Résumé :	Habitat associations of Meadow Pipits breeding in British upland 1 km and 10 km squares were investigated using data from the British Trust for Ornithology's (BTO) Breeding Bird Survey (BBS, 1994-97), The New Atlas of Breeding Birds in Britain and ireland 1988-1991 and habitat data front the Institute of Terrestrial Ecology's (ITE) Land Cover Survey (1994). Meadow, Pipit density was highest in 200 m sections of BBS 1 km transects containing unenclosed grass moor, heather and bog, but there was no difference in Meadow Pipit density between? these habitat types. Meadow Pipit density (number of individuals per 1 km square) increased with heather cover up to about 7.5 200 NI sections (often per I km square) of heather, but fell thereafter There was a positive association between Meadow Pipit density and the extent of grass moor cover nle ITE Land Cover data gave results that were consistent with the BBS habitat data at both the 1 km and 10 km square scale. There was a non-linear relationship between hill grass cover and Meadow Pipit abundance, which reached a maximum when hill grass covered between 40% anti 60% of a square. Our results suggest that a mosaic of heather, bog and grassland may be the optimum habitat for Meadow Pipits. Recent changes in land management practices may have led to the disappearance or degradation of these mosaics in some areas. Meadow Pipits are widespread and easily counter. We suggest that this species might be a useful bioindicator of changes in heather and grassland ratios that result front land management practices such as grazing and rotational burning, though further research is required.
