The Evolution and Features of VegetWeb: A Comprehensive German Vegetation Database

VegetWeb serves as a pivotal resource in the field of botanical research in Germany, detailing the evolution of the database since its inception in 1995. Originally established for local access, it transitioned to MySQL in 2001, enhancing its data model with contributions from Vegbank and workshops. The database supports user-friendly queries and displays a range of parameters. It enables easy import/export capabilities for data management and logging, facilitating research on various vegetation types, including Bavarian Mountain vegetation and Fagus sylvatica forests.
