Short summary

This study analyzes seasonal biomechanical traits of marram grass at two coastal dune sites using monthly field and lab data from 2022. Observed differences in density, leaf length, and flower stems were found to be wind-independent and transferable across sites. The results support surrogate model development for numerical and physical experiments alike, where using live vegetation is impractical. Results address the knowledge gap on how vegetation influences dune stability and erosion resistance.
