Climate change is one of the most pressing global challenges of our time, with far-reaching consequences for ecosystems and biodiversity. Among the many affected components of ecosystems, plant biodiversity stands as an essential element. Plants play a fundamental role in maintaining ecosystem function, providing habitat and food for numerous organisms, and contributing to essential ecosystem services. In this study, the impact of climate change on plant biodiversity, including shifts in species distributions, altered phenology, changes in plant communities, and the potential implications for ecosystem stability and human well-being will be discussed.

Climate change is causing significant shifts in the geographical ranges of plant species. As temperatures rise, plants are compelled to move to more suitable habitats, tracking their optimal climatic conditions. Species are migrating toward higher latitudes and elevations, resulting in changes in community composition and plant diversity at different locations. Some species may face challenges in finding suitable habitats for migration, leading to range contractions or even local extinctions.

Climate change is disrupting the timing of essential plant life cycle events, such as flowering, leaf emergence, and seed germination. Warmer temperatures and changing precipitation patterns can lead to shifts in phonological events, causing mismatches between plant phenology and the availability of pollinators, seed dispersers, or other key ecological interactions. For example, if flowering occurs earlier than the arrival of pollinators, it can disrupt pollination and subsequently affect seed production and plant reproduction.

Climate change can also impact plant communities by altering species composition and the competitive dynamics among plants. As some plant species thrive under new climatic conditions, they may outcompete native species, leading to changes in community structure. This can result in the loss of rare or specialized plant species and affect the overall diversity and functioning of ecosystems. In addition, increased temperatures and water stress can favor the expansion of certain invasive plant species, further impacting native plant diversity.

Plant biodiversity is essential for maintaining ecosystem stability and providing essential ecosystem services. Diverse plant communities contribute to ecosystem resilience, as they enhance resistance to pests, diseases, and disturbances. Additionally, plants play a vital role in carbon sequestration, helping to mitigate climate change by absorbing and storing atmospheric carbon dioxide. Changes in plant biodiversity can disrupt these processes, potentially leading to reduced ecosystem stability, increased vulnerability to invasive species, and decreased capacity for carbon storage.

The impact of climate change on plant biodiversity has significant implications for human well-being. Plants provide essential resources such as food, timber, medicines, and fibers, upon which human societies depend. Changes in plant distribution and abundance can affect crop yields, impacting food security and agricultural productivity. Furthermore, shifts in plant communities can disrupt traditional knowledge and practices of indigenous communities that rely on specific plant species for cultural, medicinal, or spiritual purposes.
