Pro Natura ha designato la chiocciola fasciata (Cepaea nemoralis) animale dell’anno 2025. Molto diffusa e presente in tutta la Svizzera, questa “preziosa produttrice di suolo” crea le basi sulle quali letteralmente poggia la nostra vita.
Chiocciola fasciata animale dell'anno
Telegiornale 03.01.2025, 20:00
La chiocciola fasciata si può trovare nei boschi radi, nei parchi, nelle siepi e nei giardini. Con la sua conchiglia di 2,5 centimetri di diametro è tra le specie di lumaca indigene più grandi, indica l’associazione ambientalista in un comunicato diramato venerdì.
È stata scelta per sensibilizzare sulla protezione del suolo, un patrimonio vitale ma minacciato. Queste lumache e altri organismi producono 0,1 mm di nuovo terreno ogni anno, ma eventi estremi e sfruttamento agricolo eccessivo possono causare perdite significative di suolo.
Gli appassionati dell’orto non devono temerla, anzi! Come la maggior parte delle 254 specie indigene di lumaca, la chiocciola fasciata si nutre soprattutto di piante avvizzite e morte, saltuariamente di carogne. Questo la rende utilissima.
