IB PAN hosted a meeting of the participants of the international IMPAWOS project

More than a year ago, our Institute started the IMPAWOS project to assess the impact of alien and native woody plants on vegetation and soil. The project is financed by the National Science Centre (Narodowe Centrum Nauki) under the Weave programme (Weave-UNISONO call), which is based on the multilateral cooperation between scientific research funding agencies in selected European countries and enables the creation of large international research teams. In the case of IMPAWOS, the team consists of scientists from the Czech Republic and Slovakia (represented by Jan Pergl from the Institute of Botany of the Czech Academy of Sciences) and from Poland (represented by Małgorzata Stanek from IB PAN).

Last week, a two-day working meeting of the IMPAWOS team took place, organised by the Polish side. The meeting aimed to integrate the project participants, who do not usually have the opportunity to work together on a daily basis and to discuss the progress of field and laboratory work, methodological problems encountered and ways of solving them. Thanks to the fact that the meeting was held at the Laboratory of Ecochemistry and Environmental Engineering of IB PAS in Szarów, the guests could learn about the research infrastructure and analytical capabilities of the Polish part of the team, which performs most of the physicochemical and microbiological analyzes of soil in the project. An important item on the meeting agenda was a visit (on the second day) to selected study sites, including those in the Niepołomice Forest, near Jaworzno and Niemodlin, established in monospecific patches of invasive and native species (including Quercus rubra, Quercus robur, Crataegus monogyna and Spiraea tomentosa) and patches of multi-species control vegetation. In total, there are 174 such study sites in the project – located in Poland, the Czech Republic and Slovakia – which translates into thousands of samples analysed. We hope to present the first results of the IMPAWOS project soon.

Below are some photos from the April meeting and several months of field work.
