Plant communities are groups of different plant species that grow together in a specific area. These communities can vary widely based on factors like climate, soil type, and available water. Common examples include grasslands, forests, and wetlands. Each community supports a unique set of plants that interact with each other and their environment. The composition of a plant community can change over time due to natural processes or human activities. For instance, disturbances like fire or flooding can alter the community structure, allowing new species to thrive. Understanding these communities is essential for conservation and ecosystem management.
