According to research studies, invasive species promote uncontrolled changes in the ecosystem, endangering agriculture and negatively affecting the economy. The research aim is to examine the spread of Sosnowsky's hogweed and the opinions of local residents on the control of this invasive species in Rezekne Municipality. Sosnowsky's hogweed spreads in Latvia as a whole, including Rezekne Municipality. In the rural territory of Berzgale of Rezekne Municipality, Sosnowsky's hogweed has spread the most. A survey of randomly selected territories did not identify considerable differences in the spread of Sosnowsky's hogweed between 2012 and 2016. According to a survey of residents living in Rezekne Municipality, the residents chose mainly the cheapest methods to control Sosnowsky's hogweed, and only a small proportion of them believed that they had sufficient knowledge of control methods for Sosnowsky's hogweed. The present research employed the following research methods: monographic and descriptive, analysis, synthesis, statistical analysis and a sociological method – a survey.
