Introduction to Botanical Informatics
Botanical informatics is the interdisciplinary field that applies computational and data science techniques to botanical research, plant biodiversity monitoring, and ecosystem management. It encompasses the collection, storage, analysis, visualization, and sharing of plant-related data across scales—from genes to ecosystems. As climate change accelerates and biodiversity loss continues, botanical informatics has become essential for understanding plant responses, predicting ecological changes, and developing conservation strategies. This rapidly evolving field bridges traditional botany with cutting-edge technologies to address complex challenges in plant science and environmental management.
