Combining the latest information from modern and ancient Irish botanical studies, Flora Hibernica describes the very special landscape and plant combinations of this damp and diverse island. It describes, chapter by chapter, the plants associated with the specific habitats of Ireland such as the seashore, woodlands, boglands, etc. Regional variations within habitat zones are included, with particular attention given to plants unique to each habitat. The particular combinations of light, water and nutrients are also described. Current external influences such as agricultural practices, land use and disease also play a role and this is examined. Each chapter is profusely illustrated in colour.
