Wild plants from seminatural habitats (meadows, pastures, shrubland, etc) provide numerous ecosystem services (ESs). However, because of land abandonment and reforestation processes, these habitats and the ESs provided by them are declining. The aim of this study was to identify how local people benefit from collecting wild plants from seminatural habitats, in order to link the identified ESs with conservation practices. The research was based on a survey of 85 inhabitants of the Pieniny Mountains (Poland). The results showed that 89% of respondents regularly collected wild plants from seminatural habitats for different reasons. The most common ESs gained from this activity were natural medicine, direct consumption, and food. Furthermore, particular species have crucial meaning for some ESs, such as direct consumption, food, natural medicine, and cosmetic purposes. For others, such as decoration, ritual purposes, or forage, only specific parts or types of plants, such as flowers, herbs, or grasses, are desirable, regardless of species. In terms of households, 38% used ESs from seminatural habitats as an additional source of livelihood. Promoting engagement in activities more adapted to the current economic situation (eg ecotourism and selling processed wild plant products) may be a good solution for using wild plants more profitably (serving as a basis for livelihood), combined with grassland conservation.
