Spring is spring, but Sosnowsky's hogweed is on schedule.

Sosnowsky's hogweed is a perennial plant of the Apiaceae family, posing a threat not only to local flora and fauna but also to humans due to the presence of photosensitizing substances – furanocoumarins – in its stems and leaves. Upon contact with skin and mucous membranes, these substances cause severe phytophotodermatitis when exposed to ultraviolet radiation.

In its natural habitat, this species grows in the North Caucasus region and is a Caucasian mountain-forest and subalpine meadow species.
The high invasiveness of Sosnowsky's hogweed is due to its biological characteristics, in particular, its high competitiveness, rapid growth, high fertility (up to 30-40 thousand seeds per plant), the ability of seeds to spread by water and wind, as well as their long-term viability in the soil (up to 10-12 years) without losing germination capacity.
In its growing areas, hogweed practically completely displaces native vegetation, forming plant communities uncharacteristic of the territory in composition and appearance. According to scientists' estimates, the rate of its expansion and the growth of its habitats is 15-20% per year, and if the full range of measures is not implemented in a timely and high-quality manner today, then in 3-4 years the costs for this type of work will increase by more than 2 times.
Many years of experience in combating invasive plant species in various countries around the world using different control methods show that only bringing land into economic circulation is the only real opportunity to curb the further expansion of these plants and ensure the preservation of ecosystem biodiversity.
