Lord Howe Island subtropical forests

The Lord Howe Island subtropical forests is a tropical and subtropical moist broadleaf forests ecoregion located in the Australasia biogeographic realm, covering Australia, New Guinea, New Zealand, and the surrounding Pacific islands, spanning approximately 14.4 km². Classified under the WWF ecoregion code AA0109, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences warm year-round with high annual rainfall, typically exceeding 2,000 mm. The dominant vegetation consists of dense, multi-layered canopy of broadleaf evergreen trees. These conditions create the foundation for the ecological communities found within the Lord Howe Island subtropical forests.

Ecological Significance

These forests are the most biodiverse terrestrial ecosystems on Earth, hosting an extraordinary density of plant and animal species per unit area. Epiphytes, lianas, and a rich understorey characterise the complex vertical structure. The Lord Howe Island subtropical forests contributes to the broader biodiversity patterns of the Australasia realm.

Conservation

Like many tropical and subtropical moist broadleaf forests ecosystems, the Lord Howe Island subtropical forests faces threats from deforestation, agricultural expansion, logging, and climate change. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
