Papuan Casuarina Limestone Forest

These are mainly broad-leaved forests with an upper story dominated by the near endemic Casuarina papuana (Casuarinaceae). They commonly occur on limestone or ultrabasic rocks from almost sea-level well into the lower montane zones, but Casuarina papuana has a wide ecological tolerance and is not confined to any particular rock type. It also tends to be a pioneer species often colonizing areas destroyed by fire. On the other hand, it does not live for very long, and more mixed forests eventually take over. This is also supported by the fact the Casuarina papuana does not regenerate under dense shade.
