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. The book begins with an introductory overview, it then describes, chapter by chapter, the plants associated with the specific habitats of Ireland such as the seashore, woodlands, boglands, etc. Each chapter is profusely illustrated in colour. Regional variations within habitat zones are included, with particular attention to plants unique to each habitat. The particular combinations of light, water and nutrients used are also described. Current external influences such as agricultural practices, land use and discase also play a role and this is examined. One chapter, 'Weeds and Aliens', describes plants which are not part of a clearly defined system of vegetation such as woodland or bog. These plants are the result of human activities, growing in places as contrasting as motorway embankments, old cultivated fields and commercial forests. Examples are dandelion and rhododendron. Finally, conservation issues are considered.
