Plastic waste and Portuguese Men O’War on a Devon beach

Last week, on a very windy day well before storm Ophelia arrived, we visited Leas Foot Sands, one of the small coves clustered around Thurlestone Bay in South Devon.  Thurlestone Rock, a stone arch or “thirled stone” is a prominent local landmark located in the Bay.  As well as being a popular attraction for canoeists and wild swimmers, the Rock gives the village of Thurlestone its name.

When we reached Leas Foot Sands, we stood and gazed across the water at the elemental scene.  A gusty, gale force wind blew from the sea, a powerful natural force affecting everything in its path. It had been hard enough to walk there, buffeted as we were from side to side and, now, above the beach and just about able to stand, we felt specks of sand flick across our faces.  The sea was a uniform grey under the overcast sky, but the wind created many white horses offshore and a sense of agitated movement.  Chunky waves continually attacked the curving apron of yellowish-brown sand, each one finishing in a foaming mass of white water that mingled with the wind giving the air a moist, salty essence.

At the southern side of the beach, the sand and rocks were coated with a slightly unsavoury looking, brownish foam.  I remember being alarmed, some years ago, when I first saw this spume on a beach in Cornwall and feared effects of detergents. I now know that it is a mostly natural phenomenon, caused by a high wind interacting with organic matter from marine phytoplankton.

A few hardy plants grew at the back of the beach beyond the strandline, bringing welcome colour on this mostly monochrome day.  Brash yellow and white daisy-like flowers of sea mayweed bobbed in the wind and pale lilac blooms of sea rocket kept safely close to the sand along with their fleshy green leaves.  A few pink lollipop flowers of thrift struggled on exposed cliff edges.

Further down the beach, bands of dark seaweed stretched in broad arcs parallel to the shore.   The thickest band of seaweed was the result of the morning’s high tide; here the seaweed sparkled, seawater dripping off dark fronds as the tide receded.  Mixed with the seaweed were various colourful examples of plastic waste, mostly bits and pieces of fishing tackle or rope, but I also saw an old plastic yoghurt container, a bright green plastic straw and several smaller shards of plastic.  A bright pink balloon-like object clung to a flat stone nestling among the damp seaweed.  I wondered if this was some kind of joke as it vaguely resembled an inflated condom but I abandoned that idea when, further along, I came across several similar objects.  Hazel put me right, telling me that these were Portuguese Men O’War, very colourful but dangerously stinging organisms that float on the sea surface trailing long tentacles, until driven in by high winds.  There have been reports of swarms of these colourful creatures on several beaches along the south coast and warnings that the number will increase with storm Ophelia.

Behind the wet strandline was a sparser band of dry, black seaweed, presumably resulting from sporadic higher tides.  I started looking around this sector digging up the sand with a garden trowel to see what I could find.  This was too much for a woman who had recently arrived on the beach with her child and friend.

“What are you looking for?” she asked me.

“I’m trying to find plastic nurdles, have you heard of them? “ I replied

“Do you mean those small bits of industrial plastic?”

“That’s right, but I can’t find any here” I continued.

“I suppose that’s good” she suggested.

I carried on looking but was unsuccessful.  Hazel, however, found six of the lentil-sized plastic pellets, a mixture of grey and blue, on the other side of the beach.  Earlier in the year, someone had reported collecting hundreds of plastic nurdles from this beach; perhaps we were unlucky or perhaps conditions had changed.

Marine plastic pollution is one of the major environmental challenges of our time and something I want to return to in future posts.

Thomas Hardy’s Egdon Heath

Mistaken marriages, passionate affairs, tragic deaths, richly interwoven with folklore and superstition.  This is the complex concoction contained in The Return of the Native, one of Thomas Hardy’s great novels.  Hardy set his narrative on the semi-fictional Egdon Heath, a “vast tract of unenclosed wild” that assumes a claustrophobic, controlling influence on his characters.  Hardy’s Egdon Heath has many of the features of the heath landscape that once filled the space between Dorchester and Bournemouth.  I wanted to experience Egdon so, on a warm, humid day towards the end of July, I went to Winfrith Heath one of the surviving fragments of this Dorset heathland.

