Former TV-am reporter Cheryl Campbell has been made executive director for the Television Trust for the Environment (TVE).
She is replacing Robert Lamb, who is stepping aside after leading the group for almost 20 years.
Campbell, who started out on the Lancashire Evening Post, has worked as a reporter in BBC regional radio, as well as reporting for Television South West and Tyne Tees Television. Since 1995 she has worked in the charity sector as head of public communications at Christian Aid.
TVE, which was set up in 1984 by the United Nations Environment Programme, Carlton Television and the World Wildlife Fund for Nature, raises awareness of the environment, sustainable development, health and human rights issues through television.
It makes two series, Earth Report and Life, broadcast on BBC World.
