Deciduous trees can tolerate more defoliation than evergreens. True or False?

• A. True
• B. False
• C. It depends on species
• D. Not enough info

Answer: (A)

Deciduous trees can tolerate more defoliation because they are built to regrow foliage each growing season. After leaf loss, they can rapidly produce new leaves and rely on stored carbohydrates to rebuild canopy, especially since their life cycle includes a period of dormancy and resumption of growth. Evergreen trees, on the other hand, keep needles year-round, so losing foliage reduces photosynthetic area for a longer time and recovery is slower, making them less able to withstand defoliation. While tolerance varies by species and the amount of defoliation, the general trend is that deciduous trees endure more defoliation than evergreens. Therefore, the statement is true.
