Terrestrial Ecosystems

Terrestrial ecosystems include all plants, animals and invertebrates -- both native and nonnative -- that exist above the high tide line in islands of the Pacific.  Terrestrial systems are found on both high (of volcanic origin) and low (formed by coral) islands.  They include human interactions and uses of living resources that affect species or ecosystem processes, for example the introduction (intentional or unintentional) of nonnative species.
