. Fifteen soil profiles in the Alltcailleach Forest in NE Scotland have been resampled after almost 40 years. The pH, in 0.01 M CaCl 2 , of the soil has decreased by 0.07 to 1.28 units in 80% of the surface organic horizons and by 0.16 to 0.54 units in 73% of the mineral horizons below 40 cm. The key factors governing increases and decreases in soil pH are changes in ground vegetation and tree canopy, although some effects of acid deposition cannot be ruled out.
