The wild population of this species is listed as Lower Risk/
Near Threatened by the 2000 IUCN Red List and is protected from
trade under Appendix I of CITES. This threat stems mainly from
decreased habitat due to logging. Field research in Thailand continues
for this species studying wild social behavior, diet and nesting
requirements. This information will be used to improve captive
husbandry as captive breeding rates for Great Hornbills have been
extremely low. The captive population is aging and increased rates
of successful breeding in captivity need to occur or the captive
population will eventually be lost to old age. Knowledge of why
exactly captive breeding rates have been so low is lacking. It
is believed to be a problem with mate incompatibility so the SSP
has begun a re-pairing project to re-mate some of the current
adult individuals with new mates in hope that that will stimulate
breeding behavior in these captive individuals.
