Cats are lovely pets but;

And there’s other reasons to discourage cat ownership..

Predators are disappearing world-wild, including from our seas. On land this can have unforseen effects. The left diagram below is what we have done, and the right is what the science suggests we should do. The problem is these decisions would effect on-farm income.

However agriculture and conservation can work together. Rabbit hemorrhagic disease virus in arid South Australia released 4 threatened study mammals from feral predation. The result was the 4 species’ removal from the IUCN Red list.

So next time you see a spider or cockroach in your cupboard remember your own actions and decisions also have consequenses.

Big spiders and big snakes in the Big Desert

I’ve just returned from a field trip to the Big Desert National Park with research scientist Tim Doherty(Deakin University, Melbourne) surveying small mammals in long unburnt Mallee vegetation. Seven days without a shower! My job was to grab a handful of very smelly fish, carry them 100 meters into the bush and bury them near our infra-red night video cameras. Hot days, copious flies and rotting fish is not a fun combination. Now add, no shower…. I was walking blowfly nirvana!

The trip enabled me to see much of the park which though named “Big Desert” was semi-arid bushland, very much burned and now fire scarred in most places. Finding areas which were not burned for many years took much of our precious time.

Dr Tim checks out the vegetation, note the soft sand.

Increasing our understanding of small mammal vegetation preference aids  our scientists’ efforts in limiting extinction. This study is related to what you can see here:
