The Future of the Cat
Ba Langur is in Our Hands
the Degree of Population Fragmentation - Relocation of Cat Ba Langurs and
Creation of Migration
The remaining population of the Cat Ba langur is severely fragmented into
seven isolated sub-populations at five different locations on Cat Ba Island.
Most of the langur groups are very small and no longer functional in terms
of reproduction - only three groups are currently reproducing.
With this difficult situation, there are no reasons for hope that the langur
population may increase on its own and without massive conservation
The only solution may be the relocation of some individuals and groups inside
of Cat Ba Island, preferably into the strictly protected langur sanctuary,
and the creation of safe migration corridors. These two complementary options
will help to
the current dramatic degree of population fragmentation, to increase the
reproductive output and thus the genetic variability in the Cat Ba
Further funds for this costly emergency measure will have to be secured.
Status for the Cat Ba
One of the main prerequisites for the recovery of the Cat Ba
langur is to avoid further losses to poaching. There is still a risk that
langurs may become the victim of poachers, due to a persistent demand for
langur balm. Conservation specialists expect that despite conservation awareness
programmes the demand for langurs may well increase along with the average
income of local people and visitors. Stringent on-site protection will therefore
have to remain a significant focus of the Cat Ba Langur Conservation Project.
