Restoring insect diversity enhances biodegradation and pollination services in forest ecosystems

Insects play a pivotal role in ecosystem functioning by mediating essential services such as biodegradation and pollination. This study, conducted over two years (2023 and 2024), assessed the impact of insect diversity restoration on biodegradation and pollination in a protected forest. Data collected before and after restoration indicated a significant increase in insect-mediated ecosystem services. The abundance of decomposer insects like Collembolans increased from 5.02 % to 7.50 %, while wood-decomposing beetles rose by 15.16 % and 23.00 %. The key pollinators such as Bombus spp. (bumble bees) and honey bees showed notable improvements in activity on crops. These findings highlight the necessity of conserving insect diversity for ecosystem balance and productivity. Restoration strategies including habitat preservation and eco-friendly practices are vital.
