Opis:
The distribution of Trollius europaeus in the northern part of the Południowopodlaska Lowland was described and a phytosociological study made of the localities where it was present between 2010 and 2012. The condition of all sites where T. europaeus was historically present was also verified. These field studies reveal that the number of sites of occurrence and the abundance of T. europaeus populations have rapidly diminished over recent years. Only 15 populations of the species in the vicinity of 7 sites were confirmed. Trollius europaeus is usually considered a species characteristic of moist meadows of ordo Molinietalia and in the plant community type, Polygono bistortae-Trollietum. In the northern part of the Po³udniowopodlaska Lowland, no meadow sites containing Trollius europaeus still remain according to our survey. All the confirmed stands are situated in deciduous forests of class Querco-Fagetea (Tilio-Carpinetum and Potentillo albae-Quercetum) and moist forest edge communities of ordo Glechometalia. The disappearance of all meadow populations is mainly considered a result of intensification of the agricultural use of these habitats. We suggest that the category of threat to Trollius europaeus is increased on the regional list from VU to EN, and consolidated with further monitoring and active protection of stands where it is present.

Południowopodlaska Lowland
Opis:
Linnaea borealis, the twinflower, is considered a critically endangered species in the Południowopodlaska Lowland. The disappearance of the twinflower is mainly caused by habitat changes resulting from forest management, but also light deficiency due to the increase in canopy cover and growth of the shrub layer (processes of succession). The aim of the paper is to present the actual distribution and phytosociological characteristics of L. borealis in the northern part of the Południowopodlaska Lowland. In this region, only three out of ten known areas of occurrence (Werchliś, Serpelice, Grala-Dąbrowizna) have endured to the present day. The twinflower occurs in pine forest, Peucedano-Pinetum, and mixed forest, Querco roboris-Pinetum, communities. A decrease in the ground cover of twinflower populations was observed in all existing twinflower locations. Although the area covered by the Linnaea borealis population in Werchliś increased tenfold during the last 20 years (from about 200 m2 in 1993 to 1970 m2 in 2013), its cover-abundance according to the Braun-Blanquet scale decreased from 5 to 3. The increase in the area covered by the twinflower population together with the accompanying decrease in cover-abundance is probably not a manifestation of species dynamics but rather a response to disadvantageous environmental changes (growth of canopy cover and shrub layer). Progressive light reduction can initiate the process of fragmentation of a population. A decrease in the cover-abundance of the L. borealis population (from 4 to 2) was also observed in Serpelice. Its area was reduced to half of its original size due to anthropogenic destruction of this location. In the third region, Grala-Dąbrowizna, also the negative effects of competitive species (e.g. Vaccinium myrtillus, V. vitis-idaea) are considered.
