We will be aiming to record regional rarities in this important, but increasingly degraded, series of ancient woodlands. Several of our target species, such as Melampyrum pratense (Common Cow-wheat), Achillea ptarmica (Sneezewort), Carex pulicaris (Flea Sedge), Eleocharis acicularis (Needle Spike-rush), Genista anglica (Petty Whin) and Pedicularis sylvatica (Lousewort) are now restricted to a very small number of highly fragmented populations and may become regionally extinct in the near future. This meeting is suitable for beginners and for more experienced botanists. Please bring a packed lunch.

Meet at 11:00am outside the Water's Edge Pub, Reservoir Road, Ruislip Common (TQ08648919).
