Un intervento di contrasto alle neofite invasive ha preso il via lo scorso 23 febbraio sull’Isolino (Isola dei conigli) delle Isole di Brissago. Lo scopo dell’intervento promosso dal Dipartimento del territorio (DT) è quello valorizzare le isole e proteggerle: infatti, a differenza dell’Isola Grande, sulla quale è situato il Giardino Botanico, sull’Isola piccola la vegetazione cresce spontanea e una parte è formata da specie alloctone (piante non del posto, ma arrivate dalle sponde, come per esempio le palme), che si teme possano sopraffare quelle indigene.
L’operazione di eradicazione totale ha pure uno scopo sociale: a parteciparvi, insieme ai selvicoltori del DT, sono stati anche gli allievi dell’Istituto delle Scuole Speciali Cantonali del Sopraceneri.
Lotta più decisa contro le specie esotiche
