How can plants be carried to an offshore island

These organisms carry pollen grains from the anther to the receptive part stigma of the plant to allow pollination to occur. Our native birds are attracted to the flowers of these trees and carry pollen from flower to flower on their beaks as they seek nectar, pollinating flora as they move. In New Zealand, birds are important pollinators. Two native species of mistletoe Peraxilla spp.

Science is a process of trying to figure out how the world works by making careful observations and then making sense of these observations. Scientists have used this knowledge to inform their understanding of ecosystems and the interactions between species within these systems. Many seeds located within these fruits have coats that must be weakened by chemicals as they pass through the digestive system of another organism. Native plants are dependent on birds for successful seed dispersal and regeneration.

As many of our native birds are now confined to small predator-proof mainland sites or offshore islands, what might the future hold for our native flora, which is so dependent on this process? In New Zealand forests, only 12 species of bird have been responsible for the majority of tree seed dispersal, but many are now extinct:. As the weka is a flightless bird, it can only scavenge the fruit that has fallen from the tree and could not cover the same distance that a bird of flight would be able to.

New Zealand native birds have a key role in the pollination and seed dispersal of our native flora. Birds are essential to ensure the future of our native bush ecosystem in generations to come. It is also home to brachiopods; primitive clam-like animals that have been bypassed by evolution, remaining unchanged in over million years.

Bottlenose dolphins, New Zealand fur seals, Fiordland Crested Penguins and little penguins are also resident in the fiords. An easier way to witness the spectacle of Black Coral and other unique species is with a visit to the Milford Sound Underwater Observatory. The best time to see them is July - November. Fiordland National Park is now over 1. Fiordland is most famous for hiking and walking. Te Anau and Manapouri offer a huge range of activities to do on the lake.

There is a short foreshore walk up to 30 minutes linking Milford Sound Lodge to the boat terminal, passing the airport on the way. There are several walks to do along the Milford Road. You can also take a guided half-day walk on the Milford Track from Milford Sound, pre-bookings essential. Natural Wonders Takahe - Douglas Thorne. Takahe - Douglas Thorne. Another win for conservation in Fiordland A critical preservation project is currently underway In the tussock basins of the Murchison Mountains in Fiordland.

It was thought to be extinct for more than forty years before being rediscovered in the mountains of Fiordland in Kakapo - Pania Dalley.

Kalaupapa National Historical Park protects habitats ranging from the ocean to the upland rain forest. All support a wealth of fish and wildlife resources. Nearly 20 federally-listed threatened and endangered species of plants and animals have been identified within the park.

The relict loulu forest on Huelo Islet is typical of lowland forest ecosystems in Hawaii before human settlement. Sediment cores from widespread archaeology studies show that loulu palm forests predominated in Hawaii's prehistoric lowlands. Polynesian colonists arriving in about AD introduced new competing plants, the Polynesian rat, and cleared and burned these native forests for agriculture.

Thereafter the endemic palm forests went into steep decline. Today they survive intact only on this tiny Huelo Islet, safe from rats that eat the seeds and alien competing plants. Carter's panic grass. Tetramolopium rockii NPS photo.
