Expedition recap – Melbourne’s Microbats

The expedition team arrived at the Royal Botanic Gardens in the early evening when it was still light, piled high with pillows and sleeping bags and overnight kit. After dumping our belongings in the common room and running through the introductions, we got straight to work on setting up the harp nets to trap our microbats!

We put up around 7 or 8 nets in total, in various spots around the park. Our lead scientist, Casey from San Francisco, knows the most popular flight paths from previous studies, and the nets we used are designed so the microbats fly into the harp-like strings and tumble down into the canvas bags below.

Once the nets were in place, we headed back to the base for a presentation on our pint-sized research subject – learning about the different species, their basic anatomy, range and so on.

Soon, it was time for the first of three net checks. We donned our head torches, grabbed the Anabat (an acoustic device that picks up on the bats’ echolocation) and ventured out into the night.

We checked harp net after harp net, trying not to show our disappointment when each one came up empty. After all, there are no guarantees on a scientific expedition – particularly when it comes to wildlife.

Perhaps the weather wasn’t right. Maybe we were too early – night hadn’t quite fallen.

But then, in the final one, success: our first microbat!

We hurried back to base to process the little guy as quickly as possible. He (it ended up being a semi-juvenile male) was definitely less than thrilled with the whole procedure, but managed to shoot me a grin for the picture below.DSCN9532-001

After we’d released Bat No. 1, we had some downtime until the next round of net checks (there’s a run at midnight and one at three in the morning). To fill in time, we watched some David Attenborough documentaries, chatted amongst ourselves (a Brisbane couple I spoke to had just come back from a National Geographic expedition to the Galapagos!) and shared snacks. We also set up our camper beds – I strategically positioned mine in the kitchen, to be close to the food!

Perhaps due to the weather (we had a storm around five in the morning, and rain threatened throughout the evening), the bat yield was low – but we did get one each time we headed out, bringing the total to two males and one female. We were hoping to see another one of the four distinct species of microbats that inhabit the Gardens, but the three we caught were all the same species (the lesser long-ear).

In the morning, we dismantled the nets and shared a hot breakfast. Casey also gave us the opportunity to go onto mailing lists for other bat research expeditions around Melbourne, which I’d definitely be interested in undertaking.

All in all, it was a great experience – I loved seeing the microbats up close and getting to spend the night in the Botanic Gardens. This is a Melbourne summer activity I recommend to anyone interested in wildlife and wildlife conservation.

Melbourne’s Microbats expeditions run until 28 February 2015. Visit the Earthwatch website to view dates and book.

Some pictures of Golden Wattle in strange morning light. This flowering tree is the official Floral Emblem of Australia, and, at this time of year, you can spot them everywhere – with blossoms ranging in colour from bright, neon yellow to a deep amber hue.

Can you spot the flying insects in the photographs?

Doing my bit for the Great Forest National Park initiative. If you’re in inner-city Melbourne, one of these postcards will be appearing in your letterbox soon (possibly delivered by me!). Sign it, drop it in a postbox – no stamp required! – and The Wilderness Society will deliver them all to Premier Napthine and Opposition Leader Andrews.

Central Highlands

Touring Toolangi

Last SToolangi - Ryan Gray 12unday I went on a tour of Toolangi State Forest (situated in Victoria’s Central Highlands), led by a small team of passionate campaigners from The Wilderness Society Victoria. Persistent rain and leeches aside, it was a breathtaking and, at times, heartbreaking experience. I witnessed the decimation of areas of the forest that had been sacrificed to logging, alongside the magnificence of untouched old growth such as the Kalatha Giant. I saw frogs, fungi and birds; ate pepperberries. I went away wondering how anyone could gaze up at a towering, four hundred year old tree flanked by a dense, ferny understory and not be awestruck. How it was possible to feel comfortable in condemning entire species to extinction if it could be so easily avoided. How the destruction of complex ecosystems in the pursuit of monetary gain could ever be morally or ethically justifiable.

Why protect Toolangi?

Toolangi is a precious habitat to many rare and threatened species, perhaps the most famous being Victoria’s endangered faunal emblem – the Leadbeater’s or ‘Fairy’ Possum – which nests in hollows in old Mountain Ash trees (the world’s tallest flowering tree).

These mountain ash forests have flourished along the Great Divide under rich rainfall patterns. They provide most of Melbourne’s drinking water [and] have been scientifically shown to be among the most carbon-dense forests on Earth…
Great Forest National Park website

The State-sanctioned logging that takes place in Toolangi is for the purposes of producing cheap copy paper. The cost of removing native forest is much higher – for our climate, water supply and wildlife. There is absolutely no excuse to destroy native forest when viable alternatives (such as plantation timber) exist.

How you can help

Here are some photographs that my partner and I took on the tour.
