“…For over 30 years in this area spontaneous secondary succession has been observed. The meadows were abandoned at different times, so different stages of succession represented by different types of plant communities can be observed (Faliñska 1991a(Faliñska , 2003.…”

The paper presents results of a study on the response of species growing in experimental gaps in the patches dominated by Carex acutiformis, C. cespitosa and Salix cinerea. The study was performed in a meadow area subjected to the process of succession in the Reski Range in the Bia³owieski National Park. Four patterns of seedlings recruitment in the experimental gaps were distinguished: pattern I great number of seedlings with high richness of species, pattern II great number of seedlings with low richness of species, pattern III low number of seedlings with great richness of species and pattern IV low number of seedlings with low richness of species.

“…The colonisation success of a given species depends on many factors, among others on the floristic combination, space to be colonised, the competition from other colonists, mode of reproduction, type of growth and length of life (Grubb 1977;Faliñska 1991a;Namura-Ochalska 1993).…”

“…Typically, they occur under extreme conditions, or as ephemeral populations invading new areas (Gray et al 1987;Faliñska 1991;Begon et al 1999). Among characteristic features of C. mariscus is its ability to invade the surface of water by forming a floating mat that is expanding towards the centre of the lake.…”

Contribution to the characteristic of Cladium mariscus (L.) Pohl population in the initial zone of floating mat on an oligo-humotrophic lake in north-eastern Poland

In the initial phase of growth in an oligo-humotrophic lake, Cladium mariscus forms a dense and tall sawgrass bed invading the open water in the form of a floating mat. High densities of submerged evergreen perennial stems of C. mariscus, over two metres high and abundantly fruiting, ensure its persistence, and form a natural barrier to the invasion of other species. Dense mats of sawgrass are formed as a result of clonal and rhizome growth. Although diaspore production is abundant under natural conditions, only vegetative propagation of stems was observed. In different variants of the experiment only seeds wintering on stems of mother plants were capable of germinating. Hard seed coats had an important effect on the germination capacity of seeds.

“…At that time, wetland areas that had previously been cultivated with great effort were left to spontaneous development (Lipský, 1995). On a local scale, Falińska (1991) situates the moment of the formation of young alder woods between 30 and 45 y after abandonment. Similarly, Smit and Olff (1998) recorded that Alnus glutinosa started to be dominant after 20 y of grassland abandonment.…”

“…In the past, people drained sites of alder carr (Döring-Mederake, 1990;Ellenberg, 1996) and used them as coppice forests or changed them into meadows and pastures (Brown, 1988;Rybníček and Rybnicková, 1974). In the 20th century, a return towards semi-natural communities of alder carr was mentioned in different parts of Europe (Falińska, 1991;Foster et al, 1992;Güsewell and Le Nédic, 2004). However, knowledge about the mechanisms of succession from wet grasslands to alder carr, as well as the factors driving this process, remain largely unexplored.…”

Keywords:aerial photograph / Alnus glutinosa (L.) Gaertn. / dendrochronology / land abandonment / secondary succession / wetland Abstract • The secondary succession of wet grasslands to communities of alder carr dominated by Alnus glutinosa was recorded in different parts of Europe during the 20th century. However, knowledge of such development of alder carr remains insufficient.• The development of alder carr was reconstructed at five sites in the Czech Republic, using historical aerial photographs and methods of dendrochronology. The aims were to investigate the succession from wet grasslands to alder carr at sites previously intensively managed for agriculture and to find out the role of fluctuations in the groundwater table, caused by artificial drainage channels, in the observed stand dynamics and tree growth.• The spread of forest (i.e., an increase in forest cover) predominated until the 1970s at all sites. This trend was disrupted by a large-scale dieback of forest stands in four of the five sites after the 1970s, followed by an increase in patch heterogeneity, as indicated by landscape metrics. The radial growth increment in Alnus glutinosa has been affected predominately by local environmental factors, probably including the changing degree of waterlogging. Forest dieback was presumably connected with a lesser extent of drainage channels.• Our results indicate that observed successional pathways at sites of alder carr were probably caused by local changes in the groundwater table.Mots-clés : photographie aérienne / Alnus glutinosa (L.)

Toutefois, la connaissance du développement de taillis d'aunes reste insuffisante.• Le développement de taillis d'aunes a été reconstruit dans cinq sites en République Tchèque, à l'aide de photographies aériennes historiques et des méthodologies de la dendrochronologie. Les objectifs étaient d'étudier la succession de prairies humides en taillis d'aunes sur des sites précédem-ment exploités intensivement par l'agriculture et de découvrir le rôle des fluctuations de la nappe phréatique, causées par le drainage artificiel des canaux, et d'observer la dynamique des peuplements et la croissance des arbres.• La progression de la forêt (c'est-à-dire, l'augmentation du couvert forestier) a prédominé jusque dans les années 1970 dans tous les sites. Cette tendance a été perturbée par un vaste dépérissement des peuplements forestiers dans quatre des cinq sites après les années 1970, suivie par une augmentation de l'hétérogénéité des bouquets d'arbres, comme indiqué par les paramètres du paysage. L'augmentation de la croissance radiale de Alnus glutinosa a été affectée principalement par les facteu...
