Each element is considered .sej)arately. Commer- cial conifers are considered si<rnificant if they cover f) percent oi- more of the {4'round. Other trees (nonconunercial conifers and hardwoods) are likewise considered si{?nificant down to 5 percent when they are not in nnxtui'c with commercial conifers; bnt when so nnxed their lower limit is 20 ])oi-cent. For all otlier elemeids the lower limit is 20 percent. Fig- ure 5iJ illustrates the densities repi'csented by these limits. They are applied only to the portions of g OQ the elements exposed to the sky; those inider the canopy of taller elements are inventoried by sup- plemental gTound observations if wanted. Vegetation elements are judged on the basis of the space their cro^vns cover. Limitation to the size of areas given recognition is also necessary if uniformity between workers is to be maintained. Individual vegetation - element areas will range from very large to very small, and somewhere between there is usually a size below which delineation is not profitable. The location of this limit will of course be deter- mined by each particular job's recjuirements. For the State's intensification of the California Forest Survey referred to ear- lier, in which the
