These images were taken in the Republic of Congo where the authorities recently conducted the country's annual ivory survey. As a CITES member state, Congo is required to conduct a count of its confiscated ivory each year by the end of February.
Keeping ivory under lock and key can be risky because of its perceived value. As the folks from WCS Congo detail on their new blog, the country is currently one of eight African states that uses Stop Ivory's digital Stockpile Management System (SMS), which helps the government better keep track of, and thus safeguard, its inventory. Ultimately, it makes it harder for items to disappear unnoticed.
