“…Older woodland was formerly managed as coppice or coppice-with-standards although these practices have been abandoned for many decades except in a few nature reserves. Earlier management of forests has probably influenced· the present day composition; for instance, Jones (1953) noted that Polytrichum jormosum was formerly frequent in coppice. Neglected sweet chestnut (Castanea sativa) coppice exists in a few places on acid soils (e.g.…”

“…About ten small valley mires survive on the Plateau Gravel and Eocene areas in the south and two others at Greenham Common and Caesar's Camp (86NE) have been destroyed since Jones's (1952Jones's ( , 1953 flora was published. Individual valley mires are listed under the account for Sphagnum magellanicum below.…”

“…Regrettably Jones (1952Jones ( , 1953Jones ( , 1955 and Bowen (1968) give example localities only, or omit them altogether, for numerous commoner bryophytes which have, therefore, had to be excluded from the analysis. Table 7 also omits taxa which have been newly described or taxonomically redefined since about 1960, including Metzgeria temperata, Bryum bicolor and its allies, the Bryum erythrocarpum complex except B. radiculosum, B. subelegans, Dicranella staphylina (and D. varia with which it was confused earlier), the Fissidens viridulus complex and Pohlia lutescens.…”

“…Early Berkshire records were published by Boswell (in Druce, 1886), Druce (1922), Napier (1910), Hurst (1916) and Monckton (1919). The first comprehensive bryophyte flora was that of E. W. Jones (1952Jones ( , 1953Jones ( , 1955 covered both . A synopsis of Jones's records, together with a modest body of data collected subsequently, appeared in The Flora o/Berkshire (Bowen, 1968).…”

A bryophyte flora and atlas is presented for the vice-county of Berkshire. This is based on records collected systematically from 5 x 5 kIn grid squares since 1982 and data from earlier studies. 434 taxa have been recorded since exploration began in about 1660, of these 55 have not been refound since 1980 or earlier. The maps reveal strong distribution patterns in response to calcium carbonate content of the soil, variations in precipitation, the presence of ancient woodland and the influence of atmospheric pollutants. A comparison of the contemporary flora with that revealed by earlier studies reveals a marked decline in frequency of bryophytes of earth-capped walls, heathland, calcareous grassland, mire and fen, arable field taxa and epiphytes. At least seven liverworts and 50 mosses appear to have increased in frequency. These changes can be attributed to the loss and damage of heathland by scrub invasion and burning, agricultural improvement of natural grassland, cessation of coppicing, early ploughing and fertilizing of arable land, acidification and weathering of substrata by pollutants, loss of mature elms through Dutch Elm Disease and invasions by aliens. Atmospheric pollution has caused losses, particularly of epiphytes, but with falling S02 pollution in the east some taxa appear to be rapidly recolonizing lost territory.

“…Jones (1953) stated that in the Oxford area it often occurs in deep crevices of banks, limestone pits or brickwork, where closely overhung by herbage. Near Cambridge I have found it in brick culverts carrying streams beneath roads and farm tracks, and Paton (1961) reported it from this habitat in Hampshire.…”

Native acid rock is extremely local in the region, but is still found in one field at Bradenham, Buckinghamshire, and in a few places near Ashdown Park and Lambourn in west Berkshire. Here, as in north Wiltshire, there are relict Eocene boulders known as 'sarsens', and these may harbour a rich cryptogamic flora corresponding to the Parmelion conspersae of James et al. (1977). Notable lichens found here include Aspilicia caesiocinerea,
