Plant diversity conservation issues and challenges: A review

Abstract

Significant conceptual changes have occurred over the past years in plant conservation, with major methodological advances incorporating modern techniques, technology, and disciplines. The global, national, and regional loss of biodiversity is a multifaceted issue affecting social, economic, organizational, political, scientific, and communicational scenarios. The identification of root causes is key to preventing biodiversity loss. India's diverse ecosystem supports various needs, including food, medicine, clothing, and shelter. Spatial biodiversity assessment is important for prioritizing and monitoring mechanisms and efforts in the context of land use, land cover change, unprecedented overexploitation, uncontrolled pollution, and alien species invasion. Odisha, an eastern Indian state, is rich in natural resources, with tropical moist, and dry deciduous forests covering remote areas of many districts, north-south-western hills, plateaus, and isolated pockets. Conservation efforts have expanded with protected areas, Red Lists, ex-situ facilities, wild plant accessions, and some developed species recovery programs. The conservation community is concerned about how to respond to the continuously depleting bioresources. Conservation prioritization focuses on protecting socioeconomically, medicinally, and environmentally significant species and living communities, regions of high species richness and endemism, and active functional ecosystems. The present review explores how to address sustainable biodiversity conservation practices and natural ecosystems aligning with UN Sustainable Development Goals No. 13 and 15.
