A case for controlling the distribution of the tree daisy Olearia lyallii Hook.F. in its type locality, Auckland Islands.

Olearia Lyallii occurs on forested islands south of mainland New Zealand. It was apparently introduced accidentally to the Auckland Islands by sealers in the early 19th century. It is still spreading, but is not yet found beyond Port Ross, three of the Port Ross islands and the north-east shores of the main island. It supplants the dominant forest tree, Metrosideros umbellata, because it has greater tolerance to partial shade and salt spray; it grows faster and taller and is not browsed. Olearia forest is floristically simpler than Metrosideros forest.

Resources and man.

As there are fashions in words there are certainly fashions in books and this is another of those dealing with population, resources, production and the environment. However, at this point the simile breaks down; words may only be used, but in a book even the most fashionable subject can be treated in almost an infinite number of ways.