Winfrith Heath 1
Looking across the heath showing the subtle colour effect of the heather flowers

 

I followed a sandy soil track on to the heath, descending gradually between borders of gorse and low trees.  As I gained distance from the road, long views opened up across the gently undulating terrain surrounding me and an eerie quiet descended, broken only by trains passing on the heath-edge line.  Apart from the occasional stunted tree and a few drifts of pale green bracken much of this part of the heath appeared featureless and barren.

Closer inspection, however, revealed some of the heath’s special wildlife.   Near the path edge, the cheerful purples, pinks and violets of the three common species of heather showed well.   These heathers flourish across the heath alongside rough grasses and gorse, and their bright pastel-coloured flowers lend a purple-pink tinge to long views at this time of year, the colour augmented by sunshine but lost in a mass of dull browns and greens when cloud covers.   Large, metallic blue and green emperor dragon flies, the size of small birds, were attracted to the ponds scattered across the heath.  They swept back and forth across the water making repeated, aerial, hairpin turns in a constant search for insect food.  Heather spikes dipped momentarily when yellow-striped bumblebees moved among the flower-bells collecting pollen and nectar.

The sandy path levelled out. Heathland now spread extensively on both sides and, together with the grey cloud cover, created a claustrophobic feeling.  Ahead of me was a band of trees with a gate and standing water.  The trees mark a drainage ditch feeding into the Tadnoll Brook, a chalk-stream tributary of the River Frome.  I crossed the ditch on a very solid brick bridge, and was transported to a different world, one of damp meadows and thick rushy grass.  The wet meadow, soggy underfoot, was dominated by untidy stands of shoulder-high marsh thistles with multiple, prolific, spiny stems.  Each stem was topped by a starburst of flower heads, a mixture of shaggy purple flowers and brown and white fluffy seed heads.  Between the thistles, the lemon-yellow cushion flowers of bird’s foot trefoil scrambled through the undergrowth and, as I walked, pale brown grasshoppers soared in long arcs from the rough grass, seeking safety away from me.

Butterflies danced around the unruly thistle flowers like confetti caught in the breeze, pausing occasionally to take nectar.  Small tortoiseshell, marbled white and peacock resembled colourful modernist stained glass and a pair of gatekeepers performed an airborne ballet.   This enclosed wetland felt like a land of plenty, a land of unconstrained, fulsome growth.  Even in high summer, however, the meadow was wet and marshy so that after winter rain the area will become boggy and treacherous.  A group of cows lurked in a corner of the meadow watching me; they help to control growth of vegetation but create further hazards for the unwary walker.

These two very different habitats, the larger lowland heath and the smaller wet meadow make up the majority of the Winfrith reserve as we see it today but the area hasn’t always looked like this.  Until the Bronze Age, this land was covered with forest (birch, pine, hazel, elm, oak) but 3-4000 years ago trees began to be felled exposing the underlying soil.  Nutrients were gradually washed away from freely draining soils leaving behind a relatively acidic surface where heathers and gorse flourished, eventually creating the heath we see today.  This landscape was maintained and scrub encroachment prevented through a combination of grazing by cattle and ponies and by heathland practices such as furze, turf and peat cutting.

Heathland once stretched from Dorchester in the west to the Avon Valley in the east but much has been lost following changes in agricultural practices or through building; a large part of Winfrith Heath was swallowed up when the nuclear research facility was built in the 1950s and still lies behind forbidding fences.  Today, only 15% of the original heath is left but what remains is a very important and rare landscape and part of Dorset’s history.  Its importance as a special habitat supporting rare species such as the Dartford warbler and the nightjar is recognised by its designation as a Site of Special Scientific Interest but the heathland is still threatened directly or indirectly by development.

But did I get any sense of what Hardy’s Egdon Heath was like from my visit?  Even on a small area like Winfrith, there was a definite sense of isolation in the central part of the heath, and that feeling was only partially lifted when the sun shone and the heath took on some colour.   So, if it’s solitude you are after, then it’s a perfect place.  One person’s solitude is, however, another person’s loneliness and it’s not difficult to see how Egdon might have depressed some of Hardy’s characters.  Neither is the heath a benign environment; care is required in all seasons but in winter, it is bleak, brown and very windy with boggy areas dangerous especially after wet weather.  Having said all that, the heath does have an undeniable grandeur but its very rarity as a landscape nowadays means that we may not know how to react to it.  Perhaps like Hardy’s “survivors” we should simply accept and embrace the heath for what it is, foibles and all.

