Summary:

This article discusses patterns of plant death and regeneration in which the author will discuss the spatial dynamics of some Pacific forests in which stand-level dieback has been shown to be a natural and recurring phenomenon. This discussion will include their regeneration patterns while keeping in mind the equilibrium concept and the disturbance regimes and processes that may lead to dieback. The author will give four examples of spatial patterns of natural dieback and regeneration in pacific forests such as the Shimagare phenomenon in Japan, the nothofagus dieback in New Zealand, the scalesia dieback in the Galapagos, and the metrosideros rain forest dieback in Hawaii and will discuss two dynamic processes in dieback forests such as disturbance regimes and stand development and stress. He will also include an hypothesis that will explain why stand-level dieback occurs in some natural forests but not in others.
