What happened to bee colony collapse?
The number of colonies reported to be lost to CCD has been declining since 2008, but overall colony loss rate is still a major concern. For the past eight years, about 30% of colonies have been lost each winter, but that number dropped to 23% in 2013-14.
What was found from Doctor Lehrman’s studies in Springfield MA?
8. What was found from Doctor Lehrman’s studies in Springfield MA? More bee diversity occurred when homeowners mowed their lawn every two weeks, instead of every week or every three weeks.