Winfrith Heath lies to the west of Gatemore Road in Winfrith Newburgh and a Dorset Wildlife Trust information board marks the entrance.

The long-horned bee in Devon – and its endangered friend

South Devon coast looking towards Prawle Point
The south Devon coast looking towards Prawle Point (June 16th 2017)

 

It’s been a good summer. We’ve had some fine weather and I’ve been able to spend time on a beautiful part of the south Devon coast looking for the long-horned bee (Eucera longicornis).  It’s one of my favourite insects and one of our rarest bees and there is a strong colony on the coast between Prawle Point and Start Point where low, soft-rock cliffs meander around headlands, in and out of rocky coves and along seaweed-covered beaches.  I visited this area several times between May and July but my most interesting day was on June 23rd, just after the summer solstice.

It was breezy and warm but partly cloudy when I arrived at the coast.  The sea was a uniform grey-blue although now and then the sun broke through the cloud, creating shimmering areas of white water. I started by following the coast path eastwards along the cliff top from Prawle Point.  The sea-side of the path was fringed with scrub and rough grass along the cliff edge whereas the landward side was fenced and mostly used for arable farming.  Many kinds of wild flower grew along both sides of the path including a few generous clumps of purple tufted vetch scrambling through the scrub. After about a mile of easy walking, the enclosed path reached a gate giving on to a broad, open area, not farmed for some years, as far as I know.

I was completely unprepared for the view that greeted me after I closed the gate.  Here was a meadow where thousands of the small, dandelion-like flowers of cat’s ear moved with the breezes to create a mobile yellow canopy above the grass.  Lower down were many tiny yellow globes of hop trefoil and bright pink semi-circles of common vetch.  This is a paradise for insects and I saw many red-tailed bumblebee workers moving purposefully about the chrome-yellow flower heads.

But that wasn’t all: the area along the cliff edge was a kaleidoscope of purples, yellows and pinks, mostly flowering legumes such as bush, kidney and tufted vetches, bird’s foot trefoil and meadow vetchling, restharrow and narrow-leaved everlasting pea.   The number and variety of flowers was greater than I can remember from previous years, perhaps the warm spring had suited the legumes.

The range of flowers, especially the legumes is ideal for the long-horned bee.  I had seen one or two males back along the enclosed path and now I saw several more, also nectaring on the curving, purple, tubular florets of tufted vetch.   There is something other-worldly, almost primeval about these insects with their yellow mask-like face, orange-chestnut hair (in fresh insects) and their impressively long antennae, resembling stiff black bootlaces and about the same length as rest of their bodies.  They are particularly striking in flight, antennae held so that the bee can negotiate whatever obstacle it meets;  controlling those antennae must involve some impressive micro-engineering.   There were also females about feeding on lemon yellow pea-like flowers of meadow vetchling.  Chunkier than the males, they have shorter antennae and, on their back legs, generous pollen brushes resembling golden harem pants.

I scrambled down a rough track to the main Eucera nest area, a section of reddish, soft-rock cliff, pock-marked with hundreds of pencil-sized holes.  Behind me the sea soughed rhythmically on nearby rocks and an oystercatcher sang its plangent song. Female Eucera arrived at the nest site bringing pollen and nectar to provision their nests but they were not alone and I saw several other bee species that seemed to be using the nest area.

One species I had hoped to see was the very rare Nomada, and I had nearly given up hope when the bee suddenly appeared; I was so surprised, I nearly fell backwards off the rocks.  Like others of its kind, it is wasp-like, with a yellow and black-banded abdomen and orange legs and antennae. It was the pattern of the bands, six yellow bands on a black body that told me that this was Nomada sexfasciata, the six-banded nomad bee, one of Britain’s rarest bees.  This site on the south Devon coast is the only place where it is found in the UK; it is nationally endangered so it was very exciting to see it.

