Forest and bog vegetation in the Endriejavas environs

Diana Raudonienë, Darius Raudonius

Two vegetation types–woodland and grassland–prevail in the forest area of Skroblë forestry. The woodland occupies 2408.3 ha or 69.7% of the forest area. The grassland occupies 1001.1 ha or 30.3% of the forest area, including 20.5% covered by bog vegetation.

The woodland consists of coniferous and deciduous forests which are divided into 20 forest types dominated by Myrtillo-oxalido-Piceetum and Myrtillo-Piceetum stands, which are typical of the entire Ţemaitija (Samogitian) region. The spruce stands of this type occupy 29.0% of all woodland area in the region studied. Pine stands making 22.2% follow after the spruce stands. The most often spread broad-leaved species are drooping birch (Betula pendula) and black alder (Alnus glutinosa). Birch and black alder stands cover, respectively, 16.3% and 11.4% of the total woodland area.

The grassland is occupied by the wetland community with three type bogs: high moor, transitive type moor, and low moor, where the oligotrophic vegetation type prevails (81.7%). Here 24 plant species have been inventoried. The mesotrophic vegetation type makes 10.2% with 41 species inventoried. The eutrophic vegetation type (8.1%) is scattered in small plots (1.1 ha, in average) with 29 species inventoried.
The region studied was found to have 152 plant species. Myrtillo-oxilidosa spruce community contained 54, Carico-sphagnosa pine forests – 39, Caricosa black alder stands – 48 herbaceous and suffruticous species. The bog community was found to contain 69 plant species. Moreover, 8 plant species (including 5 species of the Lithuanian Red Data Book and international significance) to be protected have been detected in the area studied. Maintaining the necessary regime (by limiting human impact), conditions to protect the rare or less rare plants are favourable.
