Centipeda cunninghamii (old man weed) is a culturally significant plant that is widely distributed across the floodplain wetlands of the Murray–Darling Basin. This short communication combines aboriginal and non-aboriginal knowledge of C. cunninghamii to highlight its importance in river–floodplain systems and to add to the flow-ecology knowledge base for this species. Percentage cover data for C. cunninghamii, collected from the floodplains and wetlands of the lower Lachlan River system from 2014 to 2019 were used and compared with data on time-since-flooding and soil moisture to describe this species’ response to flooding and drying. The results of this study show how the occurrence and distribution of C. cunninghamii in the landscape is related to the occurrence and distribution of inundation and that environmental flows can be used to maintain this culturally important plant.

Centipeda cunninghamii（老人杂草）是一种具有重要文化意义的植物，广泛分布于默里-达令盆地的洪泛区湿地中。这段简短的交流结合了C. cunninghamii的原住民知识和非原住民知识，以突出其在河洪平原系统中的重要性，并增加了该物种的流生态知识基础。使用2014年至2019年从拉克兰河下游河滩和湿地收集的C. cunninghamii覆盖率数据，并将其与自洪水以来的时间和土壤湿度的数据进行比较，以描述该物种对洪水和干旱的反应。这项研究的结果表明，C。cunninghamii的发生和分布 景观中的植物与淹没的发生和分布有关，可以利用环境流量来维持这种具有重要文化意义的植物。
