Offshore
islands
"The
Department of Conservation manages or has interest in approximately
220 islands (larger than 5 ha - 12 acres in size) and numerous
small islets and rock stacks."
"Because
islands can be made free from pests, they are good places
for caring for threatened species which can no longer live
on the mainland."
"As
knowledge and technology improves, so does our ability to
remove pests from larger islands. For example, by developing
rat eradication techniques on small islands such as Burgess
Island (159 ha) and Tiri Tiri
Matangi Island (196 ha) we are able to plan for removal
of kiore from Codfish
Island (1396 ha) to protect indigenous ecosystems and
kakapo."