It moved about the nest area furtively as if trying not to be noticed and after looking in to a few of the holes it moved on. Later that day I had more sightings of the Nomada; whether it was the same bee or several I cannot say.  As a nomad, the bee has no nest of its own but lays its eggs in the nest of another bee, in this case the long-horned bee.  The Nomada eggs develop into larvae and take over the nest, killing the host larvae and eating their pollen store.  It depends for its survival on a strong Eucera colony and this one in south Devon is one of the largest in the UK.

Long-horned bees and their Nomada used to be found widely across the southern part of Britain in the early 20th century.  They favour a range of habitats such as coastal soft rock cliffs, hay meadows and woodland rides for nest sites and require unimproved flowery grassland for feeding, being especially dependent on flowering legumes for their pollen sources.  With agricultural intensification leading to a loss of habitat, especially flowers, these bees have been squeezed out and are now confined to a very few sites.

It’s not difficult to see how they could be supported.  At the south Devon site, all that is required is to ensure a consistent source of flowering legumes along the coast, the soft rock cliffs already provide the nest sites.    I recently met Catherine Mitson who is working with Buglife on a project to support the south Devon colony of Eucera longicornis and Nomada sexfasciata  by increasing the number of flowers.  Catherine is very enthusiastic and I have great hopes now for the survival of both the long-horned bee and its nomad.

Have you seen the bee orchids?

There I was, standing up to my knees in the long grass trying to examine a flower, when a woman passing on the nearby path asked, “Have you seen the bee orchids?”  I turned and answered “No, but I was hoping to find them” and she continued “If you go nearly to the end of the reserve by the bridge, there’s a very nice one”.

Aller Brook Nature Reserve in Newton Abbott is a place of contrasts.  It might reasonably be called an edgeland for it is on the edge of the town and the reserve starts where the Brunel Industrial Estate ends.  But it’s more urban than even that implies; the other main boundary of the reserve is the A380 trunk road making its presence felt through the continual loud rumble of cars and lorries speeding between Torquay and Exeter.  Between these two urban barriers is an extended triangular tongue of land with the water of Aller Brook running down the middle in a deep scrub-lined channel – this is the Nature Reserve.

Despite all the noise and light-industrial activity, this reserve is a perfect example of how nature can be coaxed in to a space if it is properly managed.  Kingfishers and otters are reported to visit the Brook and, when I was there, birdsong filled the air, at least when traffic noise allowed.  The main path along the boundary with the industrial estate was fringed with typical May flowers: red campion, cow parsley and brambles, all blooming beneath a thick tree canopy.  On the other side of the path, the Brook was occasionally visible through the scrub shield.

Further along the path, I came across several small areas of grassland managed as hay meadows.  Typical meadow plants were flourishing adding splashes of colour to the muted green grasses. Tall drifts of yellow and white ox eye daisies and unruly purple knapweed grew through the thick vegetation.  Common vetch, dotted with pink pea flowers, and buttery yellow bird’s foot trefoil scrambled through the rough cover holding on wherever they could.  A few common spotted and marsh orchids added a little exoticism.  Along the edge of the brook there were stands of dog rose with their floppy, pale pink petals. With all these flowers about, bees were abundant.

The reserve ends at a bridge where the Brook empties into the estuary of the river Teign between huge swathes of tea-coloured reed beds and shiny pillows of brown mud.  The same reeds form a narrow border to the brook.  The bridge area was the part of the reserve where the Bee Orchids were supposed to be, so I looked very carefully within the grass.  They were quite easy to spot, six fine flower spikes standing about 20 cm above the ground with triple propeller-like, pinkish-violet sepals surrounding their complex flowers.

From the bridge, a path returns along the other side of Aller Brook and, at least at the beginning, the vegetation is quite similar.  Compact tracts of grassland sloped downwards to the Brook; common vetch scrambled through the grass accompanied by a few pyramidal orchids.  This side of the reserve, however, felt more contained with stands of brambles and thick tree cover attempting to mask the nearby main road.  It was still slightly unnerving to see glimpses of cars speeding past at 70 mph about 20 metres away.  Incongruously, near here I found another impressive group of Bee Orchids, five spikes in total, with two growing perilously close to the path edge.

