4. RESERVES FOR THE PROTECTION OF WOODLAND ASSOCIATIONS, AND FOREST TYPES. a) Pine and spruce forests (Vaccinio-Pinetum), and (Piceetum) In these reserves old stands of pine and spruce, that are remnats of the extensive ancient forests, are being protected and constitute interesting material for genetic study. Some reserves were made specially for the protection of different types of coniferous forests. Most commonly the protected pine and spruce stands occur as pure forests, however there are some where these species are mixed with others. An interesting race of pine, with a narrow crown, has been placed under protection as the »Maly Borek« reserve — (10) (90 ha) in the Augustöw Forest. — In this reserve there are also excellent individuals of Betula verrucosa, which characteristically have very clean boles. One of the most valuable fragments of original pine forests is protected in the »Czarnia« reserve (11) (88,7 ha), in the Kurpiowska Forest, Forest District Myszyniec, where some pine specimens are more than 200 years old. Also in the »Surowe« reserve 2 ha (12) of the same Forest District a pine stand (about 250 years old) and a spruce stand (100—130 years old) are being protected. In the Zwierzyniec reserve (13) (41 ha) remnants of the Kurpiowska Forest are being protected in the Forest District Slawki — a pine-spruce forest (150—170 years old) with an admixture of other tree species (400 years old oaks). An interesting race of pine, characterised by intensive growth is being protected in the »Pusta Wielka« reserve (14) (800 m elevation) in the Krošcienko Forest District (2,6 ha). A very well conserved Carpathian coniferous forest (Piceetum tatricum) is being protected in the Gorce reserve (15) on the slopes of Turbacz Mt. and in the »Romanka« reserve (16) in the Eastern Beskid, Forest District Jelešnia (34 ha), in which many trees are up 100 years old. The interesting, and internationally famous race of lower elevation spruce is being protected in the »Butorza« (17) reserve of the Rycerka Forest District and in Istebna (18) with an area of 30,7 ha. In south-western Poland fine spruce stands mixed with beech are being protected on an area of 10 ha in the »Morawa« reserve (19) of the Kotlina Klodzka. b) Fir forests. A fir forest (Abietetum polonicum) is being protected in the Swietokrzyskie Mts. chiefly in the Swiety Krzyz National Park. Particularly interesting populations of Abies alba mixed with beech are being protected in the »Obrocz« reserve (20) of Central Roztocze, Forest District Zwierzyniec (70,97 ha) on the north-eastern extremities of the species range. In this reserve fir trees of considerable size, 46 m in ht. and 300 cm in diameter, can be found. One of the most valuable forest reserves was established on the »Bukova Göra« (21), near Zamojski´s Zwierzyniec, in south-eastern Poland on the loess soils. |
