Featured Alien: Brush-tailed Rock Wallaby

Scientific Name: Petrogale penicillatus

How It Came To Hawai‘i :

In 1916 three wallabies were purchased for a private zoo at the 'Alewa Heights home of a Mr. Trent. Neighborhood dogs attacked the new arrivals and the youngest wallaby was killed. The remaining two escaped into the hills to establish a colony of wallabies that still lives in Kalihi Valley.

Impact Since Its Arrival:

Wallabies inhabit a tiny area of O‘ahu and have not affected native animals and plants.

Wallaby Territory

The wallaby once inhabited the area from Nu'uanu to Halawa Valley. People and dogs restricted their range to Kalihi Valley where steep cliffs and dry caves provide protection and shelter.
