Tropical & Subtropical Dry
Broadleaf Forest

The drier forest of Wallacea are often overlooked...


The drier forests of Wallacea are found in the large country of Indonesia and the tiny new country of East Timor. They dominate the natural landscape in a group of islands often known as the 'Lesser Sundas'.

Their rainfall and vegetation is in contrast with the wetter jungle of south-east Asia and New Guinea. They look quite similar to the drier tropical woodlands across northern Australia, and are seasonally dry for the same reason, as they are located in the rain shadow of the Australian continent. Moister trade winds that come from the south east in the southern hemisphere dry season are sucked dry as they travel across the continent. Only in the summer wet season does the area get significant rainfall. At this time, the previously sparse brown vegetation erupts into green.

My first trip after the virus is as Expedition leader in Tasmania with Coral Expeditions (March), followed by my role as biologist guest lecturer on the Great Barrier Reef (April) and Expedition Leader in the Kimberley (in May). If you can't go travelling until everything settles down, then until then, here I am doing online guided walks for Noble Caledonia and online lectures for Silversea.
