Pollen analysis is a powerful method for reconstructing historical ecosystems. Preserved pollen grains in lakebeds and peat bogs offer detailed records of past plant communities. Since plant distribution is tightly linked to environmental factors such as temperature, rainfall and humidity, identifying the types of pollen present in different layers of sediment can reveal how ecosystems have responded to natural climate fluctuations over time and how they might react in the future.
