Sydney Johnson Film Archive

by Joan Andrews



Sydney Vivian Johnson died on 7 May 2014, at the age of 95. Syd never married but had many friends. He worked for BP Oil, at their former-refinery in Llandarcy, but film cameras were his love.



I got to know Syd through the Merthyr and District Natural History Society, where he was a friend and contemporary of Mary Gillham OBE. Mary at that time worked for the Extramural Department of Cardiff University and, as part of her job, organised expeditions to study natural history. Mary and Syd thus were together on many occasions passing on their own considerable expertise. Syd was a film camera enthusiast and recorded what he saw on varying media as they became available, and showed his films at many local meetings. As well as being an excellent naturalist, Syd was interested in industrial archaeology and recorded many scenes of locally-important industries – especially around the Neath Valley where he lived.



I have two memories to share. Firstly sitting down on Gower with Syd, both trying to take a picture of a fulmar, and Syd warning me just in time of their nasty habit of regurgitation. The other occasion, on the Isles of Arran in Galway Bay, where Syd joined in every walk – but always delicately balancing his very heavy camera up and over the numerous stone walls.



His close friend Mike Jones shared many of his archaeological expeditions, such as a particular visit to an old lightship at Britton Ferry that had served at the D-Day landings. These outings continued almost to his death and usually ended with a fish and chip supper, and in Syd bemoaning that “all his pals were going”.



Members may wonder why the Cardiff Naturalists’ Society is commemorating this man. It is because we were gifted his entire film archive. It is a very mixed bag, with some on very old film stock. Many of the films are of industrial archaeology and mention the Neath Antiquarian Society, of which he was a life-long member. Mary Salter, Mike Dean and I have listed all the material, and we have had two films of good quality digitalised: ‘An Island of Birds’, which we will show at the Monday 18 April 2016 meeting, and one about the Glamorgan Canal. He was certainly the best amateur filmmaker I have known and I hope we can preserve his legacy in some small way. If any members have knowledge of Syd, or expertise in his field, we would really value your advice.

Seashore Safaris with Judith Oakley

Last night (15 Feb 2016), marine biologist Judith Oakley gave an illustrated talk to the Society about Seashore Safaris, focusing on the intertidal life of the rocky shores around The Gower in South Wales.

Judith is the author of the book ‘Seashore Safaris’ (Graffeg) and, through her work with Oakley Intertidal, organises educational Seashore Safaris for all ages to visit the intertidal zones at low tide. The programme for Summer 2016 (and further information about the initiative) can be found on the Oakley Intertidal Facebook page, the website http://www.oakleyintertidal.co.uk/ and at the bottom of this post.

In her presentation, Judith started by presenting ‘The Seashore Code’. Best practice, for example, is not to use nets at all, place overturned boulders and rocks back where you fund them, to place only one creature at a time in a bucket or tray for observation, and to always put it back before the water in that bucket or tray becomes too warm or oxygen-depleted.

At low tide, a number of zones on the shore can be identified in terms of their different plants and animals, with biodiversity increasing the closer you get to the low water mark (where organisms have the lowest exposure to the air).

A range of micro-habitats occur on rocky shores. We explored three of them through Judith’s photographs: rockpools, overhangs, and under boulders.

In rockpools, we were introduced to creatures such as the common starfish that feed on mussels by prising their shell apart with their suckers and everting their stomach through their mouth into the shell to digest their prey. Chameleon prawns were shown to change colour to match different backgrounds; while grey sea slug has evolved immunity to the stings of sea anemone, and after consuming them it utilises those stings to defend itself. Another sea slug (noted generally as being far more interesting than their terrestrial counterparts) was shown tucking into a breadcrumb sponge. The beautiful stalked jellyfish (red, about 1.5cm across) is rare around The Gower, and one of the species that you can report to help improve knowledge of seashore biodiversity, for example, through the Marine Life Information Network (MarLIN) – see the sealife survey page at http://www.marlin.ac.uk/

Under overhangs at low tide, a range of exotic-looking creatures can be found. Here the humidity can remain high and the bigger overhangs are almost like mini-caves (so a torch could be handy). Here Judith introduced us to the soft coral known as dead man’s fingers – each finger being a colony of the soft coral made up of myriad tiny animals called polyps. Sea anemones, sponges, barnacles, sea firs, and other organisms are also attached to this unique micro-habitat; where you may also find the UK’s largest sea slug, and creatures such as long-legged spider crabs, sea cucumbers, and baked-bean sea squirts.

