Found only in Vietnam the critically endangered Delcour’s langur is severely threatened by limestone quarrying. They live in family groups on karst limestone which is being mined for cement used for construction. @faunafloraint and partners are acting fast to secure a new reserve for an additional 40 langurs discovered in 2016. It really is now or never for a species with fewer than 300 animals existing today. You can help by visiting the Fauna and Flora international website to donate or become a member.
