This note considers cooperative irreducible systems of ordinary differentialequations admitting a $C^{1}$ first integral with positive gradient. We provethat all forward or backward nonwandering points are equilibria. We obtain alsosome results on the global phase portrait of such systems. The main tool ofproof is a canonically defined Finsler structure with respect to which thederivative skew-product dynamical system is contractive.
