Dartmouth Organic Farm Manager Laura Carpenter prepares to lead inspection team to examine bee hives at the farm’s apiary. They carry boxes, called “supers,” which they hope to add to the top layer of each hive box, if the bee colonies are healthy and need more space in which to make honey. (Photo by Robert Gill)

Farm Manager Laura Carpenter scrapes off a resin-like substance called propolis, which bees use to seal up cracks in their hives. Propolis is thought to have health benefits for humans as well as bees. Carpenter uses a special pry bar to loosen the frames that stand side-by-side vertically in the hive, so she can inspect the cell structures bees are building on the frames. (Photo by Robert Gill)

The beekeepers lift out a frame from the hive box to check that it contains bees at all stages of the life cycle, a sign of a healthy hive. (Photo by Robert Gill)
