Plant ecology is the study of the interactions between plants and their biotic and abiotic environments, focusing on the factors that influence plant distribution, abundance, and community structure. Plants respond to environmental variables such as climate, soil, water availability, and nutrient status, while also interacting with other organisms including microbes, herbivores, and competing plant species. These interactions shape plant communities and drive ecosystem processes such as primary productivity, nutrient cycling, and energy flow. Understanding plant ecological patterns and processes is increasingly important in the context of global environmental change, habitat fragmentation, and biodiversity loss. This article provides an overview of the principles of plant ecology, emphasizing plant–environment interactions, community dynamics, and ecological adaptations that enable plants to survive and reproduce across diverse ecosystems.

Plant ecology examines how plants interact with their physical environment and with other living organisms. These interactions determine where plants grow, how they form communities, and how ecosystems function. As primary producers, plants form the foundation of terrestrial ecosystems and influence the distribution of other organisms. Environmental factors such as light, temperature, water, and soil nutrients play a central role in shaping plant distribution. Each plant species has specific tolerance limits and resource requirements that determine its ecological niche. Variations in these factors across landscapes create diverse plant communities (Tansley, 1993). Soil properties, including texture, pH, organic matter, and nutrient availability, strongly influence plant growth and survival. Soil–plant relationships affect root development, water uptake, and nutrient acquisition, ultimately shaping vegetation patterns across ecosystems. Plant–plant interactions such as competition and facilitation influence community composition and structure. Competition for resources like light, water, and nutrients can limit plant growth, while facilitative interactions, particularly in stressful environments, can enhance survival and establishment (Terborgh, 1973). Plants also interact with animals through herbivory, pollination, and seed dispersal. Herbivores can regulate plant population sizes and influence species composition, while mutualistic interactions with pollinators and seed dispersers enhance reproductive success and gene flow. Microbial associations are essential components of plant ecology (Crawley, 2009). Symbiotic relationships with mycorrhizal fungi and nitrogen-fixing bacteria improve nutrient acquisition and stress tolerance. Soil microbial communities play a key role in nutrient cycling and ecosystem functioning. Plant populations exhibit dynamic changes over time through processes such as recruitment, growth, and mortality. Disturbances including fire, flooding, grazing, and human activities can alter plant communities, creating opportunities for succession and regeneration. Succession is a fundamental concept in plant ecology describing the gradual change in plant communities following disturbance. Early successional species modify environmental conditions, enabling the establishment of later successional species and increasing ecosystem complexity (Sun et al., 2021). Adaptations such as drought tolerance, shade tolerance, and nutrient-use efficiency allow plants to survive in diverse habitats. These traits influence species distribution and competitive ability under varying environmental conditions. Plant ecology provides essential insights for conservation, land management, and ecosystem restoration. Understanding plant community dynamics helps predict ecosystem responses to environmental change and supports sustainable management of natural resources (Farella et al., 2022).
Plant ecology reveals the complex interactions that govern plant distribution, community organization, and ecosystem functioning. By studying plant–environment relationships, species interactions, and adaptive strategies, plant ecology enhances our understanding of biodiversity patterns and ecological resilience. As global environmental change accelerates, plant ecological research is crucial for conserving ecosystems, restoring degraded habitats, and promoting sustainable use of natural resources.
