According to experts, Opuntia cacti currently make up 23-30% of the low vegetation in this region. Biologist Jan Tryponez of the Valais Nature Conservation Service said that in some areas cacti can cover up to a third of the available surface.
The presence of cacti has also been reported in neighboring Alpine regions, including Ticino and Grisons in Switzerland and Aosta Valley and Valtellina in Italy. Environmentalists believe that with snow cover rapidly decreasing due to global warming, invasive species may achieve ideal conditions to spread, and the number of snowy days below 800 meters above sea level in Switzerland has halved since 1970, according to a MeteoSwiss report. . Ecologists described the situation as “unprecedented in the last six centuries”.
