A large pattern of willows out of the collection of the nursery Tulln and a lot of Salix caprea, collected from different sites and elevations were tested as browsing substitute for lacking broad leaved trees and shrubs to avoid impact on forest trees. In experimental plots on different sites and elevations from collin up to subalpine, 74 different species and clones were tested (about 30 000 plants). The result compiled from five functions, assessed in a 10 steps-scale for each quality as: favourable browsing material, production of browsing, frost-sensibility and percentage of the plants that took roots after planting, proved a quality-index that indicated a rank-list. Compiling this, a list of recommanded willow species is published.
