Abstract

Aims

The cultivation of Sphagnum mosses in paludiculture has high potential for the use of formerly drained peatlands under wet conditions. The aim of this study was to evaluate the plant species composition and vegetation structure of Sphagnum cultivation sites in comparison with near-natural donor sites and rewetted sites without Sphagnum introduction.

Location

Central Europe, northwest Germany close to the Dutch–German border.

Methods

The treatments (rewetting with and without Sphagnum introduction) and a near-natural donor as a reference were each studied at three different sites. At each site, bryophyte and vascular plant species composition as well as parameters of vegetation structure were sampled in 40 randomly positioned plots of 25 cm × 25 cm.

Results

In addition to the highly frequent Sphagnum, several further plant species typical of bogs were introduced. At two cultivation sites, the species composition showed a high degree of similarity to the near-natural donor sites, whereas the third site was more similar to the rewetted sites without the introduction of Sphagnum biomass. Rewetted sites were species-poor in comparison with all other sites. Apart from a high cover of Sphagnum, the vegetation structure at the cultivation sites differed significantly from the near-natural donor sites.

Conclusions

Sphagnum cultivation sites can be used to grow donor material for peatland restoration and contribute to species conservation by providing substitute habitat for bog-typical and threatened plant species.

泥炭栽培地植物种类组成及植被结构

在潮湿条件下，在古农业中种植泥炭藓具有很大的利用潜力。本研究的目的是比较近自然供体地和未引种的复湿地的植物种类组成和植被结构。位于欧洲中部，德国西北部，靠近荷德边境。在三个不同的地点分别研究了处理(引入和不引入Sphagnum的再润湿处理)和接近天然供体作为参考。在每个样地25 cm × 25 cm随机定位40个样地，取样苔藓植物和维管植物种类组成及植被结构参数。除了常见的泥炭属植物外，还引进了其他几种典型的沼泽植物。2个样地的物种组成与近自然供体样地高度相似，而第3个样地的物种组成与未引入Sphagnum生物量的复湿样地更为相似。与所有其他站点相比，复湿站点的物种较少。栽培地点的植被结构与近天然供体地有显著的差异，除了有较高的泥炭覆盖外。泥炭地可作为泥炭地恢复的供体，为泥炭地典型和濒危植物提供替代生境，有助于物种保护。

期刊介绍： Applied Vegetation Science focuses on community-level topics relevant to human interaction with vegetation, including global change, nature conservation, nature management, restoration of plant communities and of natural habitats, and the planning of semi-natural and urban landscapes. Vegetation survey, modelling and remote-sensing applications are welcome. Papers on vegetation science which do not fit to this scope (do not have an applied aspect and are not vegetation survey) should be directed to our associate journal, the Journal of Vegetation Science. Both journals publish papers on the ecology of a single species only if it plays a key role in structuring plant communities.
