This chapter demonstrates two structural properties of plant communities—canopy leaf area and growth efficiency. It develops four basic premises that (1) canopy leaf area can be related to competition for light, (2) growth efficiency is responsive to canopy leaf area and other identified environmental factors, (3) potential productivity or site capability can be estimated from knowing maximum canopy leaf area, and (4) canopy leaf areas for trees or stands can be nondestructively estimated by determining sapwood cross-sectional area at a convenient reference height. Canopy leaf area and its vertical distribution can be accurately estimated through correlations with conducting sapwood area throughout the crown. Species within the same genera have widely differing ratios of leaf area to sapwood area. To estimate the canopy leaf area on large trees, the linear taper in sapwood area from breast height (1.37 m) to the base of the crown must be determined. |
