A Palaeoecological Study of Raised Mires in the Humberhead LevelsBased on the author's doctoral thesis, this study is the first of the Thorne and Hatfield Moors Monographs. Brian Smith looks at the development of the Humerhead Levels through pollen analysis, stratigraphic evidence and radiocarbon dating. The conclusions that he reaches trace changes in the vegetation of the Thorne and Hatfield Moors, the impact of agricultural activities and woodland regeneration. |
