BIODIVERSITY

The Forest

Rotorua is fortunate to have this area of fine native forest so close by.  Because of the far-sighted actions of Rotorua people and the government about 100 years ago, large areas of the forest were never logged.  This means that some ancient huge trees are still here for us to see and enjoy.  Some of the large trees are rimu (Dacrydium cupressinum),  pukatea (Laurelia novae-zelandiae), tawa (Beilschmiedia tawa) and rewarewa (Knightia excelsa). 

 

A few minutes up the main walking track is the only surviving large northern rata tree on the mountain.  This has been the subject of a special protection programme.  For details, click here.

The undergrowth is more open than it would have been before humans arrived, because of damage caused by introduced animals. 

However, there are many different species of plants, ferns and fungi.  A very common sight is the tangled smooth black stems of the supplejack (Ripogonum scandens), so named by the pioneers because of its tough and springy nature.  It makes travel through the bush difficult and frustrating.

 

The Wildlife

Introduced pest and predators have severely reduced the numbers and variety of native birds in the forest.  Some that still can be seen or heard on the mountain include tomtits, whiteheads, grey warblers, fantails, tuis, bellbirds, silvereyes, native pigeons, moreporks (native owls) and kaka (native forest parrots).   While some species are very timid, others, such as the fantails, might come very close, attracted by the insects that you have disturbed. 

If it is summer, you could hear the migratory shining cuckoo or long-tailed cuckoo.  As with cuckoos in other parts of the world, they lay their eggs in the nests of other species, who are left to raise the young cuckoo.  Most introduced bird species stay out of the forest.  

Some native species that we hope to be able to return to the forest as we restore it are kokako, kiwi, robin, rifleman, red-crowned parakeet and saddleback.

 

In addition to the native birds, there are many insects and other invertebrates in the forest.
