Dr. Todd Cherie, CBC, Canada discussed on Quirks and Quarks

Automatic TRANSCRIPT

And with that, it's time for another quirks in quirks question. This week's question is inspired by the wildfires currently raging in beef, e Janice worn from Montreal asks, what is the impact of forest fires on wildlife, and here's the answer. Hi, my name's Dr. Todd Cherie, Iowa health specialist with parks, Canada, based on the western college of veterinary medicine in Africa, catoon. The impact of major force fires on wildlife can be fairly devastating from the short term, but long term impacts can actually be quite beneficial to some wildlife populations from larger ecosystem perspective. It's when we get wildfires of exceptional severity and rapid growth that animals can't escape that we see that are exceptional mortality events, and most of that is from smoke inhalation. There's a lot of toxic chemicals produced in. Lease oxygen deprivation and death in really fast moving wildfires. So most wildlife species are able to outrun or escape from a fire generally, but slow moving species like porcupines tortoises that don't have that ability to survive. Happily move onto the path of a fire are often once their victims of wildfires and are often found dead in the path of a rapidly moving wildfire. And some animals will have fairly severe burns to large parts of their body. If they can't get out of the way of rapidly moving wildfire, it's very difficult to try and treat those animals in the wild because you have to remove them to try and rehabilitate them, and that can take weeks or months. And it can often be very stressful for wild animal to go into captivity for that period of time. So a lot of the time, if if the injuries are too severe, we ended up having to euthanize. Those animals humanely. And we saw several impacts like that in Keno wildfire in Waterton lakes, national park in September, twenty seventeen. And there were several bears that we had to humanely euthanized after that fire that we're in very poor condition species such as woodpeckers often respond positively to forest fires because often increased food habitat for them in the form of insects and damaged trees provide nesting habitat for them. So in the long term, the impacts of fire can actually be beneficial for some wildlife populations.
