Drought Tolerant Bamboo Species

Last year I started a forest restoration project in the Andes of southern Ecuador. Recently, this idea came to my mind to try to include bamboo into the project as it is very productive, improves the soil, increases structural diversity and attracts wildlife.

However, with only about 800 mm of precipitation and a more or less 6 months dry season, the region is pretty dry... and we are between 1.500 and 2.000 m above sea level. Additionally, I would allow only native bamboo species to be planted... at least a neotropical species!

Does anyone know a suitable species for these conditions? It doesn't have to be very productive under these conditions - the most important thing is that it survives by itself...

Thanks a lot for any help!
