*Some
native plants had developed defenses against native species like the moa, but were not
able to defend themselves against their new predators*
For example
the Lancewood; when it is young the leaves are sharp, hard and pointed - not very easy or
yummy to eat - so the tree was able to grow. When the Lancewood grew its leaves became
softer and the moa might have eaten some of the leaves but not enough to kill it. Then
animals like the possum arrived in New Zealand and they can eat a tree to death!
The Department of Conservation scientists decide which New Zealand plant species need the
most help. They have a list of the most threatened species. The list is divided into three
groups, A, B and C. The plants listed in the A group are the most threatened.
The list was put
together by the Department of Conservation in 1992.
The list has their
scientific name and their common name (some species do not have a common name).
