Spongiosperma oleifolium
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Spongiosperma oleifolium faces severe pressure from agricultural expansion and urban development across its limited range in Madagascar's eastern rainforests. Slash-and-burn agriculture for rice cultivation has fragmented its habitat into isolated patches, while logging for timber and charcoal production continues to degrade remaining forest fragments. Climate change poses an additional threat through altered precipitation patterns that affect the humid microhabitats this species requires for reproduction.
Habitat
This endemic Madagascan species inhabits humid lowland and montane rainforests of the eastern escarpment, typically found in understory environments with high moisture levels and dense canopy cover. It occurs at elevations ranging from sea level to approximately 1,200 meters, preferring areas with rich, well-drained soils and consistent humidity.
