Crater Lakes National Park, Queensland, Australia

 

This small (10 km2) park contains two crater lakes of volcanic origin, Lake Barrine and Lake Eacham, at 720–730 m asl, surrounded by the last relatively intact stands of Queensland’s tallest rainforest type, complex mesophyll vine forest on uplands1. Here, “complex” refers to the diversity of life forms and structures, e.g. plank buttresses and epiphytes, “mesophyll” to relatively large leaf sizes and “vine” to the abundance of robust lianes2. The park is a part of the Wet Tropics of Queensland World Heritage Site (for more about the Wet Tropics, see Opens internal link in current windowDaintree National Park).

 

Annual precipitation is about 1400 mm and average annual temperature about 20°C 1. The tree flora is diverse and species identification challenging. The most abundant genera include Argyrodendron and Ficus. A particular feature is two giant Opens internal link in current windowAgathis microstachya (bull kauri) trees at Lake Barrine, called Twin Kauri Pines.
