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 (94/100 decline) in eight localities (97/100 decline). Historically its main habitats were arable fields, road and track sides, and heaths, commons and quarries.
