When allowed to spread, it takes over wetlands, choking out the native vegetation and blocking water flow. It sickens most animals if they eat it, and causes skin irritation in humans. Yellow Flag Iris can sometimes be spotted in our local wetlands and rivers, such as the River of Golden Dreams, and the Squamish estuary.
Invasive plants and animals are a growing concern globally. The introduction or spread of invasive species threatens B.C.’s environment, the economy and society, including human health. In order to encourage public awareness and positive action against invasive species across the province, May has been officially proclaimed Invasive Species Action Month by the B.C. government. If action is taken, invasions can be prevented before they happen, and infestations can be controlled or eliminated, thus reducing their harmful impacts.

Something that you could see from your boat
Something that wouldn’t taste good to your goat
Something that spreads by seeds afloat!
Yellow Flag Iris was introduced to North America as an ornamental flower.

“There was a large patch of yellow flag iris in the area near Swanson Cool Pool last summer,” Hodney said. “We worked with a contractor to treat it chemically and it looks like it took out virtually all of it. But we will see if it comes back this year.”
Davis believes it will take a partnership that includes watershed councils, private landowners and area governments to get a handle on yellow flag iris infestations.
