The Odonata fauna along the Lavant and the surrounding still waters of the European protected area Untere Lavant near Mettersdorf was collected at 13 sampling sites from March to October 2018. The aim of this survey was to evaluate the restoration measures of 2010, 2014 and 2015 focusing the odonatological-ecological status by collecting data of 936 individuals belonging to 32 dragonfly species on 16 observation dates. As a result, eight species can be stated certainly, 18 probably whereas two

... re considered to be possibly autochthonous. During the course of the Koralm Tunnel construction work in 2010 both compensating and compensatory measures were implemented along the regulated stretch of the Lavant in the so called compensatory biotope "Lavantumlegung". At the same time the course of the river from river kilometer 15.8, got modified along 1400 m downstream, furthermore stagnant water bodies just off the Lavant were built. Moreover, in the course of the LIFE Project Lavant "Lebensraumvernetzung für gefährdete Kleinfischarten" the "Laufverschwenkung Mettersdorf" was realized at river kilometer 16.1. Odonatological data was analyzed with the Odonata-Fließgewässer-Zonations-Index (OFZI). According to the evaluation results of 1.67 the survey area can be classified with a good odonatological-ecological status. After comparing the data with the Austrian and Carinthian Red List it can be stated that twelve species can be classified as Endangered, Vulnerable or Near Threatened. Due to the study, Ophiogomphus cecilia listed in the Fauna-Flora Habitat Directive at Anax II and IV is proved to be resident in survey area. Furthermore, there is a first resident record for Orthetrum coerulescens for the Lavanttal. For the first time an adult Gomphus vulgatissimus male and an Anax parthenope male could be recorded in the Lavanttal.
