Query: A system of state-dependent delay differential equation modelling forest
  growth II: boundedness of solutions   In this article we consider a class of state-dependent delay differential
equations which is modelling the dynamics of the number of adult trees in
forests. We prove the boundedness of solutions for a single species model as
well as a two-species model.
