The heavy anthropic activity has as a result the invasion of allochtones in the natural damaged ecosystems from Romania and the whole Europe. This fact has a negative impact over the genuine evolution and development of natural biocenosis. Invasive species are the real main threats for the agro-biodiversity. Datura is a genus of nine species of poisonous vespertine flowering plants belonging to the family Solanaceae. All species of Datura are poisonous, especially their seeds and flowers. Datura wrightii is an invasive species whose range has expanded greatly in recent years in Romania. According to studies in our country, the species Datura wrightii was identified for the first time in Romania from the Galati County - Foltești, Tg. Bujor, Umbrarești. This species has an aggressive character on biodiversity and we found it in ruderal areas, garbage storage on land, vacant lots, edges of the road. The species has an important anthropogenic impact on herbaceous and woody plant communities and therefore on some types of community interest habitats. D. wrightii has also been used to induce hallucination for recreational purposes. Ingestion of plant material can induce auditory and visual hallucinations similar to those of Datura stramonium.
