Support us in Frankfurt/Main with the maintenance of the database African Plants Photo Guide
Senckenberg maintains a digital identification guide and photo database of african plants, which is widely used internationally. Help us to maintain that database.
You help us with rating and uploading images. You do not need any special knowledge, although simple computer skills and basic experience with the internet are an advantage. However, an interest in plants and their form is helpful. Further training will be provided on site.
