In animal and plant populations, local interactions between individuals generate some unique and global spatial patterns. For example, trees competing for light and nutrient with their neighbors in limited area show clumpy spatial distribution rather than random distribution. Here we introduce spatial patterns observed in forests and propose the models which describe their growing mechanisms. We focus on the wave regeneration patterns in subalpine forests, canopy-gap dynamics in a neotropical forest and fluctuating and synchronized reproduction in Beech forests. Theoretical analysis based on lattice models and CMLS was effective at describing characteristic interaction with neighbors and to reproduce observed spatial patterns.
