“…The western arm would have formed a similar large-scale enclosure of limestone plateaux, with optimal conditions for use in winter, enhanced by extensive areas of swampy ground in large basins like the area of the Gulf of Arta, where scrub and shrub vegetation would have provided important winter browse for deer and cattle, and insect infestation in summer would have powerfully stimulated seasonal herd dispersal. Some of the water-retentive soils could also have been important areas of summer grazing, and it is possible that this western coastal region formed an annual system of animal movements and economy at least partially independent of the eastern arm of the horseshoe (Bailey et al 1986a). The eastern arm, however, would not have been viable without the complementary winter grazing of areas near the coast.…”
