• Albizia is large tree that can grow up to 150ft. tall
• Extremely fast growing, up to 15 ft per year (possibly the fastest growing tree in the world)
• Its brittle limbs are prone to “sudden branch drop,” where branches suddenly fall without warning
• Produces large numbers of seeds/pods easily dispersed by the wind
• Capable of altering the entire natural native Hawaiian ecosystem
• Albizia’s extraordinary growth rate combined with its significant seeding capabilities can lead to a dense canopy of trees that can prevent the growth of native Hawaiian forest plants and trees
• Quality bird habitat is diminished when Albizia choke out native trees and forests
• Its brittle nature leads to sizable fallen trees and limbs which can block roads and waterways
• Additionally, its sizable fallen trees and limbs can cause damage to housing/property, and public infrastructure, including damage to utilities potentially leading to power outages
• Large more mature trees are costly to remove potentially costing thousands of dollars
• Albizia trees can quickly spread into and take over farms, grasslands, and freshly cleared areas
• Albizia trees change soil composition (by adding excess nitrogen) which inhibits growth of native forests
