshine. Yellow-wort is lime-loving and in Wales occurs in the greatest numbers dunes along the northern and southern coastal strips, particularly on marshy dune slacks. It generally flowers from June to October in Britain where it is widespread but not common.

In common with the afore-mentioned Centaury, Yellow-wort is a member of the family Gentianaceae, but is distinguished from all other family members, which have flowers with either four or five petals, by having six or even eight flower petals. It is tricky to catch the flowers open as even on the brightest, sunniest days they close very quickly if as much as a cloud passes over them.

Etymology & use

Yellow is self-explanatory as the colour of the flowers of the plant and wort was commonly used in the names of plants and herbs, especially those used formerly as food or medicinally. In this particular case I have been unable to discover any history of the plant being used medicinally, but a yellow dye can be obtained from the plant extract, so that may cover it.

The Latin Blackstonia refers to the 18th Century botanist and apothecary John Blackstone. Perfoliata.. through-leaved .. referring to the leaves which are fused together at the base with the stem threading its way through.

John Blackstone (1712–1753). Blackstone worked in London and spent his holidays at Harefield, north Middlesex. His major work was Fasciculus Plantarum circa Harefield sponte nascentium. Cum Appendice, ad Loci Historiam spectante which catalogued plants he found in Harefield and included the precise location of the rarer plants. He was working on a second work when he died prematurely aged 41.

Robin’s Pincushion

Robin’s Pincushion

The Rose bedeguar gall, Robin’s pincushion gall, or Moss gall develops as ” a chemically induced distortion of an unopened leaf axillary or terminal buds” occurring most commonly on Field Rose (Rosa arvensis) or Dog rose (Rosa canina) shrubs. This fascinating distortion is caused by the parthenogenetic hymenopteran gall wasp (Diplolepis rosae (Linnaeus, 1758))

To find a wasp you would have to look around the new green leaf buds in late May as it prepares to lay its eggs. Then the female diplolepis lay up to sixty eggs within each leaf bud using her ovipositor. The asexual wasps emerge in the spring; less than one percent are males.

The bedeguar gall is surrounded by a dense mass of sticky branched filaments, giving the appearance of a ball of moss. Its filaments start off green, gradually becoming pink that turns crimson and ages to a reddish brown. They are at their most attractive from about now to September, as from then they begin to lose their hairs, although they remain in place until the new gall wasps emerge in the spring. A large specimen can achieve up to 10 cm in width.

Etymology

The term ‘Bedeguar, Bedegar or Bedequar’ comes from a French word, bédegar, but that originated from the Persian, bād-āwar, meaning ‘wind-brought.’

The Robin in ‘Robin’s pincushion’ refers to the woodland sprite of English folklore, Robin Goodfellow, otherwise known as Will o’ the wisp and Puck.

Folklore & traditional medicinal uses

Folklore tells us that if a Robin’s Pincushion is placed under one’s pillow it aids sleep and the gall was therefore known as the ‘Sleep Apple’.

The galls have apparently been used in the treatment of whooping cough and carried as an amulet to ward off toothache.

Dale beach and the Gann Estuary

We returned home via the village of Dale which is situated on the south eastern tip of the Pembrokeshire Heritage coast and is also on the route of the Coastal Path. Its beach is located on the Milford Haven estuary between St Ann’s Head and St Ishmael’s in Pembrokeshire, South Wales. There is a lot of history attached to the village and surrounding area, but we had come to have a quick look at the unique habitat that lies at the back of its shingle beach.

The view across Dale beach; the refinery at Haverfordwest is just out of sight behind the headland on the left of the photograph

The beach is mainly shingle with some sand at low tide.

The shingle beach is a colourful mixture of red sandstone and grey/green silurian stone

The gritty sand is pink and stones on the beach occur in an infinite variety of shades of pink/red, grey and green

The red soils of the area are derived from old red sandstones seen at Lindsway Bay and Sandy Haven that are some 395 million years old. There are also occasional exposures of even older rocks, aged at 420 million years. The cliff tops are covered with glacial till made of unconsolidated material dumped by melting ice around 20,000 years ago and fields that have been ploughed are visible for miles as the soil is a bright red in colour.

At the back of the shingle beach is a sand ridge and behind that an area of low lying land and the brackish artificial Pickleridge Lagoon, formed by the flooding of gravel pits that operated between the 1950s and 1980s. This has now become established as a saline lagoon and together with the extensive salt marsh in the Gann river valley, the area has become a haven for wildlife, particularly for wading birds and plants.

There were very few birds around today, a few Oystercatchers were out on the tide line and a number of Mute Swans on the edges of the lagoons, but other than that we saw only crows, a pair of raven flying overhead and a magpie or two.

There are some interesting plants growing here though, including the largest expanse of yellow flowered Kidney Vetch I have ever seen.

Grasses

The largest expanse of kidney vetch I have seen

Kidney Vetch – Anthyllis vulneraria

Kidney Vetch-Anthyllis vulneraria

The small yellow flowers of Kidney Vetch are held in a cluster atop little woolly cushions, at first glance resembling a clover. The plant flowers from June to September and is a distinctive feature of sand dunes, chalk grassland and cliffs across the UK where it may spread to cover bare ground if it finds the right conditions.

The flowers are mainly yellow, but can also be found in orange and red forms. Each flower has its own hairy calyx (containing the sepals), giving the flower cluster its woolly appearance. The leaves of Kidney Vetch are divided into narrow leaflets that are silky and white underneath.

Kidney Vetch & the Small Blue Butterfly

Kidney Vetch is the sole foodplant for the larvae of the Small Blue Butterfly – a seriously declining insect which is classified as a Priority Species in the UK Biodiversity Action Plan. Although Kidney Vetch itself is not threatened, the habitats in which it grows are becoming fragmented and being lost at a rapid rate; for example, it’s estimated that we’ve lost 80% of our chalk grassland over the last 60 years.

Traditional medicine

Kidney Vetch has long been used in herbal medicine as an astringent; the name ‘vulneraria‘ means wound-healer and applying it to wounds reduces bleeding. As the common name implies it is also used in the treatment of kidney disorders.
