“…In the community of Filipendulion alliance, the shrub species (Alnus glutinosa, Salix cinerea, Padus avium) have all been noted, therefore we assume that intervention is required to stop further development of willow and alder shrubs. A similar process of succession was observed in the meadows described by other authors [49][50][51][52].…”

The aim of this study was to provide a phytosociological and ecological characterization of meadow communities in the Łąki w Komborni Natura 2000 site (SE Poland), assess the trends in their transformation, and indicate the major threats impacting on their conservation. The study was conducted in 2015-2016. Three types of meadow communities were distinguished (alliances Molinion, Arrhenatherion, Filipendulion), due to the absence of the species characteristic for associations. The species richness noted per relevé differed significantly between the types of meadows (Kruskal-Wallis test: H = 21.65, p < 0.05). The highest floristic biodiversity (H' = 2.99) was noted for the meadow patches classified as in the Molinion alliance and the lowest (H' = 2.50) was found for the patches from the Filipendulion alliance. Mean values of the ecological indicators (F, R, N) differed between the meadow communities. The greatest disparity was noted for the mean values of the soil moisture indicator (from 6.42 to 7.45). Patches classified in the Filipendulion alliance were developed on the wettest soil substratum, whereas the patches classified in the Arrhenatherion alliance were predominant on a relatively dry substratum. The abandonment of traditional management practices (grazing, mowing) has contributed to transformation of the Molinia meadows, disappearance of characteristic species and succession of shrubs. The Molinia meadow habitat should be conserved by improvement of protection measures (appropriate mowing regime and removal of biomass) to conserve a high species richness and the rare and protected plant species.

Effect of fire on a monodominant floating mat of Cyperus giganteus Vahl in a neotropical wetland

et al. 2015

The rhizomatous Cyperus giganteus, abundant in the Pantanal wetland, can dominate extense floodable areas as monodominant communities. The Jacadigo lake has a large area of C. giganteus, where we performed an evaluation on community structure during two months in 2010, before it was hit by a wildfire which top-killed the vegetation, compared to ten months post-fire. We utilized 40 plots of 1m × 1m, along permanent trails, assessing two strata: the upper, near the inflorescence of adult plants, and the lower, close to the water level. Our results show that fire does not affect dominance of C. giganteus, as it maintained the same cover as before fire; species richness is not much altered either -28 before fire and 34 thereafter. Fire changed the floristic composition, due to the annual variation of species and the ability of some plants to colonize gaps and to regrow after fire from underground organs and seeds. The stratification of the vegetation with characteristic species of upper and lower strata was similar after fire.Keywords: Cyperaceae, floating meadow, diversity, Pantanal, plant succession. Efeito do fogo sobre uma comunidade monodominante de Cyperus giganteusVahl em uma área úmida neotropical ResumoA planta rizomatosa Cyperus giganteus, encontrada no Pantanal, pode dominar extensas áreas inundáveis, formando uma comunidade monodominante chamada localmente de pirizal. A lagoa do Jacadigo, situada na sub-região de Nabileque, possui uma extensa área de pirizal onde foi realizada uma avaliação na estrutura da vegetação durante dois meses no período de 2010, antes de ser atingida por um incêndio que causou perda da cobertura aérea da vegetação e foi comparada com 10 meses de avaliação pós-fogo. Com indicações na literatura de que o rizoma da planta pode favorecer a espécie através de rebrotamento após um incêndio, o objetivo deste trabalho foi avaliar as variações na estrutura da vegetação de pirizal após um evento de fogo. Foram utilizadas 40 parcelas não fixas de 1m × 1m e alocadas sistematicamente através de trilhas avaliando dois estratos: o superior, próximo a inflorescência dos adultos e o inferior, próximo a lâmina d'água. Nos dois meses logo após o fogo, devido ao tamanho reduzido nos indivíduos de C. giganteus foi avaliado apenas um estrato denominado total. Os resultados mostram que o fogo não afeta a dominância de C. giganteus, que se mantém na mesma faixa de cobertura do período anterior ao fogo; a riqueza de espécies não é alterada, 28 no período anterior ao fogo e 34 no período posterior. Após o incêndio, a estrutura da comunidade sofre alteração na composição florística, devido a mudança anual de espécies e a capacidade que certas plantas possuem em colonizar clareiras e rebrotar após o fogo por meio de órgãos subterrâneos e sementes. A estratificação da vegetação com espécies características de estrato superior e inferior se manteve após o fogo, porém com diferença menos acentuada entre as espécies.Palavras-chave: Cyperaceae, baceiro, diversidade, Pantanal, sucessão vegetal.

“…The course of natural afforestation, the spatial character and species composition in successions depend on factors such as physical and chemical properties and moisture conditions of soil, topography, initial cover of herbaceous vegetation, proximity to forest, as well as former land use (Egler 1954;Connell and Slatyer 1977;Tilman 1987;Prach et al 2001a, b;Bartha et al 2003;Alard et al 2005;Daugaviete 2009; Kopecký and Vojta 2009;Rosenthal 2010). Depending on the interactions between these factors, secondary succession creates a suite of heterogenic spatial patterns.…”

Patterns of afforestation on abandoned agriculture land in Latvia

et al. 2012

Abandonment of agriculture land and subsequent natural afforestation have been common features of the contemporary Latvian rural landscape, particularly in the period since 1990. This process affects the structure, ecology and visual qualities of the landscape. The study examines spatial characteristics of afforestation in relation to various environmental factors. The study was conducted in the central part of Latvia, where there is abundant abandoned agriculture land and a great variety of spatial afforestation patterns. The most typical patterns in this area were linear, mosaic, and continuous afforestation, as well as development of afforestation from the forest edge. The results of the study show that the spatial patterns of natural afforestation of abandoned agriculture fields can be very diverse, and do not follow the classical secondary succession model. Afforestation can be delayed by a dense cover of herbaceous vegetation for a period of up to 20 years. There are many interacting factors that affect succession and development of afforestation patterns, such as soil properties, size and configuration of fields, previous land use and also the random nature of plant colonization by seed. Further studies on afforestation patterns would help to understand better their ecological, economic and social effects as well as to determine optimal solutions for the use of abandoned agriculture land.
