New Caledonia (NC) is a biodiversity hotspot sheltering terrestrial ecosystems of high ecological and conservation value including tropical dry forests, rainforests, and maquis.
Subgenus Austenina, or the fusca group, lives in primary forest belts (rainforest, savannah, or coastal forests).
The PPSRNP contains a spectacular karst limestone landscape and eight different forest formations; forest on ultramafic soil, forest on limestone soil, montane forest, freshwater swamp forest, lowland evergreen tropical rainforest, riverine forest, beach forest, and mangrove forest.
Terrestrial palaeobotanical records indicate a shift from widespread Araucarian forests and rainforest, including 'tropical' taxa now extinct in the region, to a landscape by the end of the Late Pliocene similar to that of the present day with a mosaic of Eucalyptus Acacia Casuarinaceae sclerophyllous forests and open vegetation, with local areas of Nothofagus-dominated cool temperate rainforests.
Unfortunately this proxy cannot be applied to most wet tropical forests, as rainforest species composition and structure is well known not to be in equilibrium [11].

This abrupt transition is maintained by fire, which prevents or reverses invasion of the sclerophyllous forest by rainforest plants.
By reducing the acidity of the soil (as at Cremaq), Brazil has turned the cerrado into one of the world's great soyabean baskets.A new study by the World Bank says the world has half a billion hectares of land with fewer than 25 people per square kilometre living on them (this excludes land on which farming would be impossible, such as deserts, forests and rainforests or the Antarctic).
Weyerhaeuser faced a particularly broad coalition consisting of the International Brotherhood of Teamsters, the Native American people of Grassy Narrows First Nation, the Boreal Forest Network, Rainforest Action Network and others.
Swoon over sweeping vistas of Pacific beaches, Andean cloud forests, Amazon rainforests, Highland Indian villages, colonial cities, snow-topped mountains and vast volcanos.
