Guin Wogan of the University of California, Berkeley noted that the collections are important in the understanding the biology of the species. Also mentioned is the research activity of the California Academy of Sciences (CAS) in San Francisco, California, the Smithsonian Institution in Washington D.C., and Burma's forestry department about snakes.
