Abstract
Mathematical expressions of overstory-understory relationships in the literature have been hampered by models which do not really fit the data. A growth function Y = H + A (1 - e -BX)M + 1 provided a curve which corresponds with the theoretically expected behavior of the overstory-understory relationship, although 4 parameters instead of the usual 2 are required.This publication has 2 references indexed in Scilit:
