TERME PRÉFÉRENTIEL
DENSIOMETERS
DÉFINITION
- A densiometer is used to determine amount of canopy closure. In other words, you are deciding how much of the sky above you is blocked by trees. When looking into a densiometer there is a mirror image of what is above you (it works like a periscope on a submarine). To use a densiometer correctly it must be held level. When looking into the densiometer you can see the trees above you. If more than 50% of the view is covered by branches, leaves, or limbs the canopy is closed. If less than 50% of the view is covered by branches, leaves, or limbs the canopy is open.
