Below is a quote concerning some of the issues:

“It is likely that there are some “endangered” woody bamboo species (or genera) in Brazil, particularly those that are found in the severely intervened coastal forests and in highly specialized ecosystems such as the mountains outside of Rio de Janeiro. Based on the distribution maps in American Bamboos, this list certainly includes species of Alvimia, Criciuma and Eremocaulon (coastal forests) and Glaziophyton (Serra dos Orgoaos), and probably species of Athroostachys, Atractantha, some Aulonemia and Colanthelia.

We don’t know an awful lot about the distribution and ecology of these species and others (even more widespread Amazonian and Andean species) to determine their conservation status, but the geographically restricted genera mentioned above are certainly under pressure. Furthermore, with many bamboos it is hard to determine if natural populations are endangered as we can’t easily determine where one individual ends and the next one begins nor do we have information about genetic diversity.

One needs to be careful about publishing information about potentially endangered species as citing specific locations may provide impetus and knowledge to ambitious collectors to go out and get specimens from remnant populations. I recall our discussion about this (with Clark, Judziewicz, LondoƱo) years ago when we were putting together American Bamboos. We opted for silence then but perhaps this position needs to be reassessed.” -Dr. Margaret (Peggy) Stern
