If you’ve been following my ‘wild’ life for a while, you’ll remember that, in August last year, I went on a reptile ramble at the Wildlife Trust of South & West Wales’s Parc Slip Nature Reserve. Well, last Wednesday our team of trusty Mary Gillham Archives Project staff and volunteers went for another ramble, partly because we enjoyed the last one so much and partly as a way of farewelling the lovely Natalie, a university student who’s been working with us since last September. Though tinged with sadness at saying goodbye to Nat, we had an exciting ramble.

I thought perhaps the persistent drizzle might mean we wouldn’t see many reptiles but I was wrong. In fact, the reverse might actually have been true – the rain may well have encouraged the beasties to stay put under their refugia – except, that is, for one large adder, which I almost stepped on, as it was lying in the grass close to one of the shelters. So, though we didn’t see any lizards this time, we saw more adders, grass snakes and slow-worms than last year. Oh, and the bird’s-nest-shaped dried-grass vole nests under some of the refugia were really cute too.

‘Dedicated Naturalist’: Sessile or pedunculate?

A snippet from my volunteer work on the ‘Dedicated Naturalist’ Project, helping to decipher and digitise, record and publicise the life’s work of naturalist extraordinaire, Dr Mary Gillham. This is an extract from a piece called ‘The British Oak’, written for the Cardiff Naturalists’ Society newsletter, September 1991.

Oak is Britain’s national tree. Hearts of oak were our ships and an oak tree appears on the head of the Cardiff Naturalists’ Society notepaper. Yet how many of us can tell the two native British oaks apart – or even realise that there are two? …

We have the Lowland Oak, [in Wales] predominantly in the Vale of Glamorgan, and the Upland Oak, predominantly on the Coalfield hills. If you live along the South Border Ridges backing Cardiff – Pentyrch or thereabouts – you will have both, and also a wide range of hybrids between, so you may be excused a certain degree of confusion.

The Lowland or Pedunculate Oak has stalked acorns and unstalked leaves [as in my photo, left below]. (A peduncle is a flower of fruit talk and the name applies to these.) The ‘proper’ name was formerly a neatly descriptive Quercus pedunculata until some egg-headed boffin decided to change it to Quercus robur, which seems to mean very little.

The Upland, Durmast or Sessile Oak has stalkless acorns, sessile, or sitting directly on the woody twig, and stalks to the leaves, which taper to the base instead of terminating in two ear flaps [as in Mary’s photo, below right]. The ‘proper’ name of this was Quercus sessiliflora until (probably the same) taxonomist changed it to a meaningless Quercus petraea.

These scientists do so like to make things difficult for us. Well, yes, so does Mother Nature. I, too, live on the Border Ridges, so my oaks have stalks to both acorns and leaves. That’s the sort of thing which happens with all this indiscriminate sexual intercourse!

Partly as a training exercise in wildlife identification, partly as a reward for all our hard work to date, and partly as a fun way for our team to get together, our Mary Gillham Archive Project volunteers were treated to a reptile ramble at Parc Slip Nature Reserve yesterday. And it was fantastic!

160818 reptile ramble (4)

Led by friendly and knowledgeable Wildlife Trust officer Lorna, we explored the research and conservation areas where members of the public don’t normally get to wander. With the excitement palpable and a huge sense of anticipation from us onlookers, Lorna used her trusty snake stick to lift up the reptile refugia (sheets of corrugated iron or heavy plastic under which the reptiles frequently shelter) to see what we could find. Though her initial efforts proved unsuccessful, we did eventually get lucky and were very excited to see one very small, young Common lizard (which scuttled away far too quickly for a photo so my lizard photo here is from another day), a Grass snake (which also slithered away far too quickly to photograph), an Adder and 4 Slow-worms. Success! And a great day out, thanks to the conservation efforts of the wonderful folks who work and volunteer at the Wildlife Trust of South & West Wales.

‘Dedicated Naturalist’: Scientific names

A snippet from my volunteer work on the ‘Dedicated Naturalist’ Project, helping to decipher and digitise, record and publicise the life’s work of naturalist extraordinaire, Dr Mary Gillham.

160505 Scientific names

When project officer Al Reeve sent round his monthly volunteer newsletter, he attached this image of the many and varied scientific names we volunteers have been typing up from Dr Mary Gillham’s records. It makes a pretty picture but these things are the stuff of volunteer nightmares! Seriously, what was Linnaeus thinking when he invented binomial nomenclature?

Take, for example, the Eurasian wren, a delicate and tiny bird but its scientific name, Troglodytes troglodytes, makes it sounds like a huge stomping dinosaur. Admittedly, the double-barrel names are easier to remember. There’s Pica pica the Eurasian magpie, Buteo buteo the Common buzzard and Anser anser the Greylag goose.

Troglodytes troglodytes, Anser anser and Turdus philomelos

I feel sorry for the rather unfortunately named Turdus family of true thrushes. There are more than 50 family members, with names like Turdus pilaris the Fieldfare, Turdus merula the Blackbird, and Turdus philomelos the melodic Song Thrush.

Then there are the plants with girls’ names, or should that be girls with plant names? Whenever I type Prunella (as in Prunella vulgaris, the herb Selfheal) I always think of Prunella Scales, the actress who played John Cleese’s exceedingly patient wife in Fawlty Towers, and, though it’s not spelt the same, Silene dioica, the pretty wildflower Red campion, reminds me of singer Celine Dion. And there are plenty more: Veronica, Iris, Lotus, Viola …

160505 Herb Paris

Then there are the misnomers. You might quite reasonably expect names beginning with Trifolium (tri = three, folio = leaf) to have three leaves, except that plants are often not true to their names: witness Trifolium repens, which can, if you’re lucky, be a four leaf clover! Or there’s Paris quadrifolia, the supposedly four-leaf Herb Paris (shown above), which can have from 5 to 8 leaves.

It’s enough to drive a volunteer to drink, so I’ll end with my favourite cocktail, Sambucus nigra. Cheers!

‘Dedicated Naturalist’: Brown rats

brown rat, Cardiff, Dr Mary Gillham, Rattus norvegicus, volunteering

A snippet from my volunteer work on the ‘Dedicated Naturalist’ Project, helping to decipher and digitise, record and publicise the life’s work of naturalist extraordinaire, Dr Mary Gillham.

Love them or hate them, you have to admire Mary’s poetic description of the brown rats (Rattus norvegicus) she saw during a walk along the banks of the River Taff, between the Queen and Wood Street bridges in Cardiff city centre, on 27 October 1979.

Sleek brown rats obviously well fed can be viewed from a little riverside grandstand where the human scent above the expected level instigates only momentary peering of beady eyes and twitching of whiskers. Rats have acquired their inauspicious aura only by being carriers of human diseases and frequenters of human sewers. Whose fault? Ours or theirs? Viewed dispassionately here their weavings between the straight sturdy canes of Japanese knotweed resembles that of a jaguar in a primeval forest, their more intricate passage through tall cocksfoot like lions in elephant grass. There are pickings in plenty, both local and river-borne.

I have retraced Mary’s path along this river bank many times in 2016 and not seen any rats. Good thing or bad thing?
