Threats
On Pohnpei, predation by introduced
species (mainly rats Rattus spp. and cats) and excessive hunting
may have caused some depletion3. The progressive loss or
alteration of habitat is a further possible contributory factor, given a
reduction of 37% in undisturbed upland forest from 1975 to 1995, largely
attributable to the cultivation of sakau (=kava) Piper methysticum3,6.
Long-standing tradition and custom have surrounded its use, but now there
is a more widespread recreational demand with increasing clear-cutting of
1-2 ha plots, reaching to the edge of cloud-forest at c.600 m in some
areas3. On Chuuk, the only remaining semi-original
forest remains in tiny remnants on the higher reaches of a few islands.
