EARLIER STORY:

District of North Vancouvercouncil is voting to ban the use of rodenticides on its municipal properties because of the threat it poses to local wildlife.

Council will vote on the ban Monday, and urge theprovince to consider B.C.-wide prohibition ofanticoagulant rodenticides.

Rat poison has been widely criticised for how it moves through the food chain after it's ingested by a rat. Trace amounts are found in local wildlifeand can be harmful topredatorslike owls, according to a council report.

"Anticoagulant rodenticides cause animals to suffer and die from primary and secondary poisoning and pose risks to human and planetary health," wrote Coun. Megan Currenin the report.

A 2009 study on 164 owls in Western Canadafound that 70 per centhad residues of at least one rodenticide in their livers. Researchers found that nearly half of those owls had multiple rodenticides in their system.

Curren says rats that ingest the poison don't die right away and tend to move around sluggishly, becoming easy targets for their natural predators.

"I hope this is the start of the provincial and federal ban of something that's been known to cause a lot of harm," she told CBC News.

Detected in owls, coyotes

Members of the environmental advocacy group Owl Watch B.C. are applauding the motion. Co-founder Elise Roberts is among those who have been lobbying for a ban on the North Shore.

Roberts was motivated after coming across a dead owl near North Vancouver's Blue Ridge Creek.

"I really did grieve for that owl," said Roberts."I guess it took finding one to really get going on this campaign."

North Vancouver is known for its populations of barred, great horned and pygmy owls. According to thecouncil report, "anumber of local owls have been confirmed, via toxicity testing, to have ingested fatal amounts of rodenticide."

Rat poison has also been found in higher-order predators likeweasels and coyotes, as well as scavenger species like birds and squirrels.

Roberts says the use of rat poison outdoors in communities like North Vancouver contradicts Canada's guidelines for hazardous materials.

"These rodenticides should not be put anywhere where wildlife can be impacted," she said."On the North Shore we have wildlife at our doorstep everywhere."

Pushfor province-wide ban

Rodenticide isregulated at the provincial level, so municipalitiescannotissue a sweeping ban. The Ministry of Environment warns against its use, noting that can be harmful to wildlife.

The B.C.SPCA urges people torodent-proof their homes instead of relying on rat poison.

The District of North Vancouverplans to petition the province for a B.C.-wide ban on the products, which are typically used by the commercial sector.

"I think this is a huge step in the environmental protection regime," said Marie Turcott, a member ofOwl Watch B.C. "This is acknowledging that we have to weigh these risks that are posed to the environment, to wildlife, to our pets more seriously."

Turcott says she hopes other municipalities will consider implementing bans.

"The district has an opportunity to be a big leader especially if they're planning to push such a ban and put pressure on the province," she said.
