Abstract:
An artillery rangę in Nowa Dęba (Sandomierska Basin, SE Poland) was investigated in the years 1998-99. Its central part has self-desert character; the rest is covered with forest. Six localities were studied: a stream (locality no. 1), oligotrophic and dystrophic fire-fighting rese- rvoirs near the stream (2), transitional peat bogs (3, 5), a fen (6) and dystrophic reservoirs between dunes (4). (Fig. 1). 36 dragonfly species were recorded (Tab. 1). Taking into account the relatively smali number of water bodies and their smali diversity the number of species is high. Two species from the national Red list (Aeshna juncea, Cordidegaster boltonii) and one protected (Sympecma paedisca) were found. Species assemblages in stream and peat bogs were very valuable. It can be stated that the rangę is important for dragonfly protection. This conclusion agrees with the results of entomological studies in other military areas in Poland, Czech Republic, Germany and Belarus. They show that existing and old military areas should be evaluated and protected if it is possible. The State of knowledge about dragonflies of Sandomierska Basin was also discussed. To 90s there were only some contributions with 40 species recorded. 11 papers have appeared sińce 1994 and the number of species has increased to 57 (Tab. 2). But it is still impossible to entirely characterize of the dragonfly fauna of the region. Modern studies were conducted only in its northem and north-eastern parts and the older data is incomplete (Fig. 2). Basing on literaturę from neighbouring areas it can be stated that at least 66 species occur in Sandomierska Basin. The region is an important refugium of endangered dragonflies: 7 of 11 protected species and 9 of 16 species of the national Red list were recorded. Probably there are: 9 protected species and 12 from the Red list. Species diversity and natural species assemblages in the region should be protected too.
