Manihot hahnii
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Manihot hahnii faces severe pressure from agricultural expansion and cattle ranching activities that fragment and destroy its native habitat. The species' restricted range makes it particularly vulnerable to localized threats, while collection pressure for horticultural trade has further reduced wild populations. Climate change poses an additional long-term threat through altered precipitation patterns affecting the dry forest ecosystems where this endemic cassava relative survives.
Habitat
Manihot hahnii inhabits dry tropical forests and scrublands in its restricted range, typically growing in well-drained soils on slopes and rocky outcrops. The species is adapted to seasonal drought conditions and occurs in areas with distinct wet and dry seasons.