It is always fun to look under boulders (but remember to carefully put them back as they were afterwards) to find the creatures underneath. Judith showed us photos of some of the rich biodiversity that can be encountered, such as cowries, squat lobster, pipefish (with their male brood pouches), urchins and various crabs.

We will all be looking more closely next time we find ourselves on a rocky shore.

A Year in the LIFE of RSPB Cymru

At the 28 January 2016 meeting, Daniel Jenkins-Jones talked to members of Cardiff Nats about RSPB Cymru’s varied activities during 2015. He summarised developments on RSPB Cymru’s nature reserves, briefly outlined the organisation’s political lobbying work, noted its ‘off-reserve’ conservation work, and looked at the ‘Giving Nature a Home in Cardiff’ campaign.

The RSPB owns and manages around a dozen nature reserves in Wales, and manages a number of other sites. Daniel presented figures for breeding pairs of birds in 2015 at these sites. There was bad news, in the alarming decline seen in the UK for seabirds and other bird species, but good news in that conservation action on RSPB Cymru reserves is protecting and increasing bird populations.  

Landscape work to extend wetland areas (using machinery funded through landfill tax) at the RSPB Malltraeth Marsh nature reserve on Anglesey, for example, has increased the lapwing population, and also resulted in a pair of hen harrier nesting in the area (the last breeding pair here was seen in 1974). Ynys-hir, a wetland area on the Dyfi estuary in Ceredigion, also has breeding lapwing, and notable populations of, among others, redshank, pied flycatcher, wood warbler and Greenland white-fronted geese. At Lake Vyrnwy, the largest site managed by RSPB Cymru, habitat management is helping moorland-breeding birds such as hen harrier, black grouse and merlin (the latter species has suffered a crash in numbers in the UK).

On Ramsey Island, RSPB Cymru’s work is helping protect a number of seabirds whose numbers are generally in decline; breeding success has been recorded, for instance, for guillemot, razorbill, kittiwake, Manx shearwater, storm petrel and chough. Daniel described how eradicating rats on Ramsey Island, by employing a New Zealand company who used baited peanut butter, was a key action in reducing breeding bird mortality. At nearby Grassholm, part of the UK’s third largest gannet colony can be seen online thanks to RSPB Cymru (Google ‘gannet cam Grassholm’). The organisation does important work releasing gannets trapped by the plastic waste (mainly originating from the Marine fishing industry) that they bring back to their nests. In 2015, 50 gannets were freed (550 in total have been rescued in the last few years). With work on several other reserves noted, the scale and variety of RSPB Cymru’s conservation work during 2015 became apparent.

Political campaigning is an important part of RSPB Cymru’s work, and they have a regular presence at the Senedd - the home of the National Assembly for Wales. 2015 was an important year in this respect, with the drafting of the Environment (Wales) Bill, which will put into place legislation for planning and managing Wales’ natural resources in a more integrated and sustainable way. However, conservation organisations considered that, under the influence of Natural Resources Wales, it placed too much emphasis on business and not enough on nature; Daniel noted that the first draft did not even mention nature, though lobbying by RSPB Cymru and other NGOs has put nature into the Bill’s final wording. Last year, the RSPB was also very active in formulating and promoting the Nature and Wellbeing Act. In addition, RSPB Cymru were involved in advisory work with farmers, and around 100 case studies ranging from small-scale to large-scale projects such as the Swansea Tidal Lagoon.

Following a report that showed the low level of engagement with nature among Welsh school-age children, RSPB Cymru has been committed to more educational work. One new initiative in 2015 was the ‘Giving nature a home in Cardiff’, which involved hands-on practical visits to 90% of Cardiff’s schools. This was funded with the help of the plastic bag charge in Wales.  As part of the initiative, RSPB Cymru undertook the ‘Tape’ project in Bute Park, with the help of Arts Council Wales funding. This installation, which involved large amounts of non-sticky tape strung around trees to build a raised structure that could be entered, was visited by around 74,000 people (10,000 venturing inside). All the plastic is being recycled to make wild flower planters to put around Cardiff.

Daniel concluded his talk with a look at how people can help RSPB Cymru, through volunteering (not just habitat management, but also in administration roles). The easiest way to support the organisation’s work, however, is to join. Follow the link for further information:

Cardiff Birdwatch

Report by Mike Dean


About 12 intrepid bird watchers met at the north end of Roath Park Lake on Sunday, January 10th 2016. Conditions were far from ideal as it was raining and very wet underfoot from the rain the night before. We first walked around the woods to the north of the lake and then around the lake itself but by the time we returned to the cars, heavy rain and hail commenced so it was decided not to move on to a second location but to return to the comfort of our homes.

