Several species of Heracleum have been introduced as a cultivated plant and is out of human control in Latvia. Heracleum is a very harmful to humans, especially to children because of causing skin burn. Eradication of the established plant colonies is practically impossible therefore individual efforts are not successful. In Latvia, botanists, plant protection experts and practicians are involved in the solution of this problem. The tasks of the project were as follows: recognising hogweed spread in Latvia; elaboration of temporary recommendations and establishing trials, and performance of observations with the target on science based weed localising measures. After request of the Ministry of Agriculture in 2001, Latvia University of Agriculture collaborating with Latvian Agricultural Advisory and Training Centre performed questionnaire of local power about the spreading of hogweed. Results of the questionnaire showed that total polluted area in Latvia was 12225 ha.
