In 2005, the volunteer quarters, staff quarters and the new dens were built to accommodate the ever increasing personnel at Tacugama and 16 more young chimpanzees. An onsite veterinarian joined the team at Tacugama for the first time. In order to promote the conservation of wild chimpanzees in Guinea and Sierra Leone, a nationwide education program was launched in collaboration with the Jane Goodall Institute, funded by USAID.

On the 6th of October, Tacugama Chimpanzee Sanctuary hosted more than 500 guests to celebrate our 10th Anniversary. It was a great honour for us to host His Excellency, Dr. Alhaji Ahmed Tejan Kabbah, the President of the Republic of Sierra Leone. We were also delighted with the presence of many Government Ministers, ambassadors, international guests, heads of NGOs, village elders and children.
