In this paper we discuss the structure of recursion operators. we show that recursion operators of evolution equations have a nonlocal part that is determined by symmetries and co symmetries. this enables us to compute recursion operators more systematically. Under certain conditions (which hold for all examples known to us)Nijenhuis are well defined i.e, they give rise to hierarchies of infinitely many commuting symmetries of the operator. Moreover, the non local part of a Nijenhuis operator contains the candidates of roots and coroots.
