Functional Matrix: A Conceptual Framework for Predicting Multiple Plant Effects on Ecosystem Processes (2003, background): “The presence of trees in arid areas can further enhance salinity because canopy interception and evaporation reduce the water available to flush salts out of the rooting zone (Munzbergova & Ward 2002).”
Effect of spatial scale on factors limiting species distributions in dry grassland fragments (2004, unknown): “1996; Münzbergová & Ward 2002).”
Scattered trees are keystone structures – Implications for conservation (2006, background): “Similar mechanisms also have led to increased salinity in some natural ecosystems such as the Negev desert in Israel (Munzbergova and Ward, 2002).”
