Central Range Subalpine Grasslands - A Global Ecoregion

About the Area

These disjunct meadow habitats form a tiny ecoregion that surround the highest peaks of Papua New Guinea - a large island nation in the South Pacific Ocean.
A combination of rich volcanic soil produced by the eruptions of active volcanoes on New Guinea and heavy tropical rains help the plant life of the Central Range Subalpine Grasslands thrive. Many endemic plant, mammal, and bird species are found in these sensitive areas.

Local Species

Endemic animals include two mammals - a shrew mouse (Pseudohydromys murinus) and a rat (Rattus novaeguineae) in addition to a number of birds such as MacGregor's bird of paradise (Macgregoria pulchra), Papuanb thornbill (Acanthiza murina), and Wattled ploughbill (Eulacestoma nigropectu).

Much of this ecoregion remains intact, although approximately one-fifth of the fragile ecoregion has been destroyed. Logging in the mountains and pollution in rivers that run through the grasslands are a cause of concern.
