These fruits are an important food source for various birds and mammals in its native habitat.

Habitat and Distribution

Noronhia emarginata is endemic to Madagascar, where it is found in a range of habitats from lowland forests to mountainous regions. It has a preference for humid environments but can also be found in drier forest areas. The species' adaptability to different ecological zones has allowed it to spread across a significant portion of the island. However, like many native Malagasy species, Noronhia emarginata faces threats from habitat destruction and deforestation, which have led to concerns about its conservation status.

Ecological Role

In its natural habitat, Noronhia emarginata plays a crucial role in the ecosystem. The fruits of the plant are a vital food source for a variety of animals, including birds and mammals, which also aid in seed dispersal. Additionally, the plant contributes to the biodiversity of the forest understory and serves as a habitat for numerous insect species.

Conservation
