“…This problem is especially marked in seminatural grassland managed mainly by mowing (Gloser and Gloser, 1999). In recent years rapid and aggressive expansion of wood small-reed within grassland communities has led to changes in species composition (Stránská, 2004;Kavanová and Gloser, 2005;Holub et al, 2012) and the loss of their previously high species diversity (Pruchniewicz and Żołnierz, 2017). The expansion mechanism of Calamagrostis epigejos and its effects on species composition still remain poorly understood (Pruchniewicz and Żołnierz, 2017).…”

The aim of this study was to assess how the expansion of Calamagrostis epigejos influences the species composition and diversity of forest, clearing, and meadow communities as well as how habitat factors influence biometric variability and features determining the potential of Calamagrostis epigejos for expansion in the studied communities. The study was conducted in the central part of the Sudetes Mountains (SW Poland). Four types of communities with C. epigejos occurrence were chosen: a beech forest (Luzulo luzuloidis-Fagetum), a Norway spruce monoculture, a clearing community belonging to the Epilobietea angustifolii class, and a mesic mountain meadow of the Arrhenatheretalia order. In each of the studied communities, randomized selection of 10 plots (1 × 1 m) was performed. On these plots relevés were sampled, a biometric study was conducted, and soil samples were collected. The research revealed a significant influence of C. epigejos expansion on the species composition, diversity, and productivity in the herb layers of the studied communities. It also indicated a strong positive influence of sunlight availability and studied physicochemical properties of soil on the expansion ability of C. epigejos.

“…Previous research conducted in mesic meadows degraded by C. epigejos showed positive correlations between the amount of necromass and an increase in the soil's phosphorus and potassium (Pruchniewicz and Żołnierz 2017). However, the stimulating fertilization effect seemed to be inhibited by another mechanism, probably connected with mechanical difficulties in germination.…”

Abstract:Calamagrostis epigejos produces a large amount of litter in patches dominated by this expansive species in degraded meadows. Two studies were carried out in the area of the Central Sudetes Mountains (SW Poland). The goals of these surveys were to address the following questions: How do active manipulations regarding the removal of necromass and C. epigejos tillers, as well as seeding of additional species, influence the meadow species seedling recruitment? How is the organic matter decomposed in the consecutive stages of mountain grassland degradation caused by C. epigejos expansion? How do environmental factors influence litter decomposition? The results of the research showed a significant influence of C. epigejos necromass on the recruitment of mesic meadow species. The influence is connected with the emergence of a mechanical barrier to seedlings, which impedes their sprouting. No relation was found between the degradation stage and the rate of necromass decomposition. The study showed the influence of some environmental factors on the rate of necromass decomposition -in the case of C. epigejos there was a negative impact of exchangeable magnesium forms, whereas in the case of mixed meadow plant litter there was a positive effect of nitrogen and C:N ratio, and negative correlations with Ellenberg's light and soil humidity indices.Nomeclature: Mirek et al.

Thesium linophyllon parasitizes and suppresses expansive Calamagrostis epigejos

Root-hemiparasitic interaction between the dominant grass Calamagrostis epigejos and the hemiparasite Thesium linophyllon was studied to assess the potential of the parasite to regulate dominance of the grass, which is expanding into species-rich steppe grasslands. First, we aimed to identify physiological links between the two species as a principal indicator of the parasitic relationship. Second, we analysed the dynamics of the two species in the vegetation of a steppe grassland at the foot of the Bükk Mountains, Hungary, where their joint presence is recorded in a long-term permanent plot monitoring dataset to detect patterns associated with the parasitic ecological interaction. Numerous well-developed functional haustoria of Th. linophyllon were identified on the root systems of C. epigejos. The joint dynamics of C. epigejos and Th. linophyllon displayed clear signs of the parasitic interaction: (1) the dynamics of Th. linophyllon frequency was positively associated with the initial cover of C. epigejos; (2) maximum recorded cover values of the two species were strongly positively correlated; and (3) the extent of C. epigejos decrease in the vegetation was significantly positively associated with maximum Th. linophyllon cover recorded throughout the monitoring period. We demonstrate that C. epigejos can be parasitized by Th. linophyllon, which restricts abundance of the grass. Th. linophyllon thus has potential to act as a native biological control of C. epigejos in steppe grasslands.
