Abstract

This paper summarizes conservation work carried out on Filago pyramidata L. (Asteraceae), broad-leaved cudweed, between 1993 and 1996 in Britain. It was formerly native in 125 10km squares in about 240 localities. In 1993–1996 it was recorded in eight 10km squares (94% decline) in eight localities (97% decline). Historically its main habitats were arable fields, road and track sides, and heaths, commons and quarries. It has declined in arable field habitats owing to changes in agricultural practices, and from tracks and roadsides because of reduced disturbance. The decline occurred gradually before the 1970s. Populations show marked variations from year to year and marked differences between sites, owing to climate and management. The best conservation management based on practical experience is annual digging or rotavation in early autumn. The plant is under severe threat in Britain; four sites are designated as SSSIs, but two of the four largest populations are unprotected.
