Description: GR02 is an individual tree, distance-independent simulation model for predicting tree and stand growth over time. It performs five major functions during each run: (1) updates diameter at breast height, (2) updates total height, (3) estimates mortality, (4) determines regeneration, and (5) updates crown class.

Keywords: forest growth; mortality; regeneration; volume estimation (stands); volume increment (stands); site index; crown class
