In a remote, steep, and heavily timbered valley in the Victorian Alps, in the summer of 1862-63, a small party of prospectors found encouraging signs of gold at the fork of a tributary of the Thomson River. It was December. By February of the next year an immense quartz reef had been discovered.

This reef – Cohen’s Reef - yielded over 50 tonnes of gold, making Walhalla one of Victoria’s richest and most vibrant towns, and home to thousands: with hotels, shops, breweries, churches, school, jail and its own newspaper. It also had its own photographic studio, headed by the Lee brothers.

Several albums still survive of Walhalla at its peak, providing a fascinating, evocative photographic record of a 19th century mining town; capturing a moment that was to be shortlived.

In 1910 the railway arrived, but too late: the gold was disappearing. The town emptied out and began its long sleep, until the 1980s when restorations began in earnest, and electricity finally arrived in 1998.

The world is changing. Change is a natural part of the Earth’s cycle and of the things that live on it, but what we are seeing now is both like and unlike the shifts we have seen before.

Anthropogenic change, meaning change created by humans, is having an impact on a global scale. In particular, human activity has altered the composition of the Earth’s atmosphere, causing the world’s climate to change.

Already in the state of Victoria we are seeing evidence of this change around us. In the natural world, coastal waters are warming and bringing tropical marine species to our bays. Desert animals are migrating to Victoria. Alpine winters are changing, potentially putting plants and animals at risk of starvation and pushing species closer to the margins. In the world of humans, island and coastal dwellers deal with the tangible and intangible impacts of loss as sea levels rise, bush dwellers live with an increased risk of life-threatening fires, farmers cope with the new normal of longer droughts, and we all face extreme weather events and the impacts of social and economic change.

This Collections and Climate Change digital story explores how Victoria’s scientific and cultural collections help us understand climate change. It focuses on three Victorian institutions - Museums Victoria, the Royal Botanic Gardens Victoria and Parks Victoria. It looks at how the information gathered and maintained by a dedicated community of researchers, curators, scientists, specialists and volunteers can help us understand and prepare for a hotter, drier, more inundated world.

The story is made up of a short documentary film and twenty-one examples highlighting how botanical records, geological and biological specimens and living flora and fauna provide a crucial resource for scientists striving to map continuity, variability and change in the natural world. And it helps us rethink the significance of some of Victoria’s cultural collections in the face of a changing climate.
