M: What does the SES do?
W: The SES is one of the most established bodies in the field of exploration and endeavor and a leading organization for excellence in conservation. Through a worldwide programme of challenging expeditions, the SES initiates and supports scientific, conservation and education projects. Six or more projects are run each year, from studying endangered elephants in West Africa to mapping pre-Columbia archaeology in Panama. SES teams consist of scientists and specialists, free-paying participants and professional staff. Expeditions range in length from two weeks to three months, with teams of 12—45 people aging 18—70. While relevant skills are useful, participants aren’t required to have any specific qualifications.
M: Would you give an example of a current project?
W:40 individuals from the UK, USA and Ethiopia are currently undertaking an expedition in Ethiopia that’ll combine the first descent of the Bashilo River, a tributary of the Blue Nile, was an extensive biodiversity survey.
