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.
