Monitoring Free-Living Honeybee Colonies in Germany: Insights Into Habitat Preferences, Survival Rates, and Citizen Science Reliability. [PDF]

open access: yesEcol Evol
In this study we examined the habitats, nesting sites, and survival rates of free‐living colonies through personal monitoring of nest sites in Munich (N = 107) and the coordination of Citizen Science monitoring across Germany (N = 423). On average, only 12% of the personally monitored colonies in Munich survived annually, a figure that aligns well with
