Ten days ago I spent the day bioblitzing with my friend Hilary at Amelia Trust Farm (with their permission, of course). Hilary volunteers there so was keen to see what we might discover around the grounds.

The habitats were a mix of woodland, arable fields, and flower and vegetable gardens, though we kept to the various footpaths, only looked at the fields from the fence lines, and didn’t venture far into the vegie patch. As previously, Hilary surveyed the plants and I did everything else. For a late summer’s day, in a site full of noisy families, I thought my total of 59 species was respectable enough. Here are some of the things I spotted …

170702 Square-bashing SS9073 (1)

A few days ago I posted about my square-bashing adventure near Llanbeder, in Gwent. Hilary and I have now also square-bashed another under-biodiversity-recorded 1-km square, this time near St Brides Major in Glamorgan.

As the seagull flies we were within a kilometre of the sea and the geological substrate was very different, so the habitats we surveyed were more diverse. One public path led us down a heavily wooded driveway to an old house, another ran between the edge of that same woodland and fields sown with cereal crops (and there the hogweed was flowering which greatly improved my insect tally), and the third took us over paddocks of rough unimproved grassland, with patches of low rushes, all bordered by a wild old hedgerow.

Interestingly, this time Hilary’s plant list was about 20% lower than that from our previous square (though she still had around 80 species), whereas my list of everything else was about the same percentage higher (at around 100 species of insects, fungi and lichens, molluscs, etc).

As I wrote yesterday, with very little fungi to be found our Glamorgan Fungus Group foray on Saturday developed into a more general nature ramble. I’m afraid I wasn’t writing down the names of all the various critters and plants we saw so I can’t identify everything in these photos but I can name some.

The first is a Red-headed cardinal beetle (Pyrochroa serraticornis), a very pretty beetle though this one wouldn’t keep still for me. The centipede was the same and I’m afraid I don’t remember its name, though I was told it’s not particularly common. It tickled! I think the little yellow dots are the eggs of the Green dock beetle (Gastrophysa viridula) as we saw a pair mating nearby. The tiny moths on the buttercup flower are Micropterix calthella. The plant with the pink flower is one I actually remembered from my botany walk on Thursday – a miracle! It’s Common Stork’s-bill (Erodium cicutarium). Then we have two different species of snail cosying up together. Once again, I was told the names but didn’t write them down and have forgotten (must do better next time!). This very pretty plant was a new one for me and it has two common names, so you might know it either as Wall pennywort or Navelwort (scientific name Umbilicus rupestris). Next is another beetle, this time a Poplar leaf beetle (Chrysomela populi). It was a gorgeous wee thing, with metallic green thorax and dark red body, almost like an oversized ladybird. And, last but not least, was this rather angry Blood bee (Sphecodes sp.). It was trying to lay its eggs in the holes of mining bees when it was netted and potted up for a quick close-up look.

My favourite moment of the day, though, was when I turned over this log. I particularly loved the little grouping of millipede, pill-bug and slug but these were only a few of the various creatures to be seen. It was just nice to see such biodiversity co-existing happily together. A lesson for us all, I think.

An under-recorded square kilometre

After our morning’s biodiversity recording session at Porthkerry and a rather scrummy pub lunch, our SEWBReC team took up the challenge of how many species we could discover in a one-kilometre square that borders Cardiff Airport, a square where only 15 species of anything had previously been recorded. Well, even a desert has more life in it than that, and we had fields and country lanes edged with hedgerows to explore so off we set.

Some of the hedgerows had recently been savagely trimmed and, though sunny, it was blowing a gale so conditions weren’t exactly perfect. But we are a dedicated team! We scanned and we scoured, we probed and we combed, we turned over and peered under, we inspected and we scrutinised. And at the end of two hours we had a preliminary list of 85 species, with some uncertainties to be verified, some ambiguities to be resolved and some experts to be consulted. What a thoroughly enjoyable, eminently satisfying day it was!

Each month SEWBReC provides maps and information about poorly recorded 1km squares in south east Wales, in the hope of filling in the gaps in their maps. If you live in the area, or even if you’re just visiting, you can help fill those gaps. See here for more information.

