Plant Associations in Moorland Districts

Nature volume 71, pages 257258 (12 January 1905) | Download Citation



DURING the last four years systematic observations have been made on the distribution of the various associations of vegetation covering the moorland region lying to the east of the Vale of Eden.1 The boundaries of each plant association have been traced out in the field and laid down on the six-inch Ordnance map, and reduced to the one-inch map for publication. The factors governing the distribution of plant associations over such a limited area are mainly edaphic, although the differences in altitude, which amount to about 2500 feet in the area in question, produce changes in the vegetation which are chiefly due to climatic conditions. Much of the vegetation at present covering cultivated areas in Britain owes its distribution to artificial agencies, edaphic and climatic factors being to a great extent masked. The more remote moorland districts of the north of England and Scotland, however, give opportunities for studying plant associations the distribution of which is chiefly determined by edaphic and climatic factors, the artificial factors due to the influence of man being secondary.
