Conservation biology focuses on the protection, management, and restoration of biodiversity in response to increasing environmental degradation and species loss. In plants, conservation biology addresses the preservation of genetic diversity, species richness, and ecosystem functions essential for ecological stability and human well-being. Habitat destruction, climate change, invasive species, and overexploitation pose major threats to plant diversity worldwide. Conservation strategies include in situ protection, ex situ conservation, habitat restoration, and sustainable resource management. Advances in molecular biology, population genetics, and ecological modeling have enhanced the effectiveness of conservation planning and decision-making. This article reviews the principles of plant conservation biology and highlights its role in maintaining biodiversity, supporting ecosystem services, and ensuring long-term environmental sustainability.

Conservation biology is a multidisciplinary field dedicated to understanding and preventing the loss of biological diversity. In the context of plants, conservation biology aims to protect species, genetic resources, and ecosystems that form the foundation of terrestrial life. Plants support food webs, regulate climate, and provide ecosystem services essential for human survival. Plant biodiversity is currently declining at an alarming rate due to anthropogenic activities. Habitat destruction caused by deforestation, urbanization, and agricultural expansion remains the primary driver of plant species loss. Fragmentation of natural habitats isolates plant populations, reducing gene flow and increasing vulnerability to extinction. Climate change presents a growing threat to plant conservation. Rising temperatures, altered precipitation patterns, and increased frequency of extreme events disrupt plant phenology, distribution, and survival. Many plant species are unable to migrate or adapt rapidly enough to changing climatic conditions, leading to population declines (McNally et al., 2025). Invasive species pose a serious challenge to native plant communities. Introduced plants, animals, and pathogens can out compete native species for resources, alter soil chemistry, and disrupt ecological interactions. Managing invasive species is therefore a critical component of plant conservation efforts. Genetic diversity within plant populations is essential for adaptation and long-term survival. Small or isolated populations often experience genetic erosion and inbreeding, reducing fitness and resilience. Conservation biology emphasizes the preservation of genetic variation to maintain evolutionary potential (Soulé, 1985). In situ conservation involves protecting plants within their natural habitats through the establishment of protected areas such as national parks, reserves, and conservation corridors. This approach maintains ecological processes and species interactions that cannot be replicated elsewhere. In situ conservation is considered the most effective strategy for preserving plant biodiversity (Lindenmayer et al., 2022). Ex situ conservation complements in situ efforts by preserving plant genetic material outside natural habitats. Seed banks, botanical gardens, tissue culture, and cryopreservation are widely used to safeguard rare and endangered species. These methods provide insurance against extinction and support restoration programs. Habitat restoration is an important conservation strategy aimed at recovering degraded ecosystems. Restoration efforts involve reintroducing native plant species, improving soil conditions, and reestablishing ecological processes. Successful restoration enhances biodiversity and ecosystem services. Conservation biology increasingly incorporates scientific tools such as population genetics, remote sensing, and ecological modeling. These tools help identify priority species and habitats, assess extinction risk, and design effective conservation strategies. Evidence-based conservation improves resource allocation and management outcomes (Cowlishaw & Dunbar, 2024).Public awareness, policy development, and community participation are vital for successful plant conservation. Sustainable land-use practices, environmental education, and international cooperation contribute to the long-term protection of plant biodiversity and ecosystem health (Pullin, 2002).
Conservation biology plays a crucial role in safeguarding plant diversity and maintaining ecosystem stability in the face of escalating environmental threats. Through integrated strategies such as habitat protection, genetic conservation, restoration, and sustainable management, conservation biology seeks to prevent plant extinctions and preserve evolutionary potential. Advances in scientific research and technology continue to strengthen conservation efforts, but long-term success depends on informed policies, public engagement, and global collaboration. Protecting plant biodiversity is essential not only for ecosystem health but also for sustaining human life and environmental resilience.
