Poison ivy in Italy
Poison ivy is found throughout North America, the United States and the mountainous areas of Mexico. The plant may have been present in Italy for some time even if the cause of its introduction, nor the certainty of its presence has not yet been clarified.
The people most at risk of "contact" are those who live in close contact with nature, especially those who go trekking or climbers who, in their climbs, can come into direct contact with climbing ivy! It is precisely the climbers who would have identified the presence of this plant in our country.
