Greater Negros-Panay rain forests

The Greater Negros-Panay rain forests is a tropical and subtropical moist broadleaf forests ecoregion located in the Indomalaya biogeographic realm, covering South and Southeast Asia, extending from the Indian subcontinent to southern China, spanning approximately 34,856 km². Classified under the WWF ecoregion code IM0114, 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 Greater Negros-Panay rain 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 Greater Negros-Panay rain forests contributes to the broader biodiversity patterns of the Indomalaya realm.

Geographic Distribution

The Greater Negros-Panay rain forests extends entirely within Philippines. This geographic range places it within the Indomalaya realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Greater Negros-Panay rain forests supports a range of wildlife, including Aloe Yucca (Yucca aloifolia), Anil de pasto (Indigofera suffruticosa), Arrowleaf sida (Sida rhombifolia), Artemisia (Artemisia vulgaris), Beauty Of The Night (Mirabilis jalapa), bell bauhinia (Bauhinia tomentosa), Black mimosa (Mimosa pigra), Black Nightshade (Solanum nigrum), and 42 more species.

Conservation

Like many tropical and subtropical moist broadleaf forests ecosystems, the Greater Negros-Panay rain 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.
