Abstract

1. The climatic, physiographic and edaphic conditions of the Snaefell area of the highlands of Iceland are described. 2. An account follows of the principal plant communities, viz. myri, colonized stream fans, willow mo, knolly mo, geiri, stream banks and such open types of community as those of rock outcrops, screes and hilltops. 3. The types of succession leading up to these communities are described, with particular emphasis on such geomorphological topics as the origin of pans in myri and the effects of erosion by wind, solifluction and snow. 4. The interrelationships between the different lines of succession are considered. 5. The most conspicuous components of the animal population are described and an account is given of an attempt to give the survey of the ground fauna a numerical basis. 6. The animal and plant populations of the Snaefell area are compared (a) with those of the surrounding highlands (as typifying a semi-glaciated district) and (b) with those of the highlands of Great Britain. From these comparisons an attempt is made to discover how far the fauna and flora of the Snaefell area help in constructing a picture of post-glacial Britain.
