Conservationists are calling for help to fund special cameras they say will help stop poaching.
In the past 18 months more than 1,000 rhinos in Africa have been killed for their horn. This is a record high, as Nel has been finding out.
The Zoological Society of London (ZSL) hopes to install cameras at the Tsavo National Park, in Kenya, to protect rhinos and elephants who are being targeted for their horns and tusks.
The cameras transmit images, detect the vibrations of passing vehicles and can help rangers locate where gunshots are fired.
ZSL is bidding for funding to help them pay for the cameras to be installed.
