Figure 4.

Natural areas of Hawai’i do not harbor significant NTM. (A) Representative image of freshwater streams that were sampled for NTM. In these locations, large rocks or boulders lodged in the freshwater stream were sampled at the air-water interface. (B) Representative image of moss that were typically located growing on the surface of large boulders. (C) Representative image of lava rocks sampled. Swabs were wiped across the surface of rocks and in cervices although these surfaces were devoid of NTM. (D) Diversity of NTM species recovered from stream-rock interface biofilms and moss from O’ahu, Maui, and Hawai’i Island.