Bioblitzing Cwm Saerbren

Each summer my local biological records centre, SEWBReC, runs a series of biological recording field days, partly to introduce members of the public to the world of biological recording, allowing them to rub shoulders with wildlife experts and learn species identification skills, and partly to record the biodiversity of particular areas. Last Thursday I went along to the field day-come-bioblitz at the Cwm Saerbren Woodland, adjacent to the small town of Treherbert at the top of the Rhondda Fawr Valley.

This assumed unicorn was the star of the show!

Though the turnout from the locals was disappointing (not a single person!) and despite the sometimes heavy rain (a common feature up the Valleys), we had a great day. With the SEWBReC crew, a couple of guys from Natural Resources Wales, and a few of us volunteers from the Mary Gillham Archives Project, we stomped around the trails of Cwm Saerbren, recording all we saw. And, after meeting up back at the town to identify and write up our afternoon list and then filling up on hot chips from the local takeaway shop, we also got out with the bat recorder and had moth-attracting lights running to see what flying critters we might find. All up, once everything is IDed, I reckon our list will be well over 200 species. Not bad for a day’s work!

Welsh biodiversity: Heath Park

This is the last, but by no means least, day of Wales Biodiversity Week, and today we’re checking out the biodiversity of another of my locals, Heath Park.

160612 heath park (1)

Once upon a time (in the 1830s), the Lewis family built a great mansion (Heath House) on this land (since demolished – where the Miniature Railway and neighbouring carpark are now) and the present park was part of their estate (you can read more here). Today, the 37-hectare site is owned by Cardiff Council, and contains sports fields, courts and playgrounds, a large carpark (also useful for visitors to neighbouring Heath Hospital), large fields for picnics and dog-walking, a mature woodland and two ponds.

Part of the woodland is very damp so, as you can see from my photos, it’s ideal for fungi, even in the summer months. And there is also a rather smelly stream, the Nant-y-Wedal, which had a surprising abundance of wildlife amongst the vegetation adorning its banks. Heath Park was an unexpected biodiversity hot spot, so we have a bumper number of photographs which seems a fitting way to close Wales Biodiversity Week for 2016.

Welsh Biodiversity: Colonising the walls

Here’s something a little different for day five of Wales Biodiversity Week. This is not a specific location – it could be at your house, at the bottom of your garden, in the street where you live, in the middle of a city or in the depths of the countryside.

160608 colonising wall (1)

Stone and brick walls are all around us, and they frequently offer superb examples of a biodiverse environment in miniature. The roots of enterprising plants, like ivy and ivy-leaved toadflax, seek out the tiniest cracks and crannies to establish themselves, as do the many varieties of the garden-escapee Campanula species, which are providing magnificent displays in shades of lilac, blue and purple on the walls here in Cardiff right now. On the damper sides of walls and along the bottoms ferns, mosses and lichens make themselves right at home. Bees, birds and ants frequently nest in the larger holes, as do the occasional rats and mice, and a damp crevice at ground level can make the perfect home for a toad.

And then we have the smaller critters – bees and butterflies often bask in the sunshine on walls; slaters, millipedes and snails inhabit the dark spaces between stones and old bricks; and spiders find the gaps convenient places to string their webs. When you’re next out walking, don’t ignore the walls – take a closer look. You might be surprised what you find.

Long live Biological Diversity!

Tomorrow it will be 24 years since the Convention on Biological Diversity was adopted by the United Nations. To commemorate that momentous day back in 1992, 22 May is now celebrated as the International Day for Biological Diversity. Around the world, events of various kinds – from seminars, exhibitions and leaflets to more hands-on programmes of tree-planting – are organised to promote awareness of the importance of biodiversity, to spread the word that a high variety of plant and animal life is crucial in all habitats.

160521 biodiversity (10)

For my personal celebration, I visited a local nature reserve to see what species of plants, animals, insects, molluscs, etc I could find. And what a treasure trove there was waiting to be discovered! I’ve included some photos here to show you how diverse the area is but I haven’t yet identified everything I saw. I am slowly working my way through my 400 photos. And, as it’s extremely important to record what can be found around us, as a responsible Citizen Scientist, I will also be entering my records into the database of the local biological records centre.

So, here’s a challenge for you. Head out tomorrow, 22 May, and see what you can find in your local park, nature reserve, or even your own garden … and don’t forget to record what you see.
