Banff National Park is using one pest to fight another.
To fight the looming threat of a weed called Toadflax that is infesting the park, park rangers have released hundreds of small Serbian beetles called weevils to kill them.
“A weevil is a very small insect that lays its eggs inside the plant and reduces the plant’s distribution by stressing it out.”- Jane Park, fire and vegetation specialist with Parks Canada.
Parks Canada is protecting native plants to prevent the weevils from overtaking them. The release of the weevils will be heavily monitored, and if it is successful, it will be considered for future weed outbreaks.
