Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the habitat?Global distribution across temperate, tropical, and boreal forest ecosystems
2. What is the applications?Forest inventory, ecological modeling, silvicultural planning, champion tree identification, environmental stress assessment
3. What is a tree crown and why do scientists measure it?The crown is the leafy top of a tree where photosynthesis happens. Scientists measure it to learn how healthy the tree is and how it fits into the forest.
4. How do scientists find the crown spread of a tree?They measure the distance between opposite driplines, the outer edge where water drips off. This gives the horizontal diameter of the canopy.

Dendrometry: The science of measuring trees, including their dimensions and growth.
Dripline: The perimeter of a tree's crown, marking the furthest extent of its canopy.
Crown Volume: An estimation of the three-dimensional space occupied by a tree's crown.
Silviculture: The practice of controlling the growth and composition of forests to meet specific objectives.
