In 1947, it was the only "National Research Center" in Madagascar and worked in collaboration with the Overseas Scientific and Technical Research Office (ORSTOM). In 1993 after having its status, it took the name "Parc Botanique et Zoologique de Tsimbazaza (PBZT)" until today and under the supervision of the Ministry of Higher Education and Scientific Research.

It contains Angiosperms, Gymnosperms, Ferns, Mosses and some species of Lichen. The oldest known collection is dated from 1831. The total number of herbarium specimens to be conserved is estimated to 258,000 of which 200,000 are mounted with 177,000 classified in the cabinets and 23,000 unclassified and the remaining 50,000 are unmounted. Currently 850 type specimens were recorded. The Herbarium TAN is one of the largest places that conserves the biodiversity of Madagascar.
