Phoebe is a University of Melbourne Masters student supervised by Dr. Kevin Rowe at MV. She is studying post-fire distribution and ecology of the Smoky Mouse in the Grampians National Park.

In September 2013, I moved to the Grampians, pitched a tent and set out to see how the endangered Smoky Mouse, Pseudomys fumeus, was faring in the aftermath of the February 2013 Victoria Valley fire. After three soot-covered months, I’m back in Melbourne enjoying modern comforts like showers and instant boiling water.

I began my surveys at the site where, prior to the fire, we found a healthy population of Smoky Mice in the November 2012 Museum Victoria Bioscan. By September regrowing bracken ferns and eucalypts added a splash of green to the blackened landscape. In spite of the devastation, I caught several healthy Smoky Mice including some of the same individuals we’d caught the previous November! The ecological significance of this discovery alone was cause to celebrate.

Between my first capture in September and my final trapping night in December, I surveyed 46 sites in and out of the burn scar across the Victoria Range in the Grampians. At six of those sites, all within the burn scar, I found Smoky Mice living in the rocky habitats. The mice in these populations were not just surviving, they were healthy and breeding. I caught adults weighing as much as 70 grams but I also found tiny juveniles newly emerged from the nest weighing only 12 grams.

While I was looking to find Smoky Mice, my trapping methods meant I also caught a number of other small mammal species (and a few reptiles). I was lucky enough to encounter Swamp Rats, Rattus lutreolus, Heath Mice, Pseudomys shortridgei, Agile Antechinus, Antechinus agilis, and Dusky Antechinus, Antechinus swainsonii. The highlights of my small mammal by-catch were two tiny Eastern Pygmy Possums, Cercatus nanus, that found their way into my traps.

The last three months were physically and mentally challenging, hiking up mountainsides in the rain and hail, being snowed on one day and sweating in the heat the next, but it was worth every unpredictable minute. I feel so privileged to explore the beautiful, rugged wilderness of the Grampians National Park and to have encountered so many remarkable species. The Parks Victoria staff provided a wealth of logistical and emotional support. It’s great to know that our parks are in such capable hands and that the Smoky Mice of the Victoria Range are thriving in spite of the fires.
