A shorthand system for the rapid, precise description of vegetation. For example, in Christian's and Perry's (1953) scheme, A, B, and C respectively denote trees, shrubs, and herbs; 3, 2, and 1 indicate size as tall, medium, and short; density is recorded as x, y, and z, indicating respectively dense, average, and sparse. Average layer heights are also appended. There are many other such schemes, of varying complexity.
