DLNR warns of invasive species in Koolau mountains

HONOLULU (KHNL) - The Department of Land and Natural Resources along with the U.S. Army Natural Resources Program and the Oahu Invasive Species Committee are working to protect Oahu's native plant species and prevent the spread of a highly invasive weed recently found in the Koolau mountains.

In August, Army staff discovered Cane Tibouchina on the Koolau summit in the Poamoho region. 

This aggressive weed is not known to be naturalized on Oahu, although it is widespread on both the Big Island and Maui.

The DLNR says Cane Tibouchina poses a major threat to the Koolau forests.  It thrives in wet areas and spreads rapidly.

The Koolau mountains range provides most of the water for Oahu residents. 

It shelter more than 80 rare or endangered native species, and its streams and underground aquifers supply residents with about 135 billion gallons of fresh water each year.
