eucalyptus adaptations to water loss

vertical orientation

hang vertically rather then horizontally, limiting exposure to sunlight during hottest parts of the day, reducing evaporation

waxy cuticles

Impermeable to water, preventing evaporation and water loss. Reduction in light absorption leads to reduction in the stimuli that opens the stomata, further reducing water loss

leathery texture

tough leaves retain moisture efficiently

stomatal control

closing stomata during hottest hours to prevent transpiration

leaf shedding

under drought conditions, shed leaves to drastically reduce water loss through transpiration

deep taproots

roots can reach deep depths accessing water reserves when surface moisture is not available

extensive lateral roots

widely spreading lateral roots that absorb moisture across large surface areas whenever it rains
