Abstract
This contribution aims to provide a brief overview of the spread of Reynoutria japonica Houtt. plant species in the Bistrita River basin. The paper is part of a larger study that refers to the impact of the most aggressive non-native plants in the Bistrita basin. Our goal is to study and record the presence, distribution and impact of these non-native plant species. The study took place along the entire Bistrita River basin and on the valleys of its main tributaries. This non-native species of Asian origin has experienced an explosive spread in the last decade in many areas of Romania. In the studied area it proves to be particularly aggressive with the riparian areas where it settles. The spread of this species is attributed to several factors that we will discuss here. Reynoutria japonica Houtt. causes major losses from an economic point of view but primarily from a biodiversity point of view.
