Considering them as indicators of habitat qualities, the results would imply that the qualities of the urban and suburban forests were due to a vast range of deciduous forest, especially broad-leaved, and possibly also to a lower intensity of forestry than in rural areas, resulting in a sufficient number of mature and decaying trees.
