Controls on meadow distribution and characteristics [chapter 2]

Abstract

Meadow complexes are located in distinct geomorphic and hydrologic settings that allow groundwater to be at or near the ground surface during at least part of the year. Meadows are manifestations of the subsurface flow system, and their distribution is controlled by factors that cause localized zones of groundwater discharge. Knowledge of the factors that serve as controls on groundwater discharge and formation of meadow complexes is necessary to understand why meadows occur where they do and how anthropogenic activities might affect their persistence and ecological condition. In this chapter, we examine physical factors that lead to the formation of meadow complexes in upland watersheds of the central Great Basin. We then describe variations in meadow characteristics across the region and parameters that produce differences in the nature of meadow complexes at basin scales. In subsequent chapters, we examine the geomorphic, hydrologic, and vegetation processes that operate within individual wet meadow complexes.
