Land Use, Fragmentation, and Impacts on Wildlife in Jackson Valley, Wyoming, USA

  • Jill M. Lackett
  • N. Thompson Hobbs

The Jackson Valley in northwest Wyoming, USA, contains 4,000 km2 of public and private land used for agriculture, grazing, forestry, recreation, conservation, and housing (Figure 6-1). The region offers an unusually complete history of changes in land uses and their implications for access to heterogeneity for humans, domestic livestock, and wildlife. Unlike most of the other case studies in this volume that focus on impacts of fragmentation on people and livestock in classically pastoralist systems, this chapter will include a discussion of impacts of fragmentation on wildlife in an area that is increasingly being developed.

In this chapter, we will discuss three historical periods: the period before settlement by Europeans, the rise of agriculture, and the emergence of recreation-based economies. For each of these historical periods we will discuss land tenure and use, economic forces, and sources of fragmentation. We will then discuss the consequences of fragmentation for wildlife in the region. We close by describing how the Jackson case (and the more general situation in agricultural areas of western North America) fits the model of progression of land use and land tenure described in this book, a model that predicts consolidation of privately-owned land following its fragmentation. We also show how the Jackson case departs from that model in a fascinating way.
