The optimization model described above was applied to determine
optimal forest harvest strategies for case studies in Yen Bai Province,
Vietnam. This area was selected since it is a major timber producing
province in Vietnam and has E. urophylla as a favored species grown
by household foresters. The case studies comprised 10 householdmanaged
forests that were randomly selected from a pool of 271
household-managed forests in Yen Bai Province in 2008 with different
stand number, size and age (Nghiem, 2011).
