Conservationists have launched a fund-raising campaign to complete a 320-kilometre electrified fence that will surround one of the largest forest reserves in East Africa.
The fence will stop endangered wildlife from straying out of the reserve and onto fertile neighbouring farmland, where farmers shoot them to protect their crops.
A thousand square kilometres of the Aberdare National Park in Kenya would be enclosed. The park is home to endangered species including the black rhino, elephants and the Columbus monkey. Many bird species found nowhere else in Africa also live in the park, including the African green ibis, the crowned eagle and the golden-winged sunbird.
