Animal modification of native vegetation: Dispersal and destruction of seed in central North Island podocarp forests

[First paragraph...]
Over the past six years studies have been carried out, mainly in dense podocarp stands of Pureora and Pouakani Forests, to gather information about the periodicity, abundance, and soundness of seed crops, the animals that disperse or destroy seed, and how they do so. The ultimate objective is to find out what part each bird, rodent or insect plays in assisting or limiting regeneration of timber species.
