Magnolia rostrata is classified as Endangered as the area of occupancy (AOO) is estimated to be less than 500 km2, the population occurs over four locations and it is heavily exploited for its bark. The population has significantly declined and if exploitation continues it has a high chance of becoming extinct. There is no up to date data on population size. It is listed as Vulnerable in the China Red Book.
Previously published Red List assessments:
1998 Vulnerable (VU)
