| description | Despite growing global investments in ecosystem restoration, seed supply for native tree species remains a major bottleneck, particularly in the Global South where species diversity is high and natural seed sources dwindling due to land use change.
• Country-specific availability of site adapted tree seed for restoration can be assessed through a new methodology which combines environmental clustering to define seed zones, Maxent species distribution models for target tree species, and data on existing seed sources.
• Application of the method to 21 native pilot species in Bangladesh, India, Indonesia, and the Philippines revealed that, on average,
only 34% of seed zones had designated seed sources, despite the species being widely used in restoration.
• Almost all seed sources (97%) were predicted to remain within the species’ suitable habitat under future climates, showing that informed investments in establishing seed sources can bring sustained benefits.
• The gap analysis methodology enables countries to strategically prioritize areas for seed source development, supporting the achievement of national restoration goals. |
