With much less of my time available for natural history since 24th December, I’m making the best of it by staying local and broadening my taxonomic horizons. In fact, today I have spent the whole day studying the wildlife of our back garden and didn’t even make it down to the far end until just before dark! But I have literally left no stone unturned. I have been spurred into action by Andy Musgrove’s “1000 1ksq challenge“: the challenge being to find 1000 species in your chosen 1km square during 2013. It’s a pan-species challenge: invertebrates, vertebrates, plants, fungi, the lot.
I’ve been seriously impressed at how many species people have already racked up for their squares, with Seth Gibson topping the table at the end of January with a mighty 248 species. I’ve also been seriously impressed at the way so many of the participants are taking a truly pan-species approach and boldly tackling Britain’s biodiversity in its entirety. So, the 1000 1ksq challenge has aroused my competitive spirit, and shamed me into trying to identify things that I normally ignore (like lichens, mosses, earthworms, springtails, etc.). Here are today’s results.
First a few photos, then my species lists for today.
Just the ‘famous five’: Armadillidium vulgare, Oniscus asellus, Porcellio scaber, Philoscia muscorum and Trichoniscus pusillus/ provisorius.
Geophilus insculptus – a tick! Common and widespread species.
Microplana terrestris – identified by comparing to Brian Eversham’s photos on flickr. Pretty sure Brian has shown me this species in the past but it wasn’t on my list, so a tick!
Earthworms: identified using the iSpot keys. A completely new group for me and I was amazed at how many species occur in the garden. I identified three but saw at least two others which defied confident identification.
Lumbricus castaneus Chestnut Worm
Lumbricus rubellus Redhead Worm
Eisenia fetida Brandling Worm. A banded worm, common in our compost bin, and curiously malodorous when handled.
Slugs: the MolluscIreland site is very useful for slug identification, with Roy Anderson’s expert ID tips and his photos.
Deroceras invadens (was panormitanum) – thanks to Christian Owen for bringing me up to date!
Arion hortensis/distinctus – still not sure about these.
Arion rufus – with a bright orange foot fringe. Exhibiting a rocking response, which should be less strong than Arion ater though I’m in no position to judge that.
Leistus spinibarbis (Carabidae)
Notiophilus biguttatus (Carabidae)
Tachyporus hypnorum (Staphylinidae)
Lobrathium multipunctum (Staphylinidae)
Xantholinus linearis (Staphylinidae)
probably Tomocerus minor (thanks to Dr Peter Shaw)
Bryum capillare – leaves became “corkscrew-like” when dry.
Brings me up to a mere 117 species for my square.
