Metallophyte vegetation on ancient lead-mining sites in the UK. (a) Sparse
cover of Agrostis capilliaris and Silene uniflora on acidic wastes at Goginan lead mine,
central Wales; (b) Continuous metallophyte turf colonising superficial mine workings at
Gang mines, near Matlock, Peak District. The calcareous substrate here and mosaic of
metal contamination levels produce a rich assemblage of metallophytes including
Minuartia verna in the most metal-contaminated areas. Photos: A. J. M. Baker.
