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.
Rat poison is a disaster for our wildlife.

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.

A tiny little reddish scops owl (Otus rufescens) I encountered in Coastal scrub in Borneo once. At about 20cm in height they are a cute little owl.

It is absolutely a critical tool in NZ where you have almost no native mammals (I would imagine mopoke are impacted heavily). The point being urban living people use this stuff without thinking or even realising there are consequences.

Depends on the species. Some almost 100% others not so great. Doesn’t really cost much to try 5 or 6 cuttings of a species and seeing what happens. Cutting hormone and keeping them wet really helps.

Winter burning grass trees. Even in the middle of winter they go up with such force.

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.

One of the more amazing wildlife experiences I have ever had. A chance encounter with Wallace’s flying frog (Rhacophorus nigropalmatus). Given It was so special!!

Microhyla borneensis, also known as the Matang narrow-mouthed frog, lays its eggs in pitcher plants. This shot was in Kubah NP and one of several times I have seen them laying eggs.

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.

Swamp Antechinus in the Otways. These chunky little marsupials are feisty little carnivores who seem to be declining across their distribution.

My favourite little mammal that visits our garden. A Krefft’s glider. They love wattles and sap, so provide natives and they may visit you too.

Haven’t been to the Kinabatangan river for so long. Amazing spot to see so much wildlife.

It is an amazing land, and its Indigenous people are also great. Hopefully I can get back there again soon.

One of my favourite species encounters when in Borneo are proboscis monkeys. The Malay name for proboscis monkeys, orang belanda, means “Dutchman.” Originally, the joke was that, with their big noses and portly bellies, the monkeys resembled the Malay peoples' European colonisers.