As the reserve narrows, so does the path and for some time I walked along a green corridor beneath thick tree cover with relative shade and few flowers.  Eventually the path emerged into the light near a very busy roundabout and the car park of the Toby Carvery.  A ranger I had met earlier told me to look at the grassy area around the car park.  I had to ask a cuddling couple sitting on the edge of this area if they minded if I wandered around the grass but eventually I found thirteen flowering spikes of Bee Orchids looking very fresh, together with one pyramidal orchid.  This unlikely and rather bleak urban spot has a better population of Bee Orchids than the Nature Reserve itself!

There is something very beautiful and rather weird about the flowers of the Bee orchid when you look beyond the three pink sepals.  The most obvious part is the lower petal, the labellum, largely a rich dark red but decorated with variable, yellow horseshoe patterns.  Either side of the labellum are two spurs with a furry surface.  Above the labellum is a pale green arching structure containing two small yellow balls (pollinia) supported by fine threads so that when the wind blows these vibrate.  Above this pale green structure are two horns.

As the name of the orchid suggests, some people see a bee in the complex structure of the flowers.  They imagine the body of a chunky bee (the labellum, complete with furry extensions) with antennae (the two horns) and wings (two of the sepals).  To be honest, I don’t get this – all I see is a complex and idiosyncratic flower but perhaps I am being too literal.  I showed the pictures to Hazel, however, and she immediately saw the bee.

The apparent resemblance of the flowers to bees is also linked with theories of pollination whereby a male bee sees the orchid “bee”, thinks it is a female and tries to pseudo-copulate.  As it does so, it picks up pollen from the pollinia and when it leaves, disappointed, it tries again on another flower pollinating it at the same time.  In southern Europe, the Bee Orchid is cross-pollinated by bees of the Eucera genus but to me none of these bees looks anything like the Bee orchid.  But anyway, who knows what a bee “sees” and it has been suggested that the odour of the flower is more important in attracting the male bees.  To complicate things even more, Bee Orchids in the UK self-pollinate so they manage without bees.

Visiting a place like Aller Brook I can’t help but reflect on our relationship with nature.   I really like the Aller Brook Nature Reserve, there’s something special about the grassland with its profusion of meadow flowers and the Brook with its resident kingfishers and otters.  I love the orchids.  I can’t, however, help feeling troubled by the urban noise, the proximity of traffic and light industry.  This juxtaposition of modern urban life with some of the real glories of nature highlights our dysfunctional relationship with wildlife.  Is this tiny scrap of land the best we can do?  Surely we should be giving nature a higher priority rather than endlessly building roads and houses?

As I thought about this, Joni Mitchell’s song, Big Yellow Taxi kept coming back to me, particularly the words:

“They paved paradise and put up a parking lot”

Perfect poisons for pollinators – available from your local garden centre

We try to make our garden welcoming for bees by growing flowers that provide pollen and nectar throughout the season. We also have some unkempt areas they might want to nest in and we don’t use any pesticides. I enjoy watching the bees foraging on the flowers as they come in to bloom and currently a large cotoneaster bush is full of small bumblebees buzzing loudly as they feed in the sunshine. It’s been very exciting this year to see bumblebees and solitary bees nesting in the dry-stone walls around the garden.

When we need new plants or compost, there is one local garden centre we use. It has a good range of healthy-looking plants and a very nice tearoom! In early spring, it’s also an excellent place to watch one of my favourite bees, the hairy-footed flower bee (Anthophora plumipes), whizzing about in the greenhouses full of flowers. Earlier this year, on a sunny Sunday afternoon in late March, I noticed that these Anthophora had set up nests in the old brick wall of one of the garden centre’s buildings.

……………………………………………………………

About a year ago, I saw a crowd funding request from the well-known bee-defender and researcher, Dave Goulson from the University of Sussex. He wanted the money to test whether plants sold in garden centres in the UK and labelled as “bee-friendly” actually contained bee-toxic pesticides, applied during production of the plants. I remember being quite shocked to read about this possibility – could I have been buying plants to help the bees that were in fact laced with bee-toxic chemicals?

