Population
There is no precise data about population size and dynamics for this species at present. However, the species has been
described as common in Marau area, in a report written in 1995 (Governo do Estado da Bahia 1994/1995).

Threats
The Atlantic coastal rainforest of Brazil has been severely degraded and only about 6% of it remains intact. It has been
devastated mainly by the establishment of cacao plantations and sugar cane fields as well as by other types of farming (Prance
et al. 2000).

Conservation Measures
There are no known conservation measures specifically for B. santosii, however the species is known to occur within the
protected areas network at present. Samples of seed of B. santosii should be collected and stored as an ex situ conservation
measure. Further field work should be carried out in the areas where the species occurs to better understand its population size
and trends. The species has been listed as Rare in the 1997 IUCN Red List of Threatened Plants (Walter and Gillett 1998).

Rationale for the Red List Assessment
B. santosii is endemic to Brasil, occurring in the coastal forests of Bahia and Sergipe states. The estimated extent of occurrence
(EOO = 80,500 km2) doesn't meet the threshold for a threatened category at present. However, the species is of some
conservation concern, due to the fact that its natural habitat has been severely degraded and fragmented throughout conversion
of natural vegetation to plantation and that the species is facing a consistent reduction of it potential suitable habitat. Further
botanical survey should be carried out to better define population size and trends and to make sure that the reproductive
success of the species is not compromised yet.
