Vegetation & Biogeography of The Sand Seas Of Arabia [PDF ebook] 

First published in 2005. Although most of the wealth of Saudi Arabia“s flora lies in the wetter and hilly south-west of the country, the sand seas are covered by a relatively diverse range of plant species, with several distinctive plant communities. This is the first book to consider and analyse, both quantitatively and qualitatively, the patterns, nature, and communities of the vegetation of the sand seas, using new techniques. The result is a sound, complete and readable analysis of the vegetation of the sand seas, and one which will be of particular use to biogeographers, ecologists, environmental scientists, planners, conservationists, and those interested in the preservation of Saudi Arabia“s natural heritage.
