There are some arboreous forms of junipers on the north mires. Our investigations are carried out in the north–east territory of the National Park (the mire system “Charonda”, mire «Malaya Chist»), where an anthropogenic influens was weak. This territory is a reserve. Height of the largest junipers is 15–16 m. Considerable part of them is dead. The age of the dead trees is about 135–150 yrs, the trunk diameter is 22–23 cm, year increase is 0,65 to 0,8 mm. Now living arboreous junipers are seen in the different variations of associations Pinus sylvestris – bog subshrubs – Sphagnum. Arboreous forms grow on
the eutrophic mires too or on the peat, where eutrophic or fire layers are under
the mesotrophic or oligotrophic vegetation. Usually the layer of coals can be found 30–40 cm below the surface. Junipers grow near streams, because its
sites have to be draining. The juniper prefers sunny sites (canopy density is
0,2–0,3). It is necessary to protect and support the sites of arboreous forms of
junipers. Notion is, that there are many potential sites for arboreous junipers on the mires of this National Park.
