The role of kiore in affecting the pattern of succession on Tiritiri Matangi island

[Abstract of a paper read at the Ecological Society Conference, 1983.]

First paragraph:
On Tiritiri Matangi Ishind there are large areas of pasture which have been left to revert. Kiore are one of the main herbivores on the island and they are known to eat large quantities of seed as well as damage tree seedlings. An investigation was begun in 1979 to assess the role of kiore in altering the pattern of succession to forest. A series of exclosures was established in the grasslands, which together with their controls have been recorded annually. It is apparent that kiore have a complex role when taken in combination with the successional change that is occurring. It is evident that some species may be inhibited by kiore whilst others are promoted by grazing on their competitors. The overall effect may be to promote succession.
