The occurrence of Beckmannia eruciformis (Poaceae) in Poland. Fragmenta Floristica et Geobotanica Polonica 7: 73–80. Kraków. PL ISSN 1640–629X. ABSTRACT: Beckmannia eruciformis (L.) Host is fairly rare in Poland and about 50 localities of it have been found. They are distributed mostly in the eastern part of the country. Scarce data dealing with the occurrence of the studied species in the west of Poland are now of historical value only.

Distribution of Geranium pyrenaicum (Geraniaceae) in Poland. Fragmenta Floristica et Geobotanica Polonica 8: 93–104. Kraków. PL ISSN 1640 629X. ABSTRACT: This paper presents the distribution of Geranium pyrenaicum Burm. f. in Poland. Some of the locations listed here had already been included in previous publications of the subject. The other stations have never been published before or were originally found by the authors in the area of the Szczecin province.

The author presents the new red list of dragonflies of the Lublin Region, 10 years after publishing the previous edition (Buczyński 1999). The list includes 10 species: 4 species of high risk categories (VU-CR) and 6 of low risk categories (LC, NT). The most endangered are: Coenagrion ornatum (CR), Cordulegaster boltonii (CR), Coenagrion armatum (EN) and Nehalennia speciosa (EN). The scale of threats of dragonflies of the Lublin Region is smaller than in the whole Poland (Bernard et al. 2002) or in the Łódź Region (central Poland) (Tończyk, Szymański 2006). Seriously endangered are the faunas of small running waters and Sphagnum peat bogs. For the protection of dragonflies in Poland, particularly important are populations of Coenagrion armatum (9 in total) as well as one of 3–4 populations of C. ornatum known nowadays in the country which is large and stable.

Paper summarizes six-year long (2007-2012) studies on dragonflies (Odonata) in the county of Pleszew (Western Poland) as well as the eight border sites located in the area of adjacent counties (Fig. 1). The whole area is in the macroregion of the Pohidniowowielkopolska Lowland, in the borderland of two mesoregions: the Kalisz High Plain and Rychwalska Plain. The research was aimed at understanding the species composition of dragonflies and discovering as many sites of rare species as possible. 58 sites lying on the Kalisz High Plain and 85 sites located in the Rychwalska Plain were controlled. Noteworthy is the presence of tens Sphagnum peat bogs in the studied part of the Rychwalska Plain. Dragonflies were caught with an entomoloACgical net and were released after being photographed, exuviae were also collected as well as larvae at one site. Most of the sites were controlled irregularly (mainly between June and August), often only once. The records of particular species were differentiated into three categories: 1) development confirmed (larvae, exuviae, teneral imagines, intensive reproductive behavior - copulations, tandems, laying eggs), 2) development likely (single reproductive behavior, territorial imagines, a large population in the environment suitable for development), 3) development possible (single imagines observed only). In the years 2007-2012 in the discussed area 55 species of dragonflies were recorded (data in this paper), as well as Aeshna júncea given earlier (Bernard, Toñczyk 2011). Total number of 56 species comprise 77% of the species reported in Poland so far (Bernard et al. 2009). For many species important information clearly enriching the knowledge of their distribution in this part of Poland was collected. This particularly refers to the species associated with Sphagnum bogs (Aeshna subarctica, Leucorrhinia albifrons, L. dubia and L. rubicunda), thermophilous species (Aeshna affinis, Orthetrum albistylum, O. brunneum, O. coerulescens, Crocothemis erythraea, Sympetrum fonscolombii and S. meridionale) as well as rare and very rare in south-western Poland (Lestes barbarus, Sympecma paedisca, Coenagrion lunulatum, Epitheca bimaculata and Leucorrhinia caudalis). Protection of the studied Sphagnum peat bogs, where many rare and protected species of vascular plants (Zurawlew, Zurawlew 2010) and the dragonflies (this study) are present, should be one of the priorities of the Forestry Grodziec managing this area. The four tables given in this paper show: studied habitats with the number of species (Tab. 1), a list of the sites of all species and the observed flight period (Tab. 2), the sites with the highest number of species (Tab. 3) and the listing of the occurrence of dragonflies for 15 UTM squares covering the studied area (Tab. 4).
