He has been making work from the landscape since 1958 and has returned to the same landscapes time and again to absorb and relish the appearance and quality of a particular environment. Since 1979 Robert has been making work based upon the landscape surrounding Great Sherberton, an ancient settlement close to Hexworthy upon Dartmoor.  Great Sherberton is a hill farm both open to the dramatic landscape of the Moor and and enclosed by its own great windbreak of beech trees.  The major influences upon Clement's work  include Paul Nash, Eric Ravilious and Graham Sutherland.

Clement works in a number of ways: through making very careful and considered drawings and sometimes by working from these directly onto watercolour; by making doodles and drawings from memories of a place once he knows it well enough to invent its components; by developing ideas for paintings in the studio, working from drawings and photographs and painting in acrylic which allows him to overpaint and glaze one colour upon another.
