In a few reserves populations of ash and black alder, both having great economic importance are being protected. The most important ones are the »Starozyn« reserve (39) in the Plaska Forest District, in the Augustowska Forest, (183 ha) where 80—120 year old stand of ash hornbeam and black alder being protected and the »Kozi Rynek« (40) reserve, (146,6 ha) where the same species are growing together with spruce. In western Poland, in Wielkopolska a few reserves were made» Debina« (41) (30,4 ha) in area in the Durowo forest District; »Sarnice« (42) (2,5 ha) in the Czeszewo Forest District, a forest primeval in type with rich species admixture including ash, alder, maple, sycamore, birch, oak and lime in the same Forest District is »Lutynia« reserve (43,4 ha) (43) and in voivodeship Lodz »Wolörka« reserve (44) (3,5 ha).

Reserves of mixed forests, 20 in number protect forest communities concentrated mainly in the lowland and upland regions of the country. There are relatively small forest fragments with an area of a few to 15 or so hectars each, in which often monumental trees are designated. Some of these reserves characterise the associations of primeval forests. Due to their diversity as regards species composition, age and tree size they can also have an importance in the protection of economically valuable forest populations. Some of them are presented in Table I.
