Many variables affect intensity of light on forests’ floors.
Plots with high crown density and basal area, for example, might

specifically height, crown ratio, size, and density, could be
related to the pattern of red pine mortality and to the light
environment. One evaluation of the stand characteristics was
done by Team Gray Van in the measuring live-crown ratio and tree
height. The results show… However, The Other Guys found that…
Team Xtreme shows how… (can you also make these verb tenses

plantation had more intense sunlight o
