                         gradients that correlate with soil-water and nutrient 
                         availability. Data on soil water for the Amazon Basin are scarce, 
                         limiting the possibility of distinguishing between soil and 
                         soil-water influences on plant composition. Aim: We tested a new 
                         proxy for water table depth, the terrain height above nearest 
                         drainage (HAND), as a predictor of composition in trees, lianas, 
                         palms, shrubs, and herbs and compared HAND to conventional 
                         measures of height above sea level (HASL) and horizontal distances 
                         from nearest drainage (HDND). Methods: Plant-species composition 
                         in 72 plots distributed across 64 km2 of lowland evergreen terra 
                         firme forest was summarised using non-metric multidimensional 
                         scaling (NMDS). NMDS scores were regressed against estimates of 
                         HAND, HASL and HDND. Results: Plant composition was highly 
                         correlated with the vertical distance from water table, capturing 
                         up to 82% of variation. All life forms showed highest turnover 
                         rates in the zone with seasonally water-saturated soils, which can 
                         extend 350 m from stream margins. Conclusions: Floristic 
                         composition is closely related to water table depth, and HAND 
                         appears to be the most robust available topographical metric of 
                         soil-water gradients. Brazilian conservation laws protecting 
                         30-m-wide riparian buffers are likely to be too narrow to 
                         encompass the full zone of highest floristic turnover and may be 
                         ineffective in safeguarding riparian plant diversity.  2014