I wanted to find out more so I got in touch with our favourite garden centre and asked whether they were using neonicotinoid insecticides on their plants. They reassured me that they were not. So far so good. I then asked if their suppliers used neonicotinoids in the compost on the plants they sold. The reply came back “I’m afraid I can’t answer that question without phoning every supplier. Also a few companies we deal with import some of their stock from other European countries. I’m happy to ask my local nurseries when I’m speaking to them.” That’s the last I heard.
…………………………………………………………….

Dave Goulson got his money and went ahead with the analyses. The results of his tests have just been published and they don’t make happy reading;  here is a link to his blog on the topic. He and his colleagues bought 29 pots of flowering plants from well-known garden centres around Brighton (Wyevale, Aldi, B & Q, Homebase). Many were labelled “bee-friendly” and some had the Royal Horticultural Society endorsement “Perfect for Pollinators”.

They analysed a range of pesticides in leaves and pollen from the plants and found that most of the plants contained a cocktail of insecticides and fungicides. In the leaf analysis, only 2 of the 29 plants contained no pesticides. 76% contained one or more insecticide and 38 % contained two or more. 70% of the leaf samples analysed positive for neonicotinoid insecticides, well known for their toxic effects on bees. In the pollen analysis, neonicotinoids were found at levels known to cause harm to bees. So much for “Perfect for Pollinators”.

As a result of his work, B & Q announced that from February 2018 their plants would be neonicotinoid-free. Aldi revealed that they had stopped using neonicotinoids in October 2016, a few months after Goulson’s analyses took place. Neither B & Q nor Aldi  addressed the other chemicals found in the Sussex analysis.

The Horticultural Trades Association issued a statement that I believe is both silly and cynical, basically rubbishing Goulson’s analysis. You can read Dave Goulson’s rebuttal here.
……………………………………………………………….

So, it really is true that when we buy plants to help bees in our gardens from garden centres, we may be unwittingly exposing the bees to harmful chemicals, despite the “bee-friendly” labels. Also, any insect that nips into a garden centre for a feed, especially early in the season when garden centres have an abundance of flowers, may be getting a hit of insecticide at the same time.

So, what do we do if we want to have a bee-friendly garden?

Dave Goulson recommends the following course of action: if you must buy plants, buy from an organic garden centre or, failing that, go to B & Q or Aldi. Better still, grow from seed or swap plants with friends and neighbours.
…………………………………………………………

One point that has not been discussed so far concerns potential effects on humans of these pesticides found in garden centre plants. Earlier this year, I bought some fruit bushes from the garden centre and these now have a nice crop of plump berries. If these plants have been treated with pesticides, and of course I don’t know if they have, then the fruit will presumably also contain these pesticides. This possibility makes me very angry. I grow fruit in our garden so that we can eat chemical free, fresh, good quality produce. I don’t want to ingest insecticides and fungicides with poorly defined toxic effects on humans.

Bees in a landscape

I’ve always loved visiting galleries, discovering what an artist has created, but in the first week of May, the tables were turned.  For the first time, I was on the other side presenting a joint exhibition with my artist wife, Hazel.   We called the exhibition, “Bees in a Landscape”, and it was based around Hazel’s semi-abstract paintings of memorable views from the South West of the UK depicting the local landscape in all its glories.  Alongside the paintings, I showed photographs of some of the bees I have encountered in these same locations.   We hoped that the exhibition would raise awareness of the variety, beauty and importance of these beneficial insects as well as showing how we can all support them.

It was more than a year and a half ago that we agreed to put on the exhibition and throughout 2016 I photographed bees and Hazel worked hard on her paintings.  I didn’t spend hours looking for rare examples, I just photographed the bees that I saw, often in local gardens or when Hazel and I were out walking together by the coast.  It has certainly made me look more carefully at insects and flowers when we go out.

As the week of the exhibition approached there were many things to arrange: had we done enough publicity, did we have enough wine for the Private View, had we sent out all the invitations, would enough people come? Fortunately Hazel has a lot of experience in putting on exhibitions.  When we spoke to people in the run up to the exhibition, we detected a genuine interest in the topic of bees and the landscape which was very reassuring.

