Habitat Losskwp1_web

Forests that ‘Alalā once called home have been changed by human activities like development, agriculture, and ranching. Cattle, sheep, and pigs can consume and destroy understory plants.


Due to the loss of trees and understory shrubs, ‘Alalā have less food to eat and limited cover to hide from predators.
