more on worms

Here it is, my participant pack has arrived (together with a nice id chart for worms). There are 26 different species of British worm - and there was me thinking there were only two - from an aptly named compost worm to an octagonal-tailed worm. There is even a Black-headed worm.
The survey task is to dig a hole 20x20x10cm and collect all the earthworms for identification, as well as noting foreigners - beetles, flies, bugs, snails, slugs and spiders. Then, followed by some remedial soil characteristics and measurement of pH that's about it - although I still have to work out what the sachets of vinegar and mustard are for.
