1. The document discusses research on mycorrhizal fungi of local tree species for restoration of tropical peat swamp forests in Sumatra. 2. Progress includes identifying 50 isolates of arbuscular mycorrhizal fungi from natural forests and testing their effects on plant growth. 3. Future research plans include choosing the best 5-10 fungi for mass production and field trials of a restoration model using a biofertilizer consortium containing mycorrhizal fungi, bacteria, and other natural inputs.
