Scientific knowledge about New Zealand birdlife took a great leap forward today as the Ornithological Society of New Zealand published the Atlas of Bird Distribution in New Zealand 1999-2004.
The atlas was launched today at Government House in Wellington by the Administrator of the Government, Rt. Hon. Dame Sian Elias. Birds are some of the best natural indicators of the health of our environment – an environment we like to promote as clean and green.
President of the Ornithological Society, Professor Richard Holdaway said that the bird distribution atlas has demonstrated dramatic and rapid changes in bird distribution in all parts of the country since the 1970s. As land use has changed, so have the communities of bird species in those areas.
Examples of this included areas that have changed from exotic forest to dairying, and areas that have reverted from cleared land to native scrub. Species that did well in the first habitat have been pushed out as the land was converted. Atlas project Convenor, Christopher Robertson notes that “Green in colour we may be, but these atlas surveys continue to demonstrate that some of that greenness is both increasingly monocultural, and the battleground of territorial invaders among the avifauna. New Zealand endemics are retreating to enclaves where introduced mammalian predators increasingly threaten the food supply, productivity, and individuals of remnant species.” more
