With respect to current distribution of dragonflies the Lublin region (south-eastern Poland) belongs to one of the best studied areas of the country. However, the larger studies that have been published so far are mainly related to peripheral areas of this ground and the state of knowledge on its central part is still incomplete. The author presents data on dragonflies of one of the most naturally valuable areas of this ground – Kozłowieckie Forests protecting the biggest forest complex of the vicinities of Lublin city. The studies were conducted in the years 1999–2006 (mainly 2004–2006) at 35 study sites. 45 dragonfly species were found. The fauna of Kozłowieckie Forests is typical of forest areas under moderate anthropopression (meliorations, regulations, water pollutions, fish pond management in river valleys). The activity of a human being had double impact on the fauna: either negative or positive. From one hand tyrphobionts have disappeared, the number of some tyrphophiles and rheophiles has decreased or vanished. Lacustrine species and odonatocenoses have appeared as well as the conditions for the development of thermophilous refugial species like Lestes barbarus, Erythromma viridulum, Aeshna affinis, Anax imperator, Orthetrum albistylum, Sympetrum depressiusculum, S. fonscolombii. Kozłowieckie Forsests are not the area of great importance for dragonfly protection. They can be treated as the refugium of species diversity for the central part of the Lublin region, however, they do not play the important role in protection of threatened species or odonatocenoses.
