There are high levels of endemism in the New Guinea flora and this is reflected on Mt Jaya: a total of species (77 % of the total Mt Jaya alpine flora) are endemic to New Guinea, and of these species are endemic to Mt Jaya ( % of the total). fig. 1 Species accumulation data and curves for alpine and montane habitats of the Mt Jaya 1 New from $ New Guinea is a relatively young island, and the alpine vegetation and flora are the younger parts of the vegetation. This young age is reflected in the alpine vegetation by the clear but still unstable › Books › Science & Math › Biological Sciences. New Guinea is the world’s largest tropical island and has fascinated naturalists for centuries1,2. Home to some of the best-preserved ecosystems on Orchids accounted for 20% of the flora in Papua New Guinea and 17% of Indonesian New Guinea. Tree species accounted for 29% of species - by comparison, the
The flora of Papua New Guinea is rich and varied, with habitats ranging from tidal swamps at sea level to alpine conditions. In low-lying coastal areas, various species of mangroves form the main vegetation, together with the beautiful casuarina, sago, and palm.

15 hours ago Scientists have been interested in the flora of New Guinea since the 17th century, but formal knowledge of the tropical island's diversity has remained limited. To The flora of the higher mountains of New Guinea has been the object of several extensive collecting trips in the past forty years. Until quite recently, however, a serious gap in our knowledge was the very scanty information available from the area between Mount Wilhelmina in the West and Mount Sarawaket and Mount Albert Edward in the ://: The New Guinea alpine-subalpine zone is the highest, largest, and wettest such region on any tropical island and it preserves great variations in biodiversity between the individual mountain :// This puts New Guinea well ahead of biodiversity hotspot Madagascar with 16% more species. Of the species found, orchids accounted for 20% of the flora in Papua New Guinea and 17% of Indonesian New Guinea, which is comparable to orchid richness in megadiverse countries such as Ecuador (23%) and Colombia (15%).
