What percentage of plants are kept as pollinators in an orchard? (CG RAEO 2017)

• While plants themselves aren't necessarily "kept" in an orchard specifically for pollination, some or all of the trees may be chosen for their flowering characteristics that attract pollinators. Around 10% is a commonly cited estimate for the percentage of flowering plants specifically planted within an orchard to attract pollinators:
-Pollinator mixes: Blooming cover crops planted between rows of trees or around the orchard perimeter. These provide a continuous source of pollen and nectar for pollinators throughout the season, even before or after the main orchard trees flower.
-Hedgerows: Rows of flowering shrubs or trees planted along the edges of the orchard. These can provide habitat and nesting sites for pollinators in addition to attracting them with flowers.

• Why 10% is a reasonable estimate:
-This percentage allows for a balance between maximizing fruit production from the main crop trees and attracting sufficient pollinators.
-It takes into account that some orchard trees themselves may be good pollinators, reducing the need for additional plants solely for that purpose.
