Welsh Woods and Forests, first published by the National Museum of Wales in 1982, was well received, soon went out of print, and for years has been unobtainable.

Preface.

The general features of the development of the vegetation since the end of the last glacial (Devensian) period in the territory now known as Wales have been fairly accurately determined by examination of plant remains from archaeologically dated sites, and especially by pollen analyses carried out over the last fifty years, chiefly on samples of peat obtained from bogs at various places in upland and lowland sites.
