Figure 4

A visual comparison of the current stratification system versus the prior system. Figure 4a shows the current strataification system (with the old stand boundaries as well). The 0.04 ha grid cells are shaded to represent their different strata with redder cells having less volume than green cells. Figure 4b shows the prior stand delineation for this same area with the true-color imagery of the area as the base layer to show actual forest conditions. Note that the new strata grid-cells do correspond to the old stratification in areas where there are clear stand boundaries but in mixed forest conditions the new system can distinguish different forest conditions that the original strata system lumped together. This new strata system also does a much better job of mapping landings/clearings and wide road areas (most of the red and orange cells).
