Data set ID:
Data are pre-dawn water potential for leaves collected from plants subjected to five possible precipitation treatments: -80%, -50%, control (0), +50%, +80%.
The objective is to assess water status of plants in response to precipitation manipulations.

Pre-dawn water potential was measured for mesquite and black grama leaves periodically throughout the growing season. Individual leaves were collected and water potential was measured using Scholander type pressure bombs. One leaf for each species was collected from each plot selected for measurements.
