Abstract Identifying the vegetation and topographic variables influencing isotopic variability of xylem water forest remains crucial to interpret predict ecohydrological processes in landscapes. In this study, we used temporally spatially distributed stable isotopes measurements from two growing seasons examine temporal spatial variations their relationships with a Luxembourgish temperate mixed forest. Species‐specific were observed during both higher for beeches than oaks. Principal component regressions revealed that tree diameter at breast height explains up 55% isotopes, while species 24% variability. Topographic had marginal role explaining (up 6% elevation). During drier season (2020), detected influence on lower signatures wetter (2019). Our results reveal dominant across forested area suggest patterns arise mainly size‐ species‐specific as well availability‐dependent use strategies rather heterogeneity. The identification key has critical implications representativity isotopes‐based catchments studies.
