Abstract

Dynamics of beech forest are studied by a lattice-structured population model to investigate the effect of understory dwarf bamboo. Assumptions are: The forest is composed of many patches, or stands, of beech, each corresponding to an area covered by a single canopy tree. The state of a stand is characterized by the age of the oldest individual. Within a stand, tallest trees have strong competitive advantage over shorter ones in terms of the likelihood of becoming a canopy tree. Understory dwarf bamboo inhibits the formation of seedling bank of beech tree. Reproduction and subsequent wither of dwarf bamboo occur in regular intervals synchronously over a large area, creating periodic opportunity of regeneration for beech. The analysis confirms a very strong effect of understory dwarf bamboo on the beech forest dynamics, as previously suggested. The periodicity in reproduction and gap formation of beech trees, the rate of spread of bamboo after its synchronized death, and the finiteness of the number of stands are also discussed.
