1. The growth of riparian trees in semi-arid regions is influenced by stream flow regime, but the relative importance of base flow and seasonal floods on growth has not been explored. I examined abiotic influences on the growth of Platanus wrightii in four stream reaches in Arizona. All reaches had a bimodal pattern of discharge, but only two had continuous flow throughout the growing season. 2. In two reaches of Sycamore Creek without perennial flow, a large percentage of the annual variation in radial growth rate of P. wrightii was explained by annual and growing season flow rate. Growth was related to these same variables in a perennial reach of Sycamore Creek, but trees maintained higher growth during drought...

Many of the streams and aquifers that sustain Interior riparian deciduous forests in the US Southwest are being dewatered, yet we know little about how the plant communities are being affected by these hydrologic changes. This study found that several measures of biotic integrity, including Platanus wrightii xylem water potential, P. wrightii radial growth rate, tree species diversity, and woody plant wetland indicator scores, varied significantly with ground water depth and fluctuation among nine sites in Arizona. P. wrightii trees had highest productivity, and the forests had greatest compositional diversity, where ground water averaged less than 2 m below the tree base during the growing season and less than...