However, we were able to see some notable birds, namely – a Great Spotted Woodpecker, Long Tailed Tits, Redwings together with the usual residents of the wood all to the accompaniment of a Song Thrush. On the lake we saw a Pochard, Little Grebes, Tufted Ducks together with the Mute Swans, Coots, Moorhens & Mallards.

Thanks must be given to Linda & Rob Nottage for organising the event in spite of the inclement conditions.

Rambles

text and photos by Bruce McDonald

A few snippets from some recent rambles.

Beetles on a Gower beach
First Whiteford on Gower, which Cardiff Naturalists' last visited to look at beetles a few years back with Steve Bolchover. A fine day in mid-June this year and the same stretch of sand on the edge of the dunes around SS 4428/9517 was productively revealing. The key appears to be to find a larger plank of wood or branch or tree trunk that is just above the recent high-tide mark but below the dunes. Lift slowly and see what lies beneath. The black beetle, Broscus cephalotes, was found quite easily. They either stayed put or went scuttling off across the beach.


Broscus cephalotes

Not so common but also in evidence was Nebria complanata, sufficiently rare to warrant its own Species Action Plan. It feeds on sandhoppers at night and is variously referred to as the Strandline Beetle (as is Broscus cephalotes!) or Beachcomber Beetle. Have your camera ready if you find one under timber as they often burrow down into the sand.


Nebria complanata

Running around on the surface of the beach in the same area was the Dune Tiger Beetle, Cicindella hybrida, and helping to procreate the species were the two below. They can travel at speed so are not always easy to photograph but these two had other things on their minds.
 
 
Dune Tiger Beetle (Cicindella hybrid)

Galls on Gower and at Culverhouse Cross
Whilst on Gower another gall to add to the existing 'collection'. This I take to be Aulacidea hieracii described as having ovoid or elongate swelling of the stem, green at first then hard and brown. This was on several Hawkweed plants in the car park at Oxwich Bay.

 
Gall on Hawkweed

The Copthorne Hotel at Culverhouse Cross roundabout, Cardiff, has the usual common shrubs and trees but the Hawthorn was showing examples of the gall shown below. It has been a struggle to identify this one and any expert views would be most welcome. Photographic comparison with web images suggests Gymnosporangium as a possibility - caused by a fungus. Whereas clavariiforme is usually associated with Juniper which does not seem to apply here, this could be confusum.
 
 
Gall on Hawthorn

... and not far away some Holm Oaks, Quercus ilex, with the gall shown below. Again, information on galls affecting this oak is limited, the main reference being to Aceria ilicis. caused by a mite.
 

Gall on Holm Oak

The next challenge is the gall causing these swellings on the leaves of Hop Trefoil, Trifolium campestre, on which I have again drawn a blank. There is little enough on possible galls for this plant, one candidate being the mite Dasineura trifolii but the description of this refers to folding of the leaves along the mid-rib which is not that evident here. Again, any insights from readers would be helpful. 


 
Gall on Hop Trefoil

Orchids and Pearly Everlasting
A walk near Treorchy in late June was something of a revelation. A forestry track which starts just north of Cwmparc SS 9472 9617 by a metal barrier is worth trying because of the profusion of Southern Marsh orchids. Up to this point we had been walking through heavily sheep-grazed turf and the only plant you tend to find is Tormentil, Potentilla erecta, although it was interesting to note that Lady's Mantle, Alchemilla sp., was growing in clumps suggesting it is unpalatable even to the voracious sheep. Once into the sheep-free area the botany was a revelation. One of the usual suspects was Pearly Everlasting. The following extract is from a field trip in 1994 to Kenfig by The Wildflower Society:
 
'Then we came to a first record for Britain, Anaphalis margaritacea, Pearly Everlasting, which was recorded in the South Wales valleys in the seventeenth century and is now spreading over Wales.'
 
It is certainly quite common in the Valleys, is visible on the edge of the M4 around the Pyle turn-off and turned up on Coppet Hill near Goodrich growing under bracken. Despite its local ubiquity it is almost completely ignored by wildflower books. Wouldn't it be nice to know more about this plant?

 
Pearly Everlasting

A smattering of Common Spotted Orchids, Dactylorhiza fuchsii, was eclipsed by the Southern Marsh Orchids Dactylorhiza praetermissa which appeared to favour the damper runnels alongside the forestry track and stretched for a mile or more giving one of the best displays you are likely to come across in this part of the world.
