Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Practise wildlife gardening A site comparison study in one city in the UK found more species of bumblebee in domestic city gardens with lower intensity of management, a measure reflecting the tidiness of the garden and the use of garden pesticides. Solitary bees were not affected by this measure.
