A METHODOLOGICAL CRITIQUE OF VEGETATION RECORDING SYSTEMS.
Abstract
Since the initial development of the Dansereau scheme for describing and recording the structure (or physiognomy) of vegetation in 1951, a number of significant modifications to the scheme have been introduced, both by Dansereau and others. Notable variants include those by Mills and Clagg (1963, 1964) and by the Waterways Experiment Station. These variants are examined for consistency and logic, for the flexibility of each, and for the study of possible alternatives. Suggestions for improvements, providing for greater reliability and repeatability in field observations are made, including modifications of crown outline classes, absolute heights of vegetative layers, redefinition of leaf size and leaf shape, and so on. Examples of the use of the system(s) for the estimation of biomass are included. (Author)
