Lardon Chase, the Holies and Lough Down is a National Trust countryside property in the English county of Berkshire.

Since it was acquired by the National Trust, the land has been managed by a mixture of scrub clearance and cattle grazing, so as to encourage the growth of chalk-loving plants.

The Holies is a woodland fringed grassy coombe which is separated from Lardon Chase and Lough Down by the B4009 road from Streatley to Newbury.

[7] The slopes of the property form one of the largest remaining areas of chalk grassland in the county and support a wide range of flowers and butterflies.

Plants found in the grassland include autumn gentian, clustered bellflower, blue fleabane, vervain, common rock-rose, horseshoe vetch, kidney vetch, marjoram, yellow-wort, purging flax, wild carrot, chalk milkwort, stemless thistle, eyebright, mouse-ear hawkweed, salad burnet, ragwort, wild thyme, hairy violet, squinancywort, hawkweed ox-tongue, common spotted orchid and pyramidal orchid.
