The decline of transhumance in the west and the implications for private grazing lands: California case studies
The interaction of an arid, topographically complex landscape, colonial and imperialistic aspirations, and the framework of land tenure institutions available to enterprising settlers shaped land ownership patterns in the western US.The resulting improvisation, together with changes in the cost and supply of alternative modes of production and uncontrolled urban sprawl, underlies the decline and loss of traditional transhumance systems of livestock production, particularly cattle production, in the latter half of the twentieth century.The Forest Service manages grazing leases on the majority of high elevation rangelands, and allowed grazing has been declining since the 1920s.There is more than nostalgia for what in comparison to Europe and other parts of the world was in the U.S.a short‐lived tradition.A declining ability to use diverse rangelands through transhumance is a problem for ranchers, but also for land conservationists and ecosystem managers.Rancher transhumance depends on linking private and public ecosystems in a cycle of production, and this connection is being broken.This paper focuses on the relationships with and consequences for private rangelands.Private rangelands are generally on better soils and have more water, and have been shown to in many cases have higher biodiversity and other values than public rangelands (Maestas et al.2001).
