Schlumbergera microsphaerica
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Schlumbergera microsphaerica faces severe pressure from habitat destruction as Brazil's Atlantic Forest continues to be cleared for agriculture and urban development. The species' extremely restricted range in the coastal mountains of Rio de Janeiro state makes it particularly vulnerable to localized threats. Collection pressure for the horticultural trade poses an additional risk, as this distinctive Christmas cactus is sought after by collectors. Climate change may further stress remaining populations by altering the humid microclimate conditions this epiphytic species requires.
Habitat
This epiphytic cactus inhabits the humid Atlantic Forest of southeastern Brazil, growing on trees and rock faces in montane cloud forests. It occurs at elevations between 800-1,200 meters in areas with high humidity and filtered sunlight.
