A pod is lowered onto and then immediately removed from the crown of a coniferous tree, using a helicopter, at a time when the cones of the tree have opened. The pod has a conical and open-bottomed frame supporting a screen side wall. The base of the frame supports an internal annular open-top trough. The raising and lowering of the pod, coupled with the downdraft of the helicopter, causes mature seeds in the open cones to become airborne. The airborne seeds are contained by the side wall and drop into the trough for recovery.
