Abstract

Over the past decade, ecologists have sought to better quantify the consequences of changes in ecosystems by focusing on the “ecosystem goods and services” that they provide humanity and the specific ways in which they increase human well-being. These goods and services have been subdivided into “supporting”, “provisioning”, “regulating” and “cultural”. This framework has been further expanded in numerous ways, including identifying options associated with differentiating between location-centric vs. location-flexible stakeholders, between portable and non-portable services, and between fast, patchy ecosystem change versus gradual, homogenous ecosystem change, both of which can be driven by climate change. The critical zone itself provides services that overlap with ecosystem services, and soils are a primary driver of such ecosystem services. Drawing on potential issues within the Jemez River Basin and Santa Catalina Mountains Critical Zone Observatory, we highlight the role of soils in four examples: (1) How will changes in winter precipitation and snowpack affect CZ water resources?; (2) How will changes in drought affect CZ water resources?; (3) How will a snow-rain shift affect CZ productivity- and carbon-related services?; and (4) What will determine post-disturbance recovery and changes in associated CZ services? These examples highlight more generally a central role for soils and associated ecohydrology in determining critical zone goods and services, much in the way that they do for many ecosystem goods and services.
