Sweet chestnut: bees and pollination
Without pollinators, sweet chestnut loses a noticeable part of its yield.
How much of the yield depends on pollinators
Modest: 10 to 40% yield loss without pollinators (10-39%)
Without pollinators, sweet chestnut loses a noticeable part of its yield.
Loss without pollinators: 10 to 39 percent
The classification comes from the PLLNT11 dataset of the EU Pollinator Hub, based on Klein and others (2007). It is a range for the crop as a whole; varieties and growing methods can differ, for example self-pollinating varieties or greenhouse growing with bumblebees.
