  • Manipulates the timing of seasonal snowmelt in a high-elevation mixed-conifer forest in a Mediterranean climate during consecutive wet and dry years to understand how snowmelt timing effects soil water availability during the summer in terms of depth and persistence
  • Finds the hydrological signal of snowmelt timing was strongest in shallow soil
  • Finds that the effects of snowmelt timing on soil moisture lasted 2–4 months
  • Finds that advancing snowmelt timing by 2–3 weeks depleted shallow soil water by one third
