Considered as one of the world’s biodiversity rich countries, Papua New Guinea ranks among the megadiverse countries and the last frontiers for biodiversity conservation. This land of diversity hosts 6-8% of the global species, hosts one-sixth of known languages, and rivals Borneo, the Amazon and the Congo in terms of biodiversity wealth. PNG comprises the eastern half of the largest tropical island on earth, along with hundreds of smaller outlying islands, and its land mass only occupying less than 0.5% of the world’s total
Wild populations of PNG’s freshwater crocodile (Crocodylus novaeguineae) and saltwater crocodile (C.porosus) have been subject to management programs designed during the early 1980’s.
So much literature has been written about PNGRIS (Keig and Quigley 1995) and the usage of its datasets for various analysis Nix, H. A et al (2000) even to this day. From these references it is known that PNG occupies approximately 464,100 km2 of landmass excluding the maritime area out of which Peat-soils occupy 17% (~78,830 km2). From visual inspection of the PNGRIS Peat-soils Map and Peat Depth obtained from Tropical SubTropical - CIFOR Peatlands Imagery showed degradation of Peat-soils especially in the Highlands of Papua New Guinea.