Hanging the Exhibition finally finished!

The most stressful time was “hanging” the exhibition.  All the paintings and photos were ready but we couldn’t get in to the gallery until 1730, the evening before the exhibition opened on the Sunday.  There were a few distractions, and it took longer than we expected to decide how to place the work around the gallery and to mount it on the walls, and we had to come back on Sunday morning to complete the job.  In the end, we finished with just enough time to nip home to change and be back to welcome guests for the Private View.

The Private View is one of those special artists’ events that goes with an exhibition.   It’s a chance to invite friends, other artists, and people with a special interest to share a glass of wine before the exhibition is open to the public.  Many people came and everyone seemed genuinely interested and impressed by the work.  We were also very fortunate that, during the Private View, Totnes women’s choir Viva, sang for us creating a magical atmosphere with their beautiful harmonies.  Led by Roz Walker, and dressed in yellow and black, they sang songs about bees based on poems by Rudyard Kipling, Carol Ann Duffy, Vita Sackville-West and one based on the Finnish epic poem the Kalevala.   We were so grateful that they gave their time to come and sing for us.

The Exhibition was open that afternoon and then daily until the following Saturday.  Hazel and I split the stewarding duties which meant we each did a morning or an afternoon in the gallery.  Totnes is a busy place and the gallery is in the centre of town so up to 100 people came in each day.  We both had many interesting and unexpected conversations with visitors and I was very surprised at the warmth and interest shown by people who came to look at the pictures, both landscapes and bees.  On many occasions, I heard the comment:  ” I didn’t realise how many kinds of bee there were in this country and how beautiful they are!”  Hazel found that her paintings evoked memories for visitors: of childhood picnics, happy holidays and even a honeymoon.  The greetings cards featuring images from the Exhibition were also very popular.

On the Tuesday, I took a small group on a Bee Tour of the public gardens dotted around the centre of Totnes.  It wasn’t a very sunny day but we had wide-ranging discussions and were able to see some interesting bees foraging on large patches of comfrey and cerinthe including female Hairy-footed flower bees, early and tree bumblebee workers and a garden bumblebee queen.

Our exhibition was featured on Soundart, a local community radio station.  One of the presenters interviewed Hazel in the gallery and I went to the studio to talk about bees.  This was an interesting experience, if not altogether satisfactory.  After Hazel’s interview had been played, the presenters asked me about the exhibition and about bees which was fine.  When we got on to neonicotinoids, however, the discussion was hijacked by one presenter.  He challenged the possibility of obtaining “evidence” in scientific investigations of complex systems like bees and after his intervention, the bee discussion petered out which was a shame as there were many other aspects we could have covered.

Hazel and I were extremely pleased with the exhibition.  Many people came to look and we had some fascinating conversations.  Several people made special journeys to visit and talk to us.  People went away knowing more about bees.  What more could you we have asked for!?

The Seafront Gardens in Lyme Regis

Mature trees, richly planted borders, gently curving paths, a place to look and a space to think – the Seafront Gardens in Lyme Regis provide both an oasis of calm for humans and a safe haven for wildlife.  Not only that, some of the town’s best views may be savoured from this green space.  Looking ahead, the Cobb can be seen stretching its protective, rocky arm around the harbour whereas, across Lyme Bay, the west Dorset coast rises and falls like a gigantic wave sweeping eastwards over Stonebarrow and Golden Cap reaching, on a clear day, that louring sea monster that is the Isle of Portland.

History of the Seafront Gardens

Just over a century ago, the Langmoor Gardens were opened to the public on the slopes above Marine Parade in Lyme Regis.  The land was bought through a bequest to the town from Joseph Moly of Langmoor Manor, Charmouth and the gardens were named in honour of the donation.  The slopes were known to be unstable and concrete buttresses had been built to prevent movement.  Despite this, there were periodic slippages of mud on to Marine Parade and throughout the 20th century the Gardens continued to move causing distortion to paths and eventually rendering the lower part of the gardens unusable.  In 1962, land to the west of these gardens suffered a catastrophic landslip following a misguided attempt at development and several houses were destroyed.  This land was eventually taken over by the town becoming the Lister Gardens, named after Lord Lister of Lyme Regis, pioneer of antiseptic surgery.  The Langmoor and Lister Gardens now form one large continuous public space above Marine Parade.

