Invasive alien plant species, such as giant hogweed, himalayan balsam and garden lupin spread easily and reduce growth as well as survival of native plants and animals. They upset the ecological balance and might alter the original range of species. Moreover, the spread of harmful invasive alien species, such as giant hogweed, might threaten ecosystem services and inhibit recreational use of natural environments.

Alien invasive plants are causing significant harm throughout South-Eastern Finland, Leningrad region and St. Petersburg. “Prevention and utilization of Invasive Alien Species – PURE” is a project aimed at raising public awareness about invasive alien species and their negative impact on environment in these areas.

One of the project’s objectives is to develop novel and more efficient measures to combat giant hogweed, but also to find and develop novel ways to utilize it. For that reason, PURE’s experts analyze giant hogweed’s potential for example as a source of ethanol fuel, cellulose, and pectin as well as investigate its energy content and suitability for biogas processes.  Moreover, giant hogweed’s chemical compounds and functional extracts are scrutinized.



  • Organizing awareness rising events for schools, colleges and local communities in South-Eastern Finland, Leningrad region and St. Petersburg
  • Developing more efficient methods for managing giant hogweed
  • Developing new ways to utilize giant hogweed



As an outcome of the project, the target groups in the project area are better equipped to both recognize and prevent the spread of invasive alien plant species. The methods and measures for managing giant hogweed piloted within the project can be scaled to a wider use. Moreover, the novel utilization solutions developed within the project encourage larger scale management measures in the areas of hogweed spread.
