Field Meeting for spring flowers in Jill's Field, 5 May, 2006 Mary Smith 33 Gaynes Park Road, Upminster, Essex RM 14 2H.I Six people met at 2pm on a beautiful summery afternoon on Friday 5th May, 2006, in Love Lane, Aveley. We set off towards Jill's Field, a wild area of original Thames Terraces with very sandy, low nutrient soil west of Aveley but east of the new A13. Jill Ireland, who lives in Love Lane, is a local naturalist who first drew our attention to this interesting area which she had spotted while walking her dog. Part of it is a SSSI for the geological exposures on the banks of the road cutting, but the plants on top are just as special. Several surveys had already been done in this area a few years ago, but Tim Pyner managed to find several more species of interesting or unusual plants. New finds included Early Hair-grass Aira praecox, Little Mouse-ear Cerastium semidecandrum, Lesser Chickweed Stellaria pallida and Great Brome Anisantha diandra. You will soon realise that of these 4 species, 3 are tiny (hands and knees stuff) while the last is a big chap, rather hard to miss. Most of the plants in Jill's Field are tinyworts, due to the low-nutrient sandy soil, but the Great Brome was a little way away where plants are a bit bigger. While Tim was bottom-up and head down, others were studying the scarce plants already recorded, such as Spring Vetch Vicia lathyroides, Subterranean Clover Trifolium subterraneum, Bird's-foot Ornithopus perpusillus, Changing Forget-me-not Myosotis discolor, and spotting numerous butterflies such as Speckled Wood, Painted Lady, Peacock, Small Tortoiseshell, Common Blue, and enjoying the Sky Larks singing overhead. The nearby woodland in a pit was declared very boring, and so was the ex- grassy area now covered with Goat Willow and Silver Birch. So at about 3:30 we decided to rum around and cross the A13 using the footbridge slightly to the south.
