DescriptionAn instrument known as the spherical densiometer has been found adaptable to permanent-plot estimates of relative canopy closure or density in forest and range ecological studies. The device is more compact and simpler to use than previous ocular-type instruments. Because the instrument has a curved reflecting surface which results in observations from lateral as well as overhead positions, a problem of overlap in readings occurs when adaptation of the densiometer to permanent-plot work is attempted. Some modifications were developed to eliminate this difficulty.
