Transhumance

Transhumance is the seasonal movement of people with their livestock between fixed summer and winter pastures. In montane regions (vertical transhumance) it implies movement between higher pastures in summer and lower valleys in winter. Herders have a permanent home, typically in valleys. Only the herds travel, with the people necessary to tend them. In contrast, horizontal transhumance is more susceptible to being disrupted by climatic, economic or political change.
