| Abstract: |
Understanding how polluted ecosystems self-regulate in response to contamination is important for developing nature-based solutions for environmental management. However, plant species identification with the highest role in environmental management remains a major challenge. This study applies ecological principles to identify and assess plant indicators for environmental management in Pb-Zn and Mn mining polluted ecosystems. A total of 234 plant species were recorded, of which key indicator species were identified using indicator species analysis (ISA) and validated through generalized linear models (GLM). Macaranga pustulata, Leucosceptrum canum, and Hypoestes triflora were identified as key indicators in lead-zinc-polluted environments and Morus macroura, Woodfordia fruticosa, and Eremochloa ciliaris in manganese-polluted environments. Phytoremediation assessments showed that H. triflora hyperaccumulates Pb, Zn, Cd, Cr, and Ni, and E. ciliaris accumulates Cr, Cu, Cd, and Ni (bioconcentration factor, translocation factor, and bioaccumulation coefficient values >1). Macaranga pustulata, M. macroura, and W. fruticosa demonstrated strong phytostabilization potential against different heavy metals. These results were further validated by generalized linear mixed models (GLMM), which measure a significant relationship between heavy metal pollution and plant bioaccumulation traits. This study presents a systematic ecological approach for appropriate plants selection for environmental management and recommends the integration of these indicator species into restoration and sustainability programs. |
