Recovering magnolia populations in northern Vietnam

Conservation Problem

Populations of several highly threatened magnolia species in northern Vietnam, including Critically Endangered Magnolia grandis, are declining due to logging of adult trees and removal of young seedlings by farmers growing cardamom in the forest understorey.

Project Goal

Our aim is to protect and enable the recovery of Magnolia grandis and other priority magnolias in northern Vietnam, through patrolling, planting and reducing the impact of cardamom planting in critical habitat.

Why this/these species?

Magnolias are among the world’s most ancient trees and are greatly admired for their stunning goblet or star-shaped flowers. However, magnolias are under severe pressure around the world, with nearly half of all species threatened with extinction. In northern Vietnam these species have lost much of their forest home to rice paddies, farms and pasture, and are now found only in a small number of protected areas.

Although these protected areas are providing magnolias with a level of protection, limited law enforcement and management on the ground means that the future of these species, including the Critically Endangered Magnolia grandis, is uncertain. Magnolia trees continue to decline due to illegal logging, while cultivation of cardamom in the forest understorey leads to extensive weeding of magnolia seedlings preventing natural regeneration.

Without our support, illegal logging and cardamom cultivation within protected areas in northern Vietnam would continue to endanger the long-term viability of critical magnolia populations and their habitats.

What are we doing about it?

Working with FFI’s Vietnam Programme and our local NGO partner, the Center for Plant Conservation (CPC), our strategy is to introduce regular monitoring, patrolling and reinforcement planting to Tung Vai Watershed Protection Area, where the world’s largest population of the Critically Endangered Magnolia grandis is found.  The site is also home to the Critically Endangered Tonkin snub-nosed monkey, providing a unique opportunity to protect and restore a habitat of vital importance for threatened plants and primates. Unfortunately logging and cardamom farming are significant issues at this site. We are taking the following key approaches:

  • Provide support to community conservation teams to monitor and patrol critical habitat areas that include Magnolia grandis trees
  • Carry out targeted reinforcement of Magnolia grandis and other trees, increasing the population size of this threatened species, and helping to restore primate habitat.
  • Identify areas of critical habitat and develop agreements with cardamom farmers to protect magnolia seedlings within these areas
  • Work with  local farmers to support adoption of more sustainable cardamom cultivation (helping farmers to use higher yield crops in smaller areas of land)

Key achievements

We have achieved major milestones towards the reinforcement and long-term protection of threatened magnolias in northern Vietnam. With only 150 known individuals globally, population reinforcement of Magnolia grandis is essential in reducing extinction risk. Of the 1,145 seedlings planted so far, 90% have survived, providing a major boost for the species. A further 1,500 seeds have been collected, which are now germinating in a local village nursery.  The establishment of patrol teams, including a Community Conservation Team, and regular monitoring and patrolling specifically focused on the magnolia trees, ensured that the remaining Magnolia grandis population is protected from logging.
