Water and land interrelate in surprising and ambiguous ways, and riparian zones, where land and water meet, have effects far outside their boundaries. Using the Malheur Basin in southeastern Oregon as a case study, this book explores the ways people have envisioned boundaries between water and land, the ways they have altered these places, and the often unintended results. The Malheur Basin, once home to the largest cattle empires in the world, experienced unintended widespread environmental degradation in the late 19th and early 20th centuries. After the establishment in 1908 of Malheur National Wildlife Refuge as a protected breeding ground for migratory birds, and its expansion in the 1930s and 1940s, the area experienced equally extreme intended modifications aimed at restoring riparian habitat. Refuge managers ditched wetlands, channelized rivers, applied Agent Orange and rotenone to waterways, killed beaver, and cut down willows. "Where Land and Water Meet" examines the reasoning behind and effects of these interventions, gleaning lessons from their successes and failures.
