Months into my first English winter, I started having dreams about the Australian wilderness. The images were so vivid and specific that I jotted them down. I had a recurring dream about looking at the sea from a high vantage point, somewhere along the south-east Queensland coast that I had always taken for granted. There was “all manner of ocean life”, I noted: dolphins jumping in the shallows; two whales, a mother and calf, out in

 From Wikipedia Edited by -Amal Udawatta, The  red-eyed tree frog ( Agalychnis callidryas) , is a species of frog in the subfamily  Phyllomedusinae . It is native to forests from Central America to north-western South America. This species is known for its bright coloration, namely its vibrant green body with blue and yellow stripes on the side. It has a white underside, brightly red and orange colored feet, and is named after its distinctive bright red eyes. Red eyed tree frog  is an arboreal frog with long limbs and webbed toes. They mate and reproduce near ponds, and are therefore found in lowland wet areas found in tropical forests Like all the frogs in its genus, they are nocturnal and do most of their hunting for insects at night. The males of this species are smaller than the females, and they display non-random mating patterns which suggest female choice for specific types of male. Despite its bright coloration, the red-eyed tree frog is not poisonous. Its bright coloration

When it comes to restoring them to their natural state there is one hero with remarkable powers - the beaver. Wetlands store water, act as a carbon sink, and are a source of food. The Ramsar Convention on Wetlands says they do more for humanity than all other terrestrial ecosystems - and yet they are disappearing at an alarming rate. The main problems are agricultural and urban expansion, as well as droughts and higher temperatures brought about by climate change. But if you have a river and a beaver it may be possible to halt this process. These furry sharp-toothed rodents build dams on waterways to create a pond, inside which they build a "lodge" where they can protect themselves from predators. Their technique is to chew tree trunks until they fall, a
