Deadly snakes on the move and pets at risk as weather warms up

Like just about everyone who has spent their life on the land, Lyndall Scott is no novice when it comes to Australian reptiles.The retired farmer has had plenty of encounters with snakes on her property in Borenore, just outside Orange in the NSW central west."We've had yellow-bellied and red-bellied black snakes, this is reasonably common in our area," she said.Lyndall Scott with her granddaughter and her dog Gus.

(ABC South East SA: Elsie Adamo)Ms Henning said it time spent trying to identify what sort of snake was involved could be counterproductive."We're very lucky to have a polyvalent antivenom available that treats for most brown and black snake species," she said."But otherwise it isn't necessary … the time is better spent getting to the vet clinic quickly."While the symptoms for each snake bite can vary, the common presenting signs seen are wobbliness, weakness or paralysis, hypersalivation, change to gum colour, vomiting, diarrhoea, dilated pupils or discoloured urine.Ms Henning said many animals acutely collapse, then have a period of apparent "recovery" immediately afterwards."This can be a sign of lethal envenomation and is usually followed by a second life-threatening collapse soon after, so not a sign to sit back and wait," she said.Increased snake bite riskAccording to the World Health Organisation's snake distribution mapping, many deadly snake species are predicted to increase in abundance and come into contact with more people due to climate change.The research found that many snake species would shift their ranges, meaning people would encounter new kinds of snakes in many areas.Stefanie Earl runs Wild Woofers Snake Catching in Bathurst.
