By 2008, twelve localities had been investigated. At each location we assessed the degree of threats to the wild grapevine. Flowering plants were seldom found. The plants found were localized geographically, and 149 vines were described using the characteristics of shoot types and leaves, using the O.I.V. descriptor list. Morphological differences of the leaf shape, hair or bristle density are high. A few seeds which were found in dry black berries are much smaller in size than the seeds of Vitis vinifera ssp. sativa. From plants that were easily attainable, cuttings were taken with the objective to multiply the Vitis sylvestris and to establish an ex situ collection. In 2008, we repeated the procedure with 54 vines. The state of health of the vines in situ is very good. No fungal diseases were visible, and mites occurred only rarely. In the nursery, some plants were contaminated by mildew.
