Answer: Some trees and shrubs require acidic soil pH (below 7.0) or they will develop iron chlorosis. Examples include river birch, blueberries, azaleas and rhododendrons. While it is easier to work with plants adapted to your current soil pH, there are amendments you can use to make your soil more acidic.
Under the leadership of British statesman Edward G. Wakefield, the first British colonists to New Zealand arrive at Port Nicholson on Auckland Island. In 1642, Dutch navigator Abel Tasman became the first European to discover the South Pacific island group that later became known as New Zealand.
In addition to longer-term migratory movements of the NZ-born population, a large number of them are frequent flyers back to New Zealand on short-term trips. In 2009-10 there were 297,000 departures of NZ-born residents of Australia back to New Zealand for a period of less than 12 months.he more rapid ageing of the NZ-born population in Australia can be partly attributed to the change over time in the age of arrivals from New Zealand. Of all arrivals of NZ-born people into Australia in the five years to 1989, 11% were aged 40 years and over.
