Correlations of leaf area with length and width measurements of leaves of black oak, white oak, and sugar maple

Abstract

Correlations of leaf area with length, width, and length times width of leaves of black oak, white oak, and sugar maple were determined to see if length and/or width could be used as accurate estimators of leaf area. The correlation of length times width with leaf area was high (r > + .95) for all three species. The linear equation Y = a + bX, where X = length times width, can be used to estimate leaf area where it is not possible or practical to make actual area measurements.
