Local plant knowledge of farmer's families in Napf-region, Switzerland

This contribution presents preliminary results of an ongoing PhD project which aims to explore linkages between plant diversity and local plant knowledge in the Napf‐region in Switzerland. The central part of the Napf is a cultural landscape listed in the Federal Inventory of Landscapes and Natural Monuments of National Importance. Cultural Domain Analysis was used to get an overview of known and used plant species. In total 51 family members of twelve farmer families were asked to list indigenous plants, followed by semi‐structured interviews about the use of the species. Roughly 400 wild and cultivated plant species were listed. The most frequently mentioned were Taraxacum officinale agg. and Rumex obtusifolius L.. Mentioned use categories, with declining frequency, were food, medicine for humans and animals, decoration, handicraft, toys and customs. Statistical analysis on the influence of demographic factors like age, gender, education, cultural background and farming system on plant knowledge revealed that age is the most important factor to explain knowledge variation
