After five years of protracted drought and water-related dieback and mortality, the coastal chaparral ecosystems of the Santa Monica Mountains have finally received increased precipitation. As a co-dominant plant species in this region, Malosma laurina (common name Laurel Sumac), provides an important indication of environmental change. This study examines the effect of the increased precipitation of the 2016-2017 rainy season on potential recovery from drought-induced dieback in M. laurina. This study shows a significant increase in tissue hydration levels and photosynthetic production of dieback plants during post-drought recovery (2017) and between irrigated control sites and dieback sites.
