PRESENTED PAPERS 97 Sixteen other MAP species are partly protected (Cetraria islandica, Ribes nigrum, Ononis spinosa, Frangula alnus, Ledum palustre, Arctostaphylos uva-ursi, Viburnum opulus, Polypodium vulgare, Asarum europaeum, Primula elatior and P. officinalis, Asperula odorata, Centaurium umbellatum, Gentiana asclepiadea, Helichrysum arenarium, Convallaria maialis, and Hierochloe australis). Their harvesting is possible in specified amounts and time limits, with the permission of the Provincial Conservatories of Nature. Wild-growing MAPs in Poland There is no detailed documentation so far concerning the distribution of wild-growing MAP species in Poland. The investigations on natural habitats have been made only for some species (e.g. Achillea sp., Centaurium umbellatum, Hypericum sp., Euphrasia sp., Adonis vernalis, Atropa belladonna, Arctostaphylos uva-ursi) and for chosen areas. More thorough studies are currently underway in the Research Institute of Medicinal Plants in Poznań and in the Department of Vegetable and Medicinal Plants, Warsaw Agricultural University (SGGW) (Table 1). They concern geographic location, number of sites, population size, morphological, developmental and chemical traits. For chosen species molecular research is also carried out. Table 1.

In the last few years more than 100 samples of seeds of investigated accessions were transferred to the Polish Gene Bank in Radzików.