Rebuilding the Seafront Gardens

The Lyme Regis Environmental Improvements carried out early in the 21st century provided an opportunity to deal with the unstable geology of the Gardens.  Between 2005 and 2007, major civil engineering works were carried out to stabilise the Langmoor and Lister Gardens which were completely remodelled.  The new design included many planted areas and grassy spaces, gently curving paths that seem to reflect the convexity of the Cobb, and a woodland boardwalk with outstanding views across the harbour and bay.  Facilities for mini-golf, putting and table tennis were also built.

Supporting wildlife was deemed important so before work started, bat nesting sites were sealed to prevent them returning, 2000 slow-worms were caught and rehoused and a 15cm barrier erected to prevent others entering.  The gardens were replanted with salt tolerant, sub-tropical and rare plants as well as native species, taking account of the needs of bats, birds and insects.  Now, a decade later, the Gardens have a mature look and nesting boxes for birds and bats are flourishing.  Visitors love the open space and the new design was recognised with an important national award.

The Seafront Gardens in winter

Mid-winter is typically a low time when weather is poor, plants are dormant and wildlife scarce but when I visited the Gardens in December and January I found surprising activity.  Flowering cherry trees at the rear of the Gardens were covered in frothy pink flowers and close by, two fragrant shrubs were also showing well: winter honeysuckle with its white trumpet flowers filled with yellow-tipped stamens; sweet box, covered with tiny white starburst flowers, dark green fleshy leaves and shiny black berries.  As I was admiring the flowers, several bumblebees flew past, stopping briefly to feed from the cherry blossom.

On the terraced borders above Marine Parade, extensive banks of rosemary were covered in mauvish-purple flowers.  These were proving very popular with bumblebees and even in mid-winter, I saw queens and workers foraging busily, collecting sugary nectar and protein-rich pollen from the flowers.  The queens were large and furry with two prominent buff/yellow stripes and a grey or pale brown tail, the workers similar but smaller and more brightly coloured.   These are buff-tailed bumblebees and their relationship with the flowers is far from one-sided.  The flowers consist of two petals enclosing pollen-loaded anthers that beckon seductively at passing insects.  The lower petals contain darker markings highly visible to bees helping to draw them in. Each bee that feeds collects additionally a dusting of pollen from the overhanging anthers which they transfer to the next flower they visit ensuring cross fertilisation.

But shouldn’t bumblebees be hibernating at this time of year?  That’s what all the books say, but the presence of worker bumblebees collecting pollen suggests that somewhere in the Gardens or nearby there are active nests.  Winter active colonies of buff-tailed bumblebees have also been described in South Devon and in Cornwall as well as other locations in the southern half of the UK.  It isn’t clear why this is happening but perhaps these bees are taking advantage of the British penchant for planting winter-flowering plants and shrubs.  The Langmoor and Lister Gardens with their huge banks of flowering rosemary provide this winter forage for the west Dorset bumblebees.

Support your local bumblebees and they will support you.

Although buff-tailed bumblebees seem to be doing well in west Dorset, many other species of bumblebee in the UK have declined over the past 50 years.  This is bad news because these insects are important pollinators of fruit trees, vegetables and flowers.  The decline is largely a result of the agricultural intensification that has changed the look of our countryside leading to the loss of bee habitat, loss of wild flower forage and the use of pesticides.

We can’t reverse this intensification, but we can all help bumblebees by planting flowers in our gardens and by never using insecticides.  It’s important to choose a range of flowers that provide food for bees throughout the season:  the University of Sussex has a useful guide to bee-friendly flowers.   If we provide flowers, the bumblebees and other kinds of bee will return the compliment, visiting our gardens, pollinating our fruits and vegetables and improving their quantity and quality.

When I returned to the Gardens in early April, I found the rosemary still flowering profusely, showing what an important source of insect food it is.  Other plants were also starting to contribute to the forage, and spring insect species were emerging such as the beautiful early bumblebee and red-tailed bumblebee and the grey-patched mining bee.
