Knowledge about organismic traits is useful for many different studies in environmental sciences. For example, traits can be used to study the functional diversity of plant communities and competition between species. Furthermore traits of underutilized plants are an important resource for agricultural usage and phytomedical applications. There are large biodiversity data collections which are a potentially rich source of such plant trait data: - Floras describe plant traits with a focus on morphology or habitus relevant for species identification in addition to other characteristics (e.g. health applications). - Complementary topic databases, for example focusing on geographical distributions like Senckenberg's West African Plants [1], provide large image collections which allow additional trait and habitat data to be extracted.
