"It needs to be focused and effective. It must also be – and this is a growing concern worldwide – reducing the harm of animal welfare."
Strychnine's opponents say that their poison does not meet one of these levels.
Wolf Awareness has spread documents that show – along with 1,200 weddings killed by different ways in Alberta from 2005 – at least 257 other animals were poisoned, including 44 foxes and grizzly gap.
These numbers appear to be conservation, said Sadie Parr of Wolf Nutrition, as strychnine lives in the food net.
"Anything that puts a pigeon leg too suffers from this terrible result before death."
Many scientists believe that poisoning can be done. reducing mice.
"You're killing a biggest wolf, the pack will divide, sometimes up to three or four hours," said Gilbert Proulx. "Then you will have four rubbish next year instead of one."
The scientists of the Alberta government say that the raptor's behavior, which also uses gunning on the air, has preserved a caribou on a landscape that has been & # 39 ; influencing the development of energy and forestry.
Alberta The environmental speaker Matt Dykstra tells farmers that also use strychnine to control crackles – even though they are in the same way. measure the amount used against the floor face.
Dykstra wonders how someone can be measured.
"It's not something that can be explained by a degree of accuracy," he said.
A federal agency has a & # 39; Using an interpretation created by the Royal Society of Australia for Hardening to Livestock. It describes "impossible management programs and prevents or disrupts methods of pain, suffering and disruption to targeted animals and not targeting it."
Proulx said that strychnine is now used to control predators in most countries; Commonwealth and European or the largest US states.
Parr confirms that difficult scenarios need to be made on busy landscapes. But some decisions, she said, were passing science.
"Now the day and age are where we can do what we want to do, we say, what we want," she said. "This is a conservation issue but it is also a moral cause."
