Dead trees, Pirongia Forest Park

Possums are selective browsers and defoliate preferred plant species. They have killed some of the canopy trees in this forest, but have had little effect on neighbouring trees. When a large proportion of a tree’s leaves are eaten in each growing season, it can decline in vigour and then die. Over long periods of sustained browsing, the composition of the forest changes – favoured species such as rātā, kāmahi, tree fuchsia and five-finger die and are replaced by plants that are not palatable to possums.
