Most wild bee species are solitary ground-nesters or use hollow plant stems, and providing appropriate nesting habitat in gardens is one of the most effective welfare and conservation interventions available to individuals.
Wild bees die in significant numbers from habitat loss that eliminates nesting sites alongside foraging resources. Individual bees that cannot find suitable nesting habitat fail to reproduce, contributing to population decline. Garden design choices — bare soil patches, uncut stems, reduced pesticide use — deliver direct welfare and population benefits to individual wild bees at accessible scale.
