Typha shuttleworthii (Shuttleworth’s bulrush) is a rare species throughout its distribution range including Carpathians. However, a substantial increase in its finds has been noticed in the last twenty years. This study summarises the present knowledge and brings new data on vegetation with T. shuttleworthii occurrence from the western part of the Carpathians (Czech Republic, Slovakia, Poland and Ukraine) with the aims of evaluating the phytosociological affinity of this species and providing new information about the ecology of the relevant plant communities. We found that T. shuttleworthii mainly occurred in marsh vegetation (the Phragmito-Magnocaricetea class) including the Typhetum shuttleworthii association. Some plots also corresponded to transitional stands between marshes and wet meadows of the Molinio-Arrhenatheretea class (Molinietalia caeruleae order). Moisture and soil reaction were identified as principal factors responsible for variation in species composition of the vegetation. Typhetum shuttleworthii was recognised as new for the territory of Slovakia and confirmed in all other countries, Czech Republic, Poland and Ukraine. Our results could contribute to better preservation of the species and its habitats and thus be very important for practical nature conservation.
Europe, threatened species, wetland vegetation
Freshwater habitats, such as shallow field and meadow depressions, ponds or river arms, are very dynamic ecosystems and cover an important part of plant diversity, including endangered and rare plant species (
Therefore, we would like (1) to evaluate the vegetation affinity of the species T. shuttleworthii and (2) to provide new information about the ecology of relevant vegetation types within the western part of Carpathians.
Vegetation, with the presence of T. shuttleworthii, was studied using both the traditional Zürrich-Montpellier´s approach (
Vegetation-environmental relationships were analysed using Detrended Correspondence Analysis (DCA) in the Canoco for Windows package (ver. 5.0;
Soil samples were taken from the uppermost mineral horizon (0–10 cm depth, litter removed) only in Slovak localities. They were dried at laboratory temperature, crushed and passed through a 2 mm sieve. Soil pH and conductivity were measured in a distilled water solution (soil/water ratio of 1/5) using Eutech Instruments PC 650. In addition, altitude, mean annual temperature and total annual precipitation were detected in Slovak localities and they are presented in Suppl. material

Altogether, the first two DCA axes explained 18.5% and 25.8% variability in species data and species-environment relationship, respectively. EIV for moisture was identified as the environmental variable strongly correlated with the first DCA axis (r = 0.72), while EIV for soil reaction was the most correlated variable with the second DCA axis (r = 0.61). Clusters are arranged along the first DCA axis in the following order: 3→1→2 and show preferences for increased EIV for moisture, continentality and nutrients. Species are grouped from moisture- and nutrient-demanding marsh taxa such as Carex rostrata, Eleocharis palustris agg., Sparganium erectum or Veronica beccabunga to taxa of wet meadows, such as Carex flava agg., Lathyrus pratensis or Myosotis palustris agg. (Fig.
The results of our study confirmed that vegetation with the presence of Typha shuttleworthii is relatively heterogeneous in the western part of the Carpathian Mts. Typha shuttleworthii occurs in marshes (Phragmito-Magnocaricetea class) and, in several cases, stands had a transitional position between marshes and wet meadows (Molinio-Arrhenatheretea class, Molinietalia caeruleae order) with the mosaic of marshy, wet meadows and fen species. Similar evaluation of T. shuttleworthii coenology is known from some other European countries. For example, in the Ukrainian Eastern Carpathians and the adjacent regions, T. shuttleworthii grew in marshes and fens belonging to the alliances Phragmition communis (Phragmito-Magnocaricetea) and Caricion atrofusco-saxatilis, Caricion davallianae (Scheuchzerio palustris-Caricetea fuscae;
Our results showed preferences of T. shuttleworthii to marshy and nutrient-rich habitats. Results are in accordance with known data; T. shuttleworthii was recorded in mesotrophic to eutrophic habitats, periodically or permanently waterlogged by shallow water (
Only stands with a high cover of Typha shuttleworthii and a significant portion of marshy species at the expense of meadow herbs were assigned to Typhetum shuttleworthii association (Phragmition communis alliance) in our study. While this association has been reported from several adjacent countries, namely the Czech Republic, Romania and Ukraine (
Most of the available observations of Typha shuttleworthii occurrence in Central Europe originate mainly from the last two decades (e.g.
Typha shuttleworthii is a rare species in several Carpathian countries. The species is critically endangered in Slovakia and the Czech Republic (
