On the steep hillside near the western boundary of my property, and visible from the highway as you travel south from Oatlands, is a village of small plastic domes. When they first went up, I used to think they looked like extra-terrestrial vehicles just the right size for a baby Yoda. In fact, they are part of an international research program looking at the effects of climate change on native pastures in many locations around the world. The Tasmanian component of the program is run by Prof Mark Hovenden and his team from the University of Tasmania.
