The paper presents the analysis of changes in two beech forest communities in the Kołowskie Parowy nature reserve (NW Poland). Within 21 years the frequency and cover of most species significantly decreased, including typical taxa for shady deciduous forests. Analysis of ecological indicator values showed that species richness is strongly correlated with light availability. The results suggest that passive protection promoted in Puszcza Bukowa forest brings negative effects for vascular plants biodiversity
Forest communities of the “Bór” reserve near Głogów Małopolski on the Kolbuszowa Plateau. Fragmenta Floristica et Geobotanica Polonica 10: 93–117. Kraków. PL ISSN 1640 629X. ABSTRACT: This study describes the forest communities of the “Bór” reserve situated in the northern part of the Kolbuszowa Plateau. The reserve protects old part of the Sandomierz Forest. The investigation was conducted using Braun Blanquet method. Six forest associations and four forest secondary communities were distinguished. Leucobryo Pinetum, Querco roboris Pinetum, Tilio cordatae Carpinetum betuli, Fraxino Alnetum are characterized fairly good naturalness and Ribeso nigri Alnetum, Luzulo pilosae Fagetum are degenerate associations. This paper presents the list of interesting and legally protected species and real vegetation maps.
The structure of carabid assemblages was studied in the Holy Cross Mountains, in stands of Luzulo pilosae-Fagetum lowland acidic beech forest (LAB), Dentario glandulosae-Fagetum fertile Carpathian beech forest (FCB), and Dentario enneaphylli-Fagetum fertile Sudeten beech forest (FSB) in 2002. Carabid beetles were collected using Barber's pitfall traps with ethylene glycol in monthly cycles from May to September. A total of 4260 individuals representing 28 species were caught. The highest similarity was calculated for the LAB and FCB assemblages (P=0.54), while the FCB and FSB assemblages were the least similar (P=0.39). The highest diversity was recorded in the FSB assemblage (H'=2.06), and the lowest in the assemblage of acidic lowland beech stands (LAB) (H'=1.45). The dominant species were Carabus violaceus in the LAB sites, Carabus glabratus in the FCB sites, and Carabus hortensis in the FSB sites. The most uniform distribution of individuals between species was seen in the FSB assemblage (0.76) and in the FCB assemblage (0.74), while the LAB assemblage was highly non-uniform in this respect (0.53) Trapability was lowest in LAB (0.36) and highest is FSB (0.55). The prevailing zoogeographical elements were Palaearctic species in LAB, European Forest Province montane species in FCB, and European Forest Province species in FSB. The LAB and FCB assemblages were most active in the spring (Fig. 4) and the FSB assemblage reached peak activity in the summer (July). The dominant species types were forest species (habitat preferences), large zoophages (feeding preferences), mesohygrophiles (humidity preferences), and spring breeders (developmental type).
