Hey everyone,
I’m John, a wildlife ecologist from Australia. Work on impacts of fire and climate on small mammals, impacts of rodenticides and wildlife, and urban ecology. Have come here in the hope of some of the old banter that used to exist on Twitter.

New paper.
Dynamics of the introduced house mouse in the Gariwerd-Grampians landscape in response to fire and climate. With climate change driving more regular fires and changes in rainfall, we show one of the species to benefit will be the house mouse.

Why we need better management of rodenticides post. A #rentokil bait station at the interface af a pond with wildlife and a public swimming pool. All rodenticides must be within 3m of a building. This is at least 20m from a building and in a place where it will attract the attention of wildlife.

It bothers me so much that every building I encounter has rodenticides outside them. The bait in these boxes out doors will more than likely spread to the food chain. We need to do so much better and ban second generation anticoagulant rodenticides (SGARs). Do better APVMA!!

Could the APVMA be any more clear how they view scientific evidence of rodenticide poisoning of our wildlife? Time to ditch our regulator? #APVMA

So apparently the APVMA is supposed to release the recommendations of their review into rodenticides in Australia this month (only a few days left). It is over a year late and we still have no indication if they will do anything.

When you reach for the rat poisons, stop for one second and think about where it goes. Often not rats and mice. Here we demonstrate it ends up in possums, many are then eaten by predators like powerful owls.
Please avoid second generation anticoagulants

Fire not only resets our biological infrastructure but also has significant economic costs. Fire is good for ecosystems in the right dose, but the more frequent mega-fires we are seeing in the Grampians are not good.

My personal native plant nursery. Australian native daisies, emu bush, banksia and grevillea from cuttings. Masses of grass trees grown from seed over many year. I give most of these away to people in my street willing to plant them on their nature strips. 1 plant at a time will make a difference

Just a little reminder on rat poisons. They don’t just kill rodents! Second generation anticoagulant rodenticides are killing native predators the world over. Think twice, maybe even thrice before using SGARs.

This is a male agile Antechinus. He has rather large “nuts”, and like most dasyurid marsupials will live a short life and go out in a flurry of sex. After a short breeding season all the males die off. Generally referred to as going out with a bang.
